Thanks, I have not seen that incantation mentioned. People are suggesting to turn off power management, which I have just done tonight.
Turning off power management made it last a lot longer, almost four hours before it dropped again. I tried out your suggestion too, made no difference. I happened to look at the signal strength, and for some reason, the Raspi always picked the AP with the least signal (27/70), dunno why. I pointed it to a different AP, and it's been fine for almost 24hours now. -- Per Jessen, Zürich (16.9°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't know if the Wifi is a must for you, but I've had a Pi3 hanging off my network (cabled) since 2016 and it has been absolutely bulletproof. 5-foot of CAT 5E and 2 RJ-11 cable ends and a crimping tool goes a long way toward eliminating the Wifi problem :p -- David C.

Hehe, yeah I'm sure it does :-) Wifi is a must, without Wifi it would have been too much effort to drag the cables etc. I have one Raspi and three nanopis in locations that are slightly difficult to access, certainly with a cat5. The nanos do also have problems with the wifi, maybe I'll have to check their signal strengths too. -- Per Jessen, Zürich (14.5°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That may be the wrong strategy, it may even be a counterproductive strategy. Last year the wifi from my Thompson router worked just fine but a month or so ago I was having problems. I downloaded (eventually) a signal strength analyser and realised what is going on. YMMV Thanks to the lockdown everyone is at home all days, adults and kids. All using the 'Net, much of it using wifi. This is a condo townhouse estate; houses are close to each other. Most people seem to solve their wifi problem by turning up the signal strength! Crazy, but the strongest signal I get is from over 250 meters away and is 12dB stronger than anything else. Everyone is trying to swamp everyone else ... ... but ... The tool can also analyse by channel and it seems the 'auto' setting starts at channels #1 and stops at maybe #10. Higher channels than that are unoccupied, so i set my router to use #14 and have no problems, even though I'm 60dB weaker than my nearest neighbour.

You get an improvement by using an access point that supports MIMO (3 antennas). It can shape the transmission to give more power in the direction of the receiver. Those other people are possibly using illegal power enhancers.

And of course location the access point helps :-) But since mine is a combined router that has to be within a cable outlet range (and yes I have a long cable from the outlet, but even so) and the switch can cable range of the PCs and printer etc etc ... I don't have the flexibility that some online articles suggest for 'central placement. But my point is that what I have is 'good enough' and worked just fine even with the AP set to 30% output last year. Overpowering is unsociable

That is quite likely. And unsociable as well. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I forgot to mention that it is designed for a flat, not for a house with two or more levels.

Ah. The scanner I have indicates a powerful AP labelled 'BASEMENT'. Looking at distances I suspect that it is one of a couple of APs in that house, never mind that I can access it (I don't know the password though) from more that 80 meters away and I suspect at an elevation of about 12 meters (say 40 feet). There are plenty of articles on the 'Net about how to cut out cardboard shapes and cover them in tin foil to make reflectors for the two antenna that stick up on many routers. My Thompson has internal antennas. *sigh* I saw an article about converting a wifi router with internal antenna to added external ones, drilling and re-wiring. Some time I should open up the Thompson to see if it has the sort of internal connections mentioned in that article. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

On a training course I did, one of the items was making a WiFi antenna out of a Pringles cylinder box - I mean really making and testing one, not reading about it :-D - -- Cheers / Saludos, Carlos E.

Actually, there's one situation where much higher power is legal. Both the 2.4 and 5 GHz bands partially overlap amateur radio bands. On those frequencies, radio amateurs are allowed up to 1 KW. Yep, a thousand watts! That's the same neighbourhood as a microwave oven. Note, this is DC input power. In pulsed service, the peak power levels could be significantly higher Some of the WiFi spectrum is also shared with radar, where high power is also used, though individuals wouldn't be involved with that. So, I could legally run more than enough power to knock out every WiFi device in the vicinity. Under the laws regarding licensed and unlicensed services the WiFi users have to accept such interference, but cannot interfere with the licensed service. https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf01226.html#t1 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Which it is absurd, if you think properly. They probably thought that it was something of little real use, just for geeks, not worth carving out a bit of spectrum solely for them.

No, that's the way things have been done, long before there was WiFi. There are primary, secondary and sometimes tertiary users. This means the primary user has protection from the secondary, but the secondary has none from the primary. WiFi is unlicensed and as such has no protection and cannot interfere with others. As an example, there is a popular band at 7 MHz. This band is or was shared with broadcasters, with amateur radio secondary. So, amateurs were free to use that band, so long as they don't interfere with the broadcasters. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

<offtopic> Really ? I haven't been active as a ham for a long time, but last time, the power rating was specified as ERP, certainly not DC input power. With a class A license in ITU region 1, you also get to use 1kW ERP up to 2 meters (144MHz) and 70 centimeter (432MHz), but only 250W on the microwave bands above that. </offtopic> -- Per Jessen, Zürich (17.9°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

ERP tends to be used for commercial services, which takes antenna gain and feedline loss into consideration. With amateur radio, at least in North America, it's either DC input power or peak envelope power, depending on the signal type. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

James, Do you hold an amateur license? I do and have off and on since high school. I also used to hold a commercial radio license as well (long ago expired). The law specifies the limits as ERP for commercial as well and amateur emissions for exactly the reasons you enumerated... The combinations of antenna gain, line loss etc, to prevent quasi-lawyers form cranking the combination to emit beyond the lawful levels and then pointing the particular parameter that is in spec and claiming to be legal. It's also why amateurs are held fully accountable for violations that exceed ERP. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

In that link I provided, it listed power levels: 10.2 Amateur Radio Operator Certificate with Advanced Qualification The holder of an Amateur Radio Operator Certificate with Advanced Qualification is limited to a maximum transmitting power of: * (a) where expressed as direct-current input power, 1,000 W to the anode or collector circuit of the transmitter stage that supplies radio frequency energy to the antenna; or * (b) where expressed as radio frequency output power measured across an impedance-matched load, o (i) 2,250 W peak envelope power for transmitters that produce any type of single sideband emission, or o (ii) 750 W carrier power for transmitters that produce any other type of emission. I have the advanced licence. So, it's strictly transmitter power that's considered, not antenna gain, feed line loss, etc.. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You get an improvement by using an access point that supports MIMO (3 antennas). It can shape the transmission to give more power in the direction of the receiver.
Well, the two TP-link APs only have two each, and the D-link only one, so that's unlikely I guess :-) They're probably also too old.

The transmission power is the same, but it is aimed or focused in the direction of the other device, which "sees" more power, perhaps compensating for the attenuation of the building. Then there is another possibility which I don't know how to implement: ducts or special cables that pass the signal from floor to floor, passively. It works in one floor as a receiver, crosses the floor via a hole, and transmits it on other floors. I think it looks like a coax cable with the screen removed in parts. It is used on very high rise buildings so that the radios used by emergency personnel can work. - -- Cheers, Carlos E. R.

I guess it might be worth trying when we upgrade, but lack of signal is not really the problem.

You get an improvement by using an access point that supports MIMO (3 antennas). It can shape the transmission to give more power in the direction of the receiver.
Well, the two TP-link APs only have two each, and the D-link only one, so that's unlikely I guess :-) They're probably also too old. I don't need more power anyway, every device is well within the wifi operating range. It's more about the signal being blocked/restricted by e.g. metal doors, steel reinforced concrete etc.
The transmission power is the same, but it is aimed or focused in the direction of the other device, which "sees" more power, perhaps compensating for the attenuation of the building.
I guess it might be worth trying when we upgrade, but lack of signal is not really the problem.
Have you tested yet with the android app?
Then there is another possibility which I don't know how to implement: ducts or special cables that pass the signal from floor to floor, passively.
Yup, we have that - ethernet :-)
No no, it is radio. - -- Cheers, Carlos E. R.

Colours are important :-D On one app, I don't remember which, the graphs were trapezoidal lines, not nice curves.

You can not move around the house with that.
Indeed, and you cannot see the comparative channel occupancy and power distribution. As said earlier, moving around the house takes you into and out of the shadow of material that blocks or reflects signals. The while point of domestic (and to a degree, commercial) wifi is that you CAN move around. You can search out the recipe on your phone/tablet/laptop then carry the device to the kitchen to read as you cook, then to the table and add comments on it after eating. Just an example from my own experience. I'm sure people can suggest many more. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The wifi devices discussed here are not moving - the raspi does have ethernet, but that would mean cat5 which isn't practical. The nanopi's only have wifi.

How would they manage that? The only way that would be even possible would be to use VLANs and multiple SSIDs. Also, consumer grade gear tends to support only a few SSIDs, assuming it does it at all.

(no problem to drill those holes here (Spain), if both neighbours agree (better in writing). But there is no need to do that in relatively modern buildings, as there are already ducts that we could wire in that manner).

Technically, it would be perfectly possible for a building to share an internet connection with a bunch of neighbours, sharing the cost and the infra. You would need one VLAN per home, I think, isolating each home from others. The problem would be that the Telco companies hate this (and their local laws protecting them). You can not share a home connection, you would have to hire some other type of connection, if they have it. In fact, there are villages in Spain where all neighbours share a single WiFi setup done by the council, gratis (ah, socialism! ;-p). They do this because the Telcos refuse to do home connections or they ask impossible prices. Possibly, they don't even have fixed phones at the houses. Years ago, someone from Russia commented in this mail list that they had an Ethernet connection network spanning entire blocks on the city. A big intranet, free.

First off, WiFi isn't known for long distances. It doesn't take much to block it. In fact a friend of mine can't get a signal from one room to the next, because of the wall construction. Reinforced concrete tends to block the signal. Also, in many areas, only utilities are allowed to cross properly lines, roads etc. What may be possible from a strictly technical perspective, might not be from a practical or legal one. As I mentioned, I live in a condo. There are 48 units in my building. That means there will be a lot of people sharing the signal. Depending on location, some may get better signal than others. Also, I'm on one ISP, my next door neighbour might be on another, the next on yet another. Whose ISP do we go with? BTW, I had a bit of an interesting encounter this morning. One of my neighbours said someone had been putting notices on people's door, telling them to turn off their WiFi, for whatever wacko reason. I then used a cell phone app to show her all the WiFi signals I could receive, while standing in front of the building. There were dozens.

One ISP for the building, that's all, with a commercial contract, not a home contract. Similar to what an hotel does. Some engineer would have to do the planning and setup several APs in the common corridors, with proper frequency and pattern distribution (single SSID). More work for us chaps ;-)

That friend I mentioned, who can't get WiFi to pass between rooms, lives in a condo where they have that setup. He's limited to 10 Mb download, IIRC. I get 75 (actually low 90s) and can get a Gb if I want.
Some engineer would have to do the planning and setup several APs in the common corridors, with proper frequency and pattern distribution (single SSID). More work for us chaps ;-)
I frequently call my ISP to see what I can do to improve my package. In fact I did that on Monday. One of the changes I got was I went from 500 GB limit to unlimited and my cell phone went from 7 GB to 10. I do this completely independent of what my neighbours do. Also, if there were one company for the building, I might wind up on one which I have vowed to never do business with again (long story that involved a complaint to the government about them) and they're not even allowed to contact me again.
BTW, I had a bit of an interesting encounter this morning. One of my neighbours said someone had been putting notices on people's door, telling them to turn off their WiFi, for whatever wacko reason.
:-o
(maybe blaming wifi for the virus?)
I then used a cell phone app to show her all the WiFi signals I could receive, while standing in front of the building. There were dozens. I also mentioned there were some point to point WiFi links connecting the buildings, for the security cameras.
Of course.

I know.
As I mentioned, I live in a condo. There are 48 units in my building. That means there will be a lot of people sharing the signal. Depending on location, some may get better signal than others.

In such a place, a communal setup would not be practical, unless they also created one access point per home.

Sure. But it would not be you who would hold the contract, but the building owner (condo) or the association of owners (Spain). And of course, would not include the mobile, probably not the cable TV. Only internet. Like an hotel. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

Actually, both the company I have and the one I don't want to do any business with provide Internet, TV, phone and cell phone. The Internet, TV and phone are often bundled, with the cell phone a separate service. There are several apartment or condo buildings around here, where one company has exclusive rights for cabled connections. Fortunately, mine was built before any company offered everything. Back then one company (the one I deal with) offered cable TV and another (the one I refuse to deal with) provided phone. Back in those days, the ISPs were dial up. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Can be done with a single communal provider and a controlled AP per home (theoretically). The law is another thing. This is in the case that the walls block the transmissions, so you need more APs. But designed and controlled by an engineer, not by the people living there, to minimize interference.

The situation in Spain is different: by law, apartment buildings must give access to any ISP that wants it. Well, the law is more detailed, but basically any home has several choices. During construction, ducts must be placed to simplify this. It also applies to existing buildings, within the limitations of the building. The purpose of the law is to facilitate competition between providers. For a communal setup the owner would have to do some type of business contract, and those can be internet only, I understand. Anyway, we do not have "condos", we have apartment buildings with, in theory, one full owner per apartment, and an owner association for the communal parts, like the stairs. As an example, you can buy two apartments and connect them inside with doors, even internal stairs. But we are going offtopic ;-) -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

The problem would be that the Telco companies hate this (and their local laws protecting them). You can not share a home connection, you would have to hire some other type of connection, if they have it.
I think that is the least of the issues. Many countries have telecommunications legislation that simply forbid the sharing of a connection. For instance, it is a problem for law enforcement: "someone did illegal downloads. Who was it - household A or household B?"
In fact, there are villages in Spain where all neighbours share a single WiFi setup done by the council, gratis (ah, socialism! ;-p). They do this because the Telcos refuse to do home connections or they ask impossible prices. Possibly, they don't even have fixed phones at the houses.

In Spain people have won in court demanding the accuser to show proof of what person did the download. It is not enough to point at the router.

It is simply not economical for the telco to provide some phones at a village in the middle of nowhere. The council, on the other hand, has the oomph to buy one large enough connection at whatever cost, then share it. There were legal problems initially, but I think they found a way. There is a fund from the EU for it. <https://cincodias.elpais.com/cincodias/2019/09/18/companias/1568818711_540735.html> Name "WiFi4EU". <https://wifi4eu.ec.europa.eu/#/home> No wikipedia article :-? -- Cheers / Saludos, Carlos E.

I know - that is why it would have been important to have a clause that obligated the national incumbent telco to provide a minimum of connectivity, everywhere.

I don't know if the Wifi is a must for you, but I've had a Pi3 hanging off my network (cabled) since 2016 and it has been absolutely bulletproof. 5-foot of CAT 5E and 2 RJ-11 cable ends and a crimping tool goes a long way toward eliminating the Wifi problem :p

Actually, he might mean RJ25, which is the 6 wire version of the phone jack. RJ11 was only 2 wires. Way back in the dark ages, what eventually became 10baseT Ethernet was called StarLAN and intended to run over existing CAT 3 phone wiring. That wiring would often be 3 pairs to an RJ25 jack, with the middle pair used for the phone and the other 2 for the LAN. https://en.wikipedia.org/wiki/StarLAN https://en.wikipedia.org/wiki/Modular_connector#6P6C -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Good luck plugging that in to the raspi's RJ-45 or finding a hub with an RJ-25 connector for that matter :) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The point is, the raspi has a soldered-in RJ-45 connector. You have to connect to that, or else solder in some other connector :( It doesn't matter what you crimp on to the cables - they have to terminate somewhere! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yep, 6 pin connector on one end and 8 pin on the other. 2 & 3 pair CAT 3 used to be common. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I must be dumb. What does the 6-pin connect to? Routers have RJ-45s too. What is the point of a 6-pin connector anywhere in the circuit? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The existing phone wiring. Office phone jacks were normally connected to 3 pair cable, usually terminated on 6 wire connectors. I have the same thing in my home. So, offices would be full of 3 pair cable, running back to a wiring closet and terminating on (usually) BIX strips. Since most phones used only a single pair, the other 2 pairs were available for a LAN. This is what StarLAN was designed to work over. If you're in a reasonably modern (~40 years) home, take a look behind your phone jack. You will likely see 3 pair CAT 3 cable, connecting to a RJ25 connector. Prior to that, typically 4 wire red/green/black/yellow cable was used without jacks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
