[opensuse] troubling line quality results
Since some days I had problems to connect with the internet. After checking the net speed and the line quality with the pingtest of Ookla I found that the computer I always use had a line quality between D and F. According to the test side barely usable for a lot of programms. (computer C) Did run the test also on a reserve set with a fully updated Tumbleweed and much to my surprise with that machine I have a very good line quality A or B. (computer A) Having a notebook with (not fully updated) Tumbleweed gave me a surprise C line quality. (computer B) All computers are connected to the same router. Cable length same. With every repeat of the ping test the results are same. All connectors are clean and according to my logic, the results of all three computers should be same. Could some body come up with the reason or reasons for this troubling result. Details of the computers: A) Desktop Computer 1, Line quality A or B, has a dual core Intel Pentium D, CPU 3,40 GHz, Network card PRO/100 VE Network connection (eth0) B) Notebook Computer , Line quality C, dual core ATOM CPU N270, 1,6 GHZ, Network card Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controler (enp3s0) C) Desktop Computer, line quality D, E, F, Intel Pentium 4 CPU 1,80 GHZ Network card RTL-8139/8139C/8139C+ (enp1s5) Opensuse Tumbleweed was freshly setup on A and B. Computer C was updated from 12.3. What wonders me is why computer A is still using the old eth0 and both computers with worse line quality are using the new name setting.

Hi James, Let me relate this to you and you can then make up your own mind. But to begin, you did not mention if you conducted your tests all at the same time or were they spread over a period of, say, days or even hours. I have ADSL2+ and my modem/router is some 5-6 kms away (measured by wire-length) from the 'exchange which, therefore, cannot possibly provide me with the theoretical max. 24Mbps broadband speed. For years I was only getting nothing better than ~2X the dial-up speed and even though I had the phone/modem-router checked and replaced, that's the speed I got. And, of course, if the phone line was congested or the links from my ISP to where I was pointing my Firefox at were overloaded or were having one of those famous "outages" then my thruput dropped dramatically. Now comes the revelation :-) . A couple of years ago there was a bad noise problem on the phone line so bad that one couldn't even hold a conversation over the phone. You can imagine what effect this had on the ADSL2+ connection! I checked ALL of my gear in the house - the phones, the modem, the filters on the phone line for the ADSL2+ connection - and they were all perfect. I had to do this because our telco, Telstra, charges you $$$$ for being called out and only to find that the fault is caused by YOUR equipment and not theirs. And this is when a miracle happened! A Testra contractor (everything is now outsourced dontcha know) arrived; a young Czech. or a Hungarian, don't know which and didn't ask, and not one of the "local lads" and he spent some time in getting the phone line fixed. And you know what? He fixed the line so that now it is capable of getting the theoretical thruput for ADSL2+ for my distance from the exchange, and then just a tad more! All the other "local lads" sent out to fix OTHER PEOPLE's problems, living in the area and connected to this group of phone lines, in the past were grabbing and swapping over MY phone line to get those other people out of trouble and leaving me with crap. So this is part one of the story. The other is that a (?)couple of days ago my thruput dropped down to ~7BYTES/s when I went "surfing" to the rest of the world. I think that it was yesterday that I read that the BT had an outage for which it apologised to all and sundry. In other words, "S*** happens" and the speed can vary from day to day, from hour to hour, from minute to minute.

Perhaps in some cases but not in all. I needed 6 phones in the house and there were not enough paired linest to cater for this and the telco installed 1/2 kilometre of new wiring to be able to give me those 6 phone lines. So, in terms of how old these 1/2 km of lines are, they are 'brand new' according to the telco (copper wires deteriorate by developing microscopic fractures in the copper but anything less than 30 years old is considered "new".) Since that time when the lines were installed I lost the need for all but one phone and it is with these lines that the "local boys" have been "playing around with" to give me crap thruput - until the last "new Australian" techo.
in France such default are repaired for free (if you manage to make the tech come ;-()
As I said, here one does not pay for any 'repairs' if the fault is not caused by anything within your house and between the house and the telegraph pole (which happens to sit in the corner of our backyard). And with the progress of the modern society and, of course, the privatisation of the telco some years ago, it now may take some 10 days to get an outsourced techo to come out and repair a problem whereas before, when the telco was still publicly owned, and not making huge profits for the private sector yobs, getting a fault repaired would take only a day, or 2 at the very latest.

Hi Basil, Your experience with private versus public service response is certainly counter to ours on this side of the Pacific. How does/did your government manage to do it? Competition has been proven to provide the best service experience. When has government ever been "competitive"? BTW, I called our local cable company (Cox Communications) yesterday to arrange for an increase in our Internet bandwidth. For some reason they require an on-site visit by a technician. They gave me an option of 10 to 12, 12 to 2 or 2 to 4 PM. I chose the 10-12 option. The tech called at 9:15 to ask if he could come early. He did and we now have greater bandwidth and a higher monthly cap. Is your "privatized telco" really privately owned, or is your government the monopoly telco provider and contracts with a private company to provide on-site service? If so, that just extends government ineptitude through a private conduit.

I guess you didn't bother to read the article I posted several days ago, Lew, which was: http://www.bbc.co.uk/news/magazine-24528383

Re the above para, a quote from Wikipedia which describes perfectly what Telstra is (and you can also check it out on the Sydney Stock Exchange site): "Telstra Corporation Limited (known as Telstra) is Australia's largest telecommunications and media company which builds and operates telecommunications networks and markets voice, mobile, internet access, pay television and other entertainment products and services. "Telstra has a long history in Australia, originating together with Australia Post as a government department, the Postmaster-General's Department. Telstra is now fully privatised and has been undergoing a change program to become more "sales and marketing led" under its current CEO, David Thodey."

Additional info. Did the tests all close after each other. Problem, each computer has its own range of line quality. Line is same for all three apart from the piece of cable that connects the computer to the router. Is the difference due to the CPU speed, network card or what? That my connection to the outside world is below standard is something I have to live with. As a matter of fact, I just twisted the wires outside of my garden on the telkom pole. Wires were relatively loose and it rains regularly.. For now it works but the rest of the telephone line to the closest server (some 9 km)is in the same state. cannot check all loose connections and twist them. -- Linux User 183145 using KDE4 and LXDE on a Pentium IV , powered by openSUSE 13.1 (i586) Kernel: 3.15.1-35.g3289da4-default KDE Development Platform: 4.13.2 16:10pm up 0:28, 3 users, load average: 0.54, 0.39, 0.36 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ookla is crap. It relies on so much java and java script and Flash that its results are horribly biased by the processor speed. Avoid it, and find another simpler speed test site. Maybe http://www.speedguide.net/speedtest/ or something. That said, you can have different results on different machines based on the NIC in that machine. So check that each nic negotiated the same connection with your router, sometimes various nics will not reliably get a duplex connection. Other than that, and the twisting of the aforementioned wires, if all your computers are on the same router, then any difference must be inside your house, and ratty cables, difference in ports (try swapping ports on the router), or link speed might have an effect. But you have to get rid of things that are processor speed dependent, because nothing in a speed test should burden your processor. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
