[opensuse] Wireless setup [OT]
Sorry for the off-topic post, but I don't know where to ask, so any pointers are welcome. At home I'm trying to set up a wireless accesspoint (connected to a Suse sever, that's why I ask here ;-) ). If the accesspoint is placed inside the house it's impossible to get access to it. I tried with two different products (Linksys and D-Link). Those accesspoints do work fine elsewhere, even in my gagage, which is a different building than my home, max. 20m away, but from inside my home I can't connect. I tried all channels, with no luck. So, has anyone of you some hints what to try next to get connected ? P.S. as far as I know there are no other transmitters in that band (2.4GHz ?) at home. -- Met vriendelijke groeten, Koenraad Lelong R&D Manager ACE electronics n.v. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

A lot of them are in that band and will interfere.

Hey,
So, has anyone of you some hints what to try next to get connected ? P.S. as far as I know there are no other transmitters in that band (2.4GHz ?) at home. Do you have a cordless phone?

Yes, DECT should use the band from 1880 MHz to 1900 MHz, but ETSI allows 2400–2480 MHz which can cause trouble. If your wlan router and your wlan cards allows you to choose channel 14 (normally available in Japan) then you have a good chance that they are not overlapping. I'm not sure if this helps, but you can also adjust the burst-rate at the wlan-router. Furthermore it helps to look for other radio-emitting (phone, microwave, ham radio) devices that stand closely to each other (to the wlan router). Try to place them at least 12,5cm away from each other. A next good guess would be to look what objects are standing close to the wlan router, because of reflection, refraction and interference it is possible that the transmission waves are razed.

Thanks for those suggestions, but besides some cell-phones (not near laptor or accesspoint) we don't have any wireless (radio) devices, and the microwave oven is meters away and inactive at most of the times of my tests. I'll look at the burst rate and give it a try. I tried at least five different locations in the house but except for one these were on or in open wooden closets, next to a wall. The other one was on the table max. 1 meter away from my laptop. I'll try on a different table farther away. -- Met vriendelijke groeten, Koenraad Lelong R&D Manager ACE electronics n.v. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

How high is your router/access point located? In our computer room we had the router on a cabinet up right at the ceiling. Getting a connection on our laptop on a TV tray right below it was nearly impossible. Move to the other room and it connected just fine. Lowered the router and end of problem. Just a thought. -- (o:]>*HUGGLES*<[:o) Billie Walsh The three best words in the English Language: "I LOVE YOU" Pass them on! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Every now and then, I have read a few of the responses on this discussion. I just have a few comments. You definitely do not want two wireless devices communicating on the same channel too close together. Even nearby channels can cause the transmitter to overload the receiver circuit. While the symptom is data distortion, we are talking about a potential damage to the receiver circuit. Good receivers would simply shunt the signal to prevent damage. With low power devices, antennas become extremely important. At the frequency of wireless devices, polarization can make a several db difference in signal strength. In other words, all antennas should be horizontal or vertical. Vertical orientation usually give the best horizontal coverage, but will have blind spots of the ends of the antenna. Just think of a doughnut being placed over the antenna. You can then easily visualize the radiation pattern. I personally miss the PCMCIA cards that allowed the antenna to be vertically polarized. To overcome this shortcoming, I wrap the cardboard core of a toilet paper role with tinfoil, and set stand it next to the wifi antenna. It does give a small signal boost, because the tube is almost a perfect 1/4 wave length antenna. If I really want distance, I use a wireless card that has an external antenna. There are some really cool external antennas that provide significant signal gain. Just in case you are wondering, I am an amateur radio operator. Playing with radio signals is second nature.

Not a whole lot of breading boarding, no wires and only two components. Take one cardboard toilet paper tube (sans toilet paper), and wrap with aluminum foil. Stand tube vertically next to the PCMCIA card. The tube will give a small signal boost by acting as a collector. If you want some interesting stares, try asking for the components from a hotel staff.

My next step would be to place my wireless enabled and positvely tested!!!, working notebook just an inch away from the access point and make this setting work. Then slowly, but surely increase the distance and carefully note the point in time, where the connection fails. Lastly, I would draw my conclusions and proceed from there. regards Eberhard -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Actually, I've had a bit of trouble connecting when just an inch away. Signal too strong and swamps the laptop wireless. Moving two meters away always seems to work better. I agree that you should always test with a clear line of site. ----Other posters mentioned cell phones. I often sit with a laptop on my lap and cell phone beside it or in my pocket, and have never had any problem. Even when talking on the phone. -- _____________________________________ John Andersen

I found that in my house I have three peaks that are more or less blocking all channels except for channel 1 and maybe 13 (for 802.11g anyway). Anyone interested in a picture can have one ;-). I don't know where those peaks come from, maybe the detectors of the alarm system. I set my AP to channel 1, and WinXP seems not to have a problem connecting. Suse10.1 on the same laptop (dual boot) can't connect : it times out after 60 seconds, as seen in Networkmanagers' logfile. Is
