[opensuse] wifi 802.11n on 11.3
Hi, I have no real idea how to diagnose this issue so trying here if people have similar experience or ideas what to check/do. I used to have a 54Mb/s access point with a client with 802.11n capabilities (openSUSE 11.3, driver iwlagn). No issues at all using that wifi connection. Since a few weeks I've replaced the access point with a modern one also with 802.11n support. The client speeds up to 300Mb/s as I can with iwconfig or nm-applet. But as soon as I transmit data (just terminal characters so not much) I get a collapse in bandwith (iwconfig goes down to 1Mb/s). This is highly annoying in SSH sessions when you get some characters over the "wire" and then get a pause where nothing gets through for like 3-5 seconds. That even happens with Link Quality=66/70 like quality which I would consider still good. I'm no expert but that doesn't seem to be a connection issue to me. My wireless network also is the only one here so there shouldn't be much noise. Any ideas or hints?

Any related messages in the output of dmesg or in /var/log/messages?

Some combinations of wireless access points and adapters just do not work very well. So, reducing the general performance of the link might help: 1. If you use the 5GHz band, try 2.4GHz instead. 2. If you use the iwlagn driver, try to disable 802.11n by changing the '0' to '1' in /etc/modprobe.d/50-iwagn.conf: options iwlagn 11n_disable=1 ^ Gruß Jan -- A bachelor is a selfish, undeserving guy who has cheated some woman out of a divorce. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
