I'm completely and utterly frustrated with my wireless connection... I've tried several different network adapters and several different machines, but the result is about the same... my connection is great for a few seconds and then seems to stop working. Everything indicates that the connection is still up and running, but not even a ping to the router gets through.
To simplify things, I'll just talk about the one network adapter and machine...
I'm using Ubuntu 8.04 with a Broadcomm "BCM94311MCG wlan mini-PCI" adapter using the "ndiswrapper+bcmwl5" driver.
When I run the wpa_supplicant, it seems to indicate that it's connected properly, but it never returns to the terminal to allow typing the rest of the commands (it's supposed to, right??). It ends with "EAPOL: startWhen --> 0". I then type the rest of the commands in another window (while wpa_supplicant is still running) and everything seems to work correctly. However, after about 5 seconds no traffic gets through.
After running the dhclient, I tried pinging the router until it stopped working... It started out with pings around 30-200ms, then jumped to 2000-10,000 ms pings, then dropped to 1-3ms pings. Then, it paused for a long while and started reporting "ping: sendmsg: No buffer space available". I stopped it and then restarted it and started getting:
Code:
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

From 192.168.0.3 icmp_seq=10 Destination Host Unreachable
From 192.168.0.3 icmp_seq=13 Destination Host Unreachable
I've used this network adapter with this router before in Ubuntu 8.04 and had no trouble. The only change is that I moved it from one city to another. I'd chalk it up to radio interference, but it all works fine in Vista, XP, and Win2000.
