NetworkManager issues in Debian Sid
I installed Debian Sid on my new laptop, which uses a Broadcom based wifi card (big mistake on my part for not checking to see if it was compatible before buying). Getting the wireless to work was a big enough headache, the native bcm43xx driver didn't seem to support my card, so I went with ndiswrapper instead. ndiswrapper seemed to work after some fiddling around with different driver versions and realizing that I needed a 64-bit driver, and I then installed NetworkManager and knetworkmanager to manager the wifi connections. Everything seemed to be working fine, I was able to connect to my home wifi network effortlessly, as well as the wireless network in the computer lab at school. My problem now is that I can't get a reliable connection to my campus wireless connection, I can connect for about 5 minutes before the connection dies out and won't let me reconnect.
This problem only occurs using NetworkManager, when I set the ESSID manually using iwconfig and then use ifup to bring the interface up, I get a connection fairly easily. I would like to make this automatic using NetworkManager, but it doesn't seem to want to work. I also noticed something weird in the output of iwconfig:
I don't know what Tx excessive retries or Invalid misc are, but they don't sound good, and there are a lot of them. Anyone know what that means, or know a remedy to my problem?
lo no wireless extensions.
eth1 no wireless extensions.
