I've gone from using CAT5 to 802.11g for my laptop's network connectivity while I'm at home. Unfortunately, since I've done so, my connection drops from time to time, and I usually don't notice for a while. The period between drops does not seem to be constant, however, as I lost my connection at some point yesterday without noticing, but when I did notice I reestablished contact, then lost my connection again a few minutes later. The connection has not dropped again since then, however.
I'm using an Intel 2200BG adapter (Centrino chipset) with WPA encryption
and the wpa_supplicant connection manager. My wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
# netwerk
network={
ssid="netwerk"
psk="ssdpbwqaougj6hr9"
}
(PSK changed to protect the guilty)
When the connection drops, I get the following in /var/log/messages:
Jun 9 23:14:21 hostname kernel: iwi0: link state changed to DOWN
Jun 9 23:14:28 hostname kernel: iwi0: scan stuck
Jun 9 23:14:34 hostname kernel: iwi0: could not allocate firmware DMA
memory
(watch the line wrap)
In case it isn't obvious, "iwi0" is my wireless interface.
All /va/log/dmesg seems to show is this:
iwi0: link state changed to DOWN
iwi0: scan stuck
Any ideas on where to go from here would be appreciated. Is this a
driver bug, or am I doing something wrong? Another (effectively
identical) laptop running Debian does not have this problem.
