Subject: [gentoo-user] wireless dropping connections
Date: Tue, 30 Oct 2012 11:33:42
1 I'm using wicd- and a NetGear DGN2200M v2 wireless AP
2 (802.11n)
4 Several times a day, this thing just drops wireless. I doubt it's my
5 laptop as other devices in the house also get affected. When this
6 happens I usually manually reconnect using wicd, it can do this
7 automatically but there's a long timeout first before it realizes the
8 connection was dropped.
10 The router logs have very little in them, all I see is my laptop asking
11 for and getting a new IP. Laptop logs show this:
13 Oct 30 13:10:45 khamul dhcpcd[24141]: wlan0: carrier lost
14 Oct 30 13:10:45 khamul kernel: [229075.169304] cfg80211: Calling CRDA
15 to update world regulatory domain Oct 30 13:10:45 khamul kernel:
16 [229075.214909] cfg80211: World regulatory domain updated: Oct 30
17 13:10:45 khamul kernel: [229075.214911] cfg80211: (start_freq -
18 end_freq @ bandwidth), (max_antenna_gain, max_eirp) Oct 30 13:10:45
19 khamul kernel: [229075.214913] cfg80211: (2402000 KHz
20 - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
22 followed by the usual verbose junk of reconnection logs.
24 I wouldn't even know where to start debugging this. The only unusual
25 part of the setup is I don't use the router's dhcp server, that is done
26 with dhcp-4.2.4_p2 on a separate wired Gentoo server.
28 Anyone have a logical series of debug steps I can apply?
