Topic: WiFi dies (BCM4312) [SOLVED]

Hi!

This is annoying, and something I would appreciate help with. As the title says: my WiFi ”dies” infrequently when I am not at the computer. When I come back I have to disable WiFi - and then activate it with Network Manager.

Here are some specs:
LSPCI:

0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)

IWCONFIG:

wlan0     IEEE 802.11bg  ESSID:"WEIGHT"  
          Mode:Managed  Frequency:2.432 GHz  Access Point: 6C:F0:49:AD:ED:62   
          Bit Rate=36 Mb/s   Tx-Power=27 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=36/70  Signal level=-74 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

IFCONFIG:

wlan0     Link encap:Ethernet  HWaddr 00:1c:26:49:59:5a  
          inet addr:192.168.1.9  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::21c:26ff:fe49:595a/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2078127 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2267173 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1592374708 (1.4 GiB)  TX bytes:1939635879 (1.8 GiB)

I am at a loss here sadly. Oh, and this worked with Ubuntu 10.10, so I'm sure there is a way around this somehow - I just don't know what/how.

Thanks for reading,

HMW

Re: WiFi dies (BCM4312) [SOLVED]

for clarification: 'when i am not at the computer', i take it this means that the system goes into hibernate? or does this event take place as an effect of you being not physically present behind the computer screen? in other words, what triggers this?

bash :: @script :: system :: fclean

No. Not hibernate. Only screensaver (black screen). All i have to do is touch a key, and I'm back, no need to log in, no locked screen, but WiFi is down!

Thanks for replying!

Re: WiFi dies (BCM4312) [SOLVED]

I tried the other firmware (firmware-b43-lpphy-installer), but that was a no-go. No connection at all.

So, to sum things up:
1. WiFi works.
2. But if I leave the computer unattended for about ten minutes, it ”dies”.
3. I then have to deactivate WiFi, and activate it again with NM to get things going.

?

Best,

HMW

Ok, maybe this will work: http://wiki.debian.org/wl#Squeeze

I'll give it a try, and then it's good night!

Edit: Ok. Went through the steps in the link above. I have a working WiFi now (with what seems to be a slightly better signal - but I might be dreaming). Now... we wait!

Good morning!

It seems as if this indeed was necessary. It is a little hard to be sure, but now I have left the PC alone for about 30 minutes, and WiFi is still alive and well.

I'll wait a little before marking this thread as SOLVED though, just to make sure.

I followed this: http://crunchbanglinux.org/forums/post/146327/#p146327 link in order to get where I am now, so a big thank you to dubois for the info!

Best,

HMW

Edit: Marked as solved. Adding some Google-friendly stuff below.

Re: WiFi dies (BCM4312) [SOLVED]

It's an actiontec router (Verizon FiOS router) with wep (nintendo ds lite doesn't play well with others, and we're far enough away from neighbors to not have to worry)

I'll take a look at that, though.

EDIT: OH GOD, WRONG THREAD! D:
