Wireless connection drops out after random interval

[dave_deu]

I have a DWL-G520+ network card that is supported by the MadWifi drivers. I have compiled the "acx" module against my current kernel and the network sometimes works.

There are 2 problems.

1) Sometimes (4/5 times) the network doesn't come up on boot up.
2) When the network does go up at boot time, it drops out 5-20 minutes later (and never comes back up).

Here are some relevant details.

If the network is up, then drops out, I do this:

Code: Select all

/etc/init.d/net.wlan0 restart

and I get this:

Code: Select all

 *   Couldn't associate with any access points on wlan0
 *   Failed to configure wireless for wlan0        

If I then try to use dhclient to get an answer (with "dhclient wlan0" - dhcp doesn't work and also gives no feedback) I get this:

Code: Select all

Here is a listing of /etc/conf.d/net:

It all used to work fine! Any ideas?

Thanks,
Dave.

Just wondering is there many routers sharing the same channel? Does changing the channel help?

[dave_deu]

I changed the channel and so far so good. I'll post back if it stops working again.

Thanks!
