losing wireless connection
 
I'm on holiday and I've got wireless Internet access here.
When I boot my notebook, set the parameters of the AP and execute 'sudo dhclient eth1'
(Ubuntu Dapper Drake) I get:

Code:

Listening on LPF/eth1/00:14:a4:33:df:52
Sending on  LPF/eth1/00:14:a4:33:df:52
Sending on  Socket/fallback
DHCPREQUEST on eth1 to 255.255.255.255 port 67
DHCPACK from 82.250.106.254
bound to 82.250.106.137 -- renewal in 59 seconds.

After some time (doesn't always seem the same), connection is lost and
ifconfig shows I've got no IP anymore. Executing dhclient again:

Code:

Listening on LPF/eth1/00:14:a4:33:df:52
Sending on  LPF/eth1/00:14:a4:33:df:52
Sending on  Socket/fallback
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 9
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 9
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 20
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 5
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

Rebooting seems to help, but that's no solution. Anyone knows what might be wrong here?

What card/driver are you using?

Code:

$ lspci | grep Broadcom
0000:00:0b.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)

I'm using the bcm43xx driver included in the 2.6.15-25-386 kernel. But I haven't had this problem on my wireless network at home.

The same notebook with this same configuration works fine at home but you keep losing connection there... Is anyone else having the same problem. I had a wierd problem like that once. Then I noticed every time I lost connection someone was using my wireless phone. Turns out the phone was the same frequency the router was using. I went into the router config and put it on a different channel and havent had a problem since.

Hmm, there is no regular phone here. But there are about 8 people here, all carrying cell phones. But I believe there have been calls today, without problems. In fact, I haven't had any troubles with the wireless connection during the last 2 days. Very strange.

Yea it wouldnt be a cell phone, just a land line wireless phone
