Wireless problem with usb dongle (ralink rt73)

Hi, some days ago my wireless connection stopped working. Before it worked beautifully, then it suddenly stopped one morning without changing anything in the network configuration files (I use rc.conf with WEP). I think I updated the kernel to 2.6.34 the night before but I'm not sure.
Here's my lsusb:

Bus 002 Device 003: ID 07d1:3c03 D-Link System DWL-G122 802.11g Adapter(rev.C1) [ralink rt73]

Here's lsmod:

$ lsmod | grep rt
rt73usb                20705  0 
rt2x00usb               6576  1 rt73usb
rt2x00lib              21985  2 rt73usb,rt2x00usb

rtc_lib                 1486  1 rtc_core

And this is what I get from everything.log:

$ cat /var/log/everything.log | tail

Aug  9 18:49:53 maldiluna dhcpcd[2972]: wlan0: broadcasting for a lease
Aug  9 18:50:23 maldiluna dhcpcd[2972]: timed out

It seems a timeout problem, but I tried increasing it up  to 2 minutes without success. I have a laptop with an Intel wireless chipset and it connects without any problem, so I think the access point is working and that there might be a driver issue.
Thanks for the help.

I have found this similar discussion:

https://bbs.archlinux.org/viewtopic.php?id=96183

The problem they are reporting seems similar to mine. But my dongle worked fine when that discussion was opened, it stopped one week ago...

I resolved the problem: as I suspected it is a kernel issue. Downgrading to kernel26-2.6.33.4-1 and kernel26-headers-2.6.33.4-1 the problem disappeared. Since 2.6.35 is out and coming soon to the repos, should I file a bug?

With kernel 2.6.35 from [testing] everything works fine, so I think the problem is limited to 2.6.34. Hopefully it will not appear again in the future...

Just my 2 cents. If you can, switch to WPA2. WEP can be broken in under an hour.

Re: Wireless problem with usb dongle (ralink rt73)

Sadly for me, I have to revive this thread. Actually, kernel 2.6.35 doesn't solve the problem: it works only the first time I boot it after the installation. At successive boots the network won't start. The only way to make it work is to downgrade to 2.6.33, which works fine; if I then upgrade again to 2.6.35 it works only at first boot.
Does anyone have a similar issue / know what's going on / know what to look at? Thanks
