Description jcallen 2010-04-05 19:30:39 UTC
In 2.6.32 (and earlier), I was able to use the rt2500usb driver with my D-Link DWL-G122 wireless NIC (ID 2001:3c00 "D-Link Corp. [hex] DWL-G122 802.11g rev. B1 [ralink]").  Now, with 2.6.34-rc3-00191-gdb217de, once I get an IP address via dhcpcd, it immediately looses the connection, with the following message repeated in the syslog:

phy0 -> rt2500usb_set_device_state: Error - Device failed to enter state 3 (-16).

Any chance I could talk you into a git bisect? :-)
Comment 2 Ivo van Doorn 2010-04-05 20:23:21 UTC
Instead try:

iwconfig wlan0 power off

to disable power saving.

I haven't gotten a chance to do so yet, but I am able to do a bisect, if needed :)

I've tried that, and it seems to be working now
Comment 4 Ivo van Doorn 2010-04-05 21:32:55 UTC
ok, no bisect needed then. Patches to fix this issue are on the way. :)

John, the patches which fix this are part of GertJans patch series:
