I have a fedora 8 x86_64 system with an ralink 61 chip set. The chip set works ok from a power on. It associates correctly
with the wep key and the ssid. If I do an ifdown wlan0 and the an ifup wlan0, the card will never again associate with
the access point even when I set the ap via iwconfig.
# modinfo rt61pci
description Ralink RT61 PCI & PCMCIA Wireless LAN driver.
vermagic 22.214.171.124-49.fc8 SMP mod_unload
Any ideas? It seems like I need to reset the card, but here sees to be now way to do this
You are using rt2x00 (which is why I moved this thread), keep in mind it is still in development and fedora may not be shipping the latest version.
As a workaround, you could try to remove the kernel module, then insert it back
[code29adf9j9]modprobe -r rt61pci
Fedora is shipping the latest driver version (as far as I know).
Does scanning work after you ifdown & ifupped the device?
No scanning does not work after an ifconfig wlan0 down and an ifconfig wlan0 up
or ifdown wlan0 and ifup wlan0
There seems to be no private ioctls either. The card radio seems to be off
or needs a hardware reset.

I did try to remove and loaded kernel module but that did not help.

I solved the problem in a very different manner.
I moved the channel from 6 to 8 where there was no interference from other
In fact the presences of an other wireless card on my channel reduces the
reported speed of the interface to 1 mb
As a Ham radio operator, I wonder how good the radio and its firmware is.
Do we need new firmware?
I suspect the radio firmware is not correct
Ralink has not updated the firmware in ages, and have indicated it won't be updated soon either.
You can just assume the firmware is correct.
Ok, what data could I collect to find the problem of interference?
I would like this problem to be fixed, and I am pretty sure it is the radio code,
because the link speed varies from 1 to 54 mega bits/second constantly.
This would have to be reported by the radio.
What would be interesting to know is what the difference in register contents is from before and after the ifdown & ifup cycle.
Check the tools found here http//kernel.org/pub/linux/kernel/people/ivd/tools/
for methods to dumping and comparing the register contents.
I will do this tonight when I get home and post the results
