Hi,
I've got a Linksys WUSB54GC WLAN USB interface (Ralink chipset) and I'm running Debian GNU/Linux 6.0. The LED very often randomly blinks although there is no traffic in the network. I checked this with Wireshark. Sometimes, but rarely, the LED stops blinking.

The issue is present in Ubuntu and Fedora too. It was not present in Debian Lenny with Linux 2.6.28. I checked an old live cd with ubuntu 8.10 with kernel 2.6.27 and it was also OK. So I guess that's an issue with Linux kernel and its wireless driver or firmware.

Has anybody observed a similar thing? Does anybody know how to help this annoying blinking?
Thanks.
