Comment 163 for bug 190515

Hm, seems my RT2560 based card is now also affected by this issue, although I actually didn't notice until now.. (well, recently, I exchanged my modem router, but that should not be an issue - a netbook with an Intel wireless device runs at full 54M bandwidth all the time, while my RT2x00 card slows down at the same time).

The card's power management is off by default on my system (by rc.local), yet it seems the card slows down from time to time to rates around 1400mbit/s. At first I thought this had something to do with pptp being enabled over the wireless network, but the problem persists when I disconnect from VPN. After shutting down the wireless connection via NetworkManager, and bringing it up again, bandwidth returns back to normal.

iwconfig permanently reports 54M, signal strength is 80% most of the time. Is there a safe way to undoubtedly tell the bandwidth reduction I am experiencing here is actually the same issue as reported here?
