iprowifi4965: Network performance degrading (regression)

[humdinger]

This is hrev57589, 64bit.

Used to work nicely before, but for some time now, throughput often degrades to below 50kbit/s after a while. Should have reported right after noticing, now it's hard to pinpoint the hrev it started... Any hints?

syslog just says:

ieee80211_notify_replay_failure not implemented, yet

and repeats of that every few seconds.

Details on hw:

device Network controller [2|80|0]
  vendor 8086: Intel Corporation
  device 088e: Centrino Advanced-N 6235

Try with an hrev from early December and see what happens there.

It seems that my wifi router is to blame. Or at least the issue doesn't appear to be the iprowifi4965 in general. I've been using my notebook with another wifi router for some time without the bandwith degrading reported in this ticket.
