It seems to me i'ts ath5k issue. Since I started this thread I've tried few more chipsets: VIA (vt6655) - has problems with sending packets, sometimes they are 'broken'. Most images don't reach mobile phone correctly. Ralink (rt2561t - rt61pci driver) - works correctly (and also uses nl80211). Range is poor - maybe it's a matter of hardware i've bought. Prism (ISL3886 - p54 driver) - works corretly (and also uses nl80211).
But thanks for pointing this out. It might be issue with ath5k<-> nl80211 cooperation, as well. Should I post a bug on kernel's bugzilla?
