[wireless] massive problems with network connections

irrlicht · 2011-11-17 15:18:20

Hello,

since the kernel got updated to 3.1 i got massive problems with my
wireless setup. I own 2 USB-adapters which are:

Bus 001 Device 005: ID 0ace:1211 ZyDAS ZD1211 802.11g                                                     
Bus 002 Device 002: ID 07d1:3c0f D-Link System AirPlus G DWL-G122 Wireless Adapter(rev.E) [Ralink RT2870]

Kernel modules are inserted and the firmware is installed for both adapters. Just like i told, both adapters were OK befor update to

Linux cassiopeia 3.1.1-1-ARCH #1 SMP PREEMPT

both are able connect to my router and the connection with both of adapters
are stable. The problem is, that
i can't browse the internet nor connect over ssh/rdp or whatever to other machines
across network. I have to wait up to 5 minutes before i one eg. archlinux.org get loaded but most of the time there are just timeout error. Sometimes the connections gains a full speed for a short period of time, but very soon the problem occurs.

I also tried to boot to live cd with older kernel versions - all is working as expected.

Please help me to solve the problem.

I found also that i get many RX packets being dropped. In that direction should i look? I have 3 mates(win and apple devices. they got no problems on same networtk just me).

Hm i don't know that exactly causes the problem, but i just changed wireless network mode from "mixed" to "mixed only N/g" and the problem seems to be gone. I'll run some tests. Don't really believe that problem is solved.
