I have the same kind of problem.
Only laptop is Dell D620 and WinXP. Have no idea!
Pinging different AP-s gives the same result: some 3-5% packet loss. Trying other computers - no lost packets. Trying same AP over cable connection - no lost packets.
Exactly the same problem here:
- Dell D630 with Intel 3945ABG
- Win 7 32bit
- Latest 18.104.22.168 driver from intel
- No problems what so ever when using ETH NIC directly
When using wifi, I get constant 3% packet loss. Symptoms go so, that every 10 to 20 sec's the ping starts to grow (regardless if ping'ing to local network IP or server in the internet) and then there is complete halt. During that time all network activity stalls. Funny thing is that all the VPN and SSH connections do keep alive; halt is usually 3-5 secs. But it makes using SSH or remote Citrix sessions like eating gravel. Not so nice.
I tried this now with four different WLan AP's, with or without any security settings etc. So this is spot on problem just in my PC.
Any tips from here would be greatly appreciated, before I finally throw this laptop in the sea.
