[SOLVED] After waking from hibernation, wireless is VERY slow

Hello,

I use a laptop Acer Aspire 7720 with Intel 3945 WLAN. It works correctly, but after I wake up the laptop from hibernation, the wireless is EXTREMELY slow, even when copying files across a LAN it only gets 100KB/s, when it could do about 2,5MB/s, also SSH to another box is painfully slow.

Any solutions (except for rebooting)?

Thanks.

The iwconfig stats seem OK.

[renan@sanctuary:~] >> iwconfig wlan0

Try reloading (modprobe -r and modprobe) the wifi card module.
