Hi. I have a Edimax EW-7128g[/url1fkd9azy] PCI wireless network card. It's working fine. The only problem, when i using network it's always stopping for a while almost 30 sec, after then working fine again.

There is no problem in Windows. I am using Debian GNU/Linux 5.0 Lenny amd-64, i tried etch and Ubuntu 8.04 and the latest kernel 2.6.28, it's have same problem.

I must solve this problem, when i play an online game, i am disconnecting in an action every time.

Also ping is not stable. Is that normal?
