Hi, I think I've got a problem: When downloading via my ISP FTP site(http://testvitesse.videotron.ca) I've got only 2.8 MBits of downloading speed over my WI-FI connection. With the same computer but wired connection, I have 4.8 Mbits.

What can do this problem? MAXMTU or other tweaking like that?

My config:
WI-FI D-Link AirPlus G DWL-G122 USB adapter 54 MBits Signal Excelent (4' from Router)
D-Link DI-524 Router (No encryption active)
Wired Connection via SMZ EZ PCI 10 MBits

Thanls
