the router is linksys WRT54G
and the nic is a Linksys Wireless-G 802.11 Portable USB Adapter
I also have the nic connected to about 15 ft of usb2 extension cable so I can get as close to the router as possible.
I get 4 bars out of 5 of strength with a signal of 'very good' yet everytime I initiate a high speed internet download, or a local lan download I instantly get disconnected. it also randomly disconnects on its own when im not downloading. sometimes loading a webpage causes it to disconnect too but usually it can handle that.
any suggestions are apreciated.
