We have a WRT54G v2 router with 2 hard wired computers and a wireless G laptop. We need a means to hook a desktop computer to the wireless internet. Sometimes it's a computer we are working on for a friend. We were planning to get a WUSB54G however we saw 2 user reviews saying they run very hot and several people complain about them dropping signal. From information we find on this site I think we could use a WRT54G if we could figure out how to set it up. I suppose we could get a WMP54G PCI card and install it and later take it out. What will work best? Will we notice any increase in speed if we go to GS on the router? We're surfing the web, downloading files from the web, sharing files, and printers. Remember we're old so talk in terms that we hopefully will be able to understand. Thanks in advance for your help.
