I am currently running 2 PCs through a Linksys Wireless G (Model WRT54G I think) on the main PC and then my PC has the wireless G USB Network Adaptor (Model WUSB54G). This is also on Cox highspeed internet. Up until about 3 weeks ago my signal has been great. Since then it REALLY is slow, somewhat reminescent of dial-up on a bad day. The PCs are both on the 1st floor of our home, about 35-45' apart, seperated by one bedroom door. Is there any way to boost the signal? Will those range expander's or antenae's help or are those just gimics? Any suggestions would help. Perhaps I need to run some type of diagnosis on my PC and see if I haven't got someone using our network that's not suppose to. I was pretty sure I was safe, but perhaps not. Could be a neighbor has some new toy that's being used... I just don't know. Thanks.
