Hi all. I am planning to have a home network with 3 PCs (initially). One PC is desktop, will be connected with Ethernet cable to the router. The second will be a notebook with WiFi connection. The problem is withe the third PC. I need to connect it with WiFi. But the computer is located 2 floors above. The distance between the router and the 3rd PC is about 6 meters but there are a reinforced concrete ceiling and floor between them. Now I think which one of the WRT series router would be good enough to establish at least 50% signal strength for a connection between the router and the 3rd PC? Of course I prefer the cheapest possible model (like WRT54G) but I have read that latest WRT54G revision is not as good as older ones and WRT54GL is more recommended (although there are rumors that also WRT54GL latest revision is not as good as the earlier ones). Only I do not know how it is relate to my case. Has WRT54G worse signal strength or speed than WRT54GL? Other extra features do not interest me, I need just basic routing, DNZ, MAC clone, DHCP, WiFi. Thanks for any help.
