I have a linksys WRT54GL at home, but the signal doesn't go all the way to one of the rooms. I live in an apartment with concrete walls.
I thought about installing a repeater, but apparently, after talking to linksys support, the only repeater they have doesn't communicate wirelessly with my router. They said I would need 2 access points to make it work.
I am pretty sure the WRT54GL itself can server also as an access point and broadcast signal to another access point. Well, maybe not a linksys one, but I could get one from another manufacturer,
with the powerline connectors you plug one end into your router and the other into the socket, you then plug in the second connector into another socket and then plug that using ethernet cable into your machine or another wireless access point (they do come in wifi versions that ive seen) which you then use to connect wirelessly to your laptop.
Hey skubaman, I've heard about Linksys' own repeaters not working with the WRT54GL. AFAIK, it's possible to use the WAP54G as a repeater, but you'll have to do some tweaking.
You'll have to assign the WAP54G and the WRT54GL a static IP each. Then, on each device that connects wirelessly, the Default Gateway has to be set to the WRT54GL's assigned IP. Lemme know how this works.
