Neighbour has a long building consisting of several flats, Satellite Broadband into a T-Link TL - WR841N. Signal quite reasonable throughout about 2/3 of the building, but could do with a boost. Tried an Edimax 300M Range Extender, which would work for a day or two, then fail to connect. (probably because I set it up wrong!) Also I have a Lynksys WRT54GL W'less Router and a Belkin Wireless G Router F5D7230-4 at my disposal.
Which combination would you choose, and what advice to set up? I assume it would be best to keep the T-link in place as it's Wireless N?
