I have a wireless environment consisting of a Linksys WRT54G (I will get the specific model) and 2 Nikon WT-4 Wireless Transmitters connected to Nikon cameras. 1 of the cameras is placed fairly close to the Linksys AP while the other is located probably 50ft away and through a number of walls. Using inSSIDer, the closest camera has a signal strength of -20-30dB while the furtherest is down around -60-70dB. The poor signal strength means that, from time to time, the camera can not connect to the server and the transfer rate is typically dismal. There are a number of other wireless networks active in the area.
A few people have suggested using a wireless repeater. However I recall reading something about this configuration causing more problems than are solved because of the duplication of the signal. There are also online suggestions for antenna modifications but most seem to be directional and perhaps not so good for receiving from the low-power transmitters.
Given that I have a Linksys WRT54G, I was investigating going down the path of DD-WRT and taking advantage of the multiple virtual interfaces to use it and another WRT54G in a AP/bridge arrangement.
Does a wireless repeater sound feasible with this setup? Is it worth spending the time to set up the 2 WRT54Gs with DD-WRT firmware?
