If this problem is addressed in other forums, I'm sorry for the duplication. I have a WRT54GS & a WRE54G running on a mixed mode network. My WRE54G will sometimes drop the connection that feeds the computers attached to it, but then pick it right back up. The machines that get their signal from the expander consequently have to repair their network connections in XP in order for them to continue working. I have the latest, greatest firmware from Linksys running on the range expander (1.04.7 I believe) and the latest HyperWRT firmware, which is pretty sweet by the way, running on the WRT54GS. Any ideas on how I can make the connection be constant on the range expander? Do I have a bad expander? One problem that I have, which is unavoidable at this time, is that the router is in a different building than the expander. I'm sure that is the biggest problem but does anybody of anything that I can try before I give up and do some more networking into the other building? Without the expander, I can see a signal into the other building, but it doesnt' reach the other end of the room. I did spend about 20 minutes on the phone with Linksys tech support the other night. After polishing up on my foreign languages, I could make out a little bit of what the tech said. He told me that I needed to back off my firmware verson on my router to 2.07.1, instead of the newest 3.whatever. I asked him why I cannot run the newer version with the expander? He wouldn't give me a straight answer, he just said that the older version is compatible with the expader. Apparently the newer one is not?
