i have the same router i bought on ebay. I just got it today and am unable to get it to work myself. After configuring it it still doesn't distribute the dns info even manually configured.
A friend of mine just bought the same one the other day and when I set it up for him I fought with it and fought with it. Finally I popped in the disk that came with it and ran it through the setup wizard and had it up in running in minutes.
If you accidentally reset it back to the factory defaults you have to go through the setup disk all over again. There's something about the way it does it that I can't seem to figure out. It's very odd when you run the wizzard it has you plug in your cable/dsl modem first to pull the information from it first and then it runs you through plugging in your router to the modem and your pc. after it does that it seems to work.
Of course the one I bought on ebay didn't come with the manufactures cd and they dont seem to have anything to replace it available online.
If anyone has the original disk for this router could you please make a zip file with the stuff on the disk in it and post it here. It shouldn't be to big, if it's not to much trouble.
I'll keep lookin and if i find an alternate download i'll post a link to it here.
BTW the manufaturer is actually Network Everywhere. Linksys just helps them promote it, like in walmart since they pretty much own the shelves where the network equipment is at there, lol
this seems to be the right one
