I am running the most recent version DD-WRT on my Linksys WRT54G v4. For some reason, when I do a fresh install of an OS and they try to update it, I cannot. I can finally do updates when I go to a LAN party at some convention or a friend's house, but not mine, but after I do this somewhere else, I can then do updates at home. My question becomes, what is really causing this? Is my router causing this? How can you tell when your router is taking a dive?
