Ok there are 5 computers in my house 2 wired 3 wireless. All computers are set to pick IP and DNS automatically. Both wired PCs are on the net fine. One wireless laptop works fine, the other two connect to the network but have limited or no connectivity. Just last week I was having the near opposite problem with only the wireless PCs connecting to the internet, but I think that came from a different cause. After I fixed that (all of reinstalling the router set up disk) and now 2 of my 3 laptops don’t work. WTF is going on?
