I have a wireless Netgear router with 4 ports on it. Now originally, none of my computers were able to connect to the router, but I have changed the channel wirelessly to channel 6 and three computers have now successfully connected to the router. Nonetheless, there is still one computer that is detecting a signal from the router, but stating that there is limited connectivity (even though signal strength is excellent.) This was what the original problem was and this was rectified when I changed the channel.
Would it help if I were to change the channel on the router again?
