A friend of mine is having internet problems, I wanted to see his power levels and SNR to see if they're out of whack. I told him to go to http://192.168.100.1/ but that page doesn't seem to work for him. If it matters, I think he was using wireless on his laptop. Will http://192.168.100.1/ work if he's plugged into the router? How else can I have him get his modem diagnostic page?
