Went round a friends house on friday to set up his P2P and forward ports and what not (Lynksy Wireless router & NTL 300k Broadband) all went well we left it downloading and went out. We came back maybe 4 hours later and nothing was working, no pc in his whole network was connected to the net, even his second computer than was connected by CAT5 Cable didn't work. No website would ping. I tried getting into the router settings (http://192.168.1.1) in IE (didnt work in FF for some reason) and IE gave some bullshit you are not connected do you want to work offline or try and connect so it wouldn't let me get into the router settings. Tried refreshing the router, pc's, modem everything.
Anyone got any ideas?
