<human>: So last night I was trying to connect one of our older computers to the Internet via Ethernet cable. Well, in the process I think I accidentally deleted something because now my wireless Internet wont work. I've tried everything I can think of and anything that Comcast support can come up with.

 I've unplugged the modem and the router and plugged them back in, and they all seem to be working fine because they've all got good lights on them. When I go to my computer, I can connect to the wireless network but when I go to the browser, it says that DNS lookup failed.

Sorry if this is in the wrong section, but I wanted to ask a bunch of people. Please help.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: my Internet isn't working. Tried to turn off and on modem and router. Reset modem. Nothing is working.
