my pc was connected via ethernet cable, roommates pc was connected wireless. my wireless adapter is not installed. a thunderstorm yesterday fried my modem. got a new modem. internet works fine when directly connected from modem to roommates pc. internet does not work when connected from modem to my pc. go into network connections on my computer and nothing is there. so im guessing there is a problem with the eithernet connection port on my computer? any one know how to fix this issue? thank you for any help!
