Had to reset my wireless router the other day and made no changes to it. Once back up my laptop immediately found the connection on connected to the internet. A few hours later I noticed that the laptop was disconnected and my modem wasn't even displayed in the connection list (even though about 8 others were listed).
This has happened three or four times now in the last couple of days and the only way to get around it is to reset the modem again. Any ideas of what's wrong?
