    Erratic Internet Connection

    Using Ubuntu 12.04, wired connection, sometimes have superb connectivity then for several minutes will not be able to connect to new sites without a minute wait or receiving a message that the webpage is not available because the DNS lookup failed. Moments later it will work fine. Same results Chrome and Firefox. Have tried every remedy I've been able to Google up. Second computer with Windows works great. Any ideas?

    This sounds like a problem with either your wireless adapter or router. Do these problems occur on other machines, or - on the same machine - another operating system, such as Windows?

    Actually have 4 computers, two wired and 2 wireless and it's only the one I have with Ubuntu (wired) that is experiencing problems.

    Are you downloading updates?
    Have you tried rebooting Ubuntu and/or the router itself?
