    I have a new Dell Inspiron 5110. I have a number of wireless computers and all the others, iPad, smart phone, etc, are having no problem. I tested the internet connection speed and it is faster to this computer than to the others, probably due to the N Adapter on a Dlink N Router. The others are all G cards. However, one of four things happens with Firefox, Chrome, IE and Opera.

    • The browser cannot find the server.
    • The browser times out many times before finding the servers
    • Sometimes it does find the server and the site, no consistency in the behavior.
    • When it does find the site, it is usually painfully slow.
    I have tried everything I can think of. It usually does come up in Safe mode with Networking.
    I set the DNS option to the Google DNS servers and for a while that helped.
    I have flushed the cache and winsocket with command line prompts.
    I have turned off the firewall.
    I tried disabling the v6 tcp/ip option in the adapter properties.
    None of this has made any difference.
    90% of my work is researching on the internet which makes this computer useless to me.
    I have run PC Cleaner, done thorough scans of my computer, etc. There was one virus that appered in the MSFT Essentials scan but it deleted it.
    Sometimes one browser will not work at all whereas another will work minimally.
    I see others complaining of this problem, but the threads do not seem to carry through for a solution.

    A new wrinkle is that I now see 3 wireless connections reported, two are through the miniports and have an X under them.

    I have no idea what else to try.
