    Windows 7 random wifi connection issues


    New to Forum!

    windows 7 installed - setup is:

    Dell Inspiron 1521 laptop
    AMD 64bit CPU
    4gb Ram
    500Gb drive
    GIGABYTE Aircruiser N300 GN-WS30N-RH 802.11N b/g/n draft 2.0
    Draytek Vigor 2820N router

    Everything is setup OK - the problem is WIFI connectivity. Seems to be random connection, it will work OK for about 2-3 days, after reboots and sleep on and off. Then suddenly the W7 will claim not to be able to connect - it can see the router and connection, but everytime you hit "connect" it just returns with " unable to connect". Tried rebooting, running troubleshooter, removing connection and adding again, rebooting router(!) - but none work. I have Ubuntu installed on laptop as well - which connects everytime, even when W7 is claiming not to be able to, so I summise that the "network end of things" is OK, but W7 has decided to stop connecting. Very frustrating.
    This also happened with a previous WIFI module installed, exactly the same problem, so it must be W7 issue. I have 2 Win XP, 1 Vista Ultimate laptop WIFI and 1 linux box all using the same router - no problems, even when my Dell is unable to connect.

    Any help would be greatly appreciated, as I'm very close to going back to Vista, and giving up on W7. Which is a shame as W7 is very good otherwise.

    Hi and welcome to sevenforums

    I have a dell inspirion myself and the same problem happens to me. In my case it was a corrupt dell 1390 driver and the router I used (linksys). First thing I had to do was to kill IP-6 support. that gave me alot more stability. replacing the driver also helped. ifuond that the router was losing dns support because the firmware needed to be updated.

    Hope this helps

    Thanks zigzag, I will try this. I was previously using vista Ultimate - does that have IP6 support turned on by default? I don't recall having to turn it off, so if it was on once installed and updated, I guess it is on - but never had any issues with conections there!
    I'll keep you updated.

    since having stopped IP6 in windows 7, haven't had any issues with connection. I hope this is fixed in the retail release of W7, when IP6 becomes more important in the future...

    I've had the same intermittent connectivity problems with my Inspiron 1521 running Windows 7 64bit. I disabled IP6 using the utilities found here: How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista, Windows 7, and Windows Server 2008

    Working so far!
