    After years of my laptop running flawlessly, I've started having major problems connecting to my router/the internet.
    I noticed the problems started happening after I did a huge 14gb download..
    My computer constantly but randomly disconnects for random intervals of time. If I'm lucky it'll connect just fine, but once it disconnects, it'll most likely not work for quite some time.
    The other computers/cellphones/etc aren't having any problems with connecting, and it's only my laptop.
    Sometimes it seems to go on a "Identifying...(Name) No internet access" loop, or it connects to the router, but I get no internet access. And whenever I troubleshoot it, it never really helps anything, and I never get a consistent reason as to why it isn't working.
    The laptop is an Asus running Windows 7..

    Your media is showing "disconnected" and there's no IP address, Gateway address, Subnet mask, etc.

    Possible reasons (but not all):

    1.) Drivers: First thing I would try to narrow down. Since you had the PC for awhile, chances are: several driver updates could have happened. Actually MANY. So, it's possible that a driver update caused an unreliable card. If not.....

    2.) Channels: Your network card could be changing channels often, causing disruptions in your connection. This doesn't explain the no IP address etc though. If not.......

    3.) Faulty hardware: Your network card could be going south. Try purchasing a USB wireless adapter if you can't figure it out with the help given here (if and only if though)!

    ---

    TO TROUBLESHOOT:

    Restart your PC and press F8 repeatedly, immediately after booting until
    you are presented with the advanced boot menu.

    Then, when presented with the menu choose "Safe Mode With Networking"

    In safe mode, see if the problem persists. If not, your drivers are the problem. If it does, hardware (or configuration issues) could be to blame.

    I've updated all the drivers I could think of updating, and nothing has changed..
    But I went away for the weekend, and brought my laptop with me, and I was able to connect to the internet perfectly, so I guess it's an issue with my router at home/configuration..
    I tried the safe mode with networking and there's no difference..
    Any other ideas?

    I guess that the guest network does not cause interference, but I'd turn it off for a test anyhow.

    You might try WPA-PSK TKIP encryption, although what you have shouldn't be causing an issue.

    Turning off the guest network and changing the encryption didn't seem to work..
    Lately i've been noticing that whenever I have an internet connection it shows that i'm connected to two routers/networks? One is home and one is public. And they're both Wente, except one is wente 2 and the other 3..
    Whenever I start to lose connection the public one becomes unidentified.

    If "it" is ipconfig /all please post a copy. Otherwise, please attach a screen shot of whatever "it" is.

    Oh. Sorry about that. I have to retract my statement from earlier about Wente 3, as well. It doesn't seem to show up anymore.

    I guess we should see an ipconfig /all that corresponds to a time when you have those two connections in the Network and Sharing Center. It's puzzling.

    I don't understand the two Default Gateway entries, nor where the 192.168.1.1 is coming from. Maybe that relates to that Public network in the Network and Sharing Center. Do you have anything on your network with addr. 192.168.1.1?

    If you can't explain the above try ...

    (From a JohnWill post)

    TCP/IP stack repair options for use with Vista or 7.

    Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.

    The address seems to be from Wente? I'll do the repair soon.

    It only shows one router that I'm connected to now, but nothing has really changed in terms of performance.. I also forgot to mention that when I noticed my internet started acting weird, my internet speed has gone down A LOT. I lag a lot during games and stuff, when I never did before.
    Also, it probably isn't helpful, but I noticed it started happening after I downloaded this game.. And during the downloading process, I guess I ended up taking all the bandwidth.. Whenever I was downloading the game, no one in our house was able to connect online, except me, but only the download was able to connect.
