    Hey there,

    I considered myself quite adept at fixing computer problems, but since I visited my Dad's house for christmas, and searching all over the internet for a possible fix, I haven't found one for a week, so I resigned to actually asking for help, and I considered this site to be the best looking one... ^^

    The problem itself, on my PC which I have connected to the wireless network in my house, I am on the second floor, in my room while the router is downstairs in the living room. While it (most of the time) remains persistently connected, frequently I find speeds slow to un-useable levels, or to the point where I cannot ping the default gateway at all, it just lags out.

    The actual wireless network never actually disconnects (The icon in the system tray remains connected with a fair/good signal) but in reality there can be no connectivity for several minutes.

    All other computers in the house, including my notebook which I have less than a meter away from my PC, work optimally, my notebook never disconnects or experiences slow or sluggish connection, and even when my PC does have connection, speedtest.net shows almost double the speed on the notebook.

    Also interestingly, when I feel that its been sufficiently connected at decent levels for a period of time, I load up Starcraft 2 (an online game) which seems to make the connection sluggish and slow, and finally non existent after around 30 minutes of play, I am not sure if that's a coincidence or a factor but I'll include it just in case.

    As I said, I attempted to search the internet for a fix, so I have tried several things, and I will post all this additional info at the end.

    As for the extra specs, to connect to the wireless I am using a Belkin N150 Enhanced Wireless USB Network Adapter (F6D4050) version one.

    My Dad's router is an old BT HomeHub Version 1, it seems to be updated to the newest firmware. its firmware version is Software version: 6.2.6.H.

    I have used the sysinfo for basic specs in my profile, however I can repost them if your feeling exceedingly lazy. :)

    A print screen of my desktop showing when I was Disconnected is attached.

    I disabled all firewalls, and even uninstalled AVAST! for good measure, the problem still persisted.

    I downloaded netsniffler on my laptop, and checked that no other wireless networks were sharing the same channel as me, I tried them all from 1 - 11 with no avail.

    I redownloaded AVAST and searched for virus's ect and found nothing.

    I tried to update my wireless adapters drivers, but I seemed to have a problem with this; the drivers say they were made in 2008, by ralink, and version 2.2.3.0, but I went to the Belkin website, downloaded drivers and didn't change, so I assumed they was okay.

    However later when I still could not fix the problem, I went to the ralink site directly, and found that the chipset that is used in the Belkin adapters have newer drivers, version 3.1.3.0, so I downloaded them, attempted to update my drivers, however windows told me they couldn't update successfully...

    So I don't really know how to go from there, whether I have the right drivers or what... :/

    I changed the security from WEP, to no encryption at all, no change.

    I had been able to connect to my network in my flat at university with absolutely no problems a few hours prior to coming to my Dads...

    I attempted to turn off my IPV6 connection no change,

    I can't move my desktop to the router to check the connection unfortunately, but thats the only test I haven't been able to do, but seeing as my laptop connects flawlessly, my PC does sometimes have a connection to the internet (although unstable and intermittent) I am unsure what a successful connection via ethernet would reveal which the other tests had not...

    I have reset the router, and reset its power cycle several times, it doesn't show any consistent or significant effect, similar with removing the adapter and plugging it in again.

    I notice the disconnections are more frequent around busy times (9pm- 12), however that does not fully explain it as A. my note book and everyone else in the household report completely fine connections, and the intermittent connection occurs at all times of the day ( the ipconfig reports were taken at 3:39 AM)

    I have tried several other tests including flushdns and release and renew, manual IP assignment, switching from google DNS, to automatic DNS assignment and back again to Google DNS.

    Here is the ipconfig/all of the working notebook:

    I have tried all my USB ports on my PC, no change, they seem to be functioning fine with other devices.

    I have possibly tried other steps which I can't recollect, however if I have missed out any information or steps that you usually need to take please tell me and I'll be happy to carry them out or inform you.

    Sorry for the giant post, I just thought I'd include as much information as I could, it must be very frustrating to have people asking for help and not providing any workable information...

    Nice thorough description with little if any extraneous stuff. :) Nice job.

    Your ipconfig /all results confirm your statement that you do not lose the connection; the failure of the pings to the router say that you do lose communication.

    I may have missed it, but another clue to what's happening may be what you do to get the connection working again.

    The adapter could be dying. You could try the adapter with another computer and/or try another adapter with the problem computer to get a 2nd or 3rd opinion.

    The driver should be the latest on Belkin's web site.

    Vista sometimes struggles with WEP encryption, so if that is what is being used I advise to try w/o encryption or with WPA to see if there is a difference.

    What, if any, non-Windows firewall or security suite do, or did, you have on this machine?

    There could be wireless interference that affects one adapter more than another or that is only showing up in the exact spot where the Belkin adapter is. For when it's working well and for when communication has been lost please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector.
