I did start in safe mode, but it did not help because I need some thing that uses the network constantly for about 15 to 20 minutes to see whether the network is jamming. There is no other indication, ie. it says 'connected' in the taskbar, and is listed in the modem page even when it is jammed.

Now I have to say, when this jam occurs, and as it is stuck jammed, the desktop, connected via lan cable, and phone connected via wifi, does not experience any problem with internet connectivity.

I updated the driver manually from the intel site, when this problem started. After you mentioned '7 certified', I tried updating from the device manager, and it says up to date. How do i get a '7 certified' driver?

I was using WPA-PSK/WPA2-PSK ; AES, then I tried unsecured and now im back to AES.

Now, you mentioned, a software could be causing the problem. I think that may be the case. Right now I am, using my desktop, playing a movie via remote desktop, from the laptop. No other programs are running on the laptop and there has been no jam for the past 20 minutes. I closed remote desktop, and tried reopening and it is still working. During problem times, the remote desktop usually looses connection pretty often.

I think the problem program is uTorrent. My ISP offers unlimited transfers between 0200-0800 and i have set up uTorrent to transfer only during this period. It is during this time that the freezes mostly occur, after u torrent has run for about 8-20 minutes.

After you mentioned the chance of a software, I googled 'utorrent freezes network' and the like, and found that when u torrent exceeds a certain number of connections, some routers tend to lock up. I don't know whether this is what im experiencing, since my router doesn't freeze, only the laptop-router link freezes, as I mentioned earlier with the desktop and phone.

I kept remote desktop open for about 20 min, with utorrent running, but not transferring, and no jam. Now I have to wait till 0200 to try anything else.
Did you say uTorrent?

You do realize that uTorrent uses unlimited upload and download bandwidth unless you throttle it down? I won't get into the many other dangers of downloading torrents because I'm sure that you are aware of that. Needless to say this is enough to jam up or use up all of your band width.

You should throttle down uTorrent by going to lower right taskbar, small arrow, or just go into uTorrent settings and throttle down your uploads and downloads or better yet, turn it off completely and don't let it turn itself on which is the default setting.

The absolute max internet speed i get is about 190kB/s down and 70kB/s up, so, even at full speed, utorrent cant possibly jam a 87-144Mbps wifi connection, I hope. Secondly, when it is jammed nothings works, not even utorrent. The status bar shows 0.0 kB/s up and down. At this point, utorrent is stuck, browsers can't open anything, remote desktop won't connect, I cant open the modem config page, all from the laptop, and I cant see the laptop in the network from the desktop. The desktop itself even at this point can access the internet fine.

Yes it can and it will. It greatly depends on how many torrents and how many peers, there are too many variables involved and they have nothing to do with Windows 7. Turn off uTorrent of suffer the consequences.

Hear me out, please.

When it is jammed nothings works, not even utorrent.

Every thing is jammed, there is no data transfer taking place to/from the laptop. The status bar in u torrent shows 0.0 kB/s up and down.

At this point, utorrent is stuck, browsers can't open anything on the laptop, remote desktop won't connect from desktop to laptop, I cant open the modem config page from the laptop, and I cant see the laptop in the network from the desktop or desktop in the network page of the laptop.

The desktop and phone at this point can access the internet fine, and fast too, because there is no other traffic.

Even if I shut down utorrent after this jam, nothing happens. The connection still remains jammed.

And also, I was using utorrent just fine, with my older modem that doesn't even have 802.11 n, no settings have been changed since in utorrent.
