Always have to disable then enable network adapter to get back online?

My netbook is running Windows 7 Starter. It is an MSi U135

At random intervals (can be every few minutes to every couple of hours) my connection will show a 'limited connection' and I have to manually disable then enable the network adapter. As soon as I have re-enabled it again the internet will connect. Sometimes it will force me to restart the netbook for it to connect again.

I have been searching for fixes for a few days now and have tried the following:

Disabled firewall.
Uninstalled antivirus.
Reinstalled the network adapter.
Completely removed the adapter driver from the system, then downloading one from the Msi website and installing the new driver.
Changed the router channels to a few different channels.
Made sure the box which says something like 'allow this device to turn off to save power' is unchecked.
I have tried the ipconfig /renew in CMD as an admin.
Also tried the ROUTE 0.0.0.0 command (read somewhere this could fix it)
I ensured I didn't have 'bonjour' on the system as I have read this can cause it too.
I even tried reinstalling the OS too.

None of the other netbooks in the house does this. (One running Windows 7 Starter and one on XP)

Any ideas?

All help is appreciated. Thank you.

You say ipconfig /renew doesn't make it return.

How about running ipconfig /release followed by ipconfig /renew?

Thanks for the reply. I will try that now

Tried it, however I had the same problem literally a few minutes after

It's only a temporary fix for me as well (that I discovered today), but I have found that if I kept doing it each time it died, my connection restored for longer each time. It's actually not died yet since I last did it (I suffer from a similar issue, but it doesn't say Limited connectivity for me, existing connections are maintained as well).

I find I only get this problem when torrenting. I know this will sound like a conspiracy but its the only time I get it. Random time of connection before limited connection appears. usually when I'm downloading the latest movies...coincidence maybe but its the only way I can get past it
