I am using the legit 02UK tethering package

It seems that about every 10 minutes or so the tethering cuts out... internet is still working on my iphone but all connection on my PC has gone.... the only way I seem to be able to get the connection working again is by putting the phone into aeroplane mode and making it reset the 3G connection....

This is not a 3G issue as I am in central london and have full 3G signal....

Anyone else having issues?
