Virgin - IPhone - Loss of WiFi

Unusual problem today:

I have an Iphone 5S and wanted to upgrade to latest OS. I plugged Iphone via
USB in to my laptop which is connected via WiFi to my Virgin Super Hub.

As soon as I plugged in Iphone - I noticed that web connection had dropped out:
no WiFi signal.

The problem is quite repeatable: tested on two different laptops and different
browsers (one laptop on W7 prof and the other on XP prof) When I have two
laptops on the WiFi network: the network connection is only lost on the one in
to which I have plugged the Iphone - the other laptop continues with Internet
access - so the router is still working OK.

If I unplug Iphone - then the network connection from the PC gets
re-established.

I plugged one laptop directly in to router - and Iphone into laptop: Iphone
updated OS fine.




Any ideas?

 

A friend experienced a sudden drop on his wifi connection while using the same brand and model. He contacted an Apple store and was asked to have his unit rebooted (take out the battery as well). Unfortunately, this did not work. He was advised to bring his phone and fortunately this was replaced. By the way his phone was about 3 months old at that time.
