I have a new iPhone 5 and tethering isn't working; laptop says it can't access gateway

Question

The personal hotspot braodcasts it's name and the laptop connects to the iphone and give internet access for about 30 seconds then suddenly it can't connect to the gateway (according to the diagnostics on my laptop [a toshiba running win 7]). It seems to come and go, but never long enough to get a webpage loaded or connect to my exchange server. I've reset the phone and restarted the laptop to no avail. Any thoughts?

Re: Anyone still having IOS 6 wifi issues?
created by mpa9366 in Using iPad - View the full discussion
Having done a lot of reading today and having found a very good online tablet magazine (will post link tomorrow) there seems to be a few tech bods onto the problem.
The magazine I was reading identified wifi problems within hours of the ios 6 release and have been analysing since then with almost daily updates - the story seems to be:
The apple authenthication transmission is normal, it should slip through event prior to a full handshake with the host network being completed - however if not authenthicated then apple will not permit the device to connect (kills the connection) this is designed to protect apple from counterfeiting. So thats problem 1 if you dont receive a token from apple.
Problem 2 is that ios 6 only supports ipv6 (the new ip protocol) whereas outside silicon valley a large proportion of routers modems etc are still ipv4 protocol.
So youre locked into ipv6 in a world where ipv4 devices are everywhere and apple have not allowed for the ability to handle both protocols. This is like GM telling you your car requires an upgrade, everything will improve etc and as part of the upgrade fits a fuel cell motor and stays silent when their upgraded vehicles are simply parked up because they cannot get fuel.
A very basic expectation would have been dual protocol handling - we know the HW supports ipv4 as all wad fine on ios5.
So its going to be hit and miss with networks - more hit than miss in techy areas like silicon valley, but more miss in places like where I am - a small town in rural Switzerland.
Only apple can fix this with a patch to enable ipv4 protocol handling.
There you go. you just need to buy a new router, I'm sure Apple has one for sale, cause it's not there fault for sure.
Wonder why people start to migrate to other devices ?
