Hi Mike thanks for sticking with me on this.

There are a few reasons why I didn't spend more time on the router once I'd established a few things:

1) The adpator actually hangs and it causes abnormal behaviour on the machine. ie. comms manager hangs if you attempt to try to turn off wifi and the spinner comes up. Even more abnormally this causes one of two scenarios, either a) the machine no longer turns off or if you manage to turn off it won't turn on again. So it's causing a major problem with the whole system.

In my experience a no-connect situation never results in a hang, it just times out and a list pops up of other alternative wifi networks it's found and you can always just turn wifi off or use the machine normally at this point.

2) Wifi connects to my router no problem, always has and still will first time from a boot (providing I tried to turn wifi on and it failed before the boot). After a hang and reboot it comes back always connected - doesn't even search, it's a solid non animated connection icon. In other words the card has woken up and therefore has no problems with my router once it's alive.

As an outside chance that the router is getting confused about a disconnect / reconnect I've also rebooted it in between just to make sure - but the router can't tell my machine to hang or fail to respond.

3) I have managed to get this to hang after deleting my settings, ie. stopping it from logging on to my router but rather letting it come up with a list of wifi points it's found. Most of the time the list comes up but after several tests I've confirmed that it does eventually happen. The symptoms are the same when it does. At this point no list appears and we end up with the same deal as in 1)

Having said that I can give the router a try - resetting it isn't too much of a problem as I can backup my configuration but I'm pretty certain it's not the problem bit when problems get wierd then logic sometimes goes out the window and one has to try everything.

I'll follow the registry one just in case but both those threads seem to be from people who can't get a wifi connect at all, usually for s/ware reasons. This is different to my problem which is an abnormal adaptor / system hang caused by accessing wifi.

I'm curious too. I thought a problem with the radio as a whole but I've tested GPS and bluetooth without any problems, both on plus the phone. I also thought that some kind of power issue. If the voltage to the adapter for some reason dropped below a certain point it would kill it till it was kicked back into life. Just a theory. What would cause this, I've no idea, faulty component, dry joint perhaps.

I also had similar thoughts as you on possible changes to the phone service till I finally found it could hang without the phone too just less. This is like 30% to 95%, but multiple on/ off of the wireless and a couple of machine power offs will get it to happen when the phone is off. It just takes a bit more encouragement. :)

As for 3G I have mine disabled. I only ever turn it on if I am out and need internet via my service. I got caught out when T-mobile's 3G kicked in, in my area and my battery life went to hell about 18months ago - since then it stays disabled.

EDIT: This may or may not be relevant but I hadn't figured out which situation causes failure turn off. If comms manager is hung after a trying to turn wifi off the machine WILL turn off but not back on again. I just found that one other dialogue that hangs is going into the Wifi settings > network adapters > IEE 802.11b/g wifi adapter. This dialog hangs solid. At this point the off button does nothing. It's a reset. Just a strange reversal but it's also a confirmation that the adapter itself is the problem or has been put into a very nasty state.
