Hi Neil,

I had issues with my phone - Windows Phone 7 - of a similar nature.
What was happening was that every time the phone was turned off I lost
connectivity to my router and it wouldn't come back no matter what I
did.  It turned out that HTC in their all-too-finite wisdom had screwed
up an update with the result that every time the phone was turned off it
changed the MAC address!  Yes, immensely stupid I know, but they did it
and it took them a couple of months to bother to fix it, however they
did eventually.

Here's something you could try.  In my router I can assign fixed IP
addresses to specific MACs, so that for instance my NAS box always has
the same IP on the network.  It could be that the DHCP lease is running
out on your phone's IP and for some reason it's not refreshing
properly.  Rebooting the router may be pushing a new IP to the phone
rather than wait for it to ask for one.  Assigning your phone a fixed IP
would solve that, if indeed that is the issue.

Kind regards,

Julian

Further to my previous email, I have checked the MAC address shown in my
router with the one appearing in the phone and they are completely
different. Strange. Resetting the router is not likely to change
anything on the phone, is it? Yet once reset I can log on to the wifi no
problem. (For a while anyway.) All very strange.

Hi Neil,

What I meant was to make your *router* not your ISP give the phone a fixed IP address, not via DHCP as it normally would. On my router (the poorly named Virginmedia Superhub) I can tell it to reserve specific IP addresses for particular MAC addresses.

e.g. when I turn my NAS box on the router sees the MAC address and knows to give it the same IP address every time: 192.168.0.2. The same with my desktop, 192.168.0.3. That way if I use any IP specific software I don't have to mess about. Other devices like my tablet just get a dynamic IP from the DHCP server in the router.

When you say you've checked the MAC address shown in the router with the one in your phone, do you mean you've checked the list of connected devices?
