HTC Desire series

[njs]

My Desire has just started having problems connecting to wifi. Not changed any settings as far as I know, it has always connected without a problem for the last 9 months. Now when I try to connect it says it has connected but is searching for ip address,  it then stays like this for about a minute and then disconnects. It then tries again and the same thing happens.

Any help would be much appreciated.

 Have you tried deleting the connection from the phone and then re connecting? Settings may have got somehow corrupt.

Yes, have tried that but it made no difference.

Check that your router is still set to hand out DHCP addressing.. Also try changing the broadcast channel in case someone else nearby has set up a network with a WiFi router on the same or nearby channel.

I have it set up to pick up different wifi routers depending where I am ie. at home, at parents, at in-laws.  It has stopped working on all of them.

What happens if you set a manual IP address, then?

[njs]

not tried that as i don't know how to find the ip address.

Have you recently updated to Gingerbread?

I've got the same problem.

I have a Desire S (running Android 2.3.3 aka Gingerbread) and it works fine...There is a small issue of the wifi signal being attenuated if the phone is held or placed on a surface so as to obscure the antennae, but this has nothing to do with the wifi connectivity.

If you don't know the IP address range of your own router (and I'd start diagnosing the issue there), then you need to get into the router setup config and have a look...

By default, most home routers (and a lot of commercial ones) come set with IP addressing set to DHCP and in the range 192.168.0.1 through 255 (or occasionally 100). Obviously this can be changed...but if you haven't done anything then the router is most likely set up like this...

The router takes the address of xx.xx.xx.1 and this is the default gateway.

Devices take subsequent addresses in sequence.

Subnet mask would be 255.255.255.0

 Its stopped on all of his routers though which would suggest its the phone thats the problem as the routers are in different locations.

 I know its a pain in the Ar$e but have you tried a factory reset on the phone? Back everything up first though that is not already on your sd card like sms / mms and contacts if you dont use google for them. You can get apps to do this on the market if you dont already have them.
