connecting laptop to internet - issue with limited connectivity

[Dyewitness]

i have a sony vaio laptop, been connecting to net fine but since last week i can only access my own bt homehub network with limited connectivity? wont let me view any web pages, using a neighbours unsecured network to write this!

any idea what could be causing problems?

on the connect to network screen its showing my homehub, excellent strength but i cant connect!

when your connected - what IP are you being assigned?

Sounds like DHCP not working or your putting in the wrong access key.

lacking dns perhaps?

I take it you've tryed the unplug jobby?

On connection is it all auto signed or do you have to enter you WEP key each time?

 

[Dyewitness]

it auto signs in willie, just very confusing tbh

Worth changing channels on the homehub?

Take it everything works if you connect using cable?

As above try changing the channel, neighbours router is prob interfering
