Been away for the weekend so haven't been able to chase this up until now. Took the mobile wifi with me to try it in a new location to see if it was a network coverage problem but it still wouldn't work (100 miles from where I normally use it). Contacted EE technical support today when I finally found a contact number that would work on a non-EE phone (0800 956 6000). I believe you can just use 150 if you do have an EE phone. After much to-ing and fro-ing, in an attempt to fob me off, the guy at EE seemed to eventually hit on the solution by pure fluke. I had my laptop switched on and opened on the Huawei wifi management page while we were talking and it suddenly sprang into life showing it had just connected to the internet. When I asked him what he had done he said he had done a Network Reset. So if you are still having the same problem, you need to phone EE and get them to do the same for the mobile number assigned to your wifi dongle. Hope this helps.
