[ubuntu-uk] Wifi issues on 14.04

[Gareth France]

I posted recently about issues with my portable wifi hotspot. I am still 
experiencing issues but have now had the chance to further define the 
problem. The connection freezes, chrome simply states 'resolving host' 
and the page must be reloaded several times before it will load. This 
happens every 5 minutes or so. I? have been sent a replacement hotspot 
but this is the same, I have used an 11.10 boot disc and it works 
perfectly. On my partner's laptop which is also running 14.04 it is faulty.

The strange thing is that all other wifi connections work perfectly. The 
hotspot is a Huawei E5220.

Any thoughts greatly appreciated.
