[ubuntu-uk] 3G Connection issues

[Gareth France]

I was hoping someone might have some ideas as to what is up with my 
internet connection recently. I am running a 3G connection via a Huawei 
E5220 wireless hotspot. It's a fairly new device and for most of the 
time I have had it pages refuse to load, chromium just says 'resolving 
host' for a few minutes. Several page reloads later the page will load 
and internet will work for 5 minutes or so then the process repeats. 
This also affects streaming video and using my phone to remote control 
VLC over the hotspot.

However accessing the internet on my phone via the hotspot works fine. 
They have just sent me out a replacement and it's doing the same thing. 
I'm running Ubuntu 14.04 which I upgraded to a couple of weeks ago. The 
connection did work fine at first and I can't pin down exactly when they 
symptoms started but I do wonder if it may be a quirk of 14.04. I also 
experienced a persistent 'resolving host' issue on another network via 
wireless the other day which required a reboot to solve.

Any thoughts would be appreciated.
