Weird 3G dongle problem

[camelot1971]

I have a Huawei 1750 with a 3 mobile sim in it.

It connects fine via my laptop in Bristol but when my girlfriend uses the same laptop in London, it fails to connect to the internet. 3 have been more than useless! Any ideas on why that would be the case? The dongle is getting "full" signal in London too so its not that.

Could it be a 4G thing as the 1750 is only 3G (and Bristol is only 3G as well) whereas London is 4G now (I think)

Any suggestions appreciated!

Ah, maybe that's the case. I'm going to try a 4G dongle and see if that makes any difference.
