We don't have a landline in my village so I have something from Deutsche Telekom called a Speedport Router, which works by satellite in a similar way to your mobile phone, and is fast and no problem, I rent it and it goes on the monthly phone bill. Is there not something similar in the UK?
OG. I smile when people talk about "free WIFI in coffee shops" it's free but you are of course expected to buy at least a cup of coffee, minimum usually 2 quid. Last time in England with a lot of business to do and a laptop I spent a fortune on coffee having to go in three or four times a day, in the end I was suffering from caffeine over-dosing.
