Thanks both. I will try the extended cable. Re the first point, now that I am retired and now have a landline point I could try this. However, I live in the country and today I tried o2s offer of a cheap broadband deal, but they came back and told me that I was in a bad area so would not guarantee much better than I have with their dongle. I alteady changed from a vodafone dongle as that was even worse.
What other providers are there? I have only ever seen dongles on sale for VFone, o2 and 3G - don't understand the latter as when I connect with o2 it shows first as 3G anyway - then it changes immediately to something called 'O2 UK HSPA?'
Any more suggestions please.
Thank you
