Thanks doganjo, but I was trying to browse to no avail whilst I was talking on skype. When trying to repair/find faults, windows said reboot/switch of router as only solution. Strange but true. When I rebooted (and reset) router I did lose Skype.
Smalltime - I had this problem in the past and Plusnet did look at stats and see my line was cutting out intermittently at the time and speeds had got slower and slower. But download speed at moment is fine 2.3mb (just tested it now, so got faster, but could be time of day, usually c 2mb), just kept losing the connection yesterday (other than skype).
Womble - thx, have an up to date master socket (I do remember city life avidly watching countryfile every week; now hardly have anytime to watch TV anymore...). But no, I accept won't have superfast speeds in deep dark Devon, just want something reliable and dependable.
I'm not convinced by the Thompson router (and it is a palaver to interrogate it/ change settings), so if I have to buy a new router (this is already the second one within my 12 mth contract) I might as well try a new ISP. If there is no contract tie in then there is nothing to lose is my thinking. Plusnet seem to have slightly faster speeds for my area but not of any use if can't browse (and I tried both Chrome and IE). Plusnet are actually owned by BT but that doesn't seem to help....
Kept looking at reviews for business broadband and none of them seem to have happy customers.

. May look at the O2 dongle as an option.....we do get a brilliant mobile reception at home, so may work.
thx
