Ahh brilliant, a guy from whitwick
Not good news im afraid to say, iv'e had a report from a guy from coalville that works with my mother... guys a network admin, says it's definately ntl's doing.... his connection is shot up the same as our own.... middle of last week/present.
Im getting exactly the same as yourself.. browsing is hit and miss.. start a download.. it grinds to a near halt, the whole lot.
Where from here i don't know.... but id imagine ntl must be on the case if the whole of coalville is suffering the same as us folks from whitwick.
Aproaching a week though.. kinda praying they fix it by next... i miss my battlefield.. i got the week off work
Whatever you do though... don't start ripping up your computer... been there done it myself... ill save you or anyone else listening the trouble
