I have been with Orange broadband for 11 1/2 months. Contrary to reviews on the net I have had no problems at all. 8 meg unlimited, downloading at 8 meg speeds and connection only dropped twice in 12 months (fixed by turning wireless router off and on to re-boot)
I had no intention of leaving but threatened to move to Sky Broadband and asked for a MAC code. He offered me the same package but free for the next 6 months to stay on for a further 12. So 6 months free 6 months £19.99, works out at a tenner a month.
Hope it helps some of you guys out on here!
