I was with Sky Broadband since they introduce it. I used to pay £10 per month for the 16mb Max.
Always had problems because the telephone exchange (according to Sky) didn't support such speed, but they never did anything to rectify the issue. Last autumn, new issues with the connection started. Every evening, normally between 18/18.30 till approx 22/22.30 every so often the connection will drop for few minutes and then reactivated. Sky Broadband support, blamed the telephone line, then they blamed my phone wiring then something else. Sky support dropped to 12mb the speed to see if the issue will persist, but was fine for few weeks then back to the same problem. Fed of the hours spent on the (very expensive) phone calls to Sky Support and hours without connection, I changed my subscription to 8mb Midi for £5.00 and the problem seemed almost rectified. In May 2008 another problem arised. Sky did an update of the router and that blow up. On the phone with Sky support again for several hours (very costy calls) and a new reuter promised but didn't know when. Then some guy from support suggested to buy another router and try to see if I could connect, money wasted, Sky Broadband works only with Sky own router. Then Sky had some system issues so no one knew why the router wasn't sent. Then after more costy phone calls to support was told that: because my router warranty had expired, takes longer to prepare and dispatch another router. Why the warranty expired on the first place it's a mistery, and why should expired if you can access only with Sky own router? Another guy from Sky support suggested to use a dial-up connection, with Sky Talk(I was a suscriber to that as well) is cheap. Please don't listen to them, few and I mean few hours dial-up connection (not even 3 hrs) cost me over £45.00. After 16 days I manage to receive a new router and was able again to connect to a broadband service for which I was paying a subscription. Phone calls to Sky Broadband support (with Sky Talk that supposed to be cheaper) cost me almost £20.00, each call was for a minimun of 1hr & 30/40 mins with incompetent people.
I told Sky "off", still battling for a refund, and that's since May/June.
I subscribe to o2 Broadband, my connection is over 16mb speed and the only time I had to contact support (free call) was to rectify an issue created by Sky Broadband support team.
Please remember, no one gives you anything for free, and also "cheap is not chearfull". Basically you end up paying more.
