Pete is correct about the new superhub. I have just received a letter inviting me to upgrade to the 30meg service from the 20 for £30 one off fee. I have taken them up on the offer as the new service will be £1.50 per month cheaper so it should pay for itself after a while.
The new self install superhub comes in 2 days So hopefullt It will go smoothly.
I was told that S/Hub is the same as 50meg hub but that service needs an engineer to install (at £60) why do you think that is?
