I'm sorry to hear you've had problems with your WIFI.
I can arrange a call for you from a Faults Manager to help get this sorted.
The call would be 0900-1800 Monday to Friday, when would suit you best?
I joined TT last August too. Plus I kept my other provider for an extra week Good job as, like yourself, when I came to use it nothing worked. I called and an enginner came out a few days later. He told me that my 3 year old laptop's wireless software was too old for TT's router. He searched for an update and downloaded this for me - plus a virus. After a trip to the repair shop, I tried the wifi again. Nothing. I bought another laptop that was 12 months old. Still no good. I bought an older TT router. Still no good. I have to use wired which works fine. I have phoned many times but was eventually told I would have to live with it.. I have a business and many of my products are sold on ebay so I am constantly checking emails and tracking sales. Now, I have to sit in one place to do my work. Not ideal. I have 2 mobile phones and an ipad on contract with 3 and have been looking for another supplier. I don't think I will be using TT and once my TT broadband/phone contract is up I will be gone. I cannot believe that in 2014 a company cannot supply wireless internet.
