Sony 50" TV bought, now need digital

Hi again guys, so after all the help you lot gave me in choosing what and where to buy my TV, i went to Power buy and bought the Sony Bravia 50" plus a tv 40" for the "outlaws" now what i need is some good advice on the next problem.
I live in a condo that allows me only one wi-fi signal, so i use that for my computer, which means i cant use the TV as a media center, i have a business online which requires my PC to be on all the time and connected.
So my TV is only connected to a coax cable picking up the We-TV package supplied with the condo, right i want the tv to be digital so how do i go about that?
This will not be a problem in my new house when its finished as i can connect everything through my own wi-fi connection.
Hope i have explained that correctly and you understand my problem.
Thanks Kevin

Hi Soapy Kev,

I have 'only one' WiFi signal in my townhouse. I am able to log onto that one WiFi signal with over 5 devices, my Bravia TV, iPad, laptop, my smartphone, my ladies smartphone and friends from time to time. Have you tried to access your one WiFi signal with more than one device?

I would be surprised if you couldn't share the WiFi signal with multiple devices. Give it a try and see what happens. :)

Hi Hoxman, i have tried before to connect my tab to the wi-fi in my condo,whilst connected to my PC, but it keeps saying i am already logged in and fails to connect.
Like i say, when i get into my own house this wont be a problem.
cheers for the suggestion
Kevin
