Thanks for your post and welcome to the forums. It's lovely having a new face in the Crowd.
I'm really sorry to hear about your experiences with your services since joining Virgin Media. This isn't what we usually hear about.
Currently we're aware there is an issue affecting some customers where the TiVo® is running slower than usual. You can combat this by trying this key sequence: Home > Thumbs down > Thumbs up > Play > Play > Play. You'll hear a 'ping' noise and the screen will go blank. When the screen comes back on you should notice the TiVo® speed up!
The TiVo® stores data that it uses fairly often in the cache so it can be called upon quickly. This sequence clears the cache and by doing this you remove all the background data freeing up some of the TiVo®'s memory.
With regards to your broadband, I've gone in to the account to see if there is anything obviously wrong here and I'm not picking anything up at the moment. All signal levels and power levels are right and there are no timeouts either.
As you have this connected via your wifi network it's worth seeing if changing the wireless settings may help. This link will help you check these: Wifi Tips
Come back and let us know how things go.
