Thanks for your post and apologies for the time it's taken for us to reach your post. We've been a little behind lately and are playing catch up.
With regards to the TiVo® running slow, any devices connected to the wifi wouldn't affect this. If your wifi is also running slow then it'll be worth changing the wireless channel you are on to help improve it. This link will help you do that: Wifi Help
As the TiVo® is running slow, it's worth giving it a reboot to see if this helps. Also, go through your recorded content and remove anything that you no longer want on there. Has this made any difference?
Come back and let us know if you are still having an issue.
