If you are going to hook up your TiVo, they need to say "wireless modem jack" instead of "wireless phone jack". The wireless modem jacks will of course still work with regular telephone, but they are designed to allow modems and fax machines to be connected. The cheaper wireless phone jacks rarely work for modems and you have about 50/50 chance of the fax machine working over them (just from my experience). I would return them and get one that actually says "wireless modem jack". Otherwise, you will continue to have an unreliable and/or very slow connection. Good luck.
