Hi, I just had my ISP changed and they gave us a Wi-Fi Modem. The connetion is through TV cable that goes into the modem, then from the modem a telephone cable (broadband cable I guess) goes into the PC. The speed is very poor, however it's far better on my mom's laptop via Wireless connection, and also on smartphones too!! How is it possible? I would like to turn the tables since my mom really doesn't need that much speed.. what can I do?
