Review on 🔌 PoE+ Gigabit Ethernet Surge Protector with Full Protection - Gas Discharge Tube - Mounting Flange - RJ45 Lightning Suppressor - LAN Network CAT5/CAT6 Thunder Arrestor - GbE 1000 Mbps - Tupavco TP302 by Anthony Morrow

I am getting 1 Gbps from my. If not, try other cables. I grounded it by attaching a ground wire to the ground screw on the back of the UPS. Not everyone has it, but it's worth checking if you have. So I actually have a cable modem on a small UPS - literally the only thing on that UPS. I then have this protector between it and my router, which is attached to a second, larger UPS with everything else. I could have used a surge protector instead of the first UPS, but the beauty of a decent UPS (like the one with the AVR) is that it protects your equipment from dirty power supplies (high/low voltage and small blackouts). Since connecting my cable modem to the UPS, I have noticed that my cable modem restarts much less frequently. There could be a reason.
