Review on TP-LINK TD-8817 ADSL2+ Modem with 1 RJ45 and 1 USB Port, Bridge Mode, NAT Router, Annex A Support, ADSL Splitter, High-Speed 24Mbps Downstream by Michael Bryan

Almost all modern computers are equipped with gigabit ports. Some routers too, like my case. Long story short, I only recently started experiencing service outages while using this modem and almost had a different one shipped. After some much needed troubleshooting, I decided to try a different gigabit port. On the hardware side, it connects and disconnects instantly. After setting the speed and duplex to 10Mbps (100Mbps didn't work), the connection was stable and I had stable uptime. Since my speed was 10 Mbps anyway, I didn't care. To reconnect to my entire house (not just my computer), I connected the ethernet connection to a simple switch and then back to another router. Right now everything seems to be auto-negotiating at 10Mbps (including the gigabit port to my router), but the connection remains stable. If you have a router with gigabit ports, you may want to buy another plain Category 5 cable to plug between your modem and router. This seemed to help me and now I have uninterrupted service most of the time. (For reference, I've tried a built-in Intel Gigabit card, a built-in Realtek Gigabit card, and an optional Intel Gigabit card, and none of them will auto-negotiate properly with this device, and they worked fine.)
