Approved Modems SB6183 Review
The ARRIS SB6183 is one of 6 cable modems we tested on our Comcast XFINITY 200 Mbps plan. The results were as good as you can get. Setup via XFINITY’s Online Activation was super easy. No call to Comcast was needed. As a matter of fact, we were up and running in just over ten minutes. After running the speed test on the modem and connection, we reached an average of 207 Mbps download speed after 3 tests. So it is safe to say this modem does what it was designed for. We ran the SB6183 night and day for 7 days and it did not overheat at all. Additionally, during these 7 days, we never lost a connection while online. Overall, I personally give the ARRIS SURFboard SB6183 5 out of 5 stars.
