Review on 💨 ARRIS SURFboard SB8200 DOCSIS 3.1 Gigabit Cable Modem, Cox, Xfinity, Spectrum & Others Approved, White, Max Internet Speed Plan up to 2000 Mbps by Jacqueline Mclaurin

My ISP is Xfinity (Comcast). Slow enough 100Mbps. Don't stress the SB8200. It can work fine for a few hours and then "stand still" for some reason. Clearing takes about 45 seconds, after which normal operation resumes. I don't have to drop it or pull the power cord. However, very annoying for a modern product. On the Product Information web interface page, I'm running hardware version 6, software version SB8200.0200.174F.311915.NSH.RT.NA (believe it or not!). Can't programmers come up with something more concise? I went to the Arris support page: No firmware updates available. My modem doesn't get as hot as others have complained. Warm but not hot. Also, going to the web interface page (192.168.100.1) is very intermittent. Sometimes it works, sometimes my browser (Chrome) doesn't get there. So it's not a configuration or firewall issue. The SB8200 has a LOST FIRMWARE. I can't believe they still haven't fixed the stall issue and this issue. This product has been available for several years. A very disappointing reflection on Arris. If (if) this modem eventually fails, I will not purchase any other Arris product. IMPORTANT UPDATE: This modem requires signal levels that Xfinity (Comcast) does not consider "standard". Comcast assumes the upstream power is 38-40dBmV, but this modem requires 45-51dBmV. Have your Comcast technician install an 8dB pad at the modem (he can do this locally - no need to change anything at the headend). My modem has been reliable since my technician installed a pad on my modem (2 days). I will post an update next week after watching it for more than 7 days. ANOTHER UPDATE: The modem has been working for 45 days without a single reboot. I can access the web interface (192.168.100.1) 100%. The speed test has always been what I pay Comcast for. IMPERATIVELY CONTACT YOUR TECHNICIAN TO ADJUST THE HIGH STREAM SIGNAL LEVELS TO THE PROPER VALUES. I think this will remove 80% of the negative reviews for this product.
