router compatibility with SB6183

I have a SB6183 cable modem that I’ve been using with a NETGEAR R6300v2 router that’s worked great until a bad thunderstorm came through and did something to my internet/wifi. The technician said I need a new router. I connected a NETGEAR AX1600 WiFi 6 Router and it didn’t seem to fix the issue. Should it? Any router recommendations that would be compatible with a SB6183?

SB6190 not approved by Spectrum but packaging says it is. Is this a spectrum issue or false advertising!

SB6190 reboot remotely

How can I reboot the SB6190 remotely? I’ve owned surfboard modems in the past that I have been able to reboot via the web interface, but I don’t see the option there for this modem. If not through the web interface, can I SSH or telnet into it? My cable provider can reboot it remotely. Thanks,Justin

Two different SB6190's reboot themselves multiple times per day with the same log messages

I’ve had a SB6190 that was working fine for more than a year. A few weeks ago, it started rebooting itself multiple times per day, but once it rebooted, it reconnected to Xfinity just fine. Unfortunately, it would just do it again in a few hours, and obviously, internet service is interrupted for about four minutes each time. Xfinity sent a service tech, who checked and said there is nothing wrong with their cable. He said the SB6190 should be fully supported on the Xfinity network, and suggested I buy a new one. I did buy a new one, and it behaves exactly like the one that is more than a year old. It works fine, until it reboots itself, and it does it just a frequently as my original SB6190. What do I telll Xfinity, since it’s obviously their network? Two different SB6190s (both tested when plugged into the wall and also tested when plugged into a UPS/surge protector) are acting identically. In addition, there seems to be two entries in the logs that correspond to the timing of the re

SB6183 Intermittent connection

My internet drops out intermittently (usually for a few seconds at a time, but VERY often). I’ve power-cycled both router and modem. I checked and have the latest firmware upgrade for my router. How can I explore to see if I could be having a problem with my modem? Thanks for your advice!

403 Forbidden not resolved

I see that others are also getting the 403 forbidden message when trying to connect to the cable modem interface. My modem is the SB 6190. I tried EVERY suggestion listed in this forum, and chatted twice with Arris tech and we went thru all steps, no go. I asked both Arris tech’s do I actually NEED to connect to the interface, and if so why? Security reasons? Both tech’s told me to rest assured that there are NO security issues if the interface can’t be reached and UN / PW can’t be changed. Is this true? Anyone know if this is true? If it’s true, why is there a need at all to connect to the interface? Really a terrible feeling to be locked out of the interface and not knowing if I’m now vulnerable to being hacked. I’m going to get a new cable modem. NOT and Arris.
