Alternate way of downloading Fing?

I just bought an SB8200 and in addition to having issues with connecting to Xfinity during peak hours (still don’t have an answer on that from Arris or Xfinity) I am trying to download Fing. When I go through the initial set up where it says it’s sending an email to download and set up, the email never arrives. Any suggestions?

SB8200v3 only 1 connection even with switch

I got connected with xfinity with my SB8200v3 and I used 1 ethernet port to connect a switch to. I have 3 PCs connected to the switch but only 1 is getting internet. I tried looking into the setting of the modem and the app but neither one will give me any options. I have been trying to look this up and can’t figure out anything other than I might be in bridge mode but can’t figure out how to get out of bridge mode if I am.

New Modem/Router STILLSlow Wi-Fi on SB8200

I posted this about 2 months ago. I made the adjustments, but I’m still having issues. In fact, my “guest” network is actually much faster than my main network so I’m not sure what to do. I created a home network, guest network, and IOT network. Still it’s not improving. Does anyone have suggestions? I’m not sure if there are more specific ways to “modify” the modem or settings? I’m good with technology but no means a modem/network guy. Thanks for any help! I recently returned my xfinity modem/router and purchased a new one. My IT Guy at work suggested the upgrade to speed up my service.I have the SB8200 modem and TP-Link - AX1800 WiFi 6 Router.I hooked everything up, but the wifi seems to be slower than before. I don’t know if something isn’t configured correctly? I’m no expert at all so any help would be appreciated. Here are the screenshots I thought might help.

connecting sb8200 to optimum

I purchased an SB8200 to connect to Optimum after having them scan the MAC address at their local office the modem will not connect. The power light is green downstream and upstream lights stay solid greed and internet light flashes green. This stays this way for several minutes then the internet turns solid green for maybe 5 seconds then all lights except power go out and the process repeats. I have had them reflash the service, confirmed the MAC address and even changed my service coax cable. I had this issue about 1-2 years ago when I upgraded a modem at another location and after much ado it was resolved but I don’t remember how it was resolved. I really feel this is an optimum side issue but any advice would be appreciated.

SB8200 two ports

I have two ports in back of my SB8200. One goes to the wifi router, working fine. Sometimes I want a “wired” connection. I tried plugging wire into the other port in the back of the cable modem, it lights green, but computer says “no internet”. I’d prefer to have the wire into the modem (more direct) than a wire into the router. How to have both ports working with one to a router and other direct to a computer? Thank you.

no internet while connecting with router on SB8200

I have an SB8200 that will work when directly connected to a computer, but when I connect it to a Linksys wireless router, it won’t connect. I ended up buying a new one, but I would like to understand if anyone else has seen this.

SB8200 Hardware Version - Bought From Amazon Arris Store

Recently purchase SB8200 off of Amazon. Checking hardware version it list Version 1. Am I correct in assuming this has been sitting around for a long while? It appeared to be in original packaging. Should I send it back and reorder in hopes of getting version 7? Send it back and order from Arris with the assumption I’d get the latest version? Not worry about it?

Xfinity Bricked My SB8200

First post, hope I’m putting this in the right place.TLDR: Xfinity activation bricked a previously activated SB8200, and their tech support told me to contact Arris for a "configuration file".****I've used a self-owned SB8200 with my Xfinity plan for 3 years, but after upgrading to the gigabit plan, Xfinity began sending me email notices that my equipment isn't capable of fully utilizing my plan.So, I bought a recommended Arris S33, swapped out the SB8200, and had the S33 activated and running in minutes. I put the SB8200 back in a box for storage, feeling it would be handy to keep around if the S33 failed in the future.Although the S33 performs just as well, if not better, it is much hotter than the SB8200. So much so, that I decided to return it to Amazon and reinstall the SB8200. (I don't like hot electronics, but that's just me....)BIG MISTAKE.....Upon swapping the S33 out for the old SB8200, I found that Xfinity's system wasn't providing any internet service (even though the fron

Router takes internet speed down by a factor of 6 (SB8200)

I upgraded my Xfinity plan from 50 Mbps to 300Mbps after purchasing an SB8200 modem.When the modem is connected directly to my computer, I get 300Mbps.When the modem is connected to my router I get the speed of my old Xfinity plan: 50Mbps.I am using two CAT5e cables, each of which, when connected directly from modem to computer get 300 Mbps. I did a hardware reset of my router with no change.My router: TP-link AC2300 Any ideas what might be going on?

SB8200 modem rebooting with error T4 timeouts

I was using a 6141 but T4 timeouts kept it rebooting. Went to the 8200 because I wasn’t getting any help with the T3/T4 problems. So, I think your just fine as long as your local Optimum network is good. I couldn’t live with the T4 timeouts and reboots. Oh … my provider is Optimum too. Not saying my 8200 is doing much better. No event log, it staggers at times, claims it is up when our connected devices say otherwise. But yeah, calling your provider for a list of supported modems is the answer.
