ARRIS SURFboard SB6190 Connection Speed Problem
This Xfinity account with a SB6190 modem is receiving significantly reduced interned speeds. This SB6190 had received 275 Mbps up until about June 2020. Customer continues to receive good upload speeds of 10 Mbps. Xfinity Technical Support believes problem may require SB6190 which will require expensive upgrade to Motorola DOCSIS 3.1 modem . Customer believes problem may be an Xfinity issue supporting SB6190 modems. (For instance, Xfinity could send a bad boot/config file causing lowers connection speeds to SB6190 modems.)
Xfinity customers with SB6190 modems please post following:
1) Xfinty internet service tier.
2) Connection speed test results from https://speedtest.xfinity.com/
3) Advise if SB6190 event log found at http://192.168.100.1/cgi-bin/eventlog contains following error messages ‘TLV-11 - unrecognized OID’ and/or ‘No Ranging Response received - T3 time-out’
4) Post your approximate location.
Here are my SB6190 results:
1) Xfinity 275 Mbps Internet Service
2) Download = 91 Mbps. Upload= 10 Mbps
3) My SB6190 event log does contain error messages ‘TLV-11 - unrecognized OID’ and/or ‘No Ranging Response received - T3 time-out’
4) St. Paul, MN

2) Download = 150 Mbps. Upload= 17 Mbps
3) TBD

Have you tried calling Arris? I would also be interested to see the solution to this as I am experiencing the same slowness since around May 2020

I also began experiencing slower speeds in the May 2020 time period. I contacted Arris and modem passed all tests. Since we have both experienced slow speeds around the same time this definitly looks like a change was made by Xfinity in this timeperiod which has slowed connections to SB6190 and possibly other modems.
1) Please at least try to post your Arris error logs to this thread. Arris error logs may be found by going to http://192.168.100.1/cgi-bin/eventlog (username=admin, password=password).
2) Please also seek a Xfinity billing credit for spending time helping Xfinity troubleshoot a problem(s) with their service.

Thanks node006565
I have to get a few things for my MAC to be able to plug into the Arris RJ45 port.
Will post logs as soon as I get them
I also just posted a support help from Arris in hopes that they can help .
I posted the log output that was posted in the original thread
I guess the question is, is your issue resolved?? If it is, what did you do to resolve this?? Would really hate to buy a new modem.

This is an ongoing problem. The SB6190 continues to have slow Xfinity Internet speeds.

My DOCSIS 3.0 modem speeds have mysteriesly been cut in half since May 2020. It's an SB6190 subscribed to 250 Mbps Xfinity with slow ~90 Mbps download (upload speed is normal)
Any others with DOCSIS 3.0 modems post https://speedtest.xfinity.com/ results to this thread to let us know if your internet speeds are as expected or slower than Xfinity subscription.

Are you connecting via Wifi or Ethernet? If Ethernet, speeds around 90 Mbps are sometimes due to cable or connector problems, or an network adapter that isn't capable of Gigabit speeds.
If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your modem or gateway's model number and signal information ("SB3160" isn't a valid model #), especially downstream power levels and SNR, upstream power levels, and error log.

SB6190 modem, SNR, and Power and upload speed is good. I've made calls to Xfinity technical support who were each capable of modem reboot, however I have not found any way to request Xfinity test their equipment to ensure it is functioning correctly.
