Critical Errors - ‘No Ranging Response received - T3 time-out‘

Kevfter

Hi,

My home Wi-Fi signal keeps dropping intermittently.

I work from home, and I got disconnected from a Microsoft Teams call 3 times. This is a lot as the call was only about 30 minutes in total. When I am disconnected from the Wi-Fi, I get a 'No internet' message on the network icon in the taskbar on my laptop. It takes a few tries to reconnect.

I have tried soft rebooting, switching it off at the power socket, and factory resetting the router several times, but it does not seem to help. We shouldn't have to keep resetting the router so frequently to get back on the wi-fi.

I am getting a Critical Errors - ‘No Ranging Response received - T3 time-out‘, 'DHCP renew' notice errors and a 'RCS partial Service' Warnings showing in the network log on the router. I have provided a screenshot of this and the BQM graph below. I have the VM Hub 3 which is an old router. Is there a way to export or download the network log from these routers so I can share this with you?

DHCP Renew - lease parameters tftp file-cmreg-vmdg505-bbt062+voc-b.cm modified;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

RCS Partial Service;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

Please let me know if you need more information form me and if you can investigate and hopefully fix this issue. I have seen others that have posted these errors on this forum already.

Thanks,

Kevin

MS Teams is frail at the best of times.  We just do not read the same grips about Zoom or Webex.

If possible, use a network cable.  For an ultra slim laptop, a USB 3/C to 10/100/1000 network adaptor too.

Try these Wi-Fi settings, the goal is to prevent the Hub 3 from randomly dropping WI-Fi during Wi-Fi channel changes ...

It appears your issues aren’t as a result of MS Teams specifically - the RCS Partial Service errors would indicate an issue with the connection itself

In terms of the logs - you can just copy and paste them, but will need to do it twice (error will occur the first time, but second time it will post)

Once you’ve posted them, it may take a few days but one of the Forum Team will probably reach out to book a technician visit.

Hi Client62 and RT123,

Thanks for both your responses.

I will try changing the Wireless settings you suggested.

Please find my routers network logs pasted below. I lost internet connection tonight, so if the forum team can analyse the logs and book a technician visit that would be great.

Thanks

The Hub log contains the same kind of entries we see from our Hub 3 & we have a good service.

The content of the Downstream & Upstream tabs is usually more informative as we can see if the signal levels are outside of the preferred range or Post RS Errors are present and continuing to increase.

And could you please post the logs again if the number of PostRS errors is still rising? There’s a lot of PostRS errors in some of the channels.

Hi,

That's me lost wi-fi access again already this morning. I am getting the same error messages as before. Either 'Your not connected' or 'No internet'. Please find the network log, and downstream and upstream logs below. The network log is showing the error message again: - Critical Errors - ‘No Ranging Response received - T3 time-out‘.  I can send you the BQM graph for today too, if that helps?: -
