No Ranging Response received - T3 time-out

Hi I am having issues with my internet and the network log is showing all kinds of issues. I have tried factory resetting router and checked the cables are in properly but hasn't worked. I have had VM try to help me over the texting app but that didn't work either. My wife uses our broadband for work. I have a Hub 3.0.

      Power levels look spot on.  Can we check… are your issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check on one to help diagnose whether it is just a wifi issue or it could be network connection/Hub related?  What are the Hub lights showing/doing when you get the issue.

      Then can you start from a clean sheet by doing this...

      ___________________________________________

      Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing. When its light, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables.

      Then switch the Hub back on and leave ~5 minutes When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.

      Also check the Upstream QAM’s are all at 64 - if they are dropping (to 32/16) then you have an issue

      Also, If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

      Can you start from a clean sheet and do this....

    Thank you for your reply, I have done what you said about clearing the T3 time outs they are all set to 0 and I will monitor them going forward, I have also set up a BQM for my internet as well which I will also keep an eye on. 

    Unfortunately I don't have any ethernet cables in the house to test but I will get my hands on one and test it on my wife's laptop to see if it has any issues. 

     

    No issues with any cables inside or outside the house that I could see. 

     

    Thank you again.

      OK good  - also keep your eye on PostRS errors... they shouldn't be appearing at all too.
