No Ranging Response received T3 timeout

[nickdems]

Hi all,

I saw a few other people also have report T3 timeout issues, but here's my thread as I have a different setup. 
I had a similar issue earlier in the year when VM moved to 100+mbps upload (raised here ).

I've been having issues recently with my internet dropping constantly every single day for the past couple weeks. The only way to fix it is to reboot the Hub4 modem, otherwise the internet is never restored!

I have the Gig1 package, and use the Hub4 in modem only mode (i tried router mode but also kept dying and taking the whole LAN with it - no thanks). As mentioned, the internet keeps dropping and i've tried reducing the number of external connections i made, but it still is just a matter of time before it fails. The modem is connected with a short 1m cable to the box in the wall.

When i last checked there were no faults in the post code checker.

Please let me know if i can provide anything more from my side, I have pasted them as plain text below

Thank you,
Nick

Hi @nickdems, 

Thank you for your post and for posting your stats, I have checked and there are some issues in your downstream that would require a tech. I will pop you over a PM to get this booked. Keep an eye out for the little envelope 👀📩
Thanks,
