No Ranging Response, DHCP FAILED, B-INIT-RNG Failure

Hello, I have been having more and more issues with my Virgin Media broadband throughout the past few months. The internet completely cuts out at random times on random days for 2 to 5 minutes and then comes back up. On some times only the wifi cuts out, ethernet is still working whilst on other days both are down... Can anyone help by looking at the countless errors on my network log? I'm really not happy with the service as I pay quite a lot for it and it is not up to standard. I have the Virgin Hub 3.

Re: No Ranging Response, DHCP FAILED, B-INIT-RNG Failure

Those are undesirable errors.  As a possible cause, the upstream power looks too low unless you're in a newly installed FTTP area.  Downstream power range also looks too wide in my view.  I'll flag this for forum staff to take a look and advise.
