PC suddenly will not connect to internet either via ethernet or wifi

(When referring to being able to connect to wifi or ethernet I mean connect and use the internet via that method)

Started yesterday afternoon with broadband just going down completely. I tried rebooting the pc, unplugging the hub and hard reset of the hub and nothing worked.

My pc will connect to the internet via a wifi hotspot on my phone or via mifi device no problem, so I know the wifi card is working ok.

Waited ages for CS to answer and while going through the same process with them yet again (running up and down the stairs) the wifi for my smart tv and firestick started working again. However the ethernet and wifi for my pc were still out. My phone also connected to VM wifi no problem. However pc still unable to access internet on either connection.

Finally did yet another hard reset as requested by CS which cut us off (wonderful digital landline) and she did not ring me back. Great customer service. This hard reset knocked out the wifi connection to all devices again.

I rang back and went through the explanation with another CS agent who came back and said he had discovered an intermittent issue and it would be monitored for 24 hrs before deciding if an engineer call out was required.

Doing a service check sometimes got the same message, but most of the time got an "everything is fine" response.

Had to use the personal wifi hotspot for most of the evening but later the firestick wifi started working again.

This morning the pc was also able to connect via wifi but not via ethernet. Wanting to have the wired connection I rebooted the pc hoping this would work, only for it to once again not be able to connect with either ethernet or wifi.

It has remained the same all day.

I got the text this afternoon from VM saying they'd been monitoring and there was no problem found.

Everything remains the same now. My smart tv seems to be running normal speed over wifi as does my phone.

My pc will not provide internet via either wifi or ethernet. My pc connects to any other wifi connections' internet without issue.

I've just tried to connect a Samsung tablet which hasn't been switched on for a few days and the internet is timing out.*

Doing a service check on the VM website just now shows no issues found.

However there is very obviously an issue.

I checked the hub settings (hub 3) and there are no paused devices or anything showing which might be an issue.

*While typing up this message the Samsung tablet suddenly started working on the VM wifi but then 30 seconds later started timing out again.

Does this sound like I need a new hub?

A Hub fault is always possible.
A signal fault issue could also give the impression of a Hub fault.

Take a look in the Hub menu as the stats for the Downstream and Upstream connections.
Are the power levels / numbers of channels etc with in the expected norms ?

  I can't make head nor tail of the upstream/downstream stats - I've no idea what the expected norms are.
  
  There's a lot of critical/error/warning messages in the network activity log going back to the 23rd
  
  No ranging response received/DHCP renew warning - field invalid in response/RCS partial service etc
  
  Is this pertinent?

Copy and paste the text from the Upstream and Downstream stats into this thread for review.

A smattering of errors on the Downstream, but in general the connection stats look fine.

I'm borrowing a laptop from my brother in law to test it's ability to connect to both LAN and wifi but can't get it until tomorrow.
Just to try everything I set up a guest network in the hub and the pc connected without issue. Currently getting 350+Mb/s. Will monitor over the afternoon.

No.
I called CS again on Friday and got through to the upper level (said they had more power than the regular agents). They noted that my router had not been updated since March and sent updates, had me power off and on but still no joy so they booked an engineer fro Saturday.
As soon as I explained what was happening to the engineer he said it sounded like the router.
He replaced it with a Hub 5 and everything has been working fine since then.
Thanks to those that offered advice.
