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

[gsh68]

(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?

do you have HomePlug - Network Via Mains?

[gsh68]

No it's a TP-Link WiFi Extender.

Is this what you asked for?

Seems you can't DHCP maybe hub is bad.

You can add a static IP in windows like 192.168.0.77 subnet 255.255.255.0 gateway 192.168.0.1 DNS 194.168.4.100 and 194.168.8.100

Sounds like VM are as a stupid about asking a customer on a Hub hosted landline to reboot the VM Hub as Talk Talk are about asking their customers to remove the BT faceplates mid support call ... makes it easy to instantly close the call with customer hung up on me.

"Autoconfiguration IPv4 Address. . : 169.254.97.141(Preferred)"

This is what we see when a Windows computer has failed to get a DHCP response and has allocated a default IP
( an IP that does not result in a working connection ).

When you look at the VM Hub 3 does it have a white bar as the only LED showing, indicating it is online ?

if you can login to the Hub 3 menu, check if the DHCP server is enabled this is at  :

( Hub 3 menu ) >>> Advanced settings >>> DHCP

Our ( working ) Hub 3 settings look like this screen shot ...

Yes, just a static white bar.

Mine looks exactly the same.

Your computer looks like it does not make contact with or get a response from the VM Hub.

To loose both Wi-Fi and Ethernet connections on my laptop I'd have to select Airline mode.

[gsh68]

No, airline/flight mode is not on.

So does it sound like the hub may be bad? Bearing in mind 1.that even with other devices that do/can connect to the internet they have varying speeds and don't always get internet access, 2. the pc settings were not changed before this issue?

[Client62]

I'd be focused on the computer, and that is based based on the original comment of ...

"My smart tv seems to be running normal speed over wifi as does my phone."

[gsh68]

Why would both ethernet and wifi go down on the pc at the same time? They are separate bits of hardware. I didn't change any settings.

The pc being able to connect to other wifi networks without issue would suggest there's nothing wrong with the actual wifi card.

Not all devices are able to access the internet via wifi.

The internet connection over wifi has been random since this started - some devices can connect, some can't. A little later the same device will be able to connect.

Speed varies between devices sitting next to each other. My phone is actually only showing c.47Mb/s on ookla now, when it showed 140+ Sunday.

Any suggestions on what to check now? Should I do a network reset?

Thanks for your help so far - I'm at a loss over here.
