Lost Internet connection, ethernet "unidentified network"

[slim01]

Hi guys, really hope someone can help.
Last night all of a sudden me and Mrs had to both resign in to WiFi networks on phones. Later on the same night turned pc on, no Internet "unknown network".

-I have constant green led and occasionally orange flash at mobo end.
- I watch as I plug cable in on control panel > network and Internet > network connections >
And it shows "identifying" sometimes for 40secs or just goes straight to "unidentified network".

Shows as unidentified network
"ethernet public network"

It did work at one point tonight for 5 mins, then stopped without me changing anything.

Most of the time, problems found on windows10 diagnosis tool:
"ethernet doesn't have a valid ip configuration"
...
"investigate router or broadband modem issues - the failed
Reset the ethernet adapter - completed

Once I have also seen:
"an ethernet cable is not properly plugged in or might be broken". "plug an ethernet cable into the network adapter" but see that even when I can see the connection is there so no idea why it thinks nothing is plugged in. 2 cables tried also.

Tried...
-all ports on rear of router
-new ethernet drivers
-factory reset router
-calling virgin media
-several ethernet cables
-renaming the connection to "Vladimir Computin" (as it was before the router factory reset, as connection is still named this on the laptop)


---
In network connections I see:
Vladimir Computin
Unidentified network
Realtek PCIe GbE Family Controller
---
Status.
IPc4 connectivity - no network access
IPv6 connectivity - no network access
Media state : enabled
Speed = 1Gbps

Sent = 0 Bytes
Received = 1180 Bytes

---
Next to try...
-a copy of Windows from another ssd
-no idea

Mobo is an Asus x570-p.

Thanks in advance for any ideas guys, I'm so stressed about this one.

Do you phones connect to your router ok, or not sorry did read your post but wasn't 100% clear.

If say if your phones are having issues as well as your PC almost certainly your router.

Those things don't last forever, and you probably won't be able to fix it.

Yeah the Mrs and I both had to put password in again on phones but connected right away with no issues. My laptop also connects over WiFi or ethernet. Will update post now sorry for being unclear my fault.

If the error message is correct, it's strange the router assigns an ip address to the laptop but not the HTPC... You think it could be a faulty router even in that scenario right?

Thanks for help. Really appreciate it honestly after the year I've had. Bike don't work, gaming pc, new oled is going back also as monitor mode not usable at all

These things happen.

You know it would be worth a go, ringing your ISP and see if they can sort you a new router.

I'm with Zen internet, to be fair been a customer since 2008, but couple of years ago I was having wierd issues with my router they sent me a really high quality Fritz box router completely free of charge.

It's worth an ask, and if they do send one it I'll knock one possibility off the list.

The fact your phones played up at the same time though, especially if you were not messing with anything, it's almost certainly the router. They don't last forever those things.

Yeah not even a year old, but I guess even new parts turn up screwed.

I rekkon they'll say well working on the laptop it's not the router it's pc.

I'm not gonna mention the laptop this time, as you say if they send another, it's one other thing off the list

 

[slim01]

Virgin have said they're gonna sent an engineer sent out now... They confirmed it won't cost anything on this occasion but yeah I'll try fix tonight as I'm not entirely sure it's the router either and don't wanna waste anyone's time tbh.

I have another ssd with a working copy of windows on it, I'm gonna try on that, settings should be bang on on that ssd?

 

[slim01]

If the laptop works
Connected with same ethernet cable
On same ethernet port on router
Routers probably fine
A lot of the time it's because windows stupidly ticks
Turn off this device to save power
So I would look in device manager then network adapter
Then power management
And make sure it hasn't ticked the save power boxes/options

OK I unticked that box (it was set to save power) but no change... Damn

Something seriously wrong with this computer... I swear it's toying with me and wants me to smash it in. It's now stuck in flight mode. Flight mode.... On a bloody desktop?!?
It's also booted a few times with constant blue load circle, and taskbar not clickable;
I think the bios update might be screwed you know as it did the same thing several times on a new new test rig (bought another asus x570-p). The reason I got the test rig was after I "upgraded" my cpu/gpu - and the bios for new cpu, I had graphical issues which may or may not be in my head. Wish I would have left the damn thing alone.

Thought I fixed it earlier, randomly plugging cables in and out and it connected to "network 5" which I've never heard of.
Was working fine until I noticed games were taking ages to update - checked and download speed 1.4mbps. 11mpbs upload?
My phone has 120mbps download and also 11mbps upload over WiFi. Laptop the same roughly (ethernet).

Restarted router, touched NOTHING, and again, "unidentified network" shows.

I cancelled the virgin engineer coming out tomorrow as to not waste his time thinking it was fixed... Damn.

Will try some of the above suggestions now. Once I get the damn flight mode off.

One other thing to note guys, it's impossible to uninstall the ethernet driver. From device manager I uninstall it, refresh the list, and it pops back up again. Is that normal?

I have never touched Ubuntu is worth the I'm guessing 3-4 hours it'll take me to learn how to use or pretty straight forward? Thanks

 

[slim01]

Just disabled "radio management services" and flight mode is still active... Can't get rid of the symbol... And now it IS connected to the internet once more. Again this time, about 7mbps.

Not sure if I should go messing around with anything now and just call virgin tomorrow.

 

[slim01]

Yeah windows may just reinstall it
Ubuntu for your needs is a doddle
Simply choose run as live
Or whatever the exact terminology is
IE not the install option
Then just open the web browser
No need to do anything complicated with it

Edit
Believe it has Firefox pre installed

Edit 2
If you don't want windows to reinstall it
So you can install a specific driver etc
After uninstalling it
Don't refresh/scan for hardware changes
Just go install the driver you want

Will try this tomorrow... Thanks so much for help.

 

[slim01]

11mbps were going up!

 

[slim01]

Did you Restart the pc after doing it?
And yes if got another SSD with windows
Always worth trying that to rule out
Software or driver issues
Another option is roll back the driver in device manager
If there's a possibility a driver update caused any issues

Edit
Can also look to see if
Obtain IP address automatically
Obtain DNS server automatically
Are selected in ipv4 settings in properties of ethernet adapter

If that doesn't work from elevated command prompt enter
Netsh winsock reset
Netsh int IP reset
Then restart pc

Tried the following, no change.

Can you try "ipconfig /all" from an elevated command prompt? What are the IPV4, Subnet & Default Gateway results for your ethernet adapter?

Sounds like you're not getting assigned an IP, unless you're already using a static.

I will post a pic for you now after uploading online.



One thing to note guys, pretty sure I'm on to something here...
-if I connect router (virgin hub3.0) to a 4port switch Then switch to my pc, I get Internet connection instantly, however it is only rated to 10Mbps when I go to connection properties from task manager > performance > ethernet (right click) > view network details

My dl speeds are ranging from 3Mbps to 9.5Mbps, but upload speeds are normal at around 10Mbps. The switch is rated to 10/100Mbps

Ive tried change adapter options (right click ethernet 5) > properties > configure > advanced and from there tried changing loads of options, including changing "speed and duplex" to 1.0 Gbps full duplex (as opposed to auto negotiation).

The link speed then changes to 1Gbps until the connection comes back then it goes back to 10Mbps.


-I have a little £6 wifi adapter I just got, gonna try that now.
-virgin engineer coming on Tues.
- Wednesday I should have a used virgin hub 3.0 replacement (got for £10), as virgin refused me a new unit.
-I also have a USB 3.0 to ethernet adapter turning up soon, I wonder what that will do. If that don't work I'm gonna guess the router is at fault.
-also considering buying a proper TP-Link router and setting the virgin hub to modem mode, as advised by a mate. Don't really want loads of routers and cables everywhere though

Here is pic from ipconfig

Edit.... It's working!

I thought I'd take off the switch, wire directly into the hub one last time before trying new ssd / Ubuntu and it works, full 120mbps. Flight mode is still there. Might just ignore that.

Hopefully it stays this way!

Perhaps this from mcnumpty did actually work just took a couple of restarts?
"If that doesn't work from elevated command prompt enter
Netsh winsock reset
Netsh int IP reset
Then restart pc"

Thanks guys, fingers crossed its done...

@slim01 Is that the Ethernet connection you got working or Wi-Fi ?

Having the same problem with my Ethernet but works fine with Wi-Fi.

Ahhhhhh man I feel for you. Try doing the above cmd thing as administrator. Unless it fixed itself then it was that.

Working with ethernet. I haven't even tried the WiFi dongle yet but will probs keep around, and the spare virgin hub, just to try if it fails again.

Do you get a speed limited to 10Mbps or nothing at all? You got the airplane mode too?

 

[slim01]

Nothing on the Ethernet but usb wifi dongle works fine though I havnt run any speed tests so will check.

Well if it's not connected at all you won't be able to run a speed test at all... What does connection say, "unidentified network"? And diagnosis tool states no valid ip configured?

Ok so I almost, VERY almost threw my xbox controller at my brand new £1000 oled (which is also being a pain in the backside) after I finally got everything set up to game last night...

Snacks ready, Mrs in bed, the riftbreaker all loaded up (game I've waited for for ages) aaaaaaaand can't connect xbox controller to pc (using the wireless official xbox adapter).

Plugged it in the laptop... Works first time. W... T... F....

I'm wondering if some settings I've changed.

Also... Flight mode has come back. Could be the issue but can't for the life of me turn it off. I even got a WiFi adapter, so got WiFi on pc, finally had the actual option to turn it off, but when I unplug the wireless receiver, so ethernet only, flight mode bug is back, its always on (but Internet works).

I'm thinking I need to do a windows reinstall after the settings I've changed

 

[slim01]

I'm ment speed testing the Wi-Fi connection to check getting full speeds.

Ethernet is exactly that unidentified network and no valid ip.

Only started when we switch providers went from virgin to sky.

Issue is I'm not even sure what fixed my issue, I'm not even convinced it's something I did so maybe issue with router or windows bug.

Couple of work arounds though...
1) get a USB ethernet adapter
2) get a decent WiFi adapter
3) get a new router and set virgin/sky router to modem only mode, at least then you know you have a decent router. Tp vision ones on amazon are on offer for 40 quid or 45 quid for like +500Mbps WiFi and giga ethernet. They also seem to go on auction used for around £10 - £20

I might buy one anyway now in case it happens again
