Windows 10: Unidentified Network/No internet access

Hi all,

Today has been rough for me since about 10am this morning. I have a PC that I built about 10 years ago that qualified for upgrade to Windows 10 about 5 months ago and until this time, I've had internet access on my PC. I've had some blue screens that occurred a few times a week due to sporadic issues with a windows driver for my NVIDIA graphics card - I found that NVIDIA has no drivers for Windows 10, so I'm stuck with that windows driver. I started my PC this morning to work on some emails at 8:00am and things worked absolutely fine. Than about 10:00am, I had a blue screen "page fault in nonpaged area" - this has happened before, but Windows always recovered without any real harm.

The PC rebooted and then I found I had no internet. I looked at the icon on the toolbar and it had the yellow triangle "!" on it with "unidentified network - no internet access" So I checked my router - a Motorola Surfboard - all the icons were lit, so I checked my laptop(I'm using a laptop now for this) and it was still online without issues. Both my PC and laptop are connected via ethernet cables. I looked on the back of my modem and the port that my PC was connected to was lit - so communication was going on there.

I tried the windows diagnostics - it found no problems. I opened the network and sharing center and it shows "unidentified network - Public network" For access type: No Access - For Connections: Ethernet

Back at about 2pm, I found the "fix network connection issues" on microsoft's site and went into command prompt as administrator - and typed: netsh wlan show wlanreport. It said it generated a report, but when I looked for it, it did not exist. I continued by resetting the IP, DNS, and renewing the IP - of course, it could not renew my IP without internet connection. I reset the DNS, WinSock, etc and rebooted - did not change anything except now I don't have a Primary DNS Suffix or Default Gateway under IP CONFIG/All

I uninstalled the driver and network card, rebooted and it did not change anything, so I shut down my PC - obviously unhappy and flustered. Fast forward to 8:30pm this evening, I tried netsh wlan show wlanreport. again and this time when I looked up where the report was supposed to be, it was there.

Oddly, the first box on the Wlan Report has "no events from the past 48 hours to display" on it - how? I had internet yesterday and this morning!

User Info showed: Username: TED - User Domain: TED-PC - User DNS Domain: unknown

I obviously have no idea how to read a Wlan Report to find problems and diagnose how to fix, but I found it weird that under "Summary" the first box had 0 successes, failures or warnings

Under Wireless Sessions, it showed several events like WLAN Autoconfig Has successfully started/Stopped, CDE reported an L2 adapter arrival/removal

Then at 20:00:30 it shows my operating system started(after the crash) followed by 20:01:11 it says CDE reported an L2 adapter arrival - followed by 20:01:12 WLAN Autoconfig service has successfully started - then at 20:05:25 it says CDE reported an L2 Adapter Removal

20:06:18 CDE reported an L2 adapter arrival
20:06:51 CDE Reported an L2 adapter removal
20:06:52 CDE reported an L2 Adapter arrival
20:07:07 CDE Reported an L2 adapter removal
20:08:14 CDE reported an L2 adapter arrival

So this is where I stand now - Ethernet status: IPv4 & IPv6 Connectivity both state: No Connectivity

I am hoping someone here can get this problem solved for me so I can get my main PC back connected to the internet!

Thank you - if you need information, tell me how to get it and I'll try to get it!

Unidentified Network, no internet access

Please answer ALL of the following [admittedly tedious] diagnostic questions by number, preferably without quoting my post:

1a. When (approx. date) did you purchase the computer?

1b. Where or from whom did you purchase the computer?

1c. Was the computer sold to you as a brand-new, never-been-used-by-anyone-else computer or as a used (refurbished) computer?

2. Did the computer come with Win10 preinstalled, did you do a clean install of Win10, or did you upgrade a Win7 computer or a Win8.1 computer [<=PICK ONE!] to Win10?

3. Who manufactured the computer (e.g., Dell; HP; Acer; Lenovo; ASUS)?

4. When (approx. date) did the problem start (e.g., as soon as you got the computer home from the shop; after installing KB4048953 on or shortly after 14 November 2017)?

5. What installation media did the shop use to get Win10 installed on the new SSD?

6a. What, if any, third-party anti-virus application or security suite (i.e., not Windows Defender) might be installed?

6b. What, if any, third-party anti-malware application(s) (i.e., not Windows Defender) might be installed?

6c. Is Trusteer Rapport installed? [If you don't know what it is, chances are it's not installed.]

7. Has a Norton application or a McAfee application EVER been installed on the computer since you bought it?

8. Have you ever run the Norton Removal Tool and/or the McAfee Consumer Products Removal Tool?

9. Are you in the habit of using "registry cleaners" (e.g., Avast Cleanup AKA CCleaner's registry cleaner component; Registry Mechanic; System Mechanic; RegCure; RegClean Pro; Advanced SystemCare; Total System Care; Advanced System Optimizer; Comodo System
Cleaner; Glary Utilities; Registry Booster; McAfee QuickClean; AVG Quick Clean; AVG PC TuneUp; Norton Registry Cleaner; Norton PC Tuneup; PCTools Optimiser; SpeedUpMyPC; FixMyPC; PC Doctor; TuneUp Utilities; WinMaximizer; WinSweeper; Wise Care 365; Wise Cleaner;
Bitdefender OneClick Optimizer; etc.)?

Marking one or more replies as ANSWER at any point will officially close your thread (and stop the email alerts). HELPFUL votes very much appreciated at anytime. Thank you.

 

Unidentified Network, no internet access

I have tried using a USB add-on device, but when installing the drivers, I get a Bsod saying Driver_page_fault_beyond_end_of_allocation saying that rtwlanu.sys. I can still connect to my wifi without the driver, but it no internet access. Any advice?

 

10 year old hardware should work. It is most likely that your onboard NIC chipset went bad. Try another adapter.

 

I got my computer back online by doing a Windows Restore from about 8 days ago. Then even after that, I had a 0xc000021a error during the restart process that kept happening for about 30 minutes before I shut down, unplugged my computer from the wall and hit the power button to drain power left over, then plugged it back in and started it up. It did the trick, although the boot time was lagging significantly. Once Windows finally got loaded, I did a SFC scan through Command Prompt which found no issues. I am lost for words, but am grateful to have my main PC back online!

 

What does Who Crashed show? With the older NVidia GPU's, people have had to go get new cards. My father was one of them for a Intel Core 2 Duo that did not have onboard APU/CPU/GU. Go into System in Control Panel and then on the Hardware tab, make sure that it is set to 'No' for Windows update to not install new drivers. Also you should be able to go into updates and set the system to Defer updates, along with letting you choose to reboot or not.

I have not tried Anniversary on one of the test bench machines that I have downstairs. I really should on the Tower that was my dad's, until he just got a Off Lease unit that is newer.
