Windows 10: Unidentified network - No Internet access

Currently, my PC can't connect to the internet through the LAN. The LAN says "unidentified network". However, the PC can connect to the internet through WiFi (but very poor connection).

I have a PC that runs on Window 10 Home. And, in the middle of internet browsing, my internet connection was lost.

My PC sometimes lose internet connection, and it is either the router's or poweline adapter's problem. But this time, the router is functioning, cause my phone & PC can access the internet through its WiFi. And, even when I switched to another powerline adapter and ethernet cable, it still can't connect to internet through LAN. So, I am not quite sure what's happening at the moment...

I have ran the 'window network diagnostics'. And it stated this : "Local Area Connection" doesn't have a valid IP configuration.

I'd rather have LAN than WiFi, because I need really good internet connection for my online education classes.

So any ideas?

Thanks

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.)?

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?

 

Make sure, you have updated LAN driver. You can use Driver Easy Free.

Have you tried Network reset?

Additionally, you can try to reset you network like this. Download WN.bat and run it as admin, then restart.
