Somehow, Windows no longer detects my Internet connection and I have no idea why (and I'm a tech). :smash:
(I checked the following link here, but it didn't resolve my situation.)

 

To make matters worse, I restored my PC from a backup made TWO MONTHS AGO and I still can't get online!

 

Hardware is fine. I'm using it now (dual boot PC with Ubuntu Linux), and another computer connects to the Internet via WiFi with no problem. I've tried three different browsers (Firefox, IE, Chrome), my email app & FTP software. Nothing connects. Nor does any software capable of online updates.

 

This computer is connected to the router using an Ethernet cable, but I've tried bypassing the router and connecting my DSL modem directly, but it made no difference. The problem has all the hallmarks of damage following the removal of some malicious AdWare/Spyware, only that I didn't remove anything recently.

 

I've run the Network Trouble Shooter multiple times, but it only reports it can't fix the problem. I've done a full AV scan (using Avast) but it reports everything is fine as does the System File Checker ("SFC").

 

I can't connect using "Safe Mode with Networking" either. Logging into the router, I can ping "www.microsoft.com" with no trouble, but "ping www.microsoft.com" from the command prompt totally fails.

 

Out of curiosity, I tried plugging a WiFi adapter into my PC and it (the adapter) sees my connection with 4-out-of-4 bars solid green, yet I still can't connect.

 

I'm stumped. Anyone? Please help!

I quickly scanned through the thread you linked to but I didn't see anything about resetting Winsock or TCP/IP.

 

Type CMD in the Search Box, right click and select Run as Administrator. At the command prompt type

netsh winsock reset
netsh int ip reset c:\resetlog.txt

Reboot.

Thanks for the fast reply.

 

I don't know how or why, but right after posting that, I rebooted into Windows and everything is working fine again! Damn thing hasn't worked since March 30th, but now suddenly, without explanation, it is suddenly working again??? :scratchhead:

 

I really would have liked to try your suggestion. It would have been interesting to know if that was all I needed to do.

 

The last thing I did trying to get my computer working again was reinstall my last backup, but after a reboot, it still didn't work. I then tried unchecking every (non-MS) Startup App & Service using "msconfig" and rebooting, but that failed, so I put everything back, rebooted, still didn't work, so I booted into Linux to post my question.

 

And now, suddenly, everything is working again. :smash:

 

I'm too relieved the problem fixed itself to be angry at the insanity of it all.

 

Thanks.

Thanks for the update. Glad your problem resolved itself. Those are the best fixes. I also have a computer that dual boots with Ubuntu but it's an old AMD XP Athlon running XP. 

 

Never had an issue with Ubuntu.
