Browsers not working, internet connection is fine

I just had this exact same problem; flushing dns and resetting Winsock (??) fixed it. Diagnostic was Windows diagnostics reported NO PROBLEM; ping, nslookup all worked fine. Network Sharing reported all good. No browsers worked. Diagnostic ? other net clients worked. I was using OpenDNS, but I don't think that was the problem. Up and down the internet stack, chrome, firefox, did not work. The network diagnostics are just not working properly. The key was chrome has really cool diagnostics and it was reporting DNS failures, not internet failures. But than typing ip addresses into the browsers address line should have worked. It did not. It was something more than a DNS failure. As our software gets overbuilt, we can expert more bizarre software failures. The windows network stack is overbuilt.
The diagnostics don't diagnose. The failures are in the TCP/ip stack somewhere.

Thankyou so much A Guy! I had the same problem as Gabby. Followed your instructions (2nd part as first didn't fix the problem) and Bingo, browsers working!!

Two years later but I'm very happy I found this forum.

Thanks again:)

I think the problem was a proxy failure; perhaps someone with more insight can respond with more authority.
There was an issue of identifying a network to connect to, not just a network adapter. In abstracting to too many levels,
the system shatters for unknown reasons. I had to flush the dns, reset the winsock, and reset networking in netsh.

This problem just started today. I was browsing just fine early this afternoon but all of a sudden i couldn't connect to any websites at all. I've tried all my other browsers too. IE, Firefox, Chrome but none of them are working. The only site i was able to open is this forum. I know my internet connection is fine because utorrent is working. Any ideas? Thanks.

first uninstall your browsers -than uninstall Flash Player - than reinstall your browsers
it will work properly

Hi, my laptop has the same problem; I only have Internet Explorer and Mozilla Firefox and neither is connecting to the internet. I have tried the solutions you suggested above, but it didn't work for me

Did you try by reinstalling ?

A bit late to the party, but I wanted to add my 2c here. This one has taken me several hours to work out.

In my case the issue was on an HP ProBook 4530s running Window 7 Professional (64-bit). All Windows and HP driver updates installed.

Despite being connected to the Internet (whether via Ethernet or WiFi) I couldn't browse webpages. Booting into Safe Mode with Networking, I could browse the Internet just fine.

Also when connected via Ethernet or WiFi, the nonpaged RAM usage would climb to over 6GB of the 8GB total available RAM. Eventually the laptop would become slow and non-responsive with various memory errors, inability to shutdown or reboot.

I tried various steps including driver updates for the network adapters, uninstalling and reinstalling, flushdns, winsock resets as recommended elsewhere. None of which worked in my case. I also ran Malwarebytes and AdwCleaner in case some malware or browsed hijackers snuck onto the system, but nothing was picked up.

I had in-mind that ESET Smart Security (AntiVirus and Firewall) could have been getting in the way, and it had been updated to the latest version recently which reinforced that theory. I went ahead and uninstalled ESET SmartSecurity, rebooted, downloaded and reinstalled the latest version (10.1.219.0 as I type) then rebooted to finish.

Browsers are happy again and no ramping up of nonpages RAM usage, so I think that we're good to go.

HTH someone out there save a little time.

Hello, I'm having the same problem with my browser its not connecting...and I have tried the cmd process as explained, yet its not connecting...and when I run the window network diagnostic... It's said "the device or resource (http://www.facebook.com) is not set up to accept connections on port 'HTTP' "

Hi Olu, It may be better to start a new thread as this is an old one, so someone will spot it easier. Could

you use the link below to fill out your system specs please, also what browsers you are using, and antivirus.
