I have just installed my new network adapter for wireless connectivity. I am using TP-LINK TL-WN727N. I installed the drivers from the manufacturers website to get the latest version. The installation worked well but I still have problems with visiting other pages.

Using internet explorer, I cannot visit some pages including google.com. It says there is a certificate error, but when I click "continue to this website(not recomended)", it will then proceed. It shows something like this:

enter image description here

I downloaded google chrome and tried to do the same, visit google.com. It says that it cannot connect to the real www.google.com. Image is something like this

enter image description here

Some things I noticed:

  • When I hover on the wifi symbol (the one on the taskbar on the right end), it says "Identifying... Internet Access". I wonder why is this so. Normally it should say "<Router Name> Internet Access"

  • I opened network and sharing center but my computer seems to be not connected to the internet but still I can visit some pages. How can I fix this? Refer to image below: enter image description here

I am not sure of what the problem is here. I reinstalled the network adapter's drivers and I can visit some pages but not all. Both browsers say that there is a certificate error or an SSL error, and to add to that, hovering on the wifi symbol says "Identifying... Internet Access". I am pretty sure I am not being hacked because I am using a home network.

-- Update: Some ipconfig results --

Wireless LAN adapter Local Area Connection *2:
Media State: Media Disconnected
Connection-specific DNS Suffix:


Wireless LAN Adapter Wi-Fi:
Connection-specific DNS Suffix: domain.name

ping statistics are normal.

-- Some of the things I already tried --

  • Change system time to sync with the internet. I synced my time with server time.windows.com
  • Forget my home and reconnect
  • Disconnect from wifi then reconnect
  • reinstall network adapter's driver
  • cleared browser cache etc. (ctrl+shift+del)
  • reinstalled chrome

Please help me, No solution to my problem until now. I'll follow any suggestion you make.

--- Update: Already fixed some stuff but still has certificate error on both browsers --- I fixed the problem on network and sharing center. Now it displays my network. I edited the permissions under the registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList

Still, I cannot visit some pages using both iexplorer and chrome.

  • May be you need to change IP address to DHCP or to static. Not sure. Give it a try.

  • Check your system time and include a screenshot of the page.

Try to change your IP to dynamic. To do this:

  1. Open Network Connections.

  2. Select Your Adapter, right-click and select Properties (or just Alt+Enter)

  3. Select Internet Protocol Version 4 (TCP/IP)

  4. Select Automatic IP Configuration

Refer to this guide if you have problems.

  • Try pinging problematic sites.
    • Goto the start menu, type cmd.exe and hit enter.
    • Type ping <website URL here> and hit enter
    • Tell us what you see
  • Type ipconfig in another cmd.exe window. Tell us what you see.

That should get us some useful info to work with.

--------- Update 1 ----------

Now try resetting your browser cache in IE and Chrome. See if that fixes it.

  • Anything to do with Wireless LAN. Or WiFi in general. (My own is polluted with Ethernet adapters and such). Your ping results are good. I'll have to think about how to continue debugging. See updated answer.
