There’s not a lot you can do nowadays without a solid internet connection, which is why problems like this one are so frustrating.
We’ve all been there: your WiFi router shows something like “No Internet Access” or “Limited Connectivity”, likely when you’re doing something important online, and you feel like you want to smash in your computer with a baseball bat.
Re-install the Network Adapter Drivers or Update Driver Software
In some cases, simply switching back to an older version of the Network Adapter settings is enough to solve the issue. That’s why the first thing you should do is try to restore your network drivers to some older version, or even revert them to the default manufacturer drivers instead of the ones suggested by Windows 8.
And here is how you do it:
Open Device Manager Method 1
Press the [Win] key and the [X] key simultaneously.
Open Device Manager Method 2
If you updated to Windows 8.1 or later, simply right-clicking on the Start button will do it.
Open Device Manager Method 3
– Go to the lower left corner of your desktop with your mouse. At this point, a transparent menu should appear. Go up and click on the gear icon Settings.
– When you click on the settings a dark blue menu should appear. Now click on the Control Panel
– After the Control Panel appears, you might want to change View to Small Icons
– Find and click on the Device manager icon
– When in Device Manager, find you Network Adapters and expand them
– From the list which has appeared before you, choose the Network Adapter or Wireless Network Adapter that’s showing the limited connectivity issue
– Right-click on the (wireless) network adapter and select Update Driver Software
– A new window should now open, at which point you click on Browse my computer for driver software
– Click on Let me pick from a list of device drivers on my computer
– Review the Network Adapters – it’s possible there are two or more drivers there, one by Microsoft and one by the manufacturer
– Select the manufacturer’s drivers and hit Next
– You will be asked to restart your computer. After performing this step, see if the problem has been solved. If not, proceed with the next step.
Address the network problem with TCP Command Lines
– Open Command prompt as administrator (to do this, type “cmd” in Search, right-click the icon and select Run as Administrator)
– Once you’re in the administrator console, enter the following three command lines, hitting Enter after writing every command:
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
– You will be asked to restart your computer. After doing this, the problem should be solved.
Problem with – Can’t turn wireless capability on?
Check if you have installed your wireless adapter’s latest drivers. If you still can’t turn on wireless, press [Fn]+[F2] and proceed to the next part of the process.
Your wireless adapter is turned off by a hardware switch. Look around all sides of your laptop – you should see a small switch on the left or on the back of the device which enables and disables the wireless capability.
Now try pressing the [Fn]+[F2] combination again.
Limited Connectivity Virus!
There are viruses which can hook or damage your wireless network drivers. Other malicious pieces of software can break the LSP chain by replacing a legitimate DLL with a patched one. Scan your computer to ensure there isn’t any malware infecting your system!
