If you’re running Windows 8 or recently
upgraded, you might have run into some frustrating WiFi issues. Windows 8
is inherently a different beast than previous versions of Windows and
with it comes a new set of problems. I never encountered too many
wireless problems in Windows 7, but have run into several with Windows
8.
In this article, we’ll go through a couple of the most common
problems with WiFi connections in Windows 8 and how to troubleshoot
them. Most of the problems occur with those computers that got upgraded
from Windows XP or Windows 7 to Windows 8. Either the driver is out of
date or the adapter gets disabled or something odd like that. Let’s get
started.
Limited Connectivity Message
If you’re getting that annoying limited connectivity message in your
task bar in Windows 8, it’s really hard to tell what the problem is. You
basically just have to try a couple of things and hope one works. The
cause could be anything from the network adapter to the wireless router
to a bad network cable. I’m only going to mention a few of the major
reasons here, but scroll down to the Other Troubleshooting Tips section
if none of these fix your problem.
Method 1 – Troubleshooter
The first thing you can try is to run a couple of the network
troubleshooters built into Windows 8. A lot of the time, it can solve
your wireless or Internet problem for you. To open the troubleshooter,
open the search charm and type in
troubleshooting. Then click on Troubleshooting, the first option.

Now you want to click on
Network and Internet.

Finally, you will see the different troubleshooters available for
fixing wireless and Internet problems. The ones you will want to run are
Internet Connections and
Network Adapter.
Method 2 – Reset TCP/IP in Windows 8
You might also get a message like this when running the troubleshooter:
WiFi does not have a valid ip configuration
In this case, you can reset the TCP/IP stack and Winsock and see if
that works. To do this, again open the search charm and type in
command prompt. On the first listing, right-click and choose
Run as Administrator.

At the command prompt, type in the following two commands, one at a time and make sure to press Enter after each one:
netsh winsock reset catalog
netsh int ip reset c:\resetlog.txt

Hopefully, your wireless connection is working at this point. If not,
skip down to the bottom section which has more troubleshooting tips.
WiFi is Disabled or Greyed Out
in one odd case, I had a Surface tablet where the wireless was
disabled and I could not even enable it. For some odd reason, the On/Off
toggle switch for Wireless Devices was greyed out like below:

The first thing you can do is try to diagnose the connection. To do
this, open Network and Sharing Center. You can simply right-click on the
network icon in the task bar and choose it or you can open the search
charm and type it in there.

Now find the wireless connection at the top and click on the blue link:

A new dialog will pop up and here you’ll see there is a
Diagnose button. Go ahead and click on that and let Windows try to fix it for you.

The next thing you can try is to restart in Safe Mode, Network
Enabled and try to turn on the Wireless there. For some reason on
certain computers, the option is not greyed out in safe mode, so you
might be able to enable it there and then restart in normally. Read my
previous post on how to
boot Windows 8 into safe mode.
The other thing you can try is to disable and then re-enable the
wireless network adapter. Again, open Network and Sharing Center and
then click on the Change adapter settings link at the left. You can see
it in the second screenshot above this paragraph.

Right-click on the wireless network adapter (not the Ethernet one like shown above) and then click on
Disable.
Once it’s disabled, go ahead and right-click again and then choose
Enable. Now try to go to Wireless in PC Settings again and see if you
can enable WiFi.
If this doesn’t work, again drop down to the last section which has more WiFi troubleshooting tips.
WiFi Not Connecting from Sleep or Hibernation
If your Windows 8 machine is disconnecting from the wireless network
whenever you return from sleep or hibernation or any other standby
state, then your problem is probably with a power-saving option set on
the network card. To fix this, you need to open the search charm and
type in
Power Options.
Here, click on the selected plan and then click on
Change plan settings.

Then click on the
Change advanced power settings link.

Now scroll down to
Wireless Adapter Settings and make sure the
Power Saving Mode is set to
Maximum Performance.
Other Troubleshooting Tips
Check Network Card at Compatibility Center
You can check to see if your wireless network card is compatible with Windows 8 by visiting the
Capability Center. Go ahead and type in the name of your wireless card and you should get a little report like this:

It’ll have a little blue logo if it is compatible or not. You can
also check Windows RT in addition to just Windows 8. So this is a nice
site to check out if you are having issues with your WiFi network,
especially if it’s not showing up at all in Windows 8 or it’s got a
yellow exclamation sign in Device Manager.
Check Network Adapter Settings
Open Network and Sharing Center, click on
Change adapter settings and then right-click on then wireless network adapter and choose
Properties.

Now scroll down in the list box until you see
Internet Protocol Version 4 (TCP/IPv4) and then click on the
Properties button.

Finally, make sure the
Obtain an IP address automatically and
Obtain DNS server address automatically radio buttons are selected.
Check Wireless Switch
On most laptops, there is a wireless switch or button that can be
toggled from on to off. Make sure you have that button set to On or
press FN + F8 to enable the wireless card. The switch can be anywhere
(sides, front, back, etc), but there is usually an indicator light so
you can tell when it’s on.
Uninstall in Device Manager
Another quick tip is to go to Device Manager, right-click on your
wireless network card and choose Uninstall. Then reboot your computer
and it was automatically be detected and reinstalled. If it’s still not
working after trying this, then read the next tip, which is updating the
driver.
Update BIOS & Drivers
As always, it’s a good idea to download and install the latest
drivers for your network card. This is especially important if you’re
running Windows 8. As for the BIOS, I’ve always been the one to
suggest not updating the BIOS
unless it’s really needed. However, if you upgraded a computer from
Windows XP or Windows 7 to Windows 8 and you tried everything above and
updated the driver, then updating the BIOS might be worth it. 99% of the
time updating the BIOS is just fine, but there are occasions when it
fails and then leaves you with a computer you can’t boot. Only try this
as a last resort and make a backup of your computer first just in case.
Reset the Router
If you’re getting the Limited Connectivity message, then you can try
resetting the router. You can either restart it by just unplugging it,
waiting about a minute and then plugging it back in. If that doesn’t
work and you’ve tried all the stuff above, go ahead and reset your
router. This will reset it to the default settings and will wipe out any
security or configuration you had done earlier, so be careful and be
ready to do that all again. It’s a last resort measure, but it could fix
your problem.
Read my previous post on
how to reset your router.
Remove Anti-Virus or Internet Security Suites
If you have something like AVG Internet Security or Avast or similar
software installed on your PC or tablet, then go ahead and uninstall
that program and see if your Internet connection starts to work. Many
times Internet Security software has been the culprit and you could be
pulling your hair out trying to figure out what’s causing the issue, so
it’s worth trying.
So that’s a lot of stuff to try and practically every sane thing you
can try. If none of this worked, then you could possibly have a hardware
problem with your wireless card. If you have questions, feel free to
post a comment. Enjoy!
