No wired internet connection after uninstalling mcafee

Hi all,

I bought my Acer notebook last month - bundled with Windows 8.1 and a 30 day McAfee trial. All's been working perfectly until I uninstalled McAfee (followed by running their removal tool, rebooting etc. - everything's been done by the book) last night.
Now there ain't no internet on the notebook. My PC and work laptop both connect through the router without a hitch. Troubleshooting doesn't offer any solutions.
I've not yet been able to try a WiFi connection so don't know if that's working or not.
I'm not super-confident with this stuff, but I have checked out various Googly suggestions (network adapters etc.) and nothing's shouting "I'm the problem! Over here!"
I'm hearing all sorts of bad stuff about McAfee - and good things about Defender, which started up on the reboot after the McAfee 'purge'.
I'd really really appreciate some help or guidance here. Feeling a bit lost.
Thanks

Welcome to the forum!

Do the Pci NIC (LAN) adapter and wireless adapter both show up in Device Manager and no errors (yellow triangle)?

Thanks Popeye - good to be here.

In Device Manager>network adapters all eleven of 'em say "the device is working properly".

Although I'm not seeing anything that exactly matches what you're asking, I do see a Qualcomm Atheros AR956x Wireless Network Adapter and a Realtek PCIe GBE Family Controller.

No yellow triangles, no sir.

If it would help copying and pasting anything in here, please let me know. Thanks again.

Eleven network adapters? Saaaaaay whaaaaat! Would love a pic showing that. Eleven adapters is definitely not normal.

Thought I had a lot with two VM adapters:

Well, that does seem quite a lot. Then I clicked to show the hidden ones - which are greyed out in the image. Make any sense at all?

I would start by making a restore point, uninstall everything under network adapters and reboot. Let what is really present re-install.
Also wondering if uninstalling McAfee did something to your firewall settings to mess things up.

Thanks again Popeye. Sounds like a plan - when I click to uninstall, it asks if I want to delete the drivers too? Should I do that for all, reboot and see what comes back?
Cheers, M

No, don't delete the drivers. Simply trying to see if things reset with a re-install.

OK, that was a real step forward - I'm typing this on me notebook via wired connection.
I uninstalled everything and two came back:
1. Qualcomm Atheros AR956x Wireless Network Adapter
2. Realtek PCIe GBE Family Controller
Only thing is, the WiFi isn't working. I checked the Qualcomm and the driver's up to date according to the troubleshooter. It's great to have some internet back, but I'd really like me WiFi back too. Any ideas?
And thanks once more, Popeye.

Have to ask the obvious, is the wifi software/hardware switch turned on? Sorry, had to. :)

Ha! That's a perfectly valid question, Popeye. What I'm seeing now is like this:
  • in PC settings>Network>Connections>WiFi Not Connected: just says "properties"
  • same path to Ethernet Not Connected: gives device details (Realtek PCIe etc)
  • when I plug in an ethernet cable, I get instant network access.
  • The green area that pops up when I click on the network symbol on the bottom bar shows neither the WiFi on-off switch nor the flight mode switch - both of which were there before I uninstalled McAfee
  • windows sez the WiFi device and driver are both working fine and uptodate

Making progress here - McAfee gone/ Windows Defender up and running/ ethernet connection fine - thanks to you, buddy. Now if we can just fix that pesky Wiffy....

Hi, just checked: Qualcomm Atheros AR956x Wireless Network Adapter version 10.0.0.285.

I just downloaded the files just now - and installed via the Device Manager like you said, Popeye. Also rebooted. The Driver tab is now updated to version 10.0.0.298 and sez it's working properly.

Still, when I go to Networks>view connection settings>WiFi shows no properties while the Ethernet connection gives all the details. And works, of course.

Scratching my head quite seriously now...

Go to Control Panel, Network and Sharing Center, Setup a new connection or network, manually connect to a wireless network.

Aargh, when I get to Set up a new connection or network, there is no manually connect to a wireless network option. Only these:
Connect to the Internet
Set up a new network
Connect to a workplace - none of which do anything constructive for me.
As you'll already have guessed, I'm not very clever with computers, but this is dumbfounding me.
I've got the right network adapter, with the latest driver, it's enabled, but in Network>Connections >WiFi it just says Properties, whereas Network>Connections >Etherenet gives device and driver details (and works).
Also in Network>Flight mode, there's Flight mode - with one slider switch, and Wireless devices - with one slider switch for Bluetooth. WiFi should show up here, but all I'm getting is Bluetooth. I just don't get this.

Something ain't right for sure. Kind of getting down to applying a restore point, a repair install or a refresh. I am assuming you ran the troubleshooter.

One more thing to try:

Click Start > All Programs > Accessories, right-click on Command Prompt and choose Run as administrator. Windows 8 users press [Windows Key] + [X] and select Command Prompt (Admin).
At the command prompt type: netsh winsock reset catalog and press [Enter].
Next type: netsh int ip reset reset.log and press [Enter].
Restart your PC for the changes to take effect.

Yup, something ain't right here. And yup, I did run the troubleshooter, more than once.

Of course, right up to the point when I uninstalled McAfee and ran their removal tool, everything worked perfectly on the notebook. I'd happily go back to scratch on this - ideally to the condition the notebook was in when I bought it but without McAfee and with Windows Defender. I don't actually recall doing anything to start up McAfee in the first place, as it happens. Any view on that?

Sometimes a trial version is included on new laptops. Did you try the reset I posted above?
