Unable to connect to WPA2-PSK on Windows 7 Ultimate 64 bit

Nov 28, 2014 7:17PM PST

Good afternoon everyone,

Could you please be so kind and help me solve this issue I'm experiencing right now?

At this moment, I'm unable to connect to WPA2-PSK wireless.
When trying to connect, I receive "Windows was unable to connect to ..." error.
No issue on WEP connections.

System: Laptop Lenovo IdeaPad Y5070 cu procesor Intel® Core™ i7-4710HQ 2.50GHz, Haswell™, 15,6" Full HD, 8GB, 1TB, nVidia GeForce GTX 860M 4GB.

The Ethernet cards installed on machine are:

Realtek RTL8168-8111 Family PCI-E Gigabit
Intel Dual Band Wireless-AC 7260
(also Bluetooth Intel Wireless 4.0 + HS Adapter)

Operating system used: Windows 7 Ultimate x64
Same issue on another identical laptop.

Sorry no.

I've run into this on a few machines and I can't fix it since the driver code is closed source. One workaround appears to setup the connection manually. But there's some deeper issue that seems to be at play here.

I didn't find Windows 7 shipping on that model. This could mean you loaded some other OS and are finding issues with what ever drivers you found.

So this is again why I doubt it can be fixed. Let's hope someone can fix this one.

I'd restore it to the factory OS and tell the forum what you need from Windows. For most, installing Classic Shell on Windows 8 will be enough.

Thank you anyway!

This model came with no Windows operating system. I had to install one.
On the Lenovo website, there are drivers for Windows 7 and Windows 8. So, I thought that any component should have no issue with these two operating systems.

OK, so there are drivers.

suggestions

but not guaranteed to work.

1) be sure to use same passphrases on both the router and the computers' connections.

2) try setting up not has homegroup but using the business mode to setup the connections. If that works, you can set it to Homegroup and still have it work then. I ran into this for my wife's w7 computer which didn't want to connect to the home LAN when all other computers had no problem.

3) Use WEP and have each computer's shared folders protected with passwords.

PS - Why not try a Linux distro on it?

Thank you for your implication!

1) Same passwords are inserted - Checked many times with other devices - Other Laptop, tablet and smartphone.
Password is correct.

2) This laptop will be sent to someone and he will usualy travel. Most of the wireless settings in my country are on wpa/wpa2-psk security. This means that the laptop should work without doing special settings for each connection. It should work in any condition like any other laptop.

3) WEP works with no issue. Still, like I said, most of the wireless connection in my country has wpa/wpa2-psk. Intel® Dual Band Wireless-AC 7260 802.11ac, Dual Band, 2x2 Wi-Fi + Bluetooth 4.0 device, from this laptop, should connect on any security check-ups.

By the way, if I have a special line with WEP, should I make some special settings in order to avoid any unwantted access? I setup a password for the connection, same for WPA2-PSK.

WEP

requires a key, so if using it, should already be encrypted, but it's susceptible to easy hack using some common tools available for free. It's about like locking your front door, it discourages someone trying door handles, but not much good against a "bump key".

Item 2 tells a tale.

For a test, disable the internal WiFi connection and use some USB WiFi dongle. I did this for a client to demonstrate the driver fault.

Why can't the owner/user connect on their own? I don't want to judge here but some IT staffers cater too well to the point they pander to users a little too much.
