Hello, Thank you for answering.
1. I enabled Ad Hoc Qos Mode WMM (It was Disabled by default). Rebooted. Did not worked.
I don't have any issue with other laptops or tablets in order to connect to my wireless. So , I belive that my wireless device transmiter has no issue.
I belive the issue comes from both laptops from this wireless adapter AC 7260.
2. U-APSD support is Enabled by default
Wireless device transmiter settings:
Laptop setings and feedback when connecting to my WPA2-PSK - User SSID VIrus (It's the name ive chosen)
I tried to manually add the wireless connection but same message " Windows was unable to connect to SSID Virus" (WPA2-PSK)
I wonder if it has something to do with the 64 bit operating system I have.
Or maybe I should change it from Ultimate to Professional or upgrade to Windows 8?
Anyway, this will cost me extra money and extra time!
Your using same Intel® Dual Band Wireless-AC 7260 802.11ac, Dual Band, 2x2 Wi-Fi + Bluetooth 4.0 with Windows 7 Ultimate 64 bit?
I setup brodcast to channel 1, after testing 6. No change. Still doesn't work.
Anyways, it shouldn't be that complicated because I will give one of these two laptops away and the next user might find this annoying.
It's so weird that I can only connect to WEP and not to WPA-PSK or WPA2-PSK.
And I can't say that is a manufacture comopnent issue because that would mean that both laptops has the Wireless-AC 7260 broken or with dislike of compatibility with Windows 7 Ultimate 64 bit.
I have no idea what to do next. Could someone from Intel R&D could take a look at this case, please?
Or, what should I do in order to get help from their side?
Farther down the page of threads on this forum is one titled, "7260AC Disconnecting every 5 minutes".
Go to post #4 in that thread and download the driver linked there. It's a self-executing zip file that will open three folders for the versions of Windows. First, go to Control Panel and uninstall ProSet. Restart the PC. Click open the driver file and save somewhere on the PC. Open the adapter properties in Device Mgr. and click to update driver. Point to the Win 7 folder of the expanded driver file and let it update. Give that a go.
With the exception of Preferred Band, your driver settings are the same as mine. I don't believe that that one would make a difference.
If the 17.12 driver doesn't help, then the problem almost surely lies with the router. Do you have any kind of filtering set?
Good afternoon GattoNero,
I've updated the driver with the one you said. I noticed that only one "Microsoft Virtual WiFi Miniport Adapter #3" appeared in my Network Connections.
After installing the driver, unfortunately, the error appears like always:
After installation, I also noticed that Bluetooth audio has an dislike of drivers that was mentioned by exclamation sign:
I'm afraid, I need to reinstall the previous drivers in order to have everything without exclamation sign.
I tried reset the wireless to factory settings and tried to logg in but still same issue. WEP ok, WPA2/WPA-PSK nok.
It's weird that I just made HotSpot with my smartphone and the security was WPA2 (AES) and the laptop connected with no issue.
The WLAN filtering is disabled by default. Never used it. (checked also)
If it's possible and if you want, I would accept a teamviewer connection in order for you to have a look. You can access the router and also the issued laptop.
When you reinstalled Windows, you should have installed a Bluetooth driver. It's a separate file from wireless. You could try that. https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3622
Even so, it shouldn't affect wireless connectivity. So it seems, no matter what driver you're using, your router isn't going to let you have WPA2. I really don't think that this problem is with the adapter. But I don't know what the problem is. Maybe the Intel guys have some guidance. I'm stumped.
