I've struggled through this problem for months but seems still failed.
Configuration:
Notebook: Lenovo X240-20AM with Windows 7 Enterprise SP1 64-bit
Browser: Chrome (latest version)
Wireless Interface: Intel Wireless-N 7260
Driver Version: Intel Wireless 17.0.2.5 (16/04/2015)
U-APSD: Disabled
4G Router: ZTE MF-91 802.11n only
Encryption: WPA2-AES
Power Management: "Allow computer to disable this device for power saving" has already been disabled.
The wireless connection function properly with enterprise AP or home use broadband router (TP-LINK 1043ND with DD-WRT). The connection last forever and properly.
However, once I try to use the mobile 4G router, the connection could only at most online for around 90 minutes. Then, the bottom right icon still shown the connection is built. However, the browser could not connect to any website and only shows as 'Connecting...'. Same problem occurs while using tethering feature on my 4G mobile phone (LG Optimus G).
While the connection fail and revert to enterprise AP, the browser could access to internet website.
I've tried to disable and enable the wireless interface but still fail. The only way I could do is to reboot the notebook and the connection could be up again.
Grateful if Intel could investigate and resolve it.
Thanks a lot!
Quentin

Quentin, I am sorry to hear that you are having issues with your system.
- I would like to know if you have tried using a previous driver version.
- It will be also helpful to know if it is working by Dynamic Host Configuration Protocol (DHCP) or static IP.
- Are you connecting to the 5 GHz or to the 2.4 GHz?
Regards,

Hi, Sylvia,
Thanks for your reply.
I've tried previous version such as 16.8, 16.10, etc. It's mainly working under dhcp and 2.4ghz channels.

Qwb 4, do you get an IP address when that issue occurs?
When it shows connecting?
Do you lose connectivity to all or just to the internet?

Hi, Sylvia,
The IP address was got before the issue occurred and the address was not reset.
The "connecting" was shown up in browser's status bar (chrome). IE failed to connect as well.
Yes, all the connectivities were lost even for my Notes and network drives access.
Regards.

What is the adapter's IP address when the issue occurs (from ipconfig)? Can you ping the 4G router at such moment?

Yes, the IP address was 192.168.2.2 and I could ping the 4G router successfully.

Are you connecting the LG phone to the computer or to the 4G router?

The X240 failed similarly either by the 4g router or by the LG android phone. These two devices could connect to internet independently. No connection between the phone and the router.
For your further information, while the notebook fails to access internet, another device which use the 4g router could access to internet successfully.

According to your original post you haven't try the latest driver version which is 17.0.3. Could you give it a try? Please let me know the results.

Dear Sylvia,
In fact,, I've already been using the 17.0.3 version. I've started the logger and will come back to you once the problem happens again.
Thanks & regards,
Quentin
