Hello Ares,

Please apply the settings from the following document, as they normally help in this type of situation:

http://www.intel.com/support/wireless/sb/CS-030709.htm?wapkw=wifi+recommended+settings Wireless Networking — What are the Recommended Settings for 802.11n Connectivity?

If the issue persists, go to Windows* Device Manager - Network Adapters, look for the Intel® Wireless Adapter and go to the adapter properties, in the Power Management tab, toggle off/on the option "Allow the computer to turn off this device to save power". Check if the behavior improves when you change this setting.

Please remember that for immediate assistance, you can http://www.intel.com/p/en_US/support/contactsupport Contact Intel Support, so one of our support engineers can assist you directly using the contact method of your preference.

Since the issue persists after applying the recommended settings and power management configuration, please try the following:

- Go to the Windows* Power Options - Change plan settings - Advanced power settings, and set the Wireless adapter to Maximum Performance, when plugged in and on battery.

- In the Adapter properties, http://www.intel.com/support/wireless/wlan/sb/cs-025393.htm Advanced Wi-Fi Adapter Settings, set uASPD Support: Disabled

- Update the firmware in your Wireless access point.

If the issue persists, please provide the following information:

- For each client with the issue

Computer brand and model, operating system (including 32 or 64 bit), wireless adapter model, wireless driver version

- Router/Access Point model and firmware version.

- Have you checked if the issue occurs with other wireless networks, or other access points?

- Does this happen only with Wireless N? or does it also happen when using 802.11ac?

Hi Jonathan,

yes we have use max performance and disable uapsd.

We try different wireless AP bought from market and both can replicate this issue, so it shall not related to the our AP firmware.

You can try it by Netgear R7500, Netgear R8000.

It happen at 802.11ac

Ares

Hello Ares,

There have been multiple driver updates for the Intel® Dual Band Wireless-AC 7260 and Intel® Dual Band Wireless-AC 3160 since our last interactions, connectivity with older devices has been one of the main improvements.

Please contact your http://www.intel.com/support/oems.htm Computer Manufacturer Support and obtain the most recent driver version available for your Wireless adapter.

As second option, you can use the http://www.intel.com/p/en_US/support/detect Intel® Driver Update Utility, this will detect which driver updates are relevant to your computer, and then helps you install them.
