Intel 7260 kills my home Wi-Fi and doesn't work with HDMI plugged

[ACast24]

I have a Dell Vostro 5470 with an Intel Wireless-N 7260, and it regularly kills my home Wi-Fi for everyone connected, and the only way to solve is rebooting the router.

It also doesn't work when I plug an HDMI device. The internet goes unusable and only works when I unplug the HDMI.

How can I solve this? I'm using Windows 10 build 10162 now, but it happens on Linux Mint, Ubuntu, Windows 8 and 8.1 OEM.

My router is an TP-Link WR941ND revision 5.

This Wi-Fi chip also has some connectivity issues, but I managed to solved it using some other workarounds.

Asthosbr99,

We would like to start with a few questions and some information regarding Windows*10 and Linux* driver updates.

1 - When you say it kills your Wi-Fi for everyone to connect, is it because you are sharing your Wi-Fi profile through your laptop?

2 - If you are sharing your Wi-Fi profile through your laptop, how many devices are you trying to connect at once?

3 - Is this card the original wireless card that came installed in your computer when you bought it?

4 - What type of HDMI device are you connect that causes this issue?

5 - Is the router firmware updated?

Regard Windows*10, Intel does not comment or provide support for third-party products that have not been officially released.

If this card is the original one that came installed in your computer, we recommend that you contact your computer manufacturer first to see if they have any updates that could resolve this issue since the drivers found on our https://downloadcenter.intel.com/product/75439/Intel-Dual-Band-Wireless-AC-7260 Intel® Download Center are generic and may not meet the requirements of your system. *Please know that no drivers for Windows*10 is available for now. You are invited to check again for possible updates after this OS is officially launched.

As for Linux*, we recommend that you seek assistance here: https://downloadcenter.intel.com/download/17045/Intel-Drivers-for-Linux- Intel® Drivers for Linux*

"1 - When you say it kills your Wi-Fi for everyone to connect, is it because you are sharing your Wi-Fi profile through your laptop?"

No, I'm using a domestic router. An TP-Link WR941ND revision 5 to be more exact.

"3 - Is this card the original wireless card that came installed in your computer when you bought it?"

Yes.

"4 - What type of HDMI device are you connect that causes this issue?"

TV and monitor

"5 - Is the router firmware updated?"

Yes

"If this card is the original one that came installed in your computer, we recommend that you contact your computer manufacturer first to see if they have any updates that could resolve this issue since the drivers found on our https://downloadcenter.intel.com/product/75439/Intel-Dual-Band-Wireless-AC-7260 Intel® Download Center are generic and may not meet the requirements of your system."

Dell is actually saying that is Intel's fault for making a bad driver... So here I am.

"Regard Windows*10, Intel does not comment or provide support for third-party products that have not been officially released."

If that only happened on Windows 10 is fine, but it also happens on Windows 8.1 (that is released)

athosbr99,

We recommend to use the drivers from the computer manufacturer because they often include customization to the hardware or drivers. This online document contains this piece of information. http://www.intel.com/support/wireless/wlan/sb/CS-031167.htm Intel® Wi-Fi Products — Why Doesn't My Laptop Recognize My New Intel Wireless Adapter?

Have you tried to uninstall it completely from device manager and then reinstall them back from Dell's support page? Also, checking your firewall and antivirus configuration may help you resolve this issue as certain configurations may impact directly on the connectivity.

Check this other online document regarding the recommended settings: http://www.intel.com/support/wireless/sb/CS-030709.htm?wapkw=wifi+recommended+settings Recommended Settings for 802.11n Connectivity

Since you are using a single-band router, you can access its settings and set the bandwidth on it for 20MHz in 2.4GHz only, you should also change this in the Advanced properties of the wireless adapter.

It is also recommended to try changing the channel used by the wireless router.

Disabling Bluetooth* if not in use, also helps to improve your experience with your connectivity, since Bluetooth also operates in the 2.4 GHz band.
