The "802.11n mode" is available for 802.11n Intel® Wireless Adapters. It is not a valid setting for the Intel® Dual Band Wireless-AC 7260. The AC 7260 and other 802.11ac adapters use the "HT mode" value:
HT mode (supports 802.11n compatibility)
VHT mode (supports 802.11ac compatibility.)

Here are some initial recommendations for the connectivity issue:
- Apply the settings recommended in the following advisory:
- Check the router and make sure that you are using a different SSID for the 5 GHz band, and that it is properly configured for 802.11ac.
- Review the QOS configuration of the wireless Access Point and make sure it has "WMM" enabled for the network. Also, any access list, or priority settings must be disabled, or at least giving high priority to the PC using the AC 7260.
Thank you Jonathan for your answer.
Is there any specific reason you are recommending to set up the 5GHz SSID WiFi as different to 2,4 (and not having both with the same name)?
I've followed the recommended settings topic.
WMM is enabled.
Is there any way I can verify if I'm using g/n/ac mode?
You can check the Radio type and other properties of a connected wireless network by clicking on the wireless icon of the notification area, then hovering over the network.
Regarding the SSID's, for optimal performance you would prefer to separate the networks. You will be able to confirm if the computer (or device) connects to the 5 GHz network; take into consideration that 802.11ac only works in the 5 GHz band.
Also, you may want to check your Access point documentation to know how to get the best configuration for it.
