I have a DELL XPS 15 Touch 9530 with the Intel Dual Band Wireless AC-7260, and the Wifi has no end of problems. With the default 16.0 driver it keeps disconnecting from the network, showing limited connection etc. Since then we have tried replacing the Wifi card, but it did not help. Upgrading to the latest 17.0.2.5 driver stops the Wifi from disconnecting, but the connection is so bad none of the web pages will load up.
We are using two access points (D-Link DAP-1665 and TP-Link WA9091ND). It works better with the 5Ghz Wifi from the D-Link access point, ping results as below:
