What model (Thomson) network router? Is it running the latest-and-greatest firmware? And are you setting IP addresses/protocols through the router itself or through Windows?
I suspect the problem might be the (limited) options provided by the ASUS 3T3R WiFi driver - it should allow Windows to fully control and configure it, but (as we all know) Windows can sometimes be problematic over the most basic things, lol. You can try a generic AC1900/BCM94360 firmware and drivers, if any are available (for Win10).
I wasn't impressed by this built-in ASUS WiFi accessory, it had poor signal and too many connectivity issues. I ended up installing an AC1900 adapter card which I found works very perfectly (with consistently strong signal/bandwidth) in Win7, Win10, and linux.
