My wireless ac adapter keeps disconnecting from the internet for no real reason I can find.

I have a Intel dual band wireless-ac 8265 in my desktop which is now as of writing this a year old. It started dropping the internet a couple of weeks ago and I would run the troubleshooter said "default gateway not available" I thought i fixed the problem with uninstalling it restarting my computer and reinstalling it which then made a bunch of updates happen. Now though it still disconnecting but say that "problem with wireless adapter or access point". I have no idea what what is going on and it is stressing me out. What in the heck can I do to fix this and stay online?

Also I can't do a Ethernet connection because of how my apartment is laid out so that isn't an option.

1. Try how it work on the second band. This adapter may work on 2.4GHz and 5GHz band.
2. Check if Bluetooth is working good. Bluetooth uses 2.4GHz band (together with WiFi).
3. Check if both antennas cables are firmly connected.
4. Install the latest Bluetooth driver https://downloadcenter.intel.com/download/29004/Intel-Wireless-Bluetooth-for-Windows-10?product=94150
5. Next, install the latest Wireless Driver https://downloadcenter.intel.com/download/29003/Windows-10-Wi-Fi-Drivers-for-Intel-Wireless-Adapters?product=94150
