Are you running Windows 10 on your laptops?
https://www.webnots.com/fix-wifi-connection-issue-in-windows-10/https://www.drivereasy.com/knowledge/wifi-keeps-disconnecting-or-dropping-out-on-windows-10-solved/When it drops, don't try to connect. Just open a web browser and see if you can get to the Internet. Also, go to start > type in
CMD. At the prompt type
ipconfig. see if you computer is getting an IP address (192.168.0.xxx unless you changed the router's LAN IP address). The default gateway should be the IP of fthe router (192.168.0.1).
This is a difficult issue to figure out what is happening. It's either environment, some weird incompatibility issues with the adapters and router, Windows issue, or the router is defective. If there is interference or your laptops are in a spot where it cannot communicate with the router it may explain it. Remember wireless is 2-way communication. It doesn't matter how strong the router signal is, if the adapters signal isn't strong enough or there is some interference near the laptops, the connection will not be good. But the fact that the only way to regain connection is rebooting the router, not the laptops, is making this more difficult.
Does everything work good other than the dropping?
If both laptops are connecting at the same time, does 1 drop while the other works or do they drop around the same time? If all other devices that are connected to the 2.4GHz band drop around the same time then it definitely is a router issue.
Where is the router located? How are the antennas situated? What is around the router? What is in between the router and your laptops when they drop? Make sure there is at least 3 feet of air around the antennas.

Wireless is very sensitive. Fish tanks, appliances, bluetooth, wireless ceiling fans, mirrors, glass, etc can cause issues.
