Need to Reboot RAX35 for intermittant wifi dropping after 2 weeks

Ever since we have been under Stay at Home, it seems like every 2-3 weeks I have to reboot my router as I will start to experience the wifi dropping on my 3 laptops in use at home.  The wired computers/devices work fine, but not the 3 laptops.  They will drop wifi every 30 minutes or so, even though 1 of them is 10 feet from the router.  I have Verizon gigabit service so plenty of ISP bandwith.  I did notice I am using about 14 GB of data a day through the router.  Once I reboot it, is seems to be better for awhile.  I hooked this router up in early January 2020 and never had to reboot until the end of March.  Since then, 3 reboots.  Anyone else having a similar issue?  Seems like a memory not clearing bug in the router...
