Gigablast: Mac Loses WiFi while MS Surface Book Does Not

I know this sounds crazy, but my Mac will suddenly lose the WiFi signal but a MS Surface Book 2 connected to the same signal keeps on humming. I thought it was this Mac in particular but I recently got rid of boot camp on a different Mac upstairs and made it a dedicated Mac and now that too suffers sudden drops from the WiFi. Both are running High Sierra. I thought at first it was the the wireless adapter so I bought a USB one and stuck that in my Mac downstairs but the same thing happens. The only fix is either to restart or to switch to the other network I have running through an Eero. There must be some conflict and am hoping someone here can tell me how to fix as besides being a PITA it also causes work issues especially on video calls, as you can imagine. Thanks!
