I never dreamed it would be this hard to buy a cheap router these days with removable antennas.
If money isn't an issue I'd get a refurbed r7000 like I linked above.
Those suckers are goooood.
Yeah, when I bought my WRT-1200AC, it was used on eBay, liked it just fine (even with factory firmware), so later I bought another one on eBay used to install on my off-grid property. Then later I decided to buy another one on eBay used, to keep for a spare, and wound up sending it down to my wife's family in Mexico and they use it now.
Once I find decent 'silver bullets' in my life, I tend to like to standardize and keep buying same thing, so I have plenty of hot spares so to speak.
Same like battery cells, I had decided with 280Ah EVE (they were the largest at the time), so every other battery I've built ever since (12v or 48v), I have lots of compatible spares, so I can have replacements or repurpose things as necessary to stay flexible. I keep spare of the same BMSs too. 2 Spare LV6548's, spare cars, trucks, etc.
I have 3 of the same 2014 Macbook Pro's, multiple other of the same Thinkpads, 3 of the old 2014 iPhone SE's, etc.. Still use this old gear today. Life stays easy for me when I have spares to account for failures (which are likely).
Whenever I have a failure, I keep the spare all pre-configured and ready to plug in and go. Then deal with fixing the broken part later. With new parts, it is expensive to do that, but with used parts, it is affordable to buy more than one, to have no-single-point-of-failure when possible.
There are times when I decomm certain things in my life though, where I never wound up needing the spare, but the peace of mind it brought was priceless.
