I'd ask yourself, what do you use the wireless for
Do you play games ?
multiple devices connected at the same time / stream video on multiple devices?
this will determine your best bet on what you need.
a great start would suggested with at least a wireless AC-1750.
The TP-Link Archer 1750 are OK, i havent seen any gripe with those. Wireless N 450 / AC 1350.
don't set it to " AUTO " you'll have way too much fluxation.
Also to keep in mind, manually adjust your channels on each band you plan on using. It varies in each area. As an example, if you have wireless lanline phones, they normally use channel 5 / 7 and will disrupt your wireless frequency.
I have an ASUS RT-3100, i got off ebay used for 120$, it's never had an issue, runs super smooth.
