i use to work IT at a place that used those cisco AP’s and i always considered getting one for myself to drown out the other AP’s in my apartment building because my wifi was also spotty no matter what channel i picked and whatever survey i took; the price tag at the time (around $1k+ at the time) was the only thing preventing me for doing so.
watch out for your battery.
i don’t do proxmox; but i do a lot of virtualization through kvm/qemu on my own laptop and the battery can take a beating if you don’t mitigate it somehow. i’ve had this laptop less than 6 months and the battery condition is already at 67%.
i’m lucky in that i got this laptop from a linux company so i can can order replacement batteries; but most people don’t (willingly) have this luxury anymore.
