Ran my whole shop on a $60 home router for 2 years before a tech in Boise set me straight
He asked how many devices we had on it and I said 14, and he just started laughing. What's your setup look like for a small team, do you rent from the provider or buy your own?
That "tech in Boise" laughing at 14 devices is exactly how I found out my old Linksys from 2016 was the reason our card reader kept dropping during lunch rush. I had a similar thing happen with a printer that kept going offline every single day around 2pm. Turned out the thing was fighting the microwave for the same wifi channel, no joke. Moved everything to 5ghz and it never blinked again. Sometimes the fix is just knowing which band to stop using.
