The worst router I’ve ever seen was a D-Link. I was in a position where I had to provide support for it, and in the end I gave up and bought them an ASUS with my own money. It ended up being worth it, just in terms of time and aggravation saved. The software and firmware on the D-Link were garbage, and so was the actual build.
Ubiquiti ftw After a brief romance with VyOS and RPi based APs, Ubiquiti came along and swept me off my feet Currently using their gear throughout a 300-ish person office. Easy to setup, no issues that weren’t our fault in the first place. Great kit for startup and growing type situations
Some of them obey the Law of Plastic Box: a device in a plastic box does one thing but not more than that. A Huawei router is OK if I just do routing, no WLAN, and put a TP-Link box as a WLAN beside it. Etc.
The only exceptions I have had in consumer-priced equipment is Ubiquity, which is great, and a small Finnish company called Telewell (which make cheap plastic things in China but strangely has never failed for me). The UI with Telewell is still the typical consumer-grade Web UI.
