Question

WiFi

Good evening, please advise a good wi-fi router for an office of 120m2. 7 classrooms with 2 computers. Not including smartphones. Neighboring buildings do not interfere with the signal, the office is in the private sector. Drywall partitions. The Internet is connected via a telephone line.
I understand a little about routers, I configure it myself and connect it myself. I don’t want to save, but I don’t want to overpay either, I need the help of experts, since I’m not a pro in this matter. Thanks in advance.

120 sq.m. not that big of an area. I would try and get by with the usual zuhel.
