What can be the reason for the long loading of pages?

Question

Computer networks

Very dumb question, I know. There is a network of 20-30 computers, about 10 devices via WiFi, a couple of switches and go to the network through a custom Beeline smart box one router. More files and speed tests pass without problems, but ordinary web pages take a very long time to load and often a time out error occurs. There is an assumption that the router can not cope, but these are my guesses, so I'm waiting for an answer to this question.

Answer 1

Well, you understand that devices of this class are not designed to serve dozens of users, right?
Diagnose: compare whether the symptoms recur with a decrease in the number of clients, look at the logs and LA (if possible) on the router, etc. Arrange load testing.
Better replace SOHO with something more suitable.
