2.4Ghz stupidly slow

[popesloth]

So almost all of my devices use 2.4Ghz only 2 devices don't 1 is on Ethernet and one is on 5Ghz. 2.4Ghz is just unusable. What should I do? I've tried everything resetting my router changing my channels from 6 to 11. I'm using the Comcast router/modem combo box.

Most home routers are only made for 5-6 devices tops and start to run into problems then. There are other business-oriented routers that can support 100+ clients and you won't run into these issues.
