High network instability

[ladal1]

I am currently trying to fix internet at my fathers house and right now I am out of ideas. 

 

Problem is that after even a shorter use (20 minutes) internet just stops working for about 2-3 minutes (more or less).

 

The network is the connection to ISP through Wi-Fi, then into a switch that splits it into plugs around the house, one of which runs into ASUS RT-AC1200G+. Its a new router he recently bought, because his last simply stopped working (to me seemed from simple examination as a blown off capacitor or burned out other way, didn't bother doing more because it was really old router). I tried basic troubleshooting but I have problems coming up with what could cause it other then the router by itself (Tested the configuration and they should be correct) or the receiver from the ISP.

Are you cascading or using the router as an access point? Some ISP do NOT allow you to connect cascading routers without giving you many troubles.

 

One thing that you should check is if you have DHCP activated on both the router and the modem. If that's the case, leave it to the router for cascading or to the modem only if AP. It causes many problems with IPs and DNS and it might give you frequent "connection limited" errors on windows.

Currently it is in simple AP mode, and it runs its own DHCP server, other then that everything should be delegated to the receiver.

So lf I understand right there is a a modem which works as DHCP client and the new router/access point also?

are they working in the same subnet (ip range)?

I think you might just have found the problem, for some reason I completely forgot that the receiver is running its own DHCP probably (It was set up by someone else and with the previous router it was a bit of a whack job) I will look into it later today, when I get there, but I think that might be at least part of the problem

I thought that it may be it, but now that I have tested it, it seems it is not the problem, the router runs in AP mode, therefor not running DHCP by itself. 

 

I also tried further tests (running dhcp with its own subnet, and similar and still can’t find anything
