I'm living in a compound and they offer free internet on their own router.
I'm doing a small LAN between my machines (PC, Laptop, TVs, etc...) and to avoid sharing folders with other residents I've changed the ip address of my E4200 router and just made it an access point (or so I think it is).
The default gateway of the main compound router is 192.168.1.100
this router has a DHCP server on from 101~200, I set my E4200 router internet connection type to static IP and put 192.168.1.150
Then I made the E4200 router address to 192.168.2.1 and made its own DHCP server from 192.168.2.2~30 with subnet mask 255.255.255.224
But i've been having problems like sudden network disrupts every 5 minutes or less which starts to get really annoying later. I can't even watch 20 seconds of a youtube video without getting interrupted! I called the technician but he was out of the city, but he told me there might be an interference between another router and the main router, is my router causing this problem?
Since there are other residents in the building, someone might have another router that is not setup properly. But I can't make sure if it is from me or not, am I doing something wrong?
here is a simple sketch of how it looks like:
