I have two routers at home. One is standard router that is linked to my modem, the other is a WiFi router that also has additional ports. The WiFi router is connected to the first one. I have this setup for security reasons, as I was told that this would be more secure.
But sometimes when this WiFi router is connected, I lose the Internet connection (whether the connection to the modem fails or maybe somthing else goes wrong, at least the Internet connection doesn't work). After I power them both off for a minute or two and then power on again, then everything works.
Can this WiFi router be the reason for these failures?
PS: It is secured with WPA and I am not aware of anyone hacking my router(s) or network.
Update:
I have non-WiFi D-Link DI-604
router and WiFi Asus WL-530gV2
. D-Link is connected to modem and Asus is connected to D-Link. I'm using the default firmware that came on the routers from the factory.
Today, when I powered on my PC, the connection was down again. At the moment I have disconnected the Asus (WiFi) router. So far so good.
Update 2:
PC is connected to router 1, not over WiFi since it is non-WiFi router. PC has IP 192.168.0.xxx and he receives it from router 1 and Android device after connection to WiFi router gets IP 192.168.1.xxx
Update 3:
Such scheme is better due to that all PCs at home connect to non-WiFi router and WiFi router is connected to non-WiFi router, so it mostly doesn't interact with home PCs.
I don't know anyone who would like to hack in at my house to use this connection.
Just because you don't know who would doesn't mean there aren't any. Still, WPA is better than WEP...or nothing at all.
