I just installed the latest openwrt firmware on my older TP Link router and it's working without any problems.
I'm very new to openwrt and I have problems setting up a second wireless network.
Let me explain: I'm using a fritzbox as main modem router. Lately I have some problems with the wireless functionality. So to test it further I decided to confgure a different router as Access Point - where I just installed openWrt on.
What I want: One wireless network for internal use, where all laptops and mobile phones are connected, in the same subnet like my fritzbox.
A second wireless network for the "internet of things" or guest network, with a different subnet of course. The gateway needs to be the fritzbox though, of course. And the IoT network is not allowed in my internal network, but the internal network might want to access hosts in the IoT net.
I followed a few guides on this topic, but I just don't get it to work. First I followed this one:
I can connect to the network and get an IP from the dhcp service, but I can not surf or ping any ip address.
Then I tried this one:
But I don't think that's the right one either, because there is no possibilty to add a second network with appropiate firewall settings and stuff.
I think the problem is that I don't have a real "WAN" or it's not set up correctly. I have no idea what I'm doing wrong. Can someone help me?
Thanks in advance!
