Greetings. I am trying to configure a Linksys WRT 3200ACM as a repeater, following the directions at https://openwrt.org/docs/guide-user/network/wifi/relay_configuration. Every time I get to the step of changing the LAN settings on the repeater, I permanently lose contact with the router and have to do a factory reset to get it back.
A little more background: I'm trying to do this using the LUCI GUI. My PC is running Ubuntu 16.0.4.
Experience suggests that the problem is my ignorance, but I don't know what I don't know! Here are some things I'm not sure about that may be causing the problem:
- The instructions say that the LAN interface must be on a different subnet to work. Ignorance, round 1: I can't find any setting labeled "subnet" in the interface. The interwebs tell me that subnet and netmask are usually interchangeable, so I've been setting the ipV4 netmask to 192.168.2.0/24, as suggested in the diagram in the instructions. Could this be the source of my problem?
1a) I notice that in the screenshot that accompanies the first step of the instructions, the netmask is 255.255.255.0. Is that evidence that I'm doing the wrong thing here?
I have tried to reconnect to the router using an Ethernet connection and wifi (having enabled a wifi connection before changing the LAN address), and using the addresses 192.168.1.1 (default) and 192.168.2.1 (the one I just changed it to). Nothing works--I get browser (Firefox) error messages telling me that the connection failed.
I have tried changing the network settings in Ubuntu, but it's possible that I don't know how to do that correctly. Again, I'm doing this using the GUI. I tried by clicking on Edit Connections-->(editing the Ethernet and/or the Wireless connection)-->IPv4 Settings-->Changing Method to "Manual"-->adding an address (192.168.2.10/255.255.255.0/192.168.2.0; which I understand to be a static IP address for my PC, the subnet/netmask (it won't let me enter 192.168.2.0/24, but I notice that after I save this address, exit Edit Connections, and then come back it has replaced the 255... with 24), and the IP address for my router's LAN)-->Routes-->adding the same address as a route. Nothing seems to make any difference.
I also tried following the CLI method of setting up the repeater, but I can't actually find instructions there (that I can understand, anyway). Once you turn on the wireless on the router, everything else seems to be merely the CLI output that reflects the new configuration, not step-by-step instructions about how to create that configuration. Again, probably my ignorance.
I would welcome any help. OpenWrt is working great on my primary router (same model). I'm currently using a Netgear repeater that is not OpenWrt compatible, and I'd like to switch to improve security and control.
