I have an ASUS RT-AC68U with the Tomato USB firmware and I want to extend the existing wifi coverage (a LTE modem with router) for better reception in the rest of the house. Having the same subnet or essid is of lesser importance - no devices need to talk to one another. So I got this working somewhat, but with problems. The existing network has ESSID "Net A" and subnet 192.168.0.0 (192.168.0.1 is the LTE modem). This is what I did:
- disabled DHCP on the default br0 bridge setup
- set the gateway to 192.168.0.1 on the br0 bridge setup
- on the 2.4 Ghz network I set the "Mode" to "Wireless Ethernet Bridge" and entered the network details of the host network ("Net A").
- on the 5 Ghz network I set the "Mode" to "Access Point" and the ESSID to "Net B"
- I set the IP address of the device to be 192.168.0.2 (I think)
What works:
- connecting to the 5Ghz "Net B" works great and it connects wirelessly to the host LTE router
What does not work:
- connecting to "Net A" while ASUS is powered on
- connecting to the Asus admin interface using the assigned IP of 192.168.0.2 (tried both "Net A" and "Net B")
If I power off the ASUS I can again connect to "Net A" without issues, meaning it seems to interfere somehow with the setup of the LTE modem. I thought that it might have been somehow due to me connecting to the Asus router using "Net A" (somehow - I do not know if it makes sense), but arp -a
(which I believe should show which external MAC resolves to which IP) never changes for 192.168.0.1. Should not this change if I connected to the Asus?
