I just installed OpenWRT last night on my WAX202B.
I'm running an ethernet from my router's LAN port to my extender's WAN port and it is detected in Interfaces, but when I try to set up a 5ghz band, it does nothing. I tried setting the Network in General Setup to wan but that didn't help. The 5ghz radio also turns on and off sometimes?
What's even weirder is that my 2.4ghz band shows up in my wifi settings but not my 5ghz. And whenever I click on the 2.4, it is stuck in loading and eventually disconnects.
And I think it's configured in router mode?
I don't know if I should be using it in router or extender mode. I have some smart devices that I want isolated from everything else, but my main router doesn't have a 2.4ghz band, so would using it in router mode be better?
I haven't tried plugging into the WAX202's WAN and bridging the WiFi to it (in fact WAN isn't setup in a bridge and that's kinda complex to setup on routers with DSA switches like the WAX202 - unless you really need the extra port). I surmise your issue is that WAN doesn't exist in a bridge in which the WiFi can connect.
I would simply connect to LAN, make LAN DHCP client (or set it to an IP on the router's Network), remove DHCP on OpenWrt's LAN too...again there's Wikis and threads on that already.
I assume this would be with the same Ethernet you used to connect the WAN port. Just use LAN1, LAN2 or LAN3 instead. Feel free to follow the Wiki - your question is literally answered in the "TL;DR" section.
( You mentioned Netgear again.) OK, feel free to configure it as such in OpenWrt - I just noted it was possible; but you noted you were a n00b, so I didn't want to make things complex. If you insist on using the WAN port also, see:
In any case, you need to configure your interfaces properly. It seems simple just to alter LAN.
Oh I'm sorry I wasn't understanding what you meant. I changed to one of my lan ports and now ethernet seems to be working, but whenever I go to 192.168.1.1, it brings me to my main router's page, how do I access the 202?
Again I'm really sorry. I'm trying my best. I don't have much clue what I'm doing.
I think I set the LAN IP in the OpenWrt to 192.168.1.2, which is not used by any other device at the moment.
I turned off DHCP.
I put in Cloudflare's DNS (184.108.40.206)
My issue now is that I can't connect to the OpenWrt. In my network settings, it shows my ip address and subnet mask but no router ip. I tried the LAN IP I put above to access the browser, but it says no internet. The SSH also can't be accessed with that IP.
