I have very basic understanding of networking and I successfully installed the latest snapshot (of today) to Xiaomi AX3600. I was having trouble updating and installing luci (DNS were failing) but then I used SSH and configured it with:
uci set network.lan.ipaddr="192.168.200.1"
uci set network.lan.gateway="192.168.200.1"
uci set network.lan.dns="18.104.22.168"
So my question is: can someone guide of which settings do I need to change, which packages are really useful to install? How to optimize the AX3600 performance in particular?
I have always used NextDNS to block ads and malware, I am wondering if I can set up something similar in OpenWRT. Also having a firewall up and running could be nice. I do NOT have any IoT devices, I am just seeking:
performance using WiFi6 if possible
stability (I hope these snapshots are stable enough, will see).
I changed the IP from 192.168.1.1 to 192.168.200.1 because the network where I live is set up in a certain way that one ISP provider gives access using one switch to many routers, It's a single contract with ISP to give internet access to many, instead that each and everyone of us have to sign a contract with a ISP and have it's own network. Anyway this is just to clarify, it's because of my unusual network here in my neighborhood, doesn't matter.
well, first of all, I have read the quick setup guide but I haven´t managed to use the WiFi. It seems like my devices can't obtain an IP address (SSID and password are correct) but DHCP is turned on in LAN interface. Shall I copy the same settings about DHCP to wan interface as well?
The reason behind that 192.168.200.1 is because internet at my apartment arrives from a switch. There is the main ISP Vodafone router which has been installed by ISP and it is located in a separate building. Then from that router there is a switch which redistributes internet to a few apartments like me with a Rj-45 cable. I just need to connect my router to that cable and set an IP. In fact in each apartment there is a router with a sub-net. So as the main Vodafone router has the 192.168.1.1, the other sub-nets have 192.168.100.1, then 192.168.200.1 and so on. I just changed mine to 192.168.93.1 (because I found out 200 was already in use in another apartment).
I was successfully using internet in my aparment with a previous basic router (no openwrt). All I needed to do was to set this IP address to create a sub-net and everything was working.
Having read this and your configs, you should be able to do the following:
Remove the LAN Gateway IP 192.168.93.1 - it incorrectly self-references the router, which is either invalid or would create some loop (never tested such a thing)
Remove DNS entry of 22.214.171.124 from LAN
It seems you successfully obtain an IP via DHCP of 192.168.1.50/24 and a gateway/DNS setting of 192.168.1.1 from your RJ-45 cable plugged in WAN. Feel free to use 126.96.36.199 on your WAN for DNS config if you desire.
As @frollic noted, the reason you had to change the 3rd octet in the LAN IP to 93 was because if they are both numbered the OpenWrt-default of 192.168.1.x/24 - the router thinks they're the same network, and therefore won't "need to" route.
Right now I am able to surf the web both via cable and via WiFi. However the custom DNS I wrote down does not seem to apply, I still get the DNS advertised by the main router 192.168.1.1. How to force that?
Unfortunately that main router still forces on me its Vodafone DNS. Moreover with the setting you said my andoid phone can no longer use its custom DNS because trying to connect to AX3600 WiFi it says: Private DNS not available, thus it does not connect. As soon as I disable private DNS on my Android, it connects to WiFi.
I need to keep custom DNS in Android settings for scenarios when I am away from home.
To be clear, I wanted to make sure the DNS setting was shown in a screenshot. Your comments about the Android setting and the instructions given for another inquiry confused me. I used 188.8.131.52 in my example so you can follow it exactly.
By browsing to Network > Interfaces > WAN > Advanced Settings:
You are correct @frollic I do not know why but the first time I edited DNS, my Android phone could not use its DNS settings. After putting again to default and trying one more time, now my Andoid can still use its custom DNS server.
Can you elaborate regarding that DoT is very easy to block for me or and ISP?
@lleachii I changed the DNS where you showed, yes:
But still I see that the main router forces me its own Vodafone DNS.
For context: I was already aware that that particular model of Vodafone router given by ISP has a setting to force users to use its own DNS. I can tell you that before using this AX3600 I was using another of these Vodafore router as generic router in my apartment and I set up there custom DNS adress. Guess what, there were totally ignored. The only way I can use my custom DNS is to set them per each device (on Fedora, on Android, on Windows, etc.) because I was not able to use my DNS set up in my router. Now I have a OpenWRT router, and even if I am behind a switch and the main router I am still wondering if I can avoid setting up custom DNS on each device. Better, yet, if I can use DoT or DoH protocols and not plain IPv4 like in the screenshot above.
Remember that the topology of my whole network is: Vodafone ISP fiber cable -> Vodafone router (that nasty one that forces its own DNS) -> switch -> other 3 routers of each apartment, one of those is mine.
