Hello guys.
What I used to do with the cable connected was just setup the Mi 3g as a Dumb Ap and configure samba. His SMB server was shown to every device in my network.
This time I did the same thing, but now since I can't connect the router through cable, I connected my 3G in my 5GHZ wifi in the wireless interfaces > scan > add (lan option).
Now, I can't even acess openwrt web page of the 3G modem through the main router or other devices in my lan, I just have acess to the 3G router, when a plug the cable to it.
Can you guys pls help me out? I'm struggling a lot.
I'm kinda noob and this may be a very easy thing to adjust but I really dont know what else to do.
I'm going to guess that your wifi uplink is not associated with the right network or firewall zone. We need to see how it is configured, though.

BTW, I even tried changing the subnet, still doesn't show. main router is 10.10.10.10 and Mi3g 192.168.1.1.
Mi 3g is getting the ip 10.10.10.217 on the main router.
opaulodapper:
10.10.10.217
This is the address you should use to access the Mi 3g, since that is the IP of your main subnet. So, from a computer on your 10.10.10.0/24 network, can you ping 10.10.10.217? Can you access the LuCI web interface and/or ssh at that address?
So, through the main router, I can ping.

10.10.10.236 is my pc.
I can't acess the router in that link through luci or ssh, i just can acess it again pluging his cable in my pc.
thaat doesn't make a lot of sense, but we'll figure out why. I don't think there is an issue with your OpenWrt configuration, though.
Try disabling the windows firewall and then test the pings again.
Is there a chance of the issue being on the main router? (ax3600 with rc3)
I don't think it's a windows firewall issue since i cant acess the mi3g through 10.10.10.217 even on my android phone.
oh... well there is one other possibility... do you have wifi client isolation enabled on your main router? Let's see the config from that device...
Well, I don't think I do, unless it comes activated by default on owrt

No, client isolation is not enabled by default. And it's not enabled in your config, either, so that's not the cause of the issue.
Are there any other infrastructure devices in your network? Do you have multiple APs, for example? Or managed switches or anything like that?
There isn't. I have my ISP router as bridge and the AX3600 is connected to it on PPPoE.
All my devices are connected to the AX3600 (Only PC on the lan port and others on the 2.4g or 5g wifi)
Mi 3G is on another subnet and connected to the 5G wifi of the AX3600.
to be clear, you're talking about the lan interface of the mi 3g, right? I saw that it is using the address 192.168.1.1 for the lan. And the wwan network interface you said is on 10.10.10.217, right? And this 10.10.10.0/24 network is the main lan subnet, where your PC and android phone are located, correct?
One more thing -- are you by any chance running a VPN client on your phone and/or windows computer?
Exactly, MI3G lan is 192.168.1.1 and AX3600 lan is 10.10.10.10
Once I connected the MI3G through the AX3600 wifi, on wan, it got the 10.10.10.217 through DHCP.
My pc and phone are clients to the AX3600 and I'm not running VPN on them.
I even tried to put MI3G lan on 10.10.10.20, but it didn't received internet, as it was on the same subnet as the AX3600, and I couldn't download packages. (samba)
This is expected. Best to leave your Mi3g on a different subnet for its lan interface.
I see you have 6 devices shown in the DHCP leases there... that means you have 3 other devices that you haven't talked about. Are those phones/tables or computers or something else entirely (like IoT devices or printers, etc.)?
Can any of those remaining 3 devices ping the mi3g? Can the Windows machine ping any of the 5 other leases?
In order:

Sorry, it's in portuguese but it worked out.
Tried to ping the router on the laptop and still got the same message as I got in My PC.
So, got some news.
I've Plugged my PC into the 3G, and remove the 5g wifi and conected to the 2,4g one.
MI 3G received a new ip (10.10.10.216) and was visible on other devices this time..
Its the exactly same setup I did for 5G..
strange... I have no idea why the 5G network wasn't working. I will keep thinking about it, but I certainly can't explain that situation.
I see.. thanks anyway for your support. Sadly I really needed to use it in the 5g for better speeds, I'll see what I can do about that..
