Accessing OpenWrt Configurator using WiFi

falithurrahman · April 19, 2020, 7:57pm

Hello, i installed OpenWrt on my TL MR3420 and i followed this tutoral to give internet acces to my WiFi. When i haven't applied the tutorial, i still able to acces OpenWrt configurator through 192.168.1.1 on my WiFi network. But after i apply usb tethering, i have to connect my PC to LAN port available at my router, then set the IP to static. Then i am able to access the configurator. I tried to set IP of router through br-LAN interface but it always says failed and reverting changes.

Can someone please tell me what happened? I am pretty new to OpenWrt so some of the setting is still on default. Thanks before

It's been 4 days and i've read several reference. I tried to change IP with ssh like tutorial here, but it's no success.

I read that this happens frequently, i also found it here. Is there no one able to help me? Thanks...

Not sure what you have now I'd suggest starting over is the most straightforward course of action.

Reset the router to defaults then connect to a LAN port with a cable and set up a wifi AP. You should not have to change anything related to the LAN network, and it should always work to connect by Ethernet or wifi and log in to 192.168.1.1.

Next you'll have to temporarily connect the router to the Internet some way so you can install packages. Since you have a smartphone you can activate its wifi hotspot and connect to that. Go to wireless settings and create a new interface of mode Client. Enter the ESSID that is the network name on your phone. Pull down the Network and connect to WAN. Click the Encryption tab and choose WPA2-PSK and enter the key configured on the phone. Save and apply all of that then go back to Network--Interfaces and you should see there is an IPv4 from the phone on the WAN network. If not, edit the WAN network and make sure your new wifi client is the physical setting, and the "bridge" box is unchecked.

Being connected to the Internet, go to the software page and update the list then find and install kmod-usb-net-rndis. You can now take down the wifi connection to the smartphone by disabling the client interface on the main wifi page. It is important to do this before turning off the phone hotspot, because the main wifi on the router will go down if the client is enabled but loses contact with the phone.

Turn off the hotspot and connect the phone with a USB cable then enable USB tethering in the phone's settings menu. Go to Network-Interfaces-WAN again and change the physical setting to usb0 which is the phone. You should now have Internet again.

I've already reinstalled openwrt firmware on my router to make fresh start.

Like you said, it works after i installed fresh firmware. But even if i used fresh firmware, i can't change static IP on my br-lan interface.
The solution over here advise to connect via SSH which i did successfully. But after i changed IP through SSH, the router become inaccessible again. Do you have any suggestion?

eduperez · April 25, 2020, 9:30am

What are you changing exactly?

falithurrahman · April 25, 2020, 10:00am

I tried to change static IP on my router. But it's done now.

According to solution over here, i need to edit /etc/config/network file. So i installed nano, edit static IP within the file and restart the router. Then the static IP is successfully changed.

It is said that there is a emergency revert feature in version 18 that will go back if the web GUI cannot be reached. Change through CLI as the official reference is also no use.

Thanks for replying.

vi works too - didn't have to install anything, FYI. You could have also edited the backup and then restored it.

Sure it works, as long as you don't knowingly make changes to loose connection...or if you go to the IP within the revert window; or you actually select the option to apply the changes anyway.

That's just one function, BTW.

EDIT: I had note how interesting it is that all of the threads about "I changed my IP now I can't reach my router - I think it's bricked" have practically been replaced with threads like this.

falithurrahman · April 28, 2020, 11:24am

yup, vi also works but i prefer nano.

I've tried it more than 10 times but none of them works.

But after i changed IP address, i am unable to access UCI configurator unless i use LAN cable connection. Do you have any idea how to figure it out? Thanks

Hegabo · April 28, 2020, 3:21pm

I'm not entirely sure what a UCI configurator is, but I presume you are not able to access the router (via WiFi I imagine?).

Please post here the output of the following commands, copy and paste the whole block:

uci export network; uci export wireless; \
uci export dhcp; uci export firewall; \
head -n -0 /etc/firewall.user; \
iptables-save -c; ip6tables-save -c; \
ip -4 addr ; ip -4 ro ls tab all ; ip -4 ru; \
ip -6 addr ; ip -6 ro ls tab all ; ip -6 ru; \
ls -l  /etc/resolv.* /tmp/resolv.*; head -n -0 /etc/resolv.* /tmp/resolv.*

Please use the "Preformatted text </>" button for logs, scripts, configs and general console output.

Please edit your post accordingly. Thank you!

You must have separated WiFi from the LAN bridge (which allows LuCI access by default)...somehow...?

OH...yea, WT% is that?

Maybe it means "lost SSH access"?

Yea, we need configs.

ya, your assumption is right. i am unable to access router via wifi.

How can i check if the wifi separated from lan bridge?
Thanks

lleachii · April 28, 2020, 6:17pm

It's not separated, as long as 'OpenWrt' is the SSID you used.

falithurrahman · April 29, 2020, 8:05am

What if i want to change the SSID? Is there any way to make it not separated?
I tried to change the SSID and i am unable to access router via wifi anymore

Here is the wireless setting

I don't see much difference in config wifi-iface 'default_radio0' before and after i edit the SSID beside there is a key and encryption. Then, could you please tell me how can i check if the wifi separated from lan bridge? Thanks

Sure, just make sure it's an SSID connected to LAN...or you edit the SSID that already is.

Based on my configuration, the SSID is already connected to LAN, isn't it?
That's strange, how come i still unable to access my router even i already connected to wireless network.

When your PC is connected to the WiFi, what IP does your PC get?

Try changing this interface to be small letters only. Make sure you do the same change for all instsnces of the name on the different configurations such as firewall.
