Does not connect to Wwan0 device

vanessa · February 7, 2024, 9:13am

I'm using a translator.

I connected to the Internet from the modem using the mbimcli command in openwrt. The IP address starts with 10. The rest is received randomly each time. (ex. 10.210.198.20)
The name of the device is wwan0.
If I specify wwan0 as the default router, the Internet will be connected.
However, when I connect to Wi-Fi, it says that the Internet is not available.
With pathping command, it only connects to 192.168.1.212 > 192.168.1.1 (OpenWrt.lan) and does not reach wwan0.
How do I solve this problem?

move wwan0 to the wan firewall zone ?

AndrewZ · February 7, 2024, 9:16am

Make sure the interface is a member of wan firewall zone.

vanessa · February 7, 2024, 9:27am

The interface below uses wwan0. The firewall-zone of the interface is set to wan.

frollic · February 7, 2024, 9:28am

is now, or was ?

vanessa · February 7, 2024, 9:29am

It's now.
Still can't use internet via wifi.

vanessa · February 7, 2024, 9:30am

I can use the Internet using a modem. However, Internet use is not possible on devices connected to Wi-Fi.

frollic · February 7, 2024, 9:31am

restart the network service, or reboot the device.

vanessa · February 7, 2024, 9:43am

I tried restarting several times, but the problem was not resolved.
The picture above is the result of the ifconfig command and you can see that ping is working well.

AndrewZ · February 7, 2024, 9:44am

Can you access Internet from devices connected to LAN?

Please do not use pictures when you need to show just text.

vanessa · February 7, 2024, 9:44am

This is the result of the pathping command from a laptop connected to Wi-Fi. It disconnects after arriving at br-lan. Internet use is not possible. How do I solve this problem?

vanessa · February 7, 2024, 9:45am

sorry. Because it was a different laptop, I couldn't express the results in text. I confirmed that when connecting to the Internet via LAN, the Internet is connected through WiFi as well.

AndrewZ · February 7, 2024, 9:50am

Sorry, I do not understand this. Do you have a problem with Wi-Fi clients only or with both LAN and Wi-Fi?

frollic · February 7, 2024, 9:51am

might be a good idea to ....

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Current

modem(wwan0)-OpenWrt(laptop)-(LAN cable)-PC

This connection will allow me to connect to the Internet.
However,

modem (wwan0) - OpenWrt (laptop) - (WIFI) - PC

this connection, I can't use the Internet on my PC.
In both situations, Internet access is possible on OpenWrt (laptop).
How can I use the Internet on other devices connected to Wi-Fi?

vanessa · February 8, 2024, 1:08am

I couldn't think of a way to use ssh. thank you for telling me.

If this is true:

Cannot do this:

This is wrong:

vanessa:

config interface 'wan'
        option device 'wwan0'
        option proto 'static'
        option ipaddr '10.241.130.121'
        option netmask '255.255.255.0'
        option type 'bridge'
        oprion dns '8.8.8.8'

Should be dhcp client

This is wrong:

vanessa:

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'wan'
        option mode 'ap'
        option ssid 'OpenWrt'
        option encryption 'psk2'
        option key 'tspdi@205'

Needs to be client not ap.

I do not config in CLI; someone will need to rewrite those mistakes for you.

LilRedDog · February 8, 2024, 1:29am

This whole problem is so close to this I feel like this is homework for some class.

vanessa · February 8, 2024, 2:08am

Change the wifi mode from 'ap' to 'client', the wifi 'OpenWrt' is not searched. So it won't connect from my PC with wifi.

I changed wan's proto from 'static' to 'dhcp'. There was no change.

This whole problem is so close to this I feel like this is homework for some class.

I've read it, but it seems different from the problem I need to solve. I am trying to connect 5G internet through usim and spread it through wifi.

LilRedDog · February 8, 2024, 2:15am

Your laptop has one radio. It may do both 2.4 and 5, but one all the same.

So, you need to use it to connect to wwan.
And that is it, all you can do is use the ethernet for lan on the laptop.

You can try a USB dongle and we have a thread looking for a reliable one but nothing is reliable enough to recommend yet.

Assuming

Is what you have to work with.
