Hi mrhaav,

Is your mr200 v4 a free version or isp version?
I have an orange spain version, and after instalingl the 210201 stock firm with the tftp method, don't work the wifi or 4G.
Both macs don't match, so I need a full stock v4 dump to try to fix it. Can you make a full dump and share it? Before flashing it, I will change the wifi and 4g macs on the dump, as it is done with the dump file of the v1.

Thanks

Hello, I have the same problem, isp orange Spain, openwrt after x days the connection is cut off, I want to put the original tplink firmware but when I come back neither wifi nor 4g works.
Is there any way to fix it?

thank you.

@guillep84

openwrt after x days the connection is cut off

so bring it back up, if it goes down ?

@frollic

so bring it back up, if it goes down ?

I need restart router and works again for a few days.

[frollic]

then script it ?

and it's probably your ISP cutting the connection, not he router itself.

I just did a clean configuration, I put the two scripts, uqmi_led.sh and uqmi_sms.sh with version 19.07.8 with uqmi_2022-04-22-0.5.
I'll wait a few days to see if it doesn't cut.

If I install uqmi_2022-07-14-0.8 it never connects to 4G, is there a problem?

Can openwrt version be upgraded to 22.03.2? I downloaded the file openwrt-22.03.2-ramips-mt7620-tplink_archer-mr200-squashfs-sysupgrade.bin but LUCI tells me:
"Device mr200v4 not supported by this image Supported devices: tplink,archer-mr200 mr200 Image check failed.

The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform."

If I force it, it won't boot and I have to reconfigure everything.

Thank you.

Hi
What do you have in the syslog when you are disconnected with uqmi_2022-04-22-0.5 and what do you have when you are using uqmi_2022-07-14-0.8?

Can you try to re-install uqmi?

wget http://github.com/mrhaav/openwrt/raw/master/19.07.8/uqmi_2022-07-14-0.8_mipsel_24kc.ipk
opkg install uqmi_2022-07-14-0.8_mipsel_24kc.ipk --force-reinstall

I just did the same on my MR200v4 and it´s ok.
