Archer MR200 v6 cannot connect to Play network in Poland - fixed

Used Products:

Bought a brand new Archer MR200 and a SIM card from Play.

 

Tested the SIM card in a phone to make sure it works.

 

The modem kept on disconnecting with the following errors in the log and would show IP and DNS as 0.0.0.0:

 

USER: Start connecting to the network! 
USER: GetCurrProf result is:ipver:2 staticApn:0 authType:2 pkgName:PLAY profname:PLAY apn:internet usr: psw: 
USER: Get ISP's profile now. 
ERROR: Verbose Call end reason = 2001 , type = 3. 
ERROR: Call end reason = 3. 
ERROR: OxOOOOOOOE QMI_ERR_CALL_FAILED
ERROR: Verbose Call end reason = 2001 , type = 3. 
ERROR: Call end reason = 3. 
USER: Dual Stack meet Call Fail, reattach 
ERROR: Verbose Call end reason = 33, type = 6. 

 

Did the following steps to make it work:

1. Upgraded firmware to Archer MR200(EU)_V6_230311 (https://www.tp-link.com/pl/support/download/archer-mr200/#Firmware)

2. Configured 4G only in the network options

3. Manually added a new network profile - copied everything, but changed PDP to IPv4 instead of IPv6 and IPv4

The modem would also work fine when setting to 3G only, but then the speeds were only around 3-4 Mbit/s. After applying the 4G settings above & putting it outside the window, speedtest.net measured about 20-30 Mbit/s and the connection was fairly stable.

Hello!
  I changed the password on my router and now I can't see the network when the wifi is turned on. I've tried all kinds of options. Diagnostics, restart, but the network is hidden. How to find it?
Thank you!

 

We use A1_F72D
and A1_F72D_5G (as from 5G we draw the main link).
Please help.
