TL-MR3420 3G\4G how to lock 4G and use only 3G
sorry, I use a translator.
the problem is that the communication tower gives 3g stably, but the router often tries to use 4g which does not reach my country house well. In the settings there is no way to use only 3G. Tell me, can there be special firmware or maybe a script to block 4g reception. thanks
