I live in Korea. I purchased BE900 while traveling in Japan. Is there BE900 firmware for each country? Or is it integration? Will there be any problems using it? frequency, etc.

I am using be800 in Korea and would like to buy be900 sold in Japan Can I use the be800 adapter used in Korea as it is?

hello The router is TP Link's be805. I am inquiring about MLO connection. I am using 10 gigabit internet. When MLO is connected, 5G and 6G cannot be used together. Only 2.4G and 6G are used together.
