Hello, for my parents' home, which does not have fiber access, I would like to buy a 4G+ router to replace the one provided by the operator, which is of poor quality.

This operator offers 4G+ LTE band aggregation, so I want to purchase a router that supports this feature to provide them with the maximum speed possible.

I found two models on your website and the market: Archer MR600 and Archer MR505.

When comparing the specifications, I do not notice any significant difference. Therefore, I would like to ask: which model do you recommend? My primary need is to achieve the best possible speed on 4G+. Wi-Fi coverage is not important to me since I plan to use only the LAN port to connect the router via cable to a Wi-Fi 6 access point.

Are the interfaces on both products the same?

Do both products allow you to select the bands to aggregate?

Thank you !
