I chose the 620 S as a replacement for the difference; there was also an Asus 570 with 5G, but it does not support 4G; to summarize, I am very happy with the purchase due to a combination of factors))) Has some pros: 1. 5G is awesome 2. After tuning, the 2.4 also functions perfectly and is an improvement over the 620S 3. The 4G modem with the HiLink firmware functions without any issues. 4. Easy configuration (I didn't change a thing, and everything is working))), with the exception of the wireless network. 5. 24/7 support service! important 6. prices that are, on average, not prohibitive Got cons: No major grievances, just these tiny things: 1. The selection of channels for 2.4 must undergo a minor tweak; for some unknown reason, it does not function particularly well on the system. 2. I purchased a router that had some sort of firmware installed on it, but I was unable to access the router's configuration page. After I updated the firmware, everything started functioning normally again.
