Netgear M7 pro unable to connect 5G in S.KOREA
Model: M7 pro (#MR7400)
Firmware Version: NTGX75_10.03.22.01
Software Version: MR7400-1A1NAS_02.11
Hardware Version: 1.0
PRI Version: 02.11
My device is an AT&T model but is carrier unlocked. Currently, I have registered the IMEI as an SKT 5G device in Korea and configured the APN settings for 5G. SKT Korea supports the 5G n78 band, and I understand that the M7 Pro also supports n78. However, the device only connects to 4G LTE, and 5G is not working.
How can I enable 5G? Do I need to register the device on an allow list, even though it is carrier unlocked? Or can I force the device to use the n78 band through firmware modifications or debugging? Please provide guidance on how to resolve this issue.

JohnPengHow do you know that n78 does not work? do you have a method that list the connected bands on the M7?
- I'm not entirely sure if N78 is not working, but even with manual carrier selection, my device only recognizes 4G (while Korean phones show very strong 5G signals in this area) and does not detect 5G at all. After searching various local forums, I found that some overseas carrier-locked devices may have a sort of region lock, which makes me suspect that N78 might be restricted. So, I'm asking if there is a way to force N78 activation or remove the allow list(region restrictions) through firmware modification or debugging.
rcpax JohnPengI don't have an M7, I have an M6, and I suspect the FW are probably working about the same way. If it's an ATT M7, which from what I know, is the only M7 in the market right now, then the 5G radio is very likely NSA mode only. SKT might be operating their n78 on SA mode, i'm not sure, or it could be both SA and NSA mode. I know the ATT FW has no SA mode in their 5G because ATT has no SA 5G implementation in the US, so very likely you can not force an n78 SA connection. When it's connected to 4G, your n78 5G could also be connected in NSA mode, but there is no way for you to tell for sure because the web GUI has no ability to display what specific bands are connected to the tower.
