Hi, I'm having a brand new Deck X50 5G and I'm trying to open the ports on my Xbox Series X, but I'm unable to do so. I've done everything I should have to do but it still says strict. What am I doing

It seems the M5 uses a wide 40MHz channel in 2.4Ghz mode instead of the recommended 20MHz. How can we change that? Also would be nice if we could to change the wifi channels in advanced settings. Will
