I recently installed openwrt on my Netgear r7800. After configuring the 5ghz wifi ( mode AC, channel auto ,width 160mhz) I noticed the internet speed lower than usual, +/- 200Mb/s slower.
After some investigation, it seems that even after selecting 160mhz width, it shows as 80mhz on my PC wifi info.
I tested messing with the country wifi settings (it's on PT normally, my country), but it behaves the same on other configuration.
Is there anything that I'm missing or its some sort of bug?
