Question m.2 2230 WiFi card that can do 1300Mhz on AC?

[jrichrds]

I have an Asus RT-AC68U router which is 3x3 AC1900 (1300mbps on 802.11ac).

I've been having a hard time figuring out what m.2 card can get 1300mbps on Wireless-AC on my HP i5-8400 (H370 chipset) PC.

The Intel AX200NGW seems to be the popular card right now, but I can only find info on max AX speed and not AC speed.

Any advice on what my choices are?

according http://en.techinfodepot.shoutwiki.com/wiki/Intel_Wi-Fi_6_AX200_(AX200NGW)

AX200's ac speed can be up to 867 Mbps. You will be lucky if you can get half of that.

Thank you! It looks like no m.2 WiFi card is capable of more than 867mbps on AC.

The speed that any device can do on wifi is based upon the frequency and the number of supported radio chains. Also let me preface this and say only a total asshat moron would run anything past a 40MHz wide channel on ac or ax with a 5GHz channel. Unless you live on the moon or in a corn field Iowa, running anything other than a 20MHz or 40MHz wide channel fracks up wifi for all who use it.

The link lists the radio at 5Gz 160MHz wide channel hits 2402Mbps @1024QAM for .ax at .8 microseconds (us) guard interval To get AC rate so you look at the MCS table and go backwards. .ac only uses 256QAM so at short guard interval .4us that is MCS rate 9, thats 400Mbps for 40MHz wide channel, 866.7Mbps for an 80MHz wide channel and 1733.3Mbps for 160MHz wide channel. In practice the you will never achieve that throughput as wireless is half-duplex so expect less than half the stated throughout be happy if you get between 100 and 150Mbps.
