AX88U will only connect at 80Mhz

[antik]

I previously had an AX3000 and my 2x2 AX laptop would always connect at 2.4Gbps. I’ve replaced the AX3000 with an AX88U, and I’m running the same settings, however my laptop will now only connect at 1.2Gbps.

I’ve got Wireless Mode set to N/AC/AX mixed, and Channel Bandwidth set to 20/40/80/160Mhz. It’s only when I force Channel Bandwidth to 160Mhz that I’ll be able to connect at 2.4Gbps.

Why won’t my laptop connect to the AX88U at 2.4Gbps like my AX3000 did, without forcing 160Mhz?

Would you benefit from 160MHz? All those LAN and WAN connections are only 1Gb, so unless you have a LAG(LACP) connection from your router to a NAS or similar you'll never notice the diference.

*edit* Mine will run 124/160 without fuss once the initial testing is done, but I choose to use 149/80 as it's all I need and the range is better.
