RT-AX88U - MacBook Pro doesn't work with WiFi 6 enabled

Hi all!

I have a MacBook Pro 2019, Intel i9, sent by my employer. My issue is the wireless connection keeps disconnecting very often when 802.11ax is enables on my Asus Router. The only way I found to have stable connection was to completely disable 802.11AX, aka WiFi 6.

I really would like to have it enabled, as I have a few devices at home compatible with WiFi6, including my smartphones and wife's Dell notebook.

Did anyone face that issue? How did you fix it?

You need to check the specs on the system.  If it shows what is shown below, it is not Wi-Fi 6 compatible since 802.11ac is only Wi-Fi 5.

I don't have any devices that are strictly Wi-Fi 5, but they should work fine with that router.  That being said, there have been some discussion as to a MacBook Pro possibly being a little different when it comes to Wi-Fi operations.

If your company sent it to you, maybe you could use the problem to get a newer version of the MacBook Pro. 😉

Hi @Saltgrass !

Thank you for your reply. After some checks on ally devices, I found my LG laundry machine can't connect either when WiFi 6 is enabled. But I can live without a WiFi laundry machine, lol 

I'm going to open a ticket at ASUS.

Try WPA2/WPA3 Personal please.

Hi @jzchen .

I already tried WPA2/WPA3 Personal, and WPA2 Personal only settings. The problem didn't change.

Also check OFDMA/802.11ax MU-MIMO as it even seemed to cause trouble with 6e devices.  Try fully disabling I would suggest...

Hi @jzchen . It was already disabled. Same issue.

I had the same issue a few months back and thought of getting a new router but I troubleshooted the router and now my wifi is stable on my macbook and never disconnects. Try updating your mac, deleting your wifi password, re-adding it, also try resetting your router, if that doesn't work then use an external wifi adapter and check. I am sure these troubleshoots will fix your wifi disconnecting problem.

Hi all,

A complete factory reset on the router fixed the issue. I contacted ASUS support, and after investigating the logs and content I sent them, they found that my router was using a cache for a firmware version different from mine.
