Asus AX88u slow on 2.4ghz wifi on certain devices

[Zacharybinx34]

My issue:
Wifi is extremely slow on phones on my 2.4ghz wifi network, getting only 5-7mpbs on speedtest. My Macbook Air gets 154.89mbps on speedtest.

All devices on the 5ghz are fine. But most devices on the 2.4ghz are extremely slow. I have the 2.4ghz set to the default settings.

I am running the latest 3004.388.8_4 firmware.

What I tried so far:

• I tried unplugging all ethernet devices.
• I tried unplugging my USB disk from the router.
• I tried numerous different settings and variations.
• I even did a full factory reset/wipe and reset up all settings from scratch.
• I changed the channel and scanned it to make sure there were no conflicts.
• I forgot the network on the phones, reconnected, etc.

I have 2.4 GHz devices that can't go on the 5 GHz network.
Any suggestions would be greatly appreciated!

Go to System Log, Wireless Log, look at RSSI value for the slow devices. Perhaps they are too far from the router.

I was literally standing right next to the router through.

Are you talking about MBps or Mbps? Makes a huge difference.
