just check my asus router asus tuf-ax5400 router latest firmware is 388 and the memory usage still around 83-84% usage.

388 is firmware family

TUF-AX5400 is still on the older 388.21224 version released in late October

You need to wait for 21617 or newer which included the memory fix

ok got it thanks agaon.

388 have vpn fusion for wireguard on xt8. almost buy axe11000 to get this function.

VPN performance gap is very big

Almost 10x difference

Hi mroctopus,

Are you able to check whether the MAC address of the WiFi adapter is in the Wireless Log located at System Log->Wireless Log?

You can also just try key in the MAC address of the WiFi adapter to the bandwidth limiter and test it.

Try update the WiFi adapter driver to the latest as well.

Thank you

Hi all,

I need to find a replacement power adapter for an RT-AX88U at my parents house. I,’ve been searching onlne but not sure what is wattage (45w or 65W) and connector size (4.0mm*1.3mm or 5.5mm*2.5mm) comparible with the router. I’ve been getting different information from different websites and currently unsure which one to choose.

Appreciate if someone can help me on this. TQ

For Asus TUF AX5400 users, do you experience the router having slow wifi speed after few days turning on the router? I have to restart the router after a few days because the wifi download speed would drop to 8mbps download. Upload speed is not affected.

My unifi is 800mbps. After restart the router, the wifi is normal 800mbps download and 200mbps upload. But after a few days leaving it turn on, download speed is 8mbps and upload is 200mbps.

I already upgraded the firmware to the latest and hard reset the router. Can't seem to fix it.

I hardly restart my Asus router, connection is consistently at 800mbps unless there is network issue with TM. Maybe once a month i do a manual restart or when there is a firmware update then i am forced to restart. I am on GT-AX11000. Did you try calling TM on this?

2 options, either schedule daily reboot in system or downgrade firmware (until you find one that is stable), remember to do hard reset.

Had encountered this on old Asus router, after downgrade firmware no more slow download speed after a few hrs or days

I see. In my case, it's nothing to do with TM. I know it's the router problem. When it happens, I try to test speed with ethernet cable, it gives me 800mbps. But 2.4/5Ghz wifi only few mbps. I have to restart the router to get back 800mbps on wifi. I already changed the router to a new unit. Same problem.

Usually it happens after a couple of days. Already tried the stock and the latest firmwares, still the same problem. Hmm gotta try other firmwares. What a nuisance

Hi,

No issue here. Speed drop abit but not that drastic like yours.

Never encounter this low download speed on my router. Already on for 6 months uptime. Using ax88u btw.
What I think maybe the wireless chip overheat or bug then it slow down your wifi performance maybe.

This is strange, what’s your memory usage when this is happening


Have you replicated the test on other devices to isolate the problem?

@Asus MY



Available in MY already?
MSRP?

Anyone experienced 2x AX53U in wired mesh? Is it stable?

Memory usage only 63%

Tested on wifi 6 phones and wifi 5 pc and laptop. All the same problem. But if connect with ethernet cable, full speed. Have to turn off and on the router again to get full speed from wifi

Try this hard reset method, should fix 90% of the issues.

Wan to ask Asus support team
