ASUS USB-AC56 wireless AC1300 Cannot 5GHZ, slower than rated.

Go to solution Solved by fpo,

I got it working. I had to change the channels to 1 for 2.4 ghz on my router & channel 44 on the 5 ghz.

I bought this ASUS wifi adapter & it's having a few problems on Windows 10 64 Bit.

Sometimes it will detect the 5GHZ network, & other times it doesn't. When it detects the 5GHZ network, it cannot connect because "Was the password incorrect?"

I logged into the router to double check the settings.

2.4GHZ

5GHZ

It came with its own WiFi connection software. I think I have the latest version of the software at 2.1.1.5. From the website I got a lower version with for some reason more buttons at 2.1.1.2.

Current installed 2.1.1.5

When I connect to the 5GHZ WiFi network, I can click on the configuration tab & sometimes see the 5GHZ version.

I tried to connect via WPA2 personal with AES, TKIP. I don't understand the other connection methods.

In that Infrastructure button above "Network Name (SSID)" I think there's supposed to be a second option to select.

 

I also tried selecting 802.1x. Idk much but I'd think that's the fastest connection method based on the writing of the WiFi adapter on the box. I have no idea what most of this mean & we don't have a username password wifi system setup

It's disappointing to see it scoring as low as 85 down and 90 up. The device is said to be rated to do 400 mbps on the 2.4 GHZ network.

This adapter was $70 & manufactured in 2020.

My other Linksys adapter that is 1/3 the size and only cost $35~ can score 200 both ways & is connected to the 5GHZ network. (I've been swapping to see the difference in speedtest scores.)

 

Other diagnosis is removing the antenna, switching from the USB 2.0 port to USB 3.1 Gen 2 port.

 

So my questions...:
1. Why can I not detect the 5GHZ network on this new adapter?

2. Why is it ill able to connect to the 5GHZ WPA2 AES encription when the router's 5ghz network is configured as such? I double checked the password.

3. Should I connect via another method? If so what?

4. Anything else I should know?

 

I bought this because the guy at micro center recommended it & he said it works with Linux. I am currently on windows 10 64 bit. I will switch to linux at a later date.

Im not sure where you said the device is for the router. If its in the same spot as the previous one and getting much worse then your older one, id see what port you are supposed to use.

 

IMHO get rid of the software, it tends to be garbage. Just use the normal means of connecting to wifi.

 

Certain devices are super finicky when it comes to 5 Ghz and certain configs without the proper authentication will spit out errors.

 

Id 100% triple check the password, or do a simple quick reset and see if that fixes it.

wdym port? The devices were in exactly the same spot & the same ports.

You mean this method? It doesn't show the 5GHZ for me there either. Is there something else I can do?

Where else can I check configuration & authentication? Still in that menu where it said "please check you have entered the correct password?"

Already done so. Restarted my PC several times, repairing, uninstalling, reinstalling, repairing, restarting router.

 

 

Thank you for your help. Do you have any further advice?
