Model: Archer VR900  
Hardware Version: V3
Firmware Version: 0.5.0_0.9.1

I've been experiencing issues with 2.4Ghz bandwidth. It's very unstable and often extremely slow. 

Our internet connection is 300/36Mbps and I can easily achieve those speed when connected to 5Ghz, but 2.4 is a disaster. It often disconnects devices and takes about 30-50 seconds to reconnect often stating that no internet connection is available (while 4Ghz network works perfectly fine) and speeds achieved drop to ranges of 0.5-2Mbps. 

It gets to a point where I had to forget the 2.4 ghz network as I am unable to work!

 

I know that my internet is stable as 4Ghz achieves full internet speeds. 

The router is updated to the latest firmware. 

There is nothing blocking it especially considering that 4Ghz works flawlessly

@IronCladHippy  Hello, 

 

If only 2.4GHz got unstable issue and 5Ghz WiFi works fine, please login web page and change 2.4Ghz Channel width to 20Mhz to reduce possible interference. 

Changing Channel and Channel Width on AC VDSL or ADSL Modem Router (new logo)?

Please try a different Wi-Fi channel on 2.4Ghz, 1/6/1 or a relative idle channel is recommended. 

 

If the same issue, may I know did 2.4 work fine before? What is the build number on modem's firmware? 

Is there any video stream, file downloading or large traffic network actives when this issue happens, what are the devices connected to 5Ghz and get unstable problem? 

Please let us know your current firmware and hardware version, thank you.

@IronCladHippy Hi and thanks for coming back to me.

I have changed the width to 20Mhz and will report in few days. 

No issues with 5Ghz and there are no large files being sent. Out internet is a 360/36, so rather sufficient for what we do (Teams, using office files online etc)

The router is rev 3 and 2.4 GHz used to work fine.
