ASUS RT-AX86U local network WIFI Ping issue 388.1

[geoffroyg]

Hi,

I have 3 AX86U in Aimesh (wifi backhaul)

Since I upgraded to 388.1, I am getting a lot of short disconnect issue on WIFI, and also very slow ping to wifi devices on the local network. No issue on ethernet.

Anyone else experiencing this? If anyone has an idea of what could cause this?

I'm afraid most of us with RT-AX86U's are experiencing quirkiness with 388.1 - especially with AiMesh as a Node for this router model.
You will see from my signature that I have reverted to 386.5_2 firmware on both of my RT-AX86U's and am back enjoying rock stead and speedy service from main and node.

You only other option is to run 388.1 on the main router only - and then run Asus stock firmware on the AiMesh Nodes.
Sadly you will not get any support at all from the developer of Merlinware because AiMesh is closed source and beyond his control - as are all WiFi drivers and their bugs.

Thank you for your answer. I did downgrade to 386.5_2 and all problem solved. I found the issue, because I had to understand, what was causing those gigantic ping on my local network.

The answer is Guest Network. I was using a guest network and funneled it to a wireguard VPN. I wanted to have a specific SSID that would be directed to VPN. That caused the issue. I wanted to get rid of my other set of Aimesh routers specifically for that VPN... I guess they will stay for a while untill this is fixed.

 

[kernol]

Take note that on firmware 386.5_2 you must set "NO" in answer to "Intercept NTP client requests" on the Administration > System tab.

There is a bug in the coding which was fixed in 388.1 - but exists still in 386.5_2 and in 386.7_2
If you answer YES to intercept ... the redirection of Guest Networks to a VPN Client simply does not work.

For me it didnt worked. I have installed 388.1 on main router and Asus stock on AiMesh, but have same problems. So I believe only reverting both, router and node, to previous would be solution (will do that and check during next following days)

 

[brummygit]

Yes I have similar and found my AX86U nodes were dropping offline briefly even using stock firmware on the nodes and Merlin 388.1 on my RT-AX88U main router. There is something broken in 388 affecting the AX86U either with the Merlin main router losing the AX86U nodes, or in the stock AX86U firmware running as a node (more likely). I don't have the chance to run stock firmware to test on my main router as my network is awful without CAKE QoS.

I posted more info in this thread https://www.snbforums.com/threads/a...ing-with-new-firmware-when-downloading.82384/

 

[kkholimi]

My AX86U performance become erratic with latest Asus Merlin 388.1 upgrade. WAN speeds irregular, and wifi connections drops intermittently. Downgraded back to 386.7_2 and everything went back smooth steady.

I must wonder what it is that all of you experiencing problems are doing that I'm not. For one thing, my nodes are connected via ethernet. Before I wired my nodes, I found that 80 wide was much more stable yet I know part of the 160 wide issue is DFS use and my proximity to an airport.

When you downgraded, was did you have the router on the same channel as when you had the long pings? The pings you are showing are typical of a congested network or channel

Sorry to resurrect an older thread, but wondering if this might be similar to the problem I'm seeing on my network. I'm using 4 APs for wireless coverage. A AC86U for the main node and older AC68U for coverage across the house. All the AiMesh nodes are connected via ethernet for backhaul. The AC86U is then plugged into a 24 port unmanaged switch.

Main Node: RT-AC86U Current Version : 386.11
3 AiMesh Nodes RT-AC68U Current Version : 386.11

I have a linux server that is on 24x7. I have several wireless devices such as tasmota and a vacuum. The server can access these devices, and ping them no problem. However all other client devices (windows PC, mac laptop, iPads and iPhone) cannot access these wireless devices -- for a while? If I set up a ping, it will take 2-3 minutes, then it responds and I can pull up the web interface on the device. This issue has been driving me crazy, as it makes accessing my IoT wireless devices difficult and overly time consuming.

I see that 386.12_6 is out. Could this fix the problem, or am I better off reverting to 386.7_2 as mentioned earlier to see if that resolves the problem? Any help at all is appreciated as this is now a bigger issue as the robot vacuum can't be easily pulled up on ipads for a 'quick clean'

Please provide a network diagram for all switches and Asus devices. Your VLAN mapping and include the VLAN configuration for all ports that your Asus devices connect to and if connected as a host port or trunk port.

I have a very simple network. No VLANs. the internet is plugged into the RT-AC86U WAN port. An old Linksys SR2024 is plugged into port 1. The server and most other wired devices are also plugged into that 24 port unmanaged switch. My PC is plugged into the RT-AC86U port 2. Wireless devices are not immediately found on the Win11 PC, or other wired devices such as raspberry PIs. My ubuntu 22.04 server can ping all the wireless devices immediately just fine.

Just wireless devices take a long time to reach. Anything wired, I can access on any device immediately.

Now you don't mention the mesh nodes. They are hard wired yet where do they do they connect and what is the full path between the router and each noce? What status does the router show for each node? show the ping of each node.

 

[hp1]

Sorry, I missed that. the 3 mesh nodes are plugged into the SR2024 switch (I do also use the ethernet ports on the mesh nodes for plugging in a few local devices such as an nVidia shield). So full path to each mesh node would be AC68U <-> SR2024 <-> AC86U.

On the AIMesh screen, the Connection Quality to all 3 nodes is 'Great'. One weird thing, on the Network tab, the 'Backhaul Information' and 'fronthaul information' just shows 0's for transmit and receive rates.

The ping results look good as well:

Try moving all your nodes from the switch to the router. The retest and look at all status.

OK, I have 2 open ports on the router, so I'll disconnect all 3 mesh devices and plug 2 back directly into the router. The devices that are slow to respond, interestingly it's just inbound. if I go to the linux server and open up a web page on the tasmota device, I can operate it fine and it can connect to the internet. I have to ping the wireless tasmota device for 1-3 minutes from the windows PC/mac laptop (or reload the web page several times from an ipad) before it responds.

Looking at the clients page, another interesting item. One of the devices that I'm trying to connect to (192..168.0.20) doesn't show up in the client list. When I ping it, once it responds I can access it's web page:

OK, I have 2 open ports on the router, so I'll disconnect all 3 mesh devices and plug 2 back directly into the router. The devices that are slow to respond, interestingly it's just inbound. if I go to the linux server and open up a web page on the tasmota device, I can operate it fine and it can connect to the internet. I have to ping the wireless tasmota device for 1-3 minutes from the windows PC/mac laptop (or reload the web page several times from an ipad) before it responds.

Looking at the clients page, another interesting item. One of the devices that I'm trying to connect to (192..168.0.20) doesn't show up in the client list. When I ping it, once it responds I can access it's web page:

Please move all 3 nodes to the router. Even if you have to move a host from the router to the switch. We need know that the nodes all talk to the router and work properly or possibly not. If you have a laptop, wiring it to each node and pinging the router would be very helpful. If all of that passes, then pings from anywhere on your asus network across the switch will be very telling.

Can do. Will be a little later this afternoon, and I'll also ping the router and server from my laptop from all 3 mesh nodes.

OK, I plugged each of the AC68U mesh nodes directly into the AC86U router. I then used my laptop with wireless and then wired to ping the router. The results:

After all of this, I wanted to see if the problem of accessing devices went away, and alas it did not. from my wireless laptop, I tried pinging 192.168.0.20:
