ASUS RT-AX88U Firmware v3.0.0.4.386_41249

[sanke1]

Running this firmware since 3 days.
Solid 23hr PPPOe DHCP sessions with my ISP.

• No random PPPOe disconnects and even Ethernet Backhaul to another RT-AX88U node is going strong.
• Devices are roaming correctly with no Wifi dropouts.
• Transfer from my NAS to iPhone started with solid 72 MBps (576 Mbps) from one end of the house connected to node first. Then I moved about to the other end which has main RT-AX88U and transfer speed over Wifi did not go below 55 MBps (440 Mbps). The whole 20.1 GB file downloaded from my NAS to the iPhone (Qnap's QFile app) in 5 min 42 sec at average transfer speed of 60 MBps. Connection between AI Mesh system and my iPhone remained at solid 866 Mbps throughout

So is this stable enough to update over the previous fimware?

I'm going to roll back to 384.9579 I think. Ever since I updated to 386.41249 my 5G has been cutting out. ALL of my 5G clients will drop at the same time. ALL 2.4 clients remain connected.

The same thing happened to me ... my 5G was interrupted.

The same thing happened to me ... my 5G was interrupted.

I went into 5G Wifi settings and I switched off "enable 160 MHz" and changed the Control Channel to AUTO which had been 40 before (based on some testing I did months ago). I'm not sure if this is what did it, but so far I haven't had any 5G disconnects (after about an hour).

160 MHz bandwidth uses DFS channels subject to disruption. I would use fixed, least congested, non-DFS channels (36-48, 149-161) at 20/40/80 MHz and live with less throughput but more stability. When WiFi 6e arrives, go crazy with 160 MHz in the 6.0 band.

Thank you for the advice. I switched back to fixed 40 and kept 160 off. So far 5G is stable. This is with latest firmware.

I would like to report:

I have been running smoothly with Stock 3.0.0.4_386_41249 for about 2.5 days, my configuration includes using only AiMesh 2.0 DEFAULT settings:

• Solid Ethernet Backhaul
• Excellent Wifi (AiMesh Roaming/Steering)
• Good Performance (Upload/Download: Wifi (ac) about 400mbps, Wired about 930mbps)

Hope that it can be a useful comparison for others with similar configuration.

My Configuration:

• AiMesh Router: AX88U 3.0.0.4_386_41249-g66dde88 + 2 x AiMesh Nodes: AC86U 9.0.0.4_386_41157-gd618756
• Backhaul (Priority:"Auto", Type:"Wired"), Asus GX-U1051 5-Port Gigabit Switch from Router to Nodes, ISP: 1 Gbps Fibre

My steps to Upgrade from Merlin 386.1_beta1 -> Stock 3.0.0.4_386_41249:

(1) Upgrade AiMesh Nodes:

• Administration -> Upgrade Firmware ->
  • Select and Upgrade AiMesh Node (One Node at a time)
• AiMesh -> Topology -> Select AiMesh Node ->
  • Remove Node (One Node at a time to Factory Reset Node)
• Note that I use Beta FW AC86U 9.0.0.4_386_41157-gd618756

(2) Upgrade AiMesh Router:

• Administration -> System
  • Format JFFS partition at next boot: Yes
  • Enable JFFS custom scripts and configs: Yes
• Reboot: GUI or Physical with WPS button
• Disconnect LAN Cable from MacBookPro (to get a new IP address)
• Administration -> Upgrade Firmware -> Select and Upgrade
• Factory Reset with GUI -> ie. Restore with the (X) Initialize option
• Configure from scratch
• Reboot : GUI or Physical with WPS button

(3) After Full Factory Reset of AiMesh Router / Nodes, I tried to leave NVRAM using Stock FW default values, except with the following changes:

• Enabled AiProtection: ON
  • Malicious Sites Blocking: ON
  • Two-Way IPS: ON
  • Infected Device Prevention and Blocking: ON
• USB Application
  • UPnP Media Server: OFF
  • Samba Share: OFF
• Wireless:
  • 2.4 GHz: Fixed Channel Bandwidth 20MHz, Fixed Control Channel: 11, Explicit / Universal Beamforming: Disable
  • 5.0 GHz: Fixed Channel Bandwidth 80MHz, Fixed Control Channel: 149
• WAN DDNS:
  • Using Asus DDNS Service with Let’s Encrypt (Let’s Encrypt appeared to be not working lately, Workaround: so I turn HTTPS/SSL Certificate to NONE and just use HTTP to access my router)
• IPv6: Enable
  • Native (Understand that VPN Servers on ASUS does not support IPv6; therefore, DNS Leaks (OK for me, as I only occasion use it to remotely manage Router for a short while when I am outside))
• VPN Servers (Connecting one at a time from the following clients):
  • OpenVPN works with MacBookPro Tunnelblick 3.8.5beta0, iPhoneXsMax iOS OpenVPN Connect 3.2.2
  • IPSec works with MacBookPro & iPhoneXsMax Native Configurations
  • Instant Guard works with iPhoneXsMax iOS Instant Guard 1.0.9

(5) Add AiMesh Nodes

(6) Reboot AiMesh Network (for a clean AiMesh Restart )

• AiMesh -> System Settings -> Reboot (AiMesh Router & Nodes)

Hi, I would just like to update my report that my configuration has been running smoothly for the last 5 days. Thank you.

is 40Mhz not small
i have it on 20/40/80Mhz (fixed channel 100)and i get around 600Mbps with my iphone XS. i doubt if i get the same throughput if i lower it to 40Mhz
80Mhz should be as stable as 40 Mhz since it does not travel far

Thank you for the advice. I switched back to fixed 40 and kept 160 off. So far 5G is stable. This is with latest firmware.

If you set it for 20/40/80 MHz, it will use 80 MHz when possible and not use DFS channels if you do not set DFS channels. 100 is a DFS channel in North America.

the first part i get but the second part not.
100 is also a dfs channel in the netherlands

so it clearly works on 100 but do i have 80Mhz?

this is what i see

It says you are using channel 100 at 80 MHz.

But if DFS kicks in to avoid interference with other non-WiFi DFS channel users, your radio will change channels and your clients might feel it.

Keep what you have, if your clients are happy.

I prefer to stay off DFS channels here and be done with it, since non-DFS channels work at AC 80 MHz. 160 MHz can't avoid using DFS channels on the 5.0 band.

Sorry, I was unclear. I switched back to channel 40 and turned off 160Mhz mode, so it's running at 80Mhz

 

[liqiang2020]

how i can change the default port 81 to any other port? (192.168.50.1:81)

 

[L&LD]

81 isn't the default port, is it?

 

[liqiang2020]

81 isn't the default port, is it?

default for http by wifi

 

[L&LD]

I don't think so.

liqiang2020,
Like L&LD I have not encountered the issue you faced be it Wired or Wireless. From your 5 posts it is not clear how you setup your Router. May be you want to consider doing Factory Reset and reconfigure you Router from scratch (without restoring old configuration) with minimum basic Router settings. Hope you find a solution for your configuration.
