Wi-Fi calling issues with Ai-mesh (on RT AC68Us)

[Zigzag]

Hi I do hope someone can help.  I’m using a RT AC68U as a Ai-Mesh router and a DSL AC68U (also configured as an RT AC68U) as an Ai-Mesh node.  My mobile, a Samsung S8, is setup with Wi-Fi-calling, which works well if I stay within range of the Ai-Mesh device that effectively first deals with a Wi-Fi routed call.  However, if I walk around the house whilst on such a call, I can experience a sudden, total loss of sound – that’s to say I can longer hear the person I was speaking to.  I’m guessing, but I think this may be due to me to stepping beyond the range of one of the Ai-mesh devices, and going into the range of the other.

I read somewhere that this is apparently a known issue with iPhones and allowing port forwarding on UDP 500 and UDP 4500 on the internal IP address assigned to the phone may help.  Despite my phone being a Samsung I’ve set my router with these port forwarding rules, though I’m unconvinced as to whether this has improved things.   Incidentially,  I’ve left my WiFi settings unchanged, so all the bog-standard default values still apply for both the 2.4 and 5 Ghz bands, and I tend to use the 5Ghz for my mobile.

Does both Node and AiMesh Router have same Wifi name, (they should do)

Your Android Phone, (S8) is it upto date and is the wifi calling using standard Android wifi calling seetings (no app)?

last question, are both Routers running the same firmware version?

For WiFi call and Skype and  video issue, Could you try to disable  – LAN > Switch Control > NAT Acceleration if available?

I am initially thinking that the converted DSL-AC68U is the likely cause as it is set up as Node,  maybe an option to make the DSL-AC68U (prime) and RT-AC68) as node. (more of a workaround, rather than fix) ;-)

Many thanks @uk-sentinel for your prompt post, with good suggestions, and apologises for being slow in terms of getting back to you.

Yesterday, I changed my setup back so that the DSL-AC68U is once again acting as a DSL, Ai-Mesh router and the RT-AC68U is the node again.  I ran into problems in restoring the full capabilities of the DSL-AC68U and time, as yet, hasn’t allowed me to explore further my Wi-Fi calling issues.  However, I thought it would be still a good idea to come back to you – here goes:

~ Yep, I initially configured the wifi settings etc for the Ai-Mesh router, then reset the other RT-AC68U and used Asus’s web UI to automatically configure that as the node – and this process assigned it with the same wifi  name.

~ My answer to those question is ‘yes’ and ‘yes’.  I’ve recently updated the phone with the latest firmware, which is  Android 9.0 Pie One UI.

~ Yep, formerly both the router and node were running the most recent firmware for the RT-AC68U, version 3.0.0.4.384.45149

~ I made this change in the former setup, but I’m unsure whether it made any difference in respect of wifi-calling.  I intend to explore this further now that the DSL-AC68U is once again acting as the Ai-mesh router

~ That’s one of the reasons why I opted to convert the DSL-AC68U back to being an Ai-Mesh router.

Ultimately, I realise that I need to conduct further testing in respect of this WIFI-calling issue and any further comments and/or suggestions would be most welcome.

It is a learning curve for us all, let us know how your testing goes ;-)
