Looking for a great deal on a new ASUS RT-BE92U Wi-Fi 7 router

Been looking at bit more, seems the BE86U might be better? even thought be92u is higher number and has 6ghz as opposed to 5gb. Can’t see the spec page: https://www.asus.com/uk/networking-iot-servers/wifi-routers/asus-wifi-routers/rt-be86u/techspec/

Anyone know if this model has sip pass-through?

It seems to also have guest network pro which need to look more at.  Any one know a USB dongle that is compatible so it would auto switch to usb dongle if broadband went down and switch back to broadband when it came back up?

I’m guessing this is a newer version of the rt-ax86U/S model?

Thanks

Kevin

Starting from firmware version 3.0.0.6.102_35404, the name will change from [Guest Network Pro] to [Network].

The RT-BE92U does have ‘Network’ as does the RT-BE86U,  ‘sip pass-through’ is standard on all ASUS routers as I remember my older RT-AC86U also had this option.

I cannot see and VLAN options on my RT-BE92U, but I believe you are correct that the RT-BE86U supports VLAN ID’s on the LAN which maybe better suited for your requirments.

Thanks, from looking the rt-ax86 doesn’t seem to have sip pass-through:-

NAT Passthrough : PPTP Pass-Through, L2TP Pass-Through, IPSec Pass-Through, RTSP Pass-Through, H.323 Pass-Through, PPPoE relay

That’s all it has.  Yes, be86u might be better, bit higher price at around 260…. I presume can turn off leds like on my ax86u albeit it occasionally they come back on for no reason but not happened for a while.

Yes price was one of the factors in which I chose the RT-BE92U for only £169 and has ASUSWRT-Merlin support

I have no need for VLANS etc, and subnetting for IoT/Guest is good enough for myself, mine has ‘Enable LEDs’ option so I am sure the RT-BE86U will also.

FYI: ASUS RT-BE86U at Currys is £209.00

Thanks, currently looking at the BE86U, one thing, it only shows WIFI data rates for WIFI 7, not a/b/g/n/ax etc, it implies it support those but doesn’t show the data rates, same for the be92u…

I’ve been checking nest thermostat and it only connects to 2.4ghz WIFI on a/g/n so need to make sure that definitely works and is supported.

I think if I go for it, I’m going to setup the WIFI differently… i.e. Guest WIFI – same as existing, main WIFI 2.4 – same as existing and then setup a separate main WIFI 5ghz. Also BE86U doesn’t have 6ghz band, only 2.4 and 5 so pretty much same as my rt-ax86s.  I’m considering the BE86U as a replacement for rt-ax86s. Not sure justified to replace rt-ax86u atm.

Thinking of getting ZTE MF833 4G LTE USB dongle for fail over, doesn’t show on compatibility list from what i can tell, anyone used one with be86u and all ok? Then just ned to find a cheap preloaded sim card with x data for say 1 year or similar at a reasonable cost. Not many USB dongles out there now, everything going MiFi it seems.

Given your RT-AX86U EoL window is 2026–2027 you have some time to make that decision and if your happy with what you have then no point changing apart from the sip pass-through issues.

If you go for the RT-BE86U, then you can set up a dedicated 2.4GHz to support an IoT or Guest (depending on the level of segregation you need) wifi network that only uses 2.4GHz.

I had Screen sharing issues between my Laptop and TV using Smart Connect, so I created a dedicated IoT Network and forced our main TV to join it using 2.4GHz and now screen sharing works well.

Thanks.  My RT-AX86U is at parents place and where they live, the power hardly ever goes out so the Sip-passthrough isn’t a major issue as 99% of the time it’s connected with no issues.  I only recall the power going out in recent years when there was a whole network outage across a large part of the country a few years back.  Apart from that, it potentially is only a issue if internet goes down but seeing a router/VoIP hub are online, when it comes back up it likely just reconnects, only had internet go down once with plus net to my knowledge.

As for my home, I have the RT-AX86S and being outside of London and a bit more rural, the power comes in over head and hence any strong winds etc causes the power to them go out, only for literally couple of seconds but its enough to then cause the VoIP hub to not re-connect, hence considering changing it as it is a lower spec model than the 86U i.e. less ram etc so thought might be worth changing it just to see if it makes a difference.  I presume the rt-ax86S is EOL in 2026/2027 also or perhaps already is EOL. I’m guessing router is only support for what 4 or 5 years? I forgotten when I bought it to tbh, will have to look it up but of course I may not of bought it when it was released :)

Do ASUS still continue to produce firmware updates for the 86S/86U when EOL or do they stop providing updates, even if its just security updates as opposed to new features etc? Never had a ASUS router before these 2 so not encountered the EOL scenario yet :)

I quiet like the new interface showing x devices and 2.4, 5ghz etc.  Is that only on Merlin or is that on stock firmware too? the BE86U doesn’t have 6ghz band, only dual band 2.4 and 5gz but should be ok, apart from 2 mobiles and maybe 1 iPad pro, I think that is all that’s WIFI 7 compatible I have and maybe 6ghz compatible.  All my IoT devices i.e. smart thermostat, smart plugs are all 2.4 only and need b/g/n I believe to work and they are fairly crucial to ensure work as I access those remotely when not at home to check things and turn on/off heating etc if outside of standard schedule so need to ensure they all continue to work hence will set up guest with same SSID and pswd to avoid having to re-do all the devices as might take a while to do. The BE96U has tri band I believe but that is way way too price, couldn’t justify the cost just for a home router.

As said I will create separate networks for mine i.e. guest – 2.4, main 2.4 and then main 5g and then connect devices to specific ones to try and reduce the number of log entries of it keep dropping and re-picking up devices it seems

Thanks

ASUS EOL for the UK is 4 Years minimal, after that ASUS can and have provided updates (not fixes) to certain models beyond there EOL date, this happens when say mass security patch to fix critical vulnerability etc. or they are rolling out Mesh fixes which impact older models.

 

e.g.

ASUS RT-AC68U

First Release: Version 3.0.0.4.384.32738 – 2018/08/15

Latest Release: Version 3.0.0.4.386_52062-2025/10/27

.

ASUS DSL-AX82U

.

First Release: Version 3.0.0.4.386_42438 – 2021/04/20

Latest Release: Version 3.0.0.4.388_24919 – 2025/05/02

.

The new interface is rather interesting and is standard on stock firmware also. (I’m still getting used to it myself).

Can you check on RT-BE92U from the web GUI, go to Advanced Settings > LAN > IPTV tab. > Select ISP Profile > Manual Settings VID is VLAN option

btw. screen from attachment below is not from RT-BE92U

My RT-BE92U IPTV setting page has VLAN to WAN option for IPTV services which serves ISP‑specific VLAN tagging for IPTV services.

Note; this is not the same as the VLAN options on say the ASUS RT-BE86U.

 

ASUS VLAN Tab (more comprehensive – not available on RT-BE92U)
