RT-BE92U super slow WIFI

[kazafog]

Hi,

I just bought an Asus RT-BE92U and have found it the biggest heap of rubbish i have ever had anything to do with. Keep in mind I am far from an expert but this is not even up to par with the router i want to replace. It has been on the latest official firmware (3.0.0.6.102_38980) and now it is on the latest merlin firmware (3006.102.6) and the WIFI performance hasn't changed.

So currently i have 3 x Technicolor DJA0231(Telstra gen 2 smart modem) routers joined by Cat6e cables all using the same WIFI SSIDs and I can get up to 380-400Mbps on 5GHz and up to 40Mbps on 2.4Ghz when testing my internet connection (Starlink) using speed test by Ookla.

So initially, I setup the asus and connected it in place of the router that was connected to the starlink. The only settings i have changed on the asus are the IP, the DHCP range to allow for my static IP range and i have separated into the different WIFI bands, I then gave the asus WIFI band different SSIDs from the old WIFI. I have been connecting a laptop and samsung S22 phone, with extremely poor results. With the official firmware I could only get ~100Mbps DL when using the 5GHz while practically sitting on the router and 40Mbps on the 2.4GHz. I have reset via the reset button numerous times which did nothing to help.

Today I learnt about and tried the WPS hard reset which may have had some positive impact, but FAR FROM ENOUGH. After the WPS reset I was able to get ~270Mbps/100Mbps (5/2.4G) once again practically sitting on the router with nothing but the starlink connected to the router. Where as the router I am wanting to replace can get 380Mbps with a steel framed wall between me and the router. If I move roughly the same distance from the asus router the WIFI is unusable, i can connect to it but if i am lucky i might get 3Mbps when using 5GHz and the 2.4GHz connection tries to connect but drops out soon after, which puzzles me. Typically 2.4GHz has always been stable at some distance on every other router i have had and 5Ghz is faster but not quite as stable.

I still have the option to return it but, i am hoping that someone here may be able help restore my faith in Asus and point me in the right direction to fix this thing. At the moment I am starting to think the good reviews all over the net are just well paid sponsors.

Any help will be greatly appreciated. Cheers

You had to check SNB Forums before purchasing it. It is perhaps the model with the most issues reported.

 

[kazafog]

So it seems. I don't understand how it gets so many fantastic reviews, Asus must be paying well.

 

[Tech9]

It has few hardware revisions already for unknown reason, common for ASUS BE-class routers software issues around Trend Micro engine, common for all Wi-Fi 7 products false advertising around supported features, model specific firmware issues and frequently reported connectivity issues on top. It's fantastic indeed. For tri-band ASUS BE-class router go for RT-BE96U, for dual-band RT-BE88U. Both popular around models. They also have most of the above issues, but at least don't cause anger management issues to the user.

I must be in the minority here but this has been one of the best routers that I owned.

I have 2x BE92U's in a Wired Backhaul Ethernet AiMesh system, single SSID, Smart Connect and MLO enabled. AiProtection = OFF, QoS = Disabled. I just connect my devices to it and it does what it's supposed to assigning them to the right band.

Here is a SpeedTest taken on my Google Pixel 10 Pro:

Firmware: 3.0.0.6.102_38980

Me too. It pains me to see folks having issues with the BE92U bc I have it with no speed issues. I do highly recommend folks turn off AiProtection and opt out of policy and disable QoS and then do tests. PS: I live in a highly congested 2.4Ghz wifi environment and put all my IoT on thread so I don't use my 2.4ghz radio. But my 5ghz and 6ghz bands have similar DL speeds as yours.

The HW version on my BE92U is 3.0 if that helps. Production year 2025.
I currently run it with AiProtection on (2 way IPS only). Adaptive QoS on for categories + device priority assignment. Skynet for IP filtering, Scribe for log management. Control D daemon loaded into ASUS-Merlin for DNS filtering. Some other smaller scripts for email notifications on certain events. My ram usage stays below 70%, and at full DL speeds CPU doesn't go above 35%.

For me it's been a great router.

 

[Tech9]

Adaptive QoS on for categories

You can turn it off. Not working due to broken bwdpi engine. Same issue may be affecting Parental Controls. AiProtection is kind of useless with monthly signature updates and parts of it may not work as advertised.

 

[kazafog]

Good to hear some have received decent units.

I will update with my build number when i get a chance. I'm interested in who has what builds.

 

[Tech9]

Check RSSI and link speeds in System Log, Wireless Log. It may give you some clues what is happening.

You know it's good to hear that bc I've been on the fence with QoS. I mainly don't need it bc of speeds but I've had a few instances where my Apple TV streaming gets stalled only to find out my PC is downloading something big (usually battle.net). Also part of my traffic is over VPN and prefer the device assignment (Apple TV highest priority) bc I know VPN traffic can't be "seen" by QoS so I've always felt it was protection from one service or device taking away from my streaming. I haven't had the congestion happen since I turned Adaptive QoS on but like I said I wondered if it was doing anything at all. I've since told battle.net to only download at night so maybe that's the main driver here. Thanks for the feedback.

The HW version on my BE92U is 3.0 if that helps. Production year 2025.

I forgot to check but now that you mentioned it, mine says hardware version 4 / Production year: 2025

Last night i hooked up an old RT-AC68U as a aimesh node with my expensive paperweight and even that did not work as expected. I used a wired connection the rt-be92u connected to the node, but with me sitting beside the node i had the same signal strength as if i did not have the node. Which was poor because i wasn't sitting on the paperweight.

It is the first time i have created an aimesh but it appeared as the node was connected correctly and displayed that one node was attached. Who knows.

I am waiting on asus to respond to basically the same info i gave in this thread. Fingers crossed.

 

[kazafog]

so my paperweight is a HW ver 4.1 year 2025. I'd like to think they should get better the newer the version but it appears as though i am very wrong.

I just checked the WIFI log page as suggested, 2 devices total were connected to WIFI both on 5GHz. The first pic shows the lowest DB level is 3 walls between the lenovo and the router and the speed is that low even after 5 min the ookla speedtest will not finish opening.

The second pic is the medium DB level and is where the lenovo is <8 foot away from the router with a metal wall inbetween the 2. Max speed about 60Mbps as per ookla

The highest DB is with the lenovo next to it. Max speed about 180Mbps.

note: i tested each multiple times as the starlink speed does vary, so the speeds shown were the best. Looking at the RSII Mbps i am guessing that is what it should be be clearly it ain't. ??

I need to get sorted with a decent test without using the internet, so any tips would be great.

 

[Tech9]

Sorry, I can't see much on screenshots like this. I barely see some weak connection to 2x AC clients. Use Windows + Shift + S to select the area of the screen relevant to what you want to show. Example:

sorry mate, i messed up the middle pic.

3 walls away below

[kazafog]

i received an email back from Asus. As far as i am concerned they are trying to waste more of my time, as they didn't even bother reading my description of the issue. But anyway see below for their response it may help someone in future, but it will not worry me cause i am returning the heap of crap.

We understand your frustration with the WiFi performance compared to your previous setup. Please follow the expanded troubleshooting steps below to help improve stability and speed.



Firmware Update

- Download the latest firmware here: [ASUS RT‑BE92U – Support & Knowledge Base](https://www.asus.com/my/networking-...u/helpdesk_knowledge?model2Name=ASUS-RT-BE92U).

- Update via the web interface: open a browser → enter http://router.asus.com → Administration → Firmware Upgrade → upload the file.

- Always restart the router after firmware update.



Factory Reset & Clean Setup

- Perform a hardware reset by holding the reset button for 10 seconds.

- Alternatively, use the WPS reset (hold WPS button while powering on until LED flashes).

- Reconfigure from scratch, avoiding importing old settings from other routers.



Wireless Settings Optimization

- Separate SSIDs for 2.4GHz, 5GHz, and 6GHz bands.

- Set Channel Bandwidth:

- 2.4GHz → 20/40MHz

- 5GHz → 80MHz

- 6GHz → 160MHz (if supported by your devices).

- Manually select a less congested channel using a WiFi analyzer app.

- Disable Smart Connect to prevent automatic band switching.



Advanced Wireless Features

- Enable Explicit Beamforming and MU‑MIMO for better multi‑device performance.

- Disable legacy 802.11b/g support on 2.4GHz to reduce interference.

- Ensure WPA2/WPA3 security is enabled.



Starlink Integration (Important)

- Connect Starlink LAN port to ASUS router WAN port.

- In ASUS router Web GUI → WAN → Internet Connection → set connection type to Automatic IP → Apply.

- In the Starlink app, enable Bypass Mode so the ASUS router handles all routing.

- If bypass mode is enabled, configure static routes in ASUS router:

- Go to LAN → Route → Enable static routes.

- Example:

- Host IP: 192.168.100.1 → ASUS router LAN IP

- Netmask: 255.255.255.255

- Gateway: 0.0.0.0

- Metric: 1

- Interface: WAN

- This ensures proper communication between Starlink and ASUS router. [asus.com](https://www.asus.com/dk/support/faq/1047774/)



DHCP & IP Range

- Ensure DHCP range does not overlap with static IPs.

- Keep router IP simple (e.g., 192.168.50.1).



Placement & Environment

- Place router in an open, elevated area away from thick walls, microwaves, or cordless phones.

- Avoid placing near metal structures.

- For multi‑floor homes, consider adding AiMesh nodes for coverage.



Device Testing

- Test performance with multiple devices (laptop, phone) at varying distances.

- Compare wired vs wireless speeds to confirm if issue is WiFi‑specific.

- Disable VPNs or third‑party firewalls temporarily to rule out software conflicts.



---

If the issue persists after firmware update, reset, and Starlink bypass configuration:

- Please contact your place of purchase to claim warranty.



Update firmware, reset and reconfigure cleanly, optimize wireless settings (channels, bandwidth, beamforming, MU‑MIMO), configure Starlink in bypass mode with static routes, and confirm DHCP/IP ranges. If performance remains poor despite these steps, warranty support through your reseller will be required.

Probably too late now, but since you have a router from the communication company, Telstra, it suggests that you live in Australia.

I noticed that the country setting under the WIFI settings for my RT-BE92U, it defaulted to "Asia", or something like that. I had to change mine to "Australia".
I think it changes channel assignments and power output for some regions. In my case I don't think it made any difference, but it's an easy setting to change.

Looking at your screen shots though, you are getting really weak signals, so I think a lot more is going on than an incorrect regional setting. eg. Someone or something at the factory forgot to attach the cables between the board and the antennas.

It is possible to get lucky with this router. Mine started off good, then got flakey around the end of 2025, after I reduced the power output of my 2.4GHz channel, thinking that it would be a good thing for my small house. It wasn't. But since I have returned it to full power and tweaked some wifi network settings to suit the clients connected to it, it has come good again and has been quite stable for over a month. (Ok, a month isn't really that long a time without a restart, compared to my old RT-AC68U which could achieve over 6 months without a restart.)

I replaced my RT-AC68U with RT-BE92U in Dec 2025 in my condo. It's a small condo, not many clients, but I don't have any connection issues, no rebooting, or anything. The settings I changed was turning off MLO, Assigned IPs to my IoT devices (on 2.4GHz IoT wifi). That's all. Almost all default settings with the latest firmware at Dec 2025. Maybe I'm just lucky but for me it's just a stable good BE router. HW version is 5.1 btw. Just my experience. (in USA, bought it at BEST BUY).

I forgot to check but now that you mentioned it, mine says hardware version 4 / Production year: 2025

Apparently it's on v5.1 now... gosh it got me thinking about my v3.0 model now haha.

Am I correct in reading that your channel utilization on the 5ghz band is 95%? That's very bad. How many neighboring networks do you have? It looks like high congestion. Ideally you'd have utilization level of 40% or lower. I live with 45 - 50% on the 5ghz band. But only high throughput on that band for me is my Apple TV which will be moving to 6ghz band when new version comes out. Desktop and phone are already on 6ghz and I don't even have the 2.4ghz radio turned on.

Change channels until you can find the lowest utilization possible. I saw another post on this thread about country assignment. That could absolutely have something to do with it as well if you are in AU.

Looks like very high congestion.
