I'm using Netgear orbi mesh, wondering if this can cover a 4room hdb? Last time my ac68u didn't manage to reach the master bedroom
If you place it middle of house, maybe can. But you could pair it with your ac68u ( if you still have it ) using AiMesh.

With this router..

It seems i can never never achieve a link rate higher that 192mbps

With my old router (rt-ac88u) I can get 866mbps at full signal.

Not to mention, at this link rate (192mbps), its impossible to stream a 4k video (50gb file size).

I could easily stream this when using my ac88u

AX-88u firmware version: 3.0.0.4.384_6210

Ur ax is it disabled? You don’t have the clients you try disable first and try again.

AX has been disabled, HE has been disabled

In any case, I decided to flash the merlin firmware into the AX88u, straight away i can get the desired maximum link rate. What is interesting is that I noticed my huawei P30 was connected at a link rate of 1.5 Gbps (with 160mhz enabled), I did not have a chance to stream a 4K video yet to see how it goes. Streaming videos on my nvidia shield tv was drastically improved. I figured that maybe speedtest might not be the best way to validate the performance of the link rate.

The only issue that i noticed now is that it could not sustained the connectivity, it will disconnect occasionally and reconnect again. Resulting in interrupting the video stream.

Some advice needed.
What's the best setting for this router for 5g? Enable 160mhz band and disable HE from what I see are the key changes? Do you all also enabled DFS?

It seems that this router have a special preference for channel 149 in my case, which result in slow performance...

In the 5Ghz settings, instead of setting the wifi channels as auto, set it as channel 36 hardcoded. YOu will see significant increase.

Reverting back to asus official firmware caused my wan ports to be down once every few days, and i need to reboot. Merlin seems stable but wifi signals tends to drop when there is a huge file transfer.

Honestly,at this point, I would gladly trade my AX88U for a BRT-AC828U. Getting pretty exhausted taming this beast.

Try lower channels for 5ghz
Also lower mhz would be preferred
Say 20/40mhz < can try turning on just 20, but auto is fine for my case. I would highly recommend turning off 160mhz for 5ghz. Avoid dfs channel as well (not stable)

media bridging with AX88u

Anyway not sure if anyone have tried out...

I did a media bridge (replacing my powerline) using my very old RT_AC66u, and did a file transfer of a very large file across.

Performance hovers around 25 to 30MB/s, that's close to 4 to 5 times the performance of my powerline connection.

I am curious if using an AC88u as a mediabridge, would the performance be better.

It would perform better if the link between the 2 is over 5ghz

My current connection is over 5ghz, ac66u is a 3x3 mimo with a consistent link rate above 1000mbps

What I mean to say is over 5ghz, confirm AC88U (4x4) > AC66U (3x3)
But whether the improvement is worth buying the AC88U, I can't say for sure.
