[Kendo]

Thanks for the info.

 

[brummygit]

First impressions on my mesh nodes is positive - I had 2.4Ghz devices unhappy on the previous version, but everything seems to have connected currently.

 

[dsring]

The built-in speed test seems to max out at 600 Mbps with this firmware.

The built-in speed test seems to max out at 600 Mbps with this firmware.

Working OK for me.

 

[Damit1]

I have a weird speed-limitation of about 600Mbps with that FW, checked with my fiber company and no changes from their side.

Anyone seen such thing yet?
On previous FW not occurred to me.

 

[govorlivko]

Is that on WiFi or Ethernet?

 

[Damit1]

Is that on WiFi or Ethernet?

WIFI.
Same devices worked without any issue earlier.

I'm getting about 300Mbs slower wired speeds with the latest firmware update. Also using WAN aggregation.

1313.64 down on 4/26/21 at 1:14 PM and today getting 1028.70 down at 11:46 AM.

Getting same here in WIFI issues like you get on Wire
I believe a change they done in the WAN make this happen

 

[tallytr]

Checked Ethernet speed with Chrome Speedtest and looks OK in my case, no issues with that latest firmware for me...
After the upgrade got the message to manually reboot (power cycle) the router…

 

[kibosh]

And debugging was finally turned off!

 

[slyderz]

Has anyone been getting this in the syslog? It seems to be related to adaptive qos. I don't get this in the log when adaptive qos is off.

[sturmstar]

Yes - I also get these log entries but it seems there is no impact ... - I've already sent them to Asus...

 

[bbunge]

Another "minor" fix is that you can now change the icon for clients in Guest 1 WIFI. Custom icons also work.

 

[rudoyeugene]

I'm getting about 300Mbs slower wired speeds with the latest firmware update. Also using WAN aggregation.

1313.64 down on 4/26/21 at 1:14 PM and today getting 1028.70 down at 11:46 AM.

Same here, lowered to ~700mbits while previously had ~950 with ISP's 1gbit plan

 

[1ceLaz0r]

Compare speed tests with ookla website speed test and see if there is a difference

 

[Volt]

Has anyone been getting this in the syslog? It seems to be related to adaptive qos. I don't get this in the log when adaptive qos is off.

Do you have a USB drive attached and DLNA server enabled?

 

[rudoyeugene]

Same here, lowered to ~700mbits while previously had ~950 with ISP's 1gbit plan

Well, rolled back to Merlin 386.2_4, now speeds back to normal: ~940/~940.

 

[ScottJD]

Firmware 3.0.0.4.386_42840 cut my WiFi speed in half on 5Ghz and the speed test in the firmware stopped working.
I am running the RT-AX86U
I tried turning off QoS, did a hard reset with holding down the WPS button and it did not fix it.
So I went back to firmware 3.0.0.4.386_42095 and now I have full speed back with speed test working.
Seems something is wrong with this firmware.
