Asus AEX16000E how to see CRC errors? WIFI and ETH?

[x7007]

Where in the menus I can see how the WIIF works and if it has errors to see what makes it better or what the issue and also for ETH to know if the cable causing issues. Tplink routers shows that

Is -93 dBm and Higher is better ? -94 dBm or lower -92 dBm? How can I make it better?

Is this good on the WIFI network ?


Is this good also? -26 dBm is better than -25 dBm or -27 dBm? How can I make it better? no matter what I do it stays the same
Sometimes this specific device get stuck on 1 / 5 Mbps for some reason and doesn't change anymore. it takes a long time for it to happen so I can't test it with each setting. It's a WIFI LED camera that capture the TV screen and shows colors behind Ambision Pro. I always have issues with this device. when first it's connected to the network it shows 2ms-5ms and then after 5-6 of that it suddenly going randomly 50-350 and it always has timeout totally random. and sometimes it can be 2ms for a whole day. I can't understand what actually make this happen, it's power cable? when I touch it's power cable it can time out somehow, but I tried like 4 power adapters so I can't understand how all of them will cause issues.

Could it be the antenna's direction that fixes this issue?
This kinda what happens it can sometimes be a lot worse

This is kinda when it's fine not perfect

There is no ASUS AEX16000E model. There is GT-AXE16000.

Lower dBm numbers are stronger signal, higher dBm number for noise floor are better, lower channel utilization is better, lower latency on any interface is better, 1-6Mbps link to wireless client with good signal usually indicated power saving features in stand-by mode. ASUS routers don't have in GUI retry rate information for wireless interfaces nor Ethernet monitoring other than link speed.

What you can do to improve? Channel change (with lower % utilization), channel bandwidth change (narrower channels have better range, lower retry rates and latency), move clients closer when possible (try to stay -70dBm or lower number). Antennas on most home routers are multiband omnidirectional around 2dBi, moving them around may result in slight improvements only and for specific band.

High interference on 2.4Ghz and there's nothing you can do about this

yes but when it's on power saving and doesn't go out of it, what is the cause?
I moved the antennas and got almost 15 extra, it reach -44 sometimes

It depends what type of client it is. If some IoT it may stay for a long time at minimum link rates with priority on power saving and better range since it doesn't need anything better to do the intended task.

My AP stats in condominium building environment for 2.4/5GHz bands for reference:

There is a family member doing WFH in this place, no much traffic in 24h period. The AP is set on Ch.1 20MHz 2.4GHz band and Ch. 36 40MHz 5GHz band. You can clearly see 2.4GHz band is quite busy in this place with higher retry rates, but still acceptable under 20%. Throughput is ~40Mbps for 2.4GHz band and ~400Mbps for 5GHz band. The ISP line is 300/30 (in case you wonder why I don't push for 80/160MHz wide channel).
