Hey folks !
Three months ago, I purchased an awesome asus RTAC86U in replacement of my old wifi router a/b/g who served for almost 10 years. The change in performances, ranging and stability was astonishing.
Yesterday, I wanted to do an in-depth configuration of this router. I did read a lot of documentation ranging from "best wifi channel practice" to "which tools are useful for a wireless network audit".
Ok, before starting my questions, I'll have to list the setup I have :
- Router is on the 3nd floor of my house
- Router is CHINA region enabled (although I live in Europe). Stock firmware, no merlin.
- Dual network enabled, 2,4ghz and 5ghz, different SSID
- 2,4ghz is 20mhz bandwith on channel 6, 5ghz is 80mhz bandwith on channel 149/155(ac)
- Computer is a laptop, wireless is managed by Intel AC9560 card
- I'm using inSSIDer office for wireless audit
Questions :
Let's start with the 2,4ghz channel first : ASUS advertises the max bandwith on 2,4ghz being up to 750mbps in 3x3 configuration, with nitroQAM enabled.
- inSSIDer says my max bandwith is 72.2mbps in 20mhz (w/ airtime fairness+multi-mimo disabled), as shown in the screenshot.
- When I change the band from 20mhz to 40mhz I reach a max of 150mbps with airtime fairness and multi-mimo disabled on asus router.
- I reach a max of 450mbps with both options enabled.
Are those results normal ? Did I miss anything ? How do I reach this 750mbps as advertised for the Asus ?
When I swap from 20mhz to 40mhz band, the 123456-2G overlaps with the 3 other wifi networks I own : inSSIDer says I then use channel 6 and 10 on 40mhz band. (extension channel is set on "above" on router)
Is this good ? Should I stick with 20mhz band to prevent overlapping ? Or go with the 40mhz ? Does it affect performance of the 3 other wifi networks ?
Now for the 5ghz Bandwith :
- inSSIDer says I'm reaching a max bandwith of 1773 mbps on 5Ghz, which puzzles me : Asus says on his website this bandwith is reachable with 4x4 networks cards, and up to 2167 with 4x4 1024QAM enabled.
How is this possible ? My network card on laptop (intel AC9560) is supposed to be 2x2, so it should not reach 1733mbps ? If I reach 1733mbps on 5ghz, why can't I reach at least 600mbps on 2,4ghz ? How do I reach 750 and 2167 mbps ?
Many thanks to the people who could enlighten me, help me in the process of tweaking this awesome router or answering my (many) questions !
