It's hard to explain with text, so I made a YouTube video, hope you guys can learn from it. These XiaoMi routers are OpenWRT based, logically once you get SSH access, you can do whatever you want, if you familiar with OpenWRT. From my personal experience, the AX3600 beats all my routers/APs in hand, including Asus GT-AC5300/AC86U, Huawei AX3/AX3 Pro, Ubiquiti nanoHD/LR, Aruba IAP-225/IAP-315, MikroTik cAP ac/hAP ac2/Audience and many many more in terms of coverage and speed. Also, instead of writing their own firmware, XiaoMi decided to use OpenWRT and put a pretty GUI on top of it, so it's basically OpenWRT router + official Qualcomm driver(NSS enabled), with a decent skin, stability isn't a problem anymore, and due to official driver, performance is great too, it can also do QoS with full speed of my 800/200 Unifi plan. Regarding mesh, I see no lagging during roaming APs, 802.11 k/v and Qualcomm Wifi-Son supported, tested with ping in iPhone, FaceTime and MobileLegend. Love it! AX1800 is about 5% lower than AX3600 in WiFi, and can only do QoS at about 500mbps, without QoS can fully run my 800/200mbps, so my personal recommendation is to get an AX3600 @RM340 from Taobao, and add AX1800 as a mesh AP if you need any extra coverage, both wireless and LAN can do, @about RM170 each from Taobao too.

On webpage, use google chrome translate whole page. On app, can select English in language setting

Logically can be done, but I’m not familiar with OpenWRT, maybe someone who know it well can show us the commands to do so.

"waste of electricity"...... a bit too much to say like this bro, 4x4 not just meant for MU-MIMO, but also coverage. MU-MIMO is always tricky part to test, unless u use some device like SmallNetBuilder do to test, or else u can't really tell it's AP problem or client problem, especially when u only tested by using some models of phone. Btw, with OFDMA, MU-MIMO isn't as important as wifi 5 era anymore.

I bought it from them, RMB539+RMB60 for shipping to Malaysia

True, but luckily we finally managed to get it run on Vlan tagging, the good thing is we only have to do it once and do a backup file, can restore config anytime.

I found this router as picky as AC86U for LAN cable, if your LAN cable is bad, it will jump between 100mbps and 1Gbps, maybe this causes them disconnect.

I got a slim LAN cable, cat 6 32AWG, which I used to power up my Aruba IAP-315 by using PoE+ and 1Gbps connection, never have any problem, but when I connected to this router, it just can't stay at 1Gbps, changed to another normal LAN cable cat 5e 24AWG (not slim type) and the problem's gone, now it's stable for few weeks.

Yes it's very stable, it's original Qualcomm driver based and thanks to Xiaomi didn't do many mod for it.

It’s Qualcomm special technology, to have 2x2 160MHz and 4x4 80MHz running simultaneously, normally if u have 2x2 160MHz client in the network will make ur 4x4 80MHz client stays in 2x2 80MHz, but Qualcomm make it possible to run both at the same time, u may do some research of it.

Saw your post on right.com.cn, but I don't have an account to reply you there, lol

Maybe Maxis changed vlan tagging from 621 to 11? Not sure about it, but glad to hear it finally work for you, just don't forget to do a backup file so that you don't need to do it again if accidentally reset.

Yes, just follow the guide then u can directly connect to BTU

I afraid this is an NAS job to do, previous gen XiaoMi routers has a lot of fancy features including this, they were too greedy to try to bring as many features as they can in order to have more selling point, but in the end non of them useful due to instability. This time they decided to cut all fancy things out and focus on routing and wifi only, I think this is the right way because the most important thing for a wireless router is stable, focus on the main thing is always the right choice.

Stable vs features, you choose. Wanna have both? Can, but clearly not @RM350, everything has a cost.

So far no SSH hack for this model yet

Actually I got the method for permanent ssh access even with latest .67 firmware, will update here soon.

As for PiHole, yes I did edited the DNS server to my PiHole via winscp, now all my client will receive IP and gateway IP from AX3600 and DNS server from PiHole. Will update here soon also, I need to do some screenshots.

Do not point WAN DNS to PiHole, it will ruin everything. Proper way to do it is use winscp, go to /etc/config/dhcp, add list 'dhcp_option' '6,192.168.0.6'
(my PiHole is 192.168.0.6, if u want more DNS server u may do it like '6,192.168.0.6,8.8.8.8' ), by doing this u will get IP form DHCP and DNS server will be PiHole IP

AX6 doesn't have ssh access yet, not sure if they able to crack it, go for AX3600 if you need VLAN tagging

Use DHCP 1st, change it afterward

Actually u can use channel 52~64 by setting it to auto and manually change it via winscp

Ya, so make all the mods before upgrade, and it will stay remain after upgrade. Do a backup before upgrade to save your time, just in case
