I always set the daily reboot for maximizing stability, so I can leave it at corners and forget about it

Try to change the LAN cable, these Xiaomi routers seem as picky as AC86U, I had an issue like you, in the end I found that it jumped between 100mbps and 1000mbps for cable connection speed causes connection issue, solved by changing to a better cable.

Also, these Xiaomi routers come with a power adaptor which just enough for it to power up, as a power supply we do recommend to have more than 50% power reserve but Xiaomi original power adaptor only has about 20% power reserve, it might cause some instability issue depending on the stability of your house electricity supply. I upgraded AX3600's original 12v/2a to 12v/3a, and use the 12v/2a to power AX1800 which originally came with only 12v/1a. It's not necessary unless you are facing stability issue, I did it just because I have an extra 12v/3a power adaptor.

This is due to MSS clamping, some router will change MSS according to the MTU that you set and some doesn’t, so I will always use default since I never notice any different between 1480 and 1492, no lower ping and no faster speed, an extra 12 of MTU doesn’t make things day and night, so just leave it at 1480 and you are good to go.

Saw this in Low Yat Plaza, RM549....... It might come with international firmware, from what I found in openwrt forums regarding int firmware is it has language option, with lower txpower, and no VLAN tagging option.

Check via SSH command, China AX3600 has 31dBm/29dBm/27dBm for txpower high/mid/low, int firmware might have much lower txpower in order to match worldwide regulations.

1. CPU downgraded, I think this processor can only do 500mbps QoS, AX3600 can even handle 1000mbps QoS.
2. The extra speed required client to support, unless u have the latest Snapdragon 888 phone, or else it’s nothing to u.
3. SSH cracking is unknown, hopefully XiaoMi doesn’t lock SSH access like AX6.

Conclusion, unless u have 2.5G LAN or have latest Snapdragon 888 phone, or else AX3600 is better for u

It should be work if u have the correct VLAN tagging

Since it’s actually openwrt based, you may look for solution in openwrt forums, see what commands can set VLAN for iptv for LAN port 2/3

Change app region to mainland China

Xiaomi just released AX3600 firmware with AP mesh mode supported, just go to official website download the latest firmware and update manually.

Unless u have 4x4 160MHz client (which I can’t seems to find any Wi-Fi adaptors or smartphone/laptop supported in the market), or else u can’t tell any diff between this 2 models for Wi-Fi, but AX6000 has some obvious downside 1. CPU is much weaker, 2. beside of the 2.5G LAN port, the rest of those 3 LAN ports shared 1gbps to CPU which will seriously limit ur speed, unless u only need 1 LAN port only.

For me, AX6000 looks good on paper, but AX3600 is much practical in real life.

It seems can be done by using WinSCP, in network there change IPv6 to “relay”, but I’m not really sure exactly steps for it, u may dig in openwrt forum to see how ppl use IPv6 relay.

AX3600 has (compare to AX6000):
Better CPU
Better 2.4GHz (dedicated chipset)
SSH access (so VLAN tagging is possible)

AX6000 has (compare to AX3600):
Better 5GHz performance (5% faster, more OFDMA client supported)
Better 5GHz radio coverage (in radar pattern, AX3600 is strong at front and rear, but weak at sides, AX6000 fixed it)
2.5GHz WAN/LAN port

AX9000 has (compare to AX6000):
Best CPU among these 3 routers
Best 5GHz chipset for 5G1 (even more OFDMA client supported)
Better 2.4GHz (dedicated chipset)
Slightly smaller 5GHz coverage than AX6000 due to Tri-Band, about the same with AX3600
2.5GHz WAN/LAN port


AX3600 is a better router and AX6000 is a better AP, AX9000 seems strong but it doesn't give you better coverage

Dual-wan is not supported but possible if you has good knowledge OpenWRT, same as IPTV VLAN tagging
