Got a bad news from friend, his China AC86U just died, less than 3 months he using the router, i'm going to help him send back to China since i help him bought from Taobao.

Finally using Airpak, shipping charge is RM150, asked Yunda (China courier company in Malaysia), shipping charge is RM89 but lot of requirements eg cannot shipped power adapter, Airpak has no question asked. I need to deal with Taobao seller for checking of destination address in China and therefore Mandarin is required.

Shipping RM45.  And you need write address in Chinese.

got this router after researching about it to replace tp link archer c7.
had to return the first unit after 5Ghz wifi became unusable after one day.
so far the 2nd unit is fine except for one problem. its hard for the hypptv stb to connect to the service.
it has the error code 108005. switching the stb off and on will get it working if lucky. already set the iptv service to unifi home in the settings using lan4.
if it does connect, hypptv is usable without any errors. just hard to connect once it is switched on from off state.
even archer c7 is better as it is instant connected. regret spending so much to buy this router with this kind of problem. the seller said to reset the router when i mentioned this problem. same problem after resetting.
wondering if anyone have any fix for this problem.

To buy and use the China unit, here are some of the important thing as your checklist:

1. The current latest hardware version is R1.5. This hardware is not regionally locked and therefore you can use for Malaysia WiFi spectrum. If you get other hardware version, maybe it will work or maybe it will not work properly with WiFi devices in Malaysia.

2. For the power adapter, you just need to plug it in a universal converter, or a universal power socket. No need voltage conversion as it can be used for 240V power line.

3. Change your language to English. Download the official latest firmware from Asus support website, and flash it manually.

4. Once you flashed with the latest international firmware, it is recommended to flash with latest Merlin firmware (current version is 384.6). I found Merlin firmware to be stabler and more configurable for Malaysia environment.

5. Go to Wireless > Professional, set the Region from China to "Asia" (not Singapore). This is very important. You will see the available WiFi bands are slightly different among the regions. If your router does not have this option or unable to change it, then it is a locked hardware version.

6. Set WAN internet detection to "PPP echo". Set both MTU and MRU to 1480 (from default 1496). You will face network problem with 1496.

7. Go to LAN > IPTV, set to Unifi-Home for Unifi (set to Maxis for Maxis).

8. Go to Administration > System, set time zone to Kuala Lumpur.

same as mine. i think because the igmp/multicast disable (Due to hardware limitation, IGMP proxy cannot co-exist with IPTV function.), i am using ac58 before this and no problem,...

Here is my setting:

Connection Type: Native
Interface: PPP
DHCP-PD: Enable
Release prefix on exit: Enable

Connect to DNS Server automatically: Disable
IPv6 DNS Server 1: 2606:4700:4700::1111
IPv6 DNS Server 2: 2001:4860:4860::8888
IPv6 DNS Server 3: 2606:4700:4700::1001

Enable Router Advertisement: Enable

I have read about it at web and its a problem to everyone

got such setting in taobao router? o.O
