login to your router menu , go under WIRELESS tab > PROFESSIONAL menu , if 5GHz radio is on or off ( just double check )

could be hardware issue if you have done a factory reset ....
send RMA asap if it is hardware issue

Which seller you get it from? Send it back for RMA.

i bought by a seller from lazada. he agree to replace a new one for me. i return it back, now waiting for the new one arrive...

Hi guys, I am glad i found this thread. I am on ASUS RT-AC55UHP at the moment. I have been turbo-ed to 500mbps but I am only getting 280mbps at most with LAN (and yeap all cables that I'm using are CAT5e or 6). On 5G, I am only getting 200 mbps at most, usually 180mbps.

I called up TM, they came with their dlink ac1200 router, boom 500mbps on mobile! 522mbps on LAN. It blew my mind.

So yeah I was dumbfounded. What possibly went wrong? I checked my router config, nothing unusual.

Somebody please save my ass lol

Please update your firmware to the latest one from here/

You need beta firmware. It is firmware issue. Update your firmware to the one blacktubi suggested.

thanks for the link. apparently the latest firmware version is not working. I tried updating the firmware using the latest file but it kept showing error error error so i tried the october version, it did work...turn off/on router and ran unifi speediest again, speed is still the same.

please advice

Hi guys my first time setup a ac86u bought from China. I have this problem, it didn't show that option to choose unifi home or ppope. I have key in the ISP got it from unifi. Am I doing it wrong?

Go to LAN, then IPTV, from there can see ISP profile?

Yes you are doing it wrong. See jusbella reply.

Wow Thanks so much hahaha, u are really life saver, been stuck for hours. Didn't knew under IPTV setting

To be fair, it is not easy to find. You can actually Google for the manual next time. The reason why it needs to be done is because Unifi uses VlAN tagging, so you will need to select Unifi mode, or manually tag the VLAN yourself.

Enjoy your internet

yes bro i did that, but the latest firmware gave me error so i tried the october version, updated successfully but speed still remains the same

Try with another router, not Asus and see if that makes a difference.

Well TM came yesterday with their own DLink ac1200 router, got 522mbps on LAN and 500mbps on WiFi .

Yes probably your router issue then. You need to wait for Asus to issue a firmware that can handle the speed. Otherwis3, change routers.

u failed to update to the beta firmware, try again...

w/o it, u may not get improvement

i am using rtac1300uhp which is same class at ac55, ac58.

updated similar beta firmware, now i get >700mbps.... was getting 5xx only before.

and yes... the unifi guys showed me 820, 830 with their equipment.

hi guys, i got AC86U and unable to connect to UNIFI IPTV.. (already choose UNIFI HOME).. any help? is that caused by this Enable multicast routing (IGMP Proxy) - DISABLE.. ?
