I would like to share some problem and solution I found to all. My model is DIR-878, may apply to its sibling model.

Problem - getting capped at 200mbps instead of 800mbps download speed. Yup, unifi turbo just rolled at my location.

Solution - Under QoS Setting, remove any device linked to the priority table. My speed was capped even when I put my PC in Highest priority, once I remove it from the list, it can download at 800mbps.

Note - all testing is done in gigabit network with CAT7 cable. No hardware limitation here.

Side note - I need to pay unifi personel (will appear in my bill) that come to my home to check this, cause the problem is caused by my side, not unifi. I have them come with their router and tested running at 800mbps.


On the other story, while setting my router, I use the old IE, everything was ok, except VLAN pages failed to load, no error whatsoever, just a blank (the rest of the menu and logo is still there). Then I use chrome, whenever I try to apply setting, it will ask for my router password and restart the whole procedure again.... however the setting wasn't applied. While using chrome, I can see like few hidden setting on the menu, but unable to access it (this wasn't appear at all at IE nor edge). Lastly, everything when smooth with Microsoft Edge... Any idea how is this happening?

If anything like me, may need try othe browser. Try edge, mine has problem like yours in Chrome.

i'm using this model, no problem getting 800mbps. just watch out for QoS engine. just leave it as default. dont touch any of its settings.
Called their customer service, they said can support up to 1000mbps. Future proof abit i guess?

my double storey house cover well. no dead spot compared to my old router

Do anyone having trouble with the new DIR-X5460??

Problem
1. Keep getting randomly disconnected from the internet and it automatically reconnect later on. There 1 time it took 1 minute to reconnect.
2. Within the 1st 24hours of use, my wifi signal totally gone, but when i check the setting, it was enabled. The fix is just restart the router, however this shouldn't happen anyway.
3. Obviously I bought DIR-X5460, why in setting it was named DIR-X1560?

Is this a known issue or should I get a refund?


[UPDATE] It seems that D-Link themselves flash the wrong firmware on my batch. Download the firmware tsd.dlink.com.tw
Then do manual firmware update, now tested for 12 hours without a single disconnection from the internet (compare from before at least once every hour).
Will report back if the internet connection still unstable otherwise can consider already fixed.
