Who still uses D-link 850L for turbo 800Mbps?
I think mine is bottle-necking and can only get max 300Mbps when direct download. Using cable of course.

Latest firmware 2.10TM.
Wifi, firewall, qos, and ipv6 are all turned off.
Direct download tested using IDM fetching from centos mirror, microsoft iso, and google drive.

The weird thing is, running speedtest is consistent at 840-850Mbps.
Torrent speed is also good at 600-700Mbps.

I tried plugging laptop directly to the ONU hg8240w and connect using windows pppoe. Yeah no problem getting full speed for direct download.
So definitely something is wrong with the 850L.

I'm confused why speedtest and torrents are fine, but normal http download was bottle-necked

Have tried 8,16, and 32 connections. No difference.
Even downloading with multiple server is the same:




Single connection to OVH:



I don't have extra router to test. Maybe its time to get a new one

See, yours doesn't even need to use IDM to get higher speed

After some googling and reading about 850L, the only reference I found similar to issue like this is from a review:

Don't know if this is related to my issue. Also don't know if this happens to all 850L.
I guess it wasn't a problem for 100Mbps. But for speed more than 300Mbps its a.. trash can

STEP 1: Connect to port 1 on ONU
STEP 2: Go to network connections -> Configure network adapter -> Set VLAN ID (500 for unifi)
STEP 3: Go to network and sharing -> Create new connection -> Choose broadband/pppoe -> Enter id/pass
STEP 4: Profit!
