Hello forum!
So I just bought a DIR-850L AC1200 router and I'm having some issues with the download speed through the router.
I have a 100Mbps PPPoE connection and I'm testing on a desktop PC with Windows 7 Home (wired connection using the cable provided with the router) and an Xperia Z3 Compact (AC compatible).
After more than 10 tests using the same server on speedtest, my strange results are as follows:
- direct connection to PC (no router): dl: 92Mbps / up: 94Mbps
- wired connection to PC through router: dl: 65Mbps / up: 92Mbps
- WiFi connection to smartphone (one room away): dl: 63Mbps / up: 85Mbps
So first of all, the upload speed seems unaffected, but the download speed is 30% slower through the router and also the wired download speed is almost the same as the WiFi download speed through a wall!!!

Given the fact that both wired and wireless download speeds seem affected, I'm ruling out a bad cable (from router to PC) and bad configuration and/or drivers.
I have run these tests with the default firmware the router came with, then I upgraded to 2.03 from the router interface and now I'm on version 2.03.B1 downloaded from the website. I have restarted and reset to factory settings several times before and after flashing a new version but the results are exactly the same.
I have also read around 20 topics related to wired or download issues for D-Link routers and have I tried using the same suggestions given on those topics.
- DNS relay is on
- I've tried enabling and disabling Multicast - no change
- I have tried disabling all Firewall options - no change
- I have not fond WISH and WPS settings in the new router interface
- I have tried WAN port setting at 1000 and on Auto - no change
- I have tried manually adding DNS server and keeping everything on Auto - no change
Any suggestion would be greatly appreciated.
Thank you in advance!
