Wired Speed cut in half

Hi. I've noticed that my router cut wired speed to half when I check it using speedtest.net. If I connect my PC directly to the modem(the same cable I use to the router) I'm getting:

 
20MB Download Mbps  / 5MB Upload Mbps (this is correct)
 
But If I use the Modem->Router->PC I'm getting just half of that.
 
Things I've tried:
  • Factory reset
  • QoS is disabled
  • Traffic metter is disabled

Any help would be useful. Thanks!

Re: Wired Speed cut in half

1. What is the firmware on the R6400? 

2. modem and firmware?

3. Are you testing over wireless or hardwired? (I know you have to be hardwired to test the modem but I'm just making sure)

4. Are all devices getting this speed? Those devices?

 

Current Setup: CM2000-> SXK30-> GS716v2-> RAXE500->

Hi!

Wasn't smart enough to think about trying with another devices. I got 20MB over wifi with my phones(s7 and s8+) so I reliazed that it was my laptop.

 

 

It seems that some DELL inspiron have issues with some app calle smartByte.

Installed latest version and it's giving me 20MB Smiley Happy 

 

Thanks!
