Without a big analysis... I can see...
The WAN is downloading at about (Rx) 12 Mbps, and the Bridge Local & Eth2 master are sending ~ 12 Mbps.
This is the "same" for for download in the computer. = 1.9MBps
Now, a stupid question....
What is your IP configuration for the PC?
First, why don´t replace the simple queue with a queue for 192.168.1.0/24 and check it first....
PC IP - at router STATIC and PC end Auto.
Try to do Simple Queue for:
192.168.1.0 - nothing
192.168.1.0/24 - nothing
192.168.1.1 - nothing
And here is the same story again - INTERFACE LIST Shows WAN RX - TX speed to bridge local 20Mbps
Which is what I got downloading at Static PC at 2Mb/s.
But when I do Simple Queue to see or control actual speed for specific PC or IP - instead of 2Mb/s it shoes only 712 Kbps
There must be something wrong.
Can someone please confirm if that's working!?
IMPORTANT - I'm checking speed with P2P Torrent downloading and just Simple Queue without any limits - just to see actual speed per IP!
