RB1100 can't use all bandwidth with one connection,Need Help

RouterOS General
1

Hi guys, i need some help!

I have a routerboard RB1100 configured as my main firewall, with the following services:
-Firewall
-NAT
-L2TP
-queue

I have a dedicated internet connection (FO) 20 Mbit on port 10 as my WAN.
i Have a Lan on port 1 (10.0.0.0)

The problem:

On workstation, i can’t use all my bandwidth in one connection, ex: I can’t download a file throw (http, ftp, scp…) using just one connection. It1s not a limitation on the otherside, because i’ve tested a download on another site with the same bandwidth. I have enought free bandwidth but my download stays in 30kbps.

Any ideas?


i’ve made some tests:
-disable all queue(basic one).
-change MTU avoiding package fragmentation.(no success)
-Creating a NAt to single machine.
-disable firewall rules.
-check Bandwidth option on wan and lan interface(unlimited)


Sorry for my bad English and thanks for your attention.

Hi Mario, tks again,
i have these entries on queues type

queue type print
0 name=“default” kind=pfifo pfifo-limit=50

1 name=“ethernet-default” kind=pfifo pfifo-limit=50

2 name=“wireless-default” kind=sfq sfq-perturb=5 sfq-allot=1514

3 name=“synchronous-default” kind=red red-limit=60 red-min-threshold=10
red-max-threshold=50 red-burst=20 red-avg-packet=1000

4 name=“hotspot-default” kind=sfq sfq-perturb=5 sfq-allot=1514

5 name=“default-small” kind=pfifo pfifo-limit=10

i didn’t change this confs!!!

I know it could be a lot of things, i’m trying to discover a path to a solution, this problem could be a limitation on my ISP?
I just changed my RB1100 to a RB450, and the same strange thing happens!!!

I’d like to know if anyone ever heard about my problem!!!

Tks again!
