DSL half speed through RB133, full speed direct to notebook

RouterOS Beginner Basics
1

Hello all. This is my first post, so using this basics forum. And thank you in advance!

I have used a Mikrotik network for a few years that consists of bridged AP/WDS CPE’s. This is per the WIKI for MESH. I have 6 clients that are non line of sight. Most cannot get a signal from the dsl AP. So one client is 4 hops from the dsl site. This has worked good so far. I did have a Buffalo router between the dsl modem and the RB133 AP.

Now I have enabled PPPoE, on the RB133 at the dsl site, and NAT to the bridge with the wlan and 2 of Ethernets as bridge ports. The PPPoe is on an Ethernet port not associated with the bridge. I have DHCP server enabled on the bridge.

The dsl service is 3Mb. When using a PPPoE client on a notebook W2K, I see 3Mb down using NetPerSec local network monitoring utility. However, and here is my issue, when I connect the notebook to one of the bridged Ethernet ports on the RB133 I can get Interent access, but downloads are at 1.5Mb. Why the halving of the speed?

are pings OK?

Thanks again for any help.

I will copy from telnet the settings:

I should post that OS is 2.9.38

If any more info is needed to debug this setup please ask.

ahmedsaffar76,

I am not versed well enough to know other ways to use NAT. So I used the application example from:

http://www.mikrotik.com/testdocs/ros/2.9/ip/nat.php

/ip firewall nat add chain=srcnat action=masquerade out-interface=Public

I input with winbox, and increased the limits in hopes that would effect the throughput, but it didn’t.

In what way are thinking I should use it?

Thanks for your interest.

Can anyone suggest where I might look for the slowdown? In the netpersec utility’s speed graph the download speed flat-tops at 1.5Mb/s, but if I have the notebook PC’s ethernet directly connected to the dsl modem I see the graph flat-top at 3Mb/s. I don’t want to add the Buffalo router back in there to do what the RB133 should be able to do, do I?

Any ideas?
