RB3011UiAS-RM - Gigabit Lan strange

Mon Mar 18, 2024 2:15 pm

Hi all,
I have a RB3011UiAS-RM router (OS 7.14.1) and I am experiencing a surreal situation.
On the local network I have a computer (I9 14gen with a 2.5gb network card) connected to a TPLINK gigabit switch (T2600G-18TS). In the Windows 2022 connection status it appears "connected at 1gb" and when performing a speed test through a LOCAL OpenSpeed Test server the result is this: (LAN speed practically 1gb)

Image

However, if you connect the PC cable directly to the router's ethernet port (in my case I used Ether6) the Speed Test result is well below 1gb, as shown below. Both in Windows and in the Ether6 connection status they appear "connected to 1 gb"

Image

My Ether6 port belongs to a local Bridge.

On
/interface ethernet print detail
, the result of Ether6 is:
 5 RS name="ether6" default-name="ether6" mtu=1500 l2mtu=1598 mac-address=64:D1:54:85:03:70 
      orig-mac-address=64:D1:54:85:03:70 arp=enabled arp-timeout=auto loop-protect=default 
      loop-protect-status=off loop-protect-send-interval=5s loop-protect-disable-time=5m 
      auto-negotiation=yes 
      advertise=10M-baseT-half,10M-baseT-full,100M-baseT-half,100M-baseT-full,1G-baseT-half,
          1G-baseT-full 
      tx-flow-control=off rx-flow-control=off bandwidth=unlimited/unlimited switch=switch2
In summary: when I connect from a PC to a Switch that is connected to Ether6, the LAN speed reaches close to 1gb, but when I connect the same PC directly to the same port the speed is close to 100mb!

Is there a possible reason or configuration so that, if connected directly to the port, the speed reaches 1GB?

Thanks in advanced.

Hi, I've already done research on the forum, Stackoverflow and all over Google and I didn't find any similar situation.
Thanks

@Maggiore81 IMHO, that's not the case, with switch between router and client speed is OK

@pocci Have you tried to set 1Gbps for ether6 manually? Server has 2.5Gbit interface, it could be a problem for Mikrotik

Hello
The switching part is not an issue since it is a SWITCH.
Routing through the 3011, with v7 is an issue if you have a bridge.
