Hey, ill updated my internet connection today and I get some huge speed problems while using the Dir 655 Rev b1 (Firmware 2.09)
QOS is off.
SPI is off.
WAN-Port @ 1000mbit

I only use wired connections and here are my results:

with DLINK DIR 655:


with direct Connection:


So i got the questions is this router able to handle that speed? If yes what could i try to fix that problem? =)

Link>Welcome!

• What region are you located?
• Are you wired or wireless connected to the router?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?

Set IPv6 to Local Link only.

Older router don't have any HW NAT or Cut Thru technology so you might be hitting it's limits. 
To check this, set the 655 up as a LAN to LAN AP using this method:
Turning a router into an AP.
The run a wired speed test while connected wired thru the 655...

hey so lets do this step by step =)

- Im located in germany
- the connection is wired only

ISP:
- its a cable connection
- Modem and model this could be hard it seems like my provirder "Unitymedia" has its own model

IPv6 is already set to "only local connections"

If i set the 655 to an AP the connection looks fine:


So it looks like the WAN to LAN forwarding limits the speed :/

probably hitting HW/CPU limitation of the 655. I have 200Mb/10Mb here and I think last time I checked my 655 it was hitting this or just below it. I was working about two years ago when I had 100/3.

Your ISP modem is a gateway router so this could have some impact however since you tested the 655 in AP mode and bypass the WAN on it, I presume this is just a limitation of the HW/FW on the WAN side.

You could try v2.11 or 2.12 and see if they improve anything. However I presume you may not see any improvements.

I would use the 655 as a wired LAN to LAN AP from now on though.
