Title: Slow internet speed (wired) compared to DIR-655 or DSL modem
Post by: lave485 on December 05, 2008, 11:42:29 PM

I recieved a DIR-615 rev B as a replacement to my DIR-615 rev A that broke (within warranty) from D-Link. 
In the meantime, I got a DIR-655 to tide me over. 

I have been trying to set up the DIR-615 rev B that I received but I am having issues with slow internet speed (wired).  I tested it with connecting directly to my DSL modem (AT&T) and the DIR-655 I was using.  Both DSL modem and DIR-655 shows a consistent benchmark of 1300 kbps to 1500 kbps using CNET's bandwidth meter.  With the DIR-615 rev B, it was only showing up with 300 kbps to 600 kbps.  What is possibly causing the slowdown?  I have upgraded the firmware and tested the different settings and even disabling all the firewall settings.  All tests were done using the same network cable... same DSL modem.

Appreciate any feedback.  Is this an issue with DIR-615 rev B?  I did not have any problems with my DIR-615 rev A until it stopped working.

At what firmware level?  The latest (2.25) has a limited QoS engine.  This might cause the slow down problem.

Try lock WAN Port Speed to 100mbps and test it again.

thanks... setting the WAN port speed to 100 Mbps helped.  I get the internet speed as I expected.  I also turned on the QOS engine... although I was the only one on on the router so I didn't think it would have any impact.

Thanks again.
