Title: Lan Speed on DIR-655 A5
Post by: Torres on August 03, 2010, 02:40:27 PM

I there!

I'm Portuguese so, excuse if i give errors on my writing.

In this week i buy three DIR-655:

1- DIR 655 A5 1.21EU
2- DIR 655 A5 1.31EU
3- DIR 655 A5 1.21EU

I tested the speed of LAN, my 2 desktop have Gigabyte LAN cards on board.

The 1st DIR 655 i have 850 mbps, good!
The 2nd and 3rd DIR 655 the max speed i get is 550 mbps.

Ths first and second i put back to the shop.
At the moment i only have the 3rd DIR 655 with 1.21EU firmware.

The 550mbps is bad in my opinion, i see tests of other routers and they have speeds between 700-900 mbps.
I only get 550 mbps....

There is any configuration that i have to do in the router? :/

Help me please.

Ps. What is better, 1.21 EU or 1.31EU?
Why when i try to update firmware of the routers that have 1.21EU firmware, the router don't find updates?
The second that i buy have 1.31EU :/

Sending files from one pc to another, both with Gigabit Cards...

I do that alot between two desktops and a laptop (wired gigabit).

I get a 1.0 Gbps connection (from Windows status) for all connections, but throughput, I'm assuming because of the ethernet protocol, is at max on my system, about 450 Mbps.
I can get a sustained 250-350 Mbps.

I watch it with BitMeter II (http://bitmeter-ii.en.softonic.com/).

I hope this helps.

Tks my friend!

I have a max. of 550mbps and i was expecting more :/

I have CAT5e cable, its the minimum for Gigabit Lan.
But anyone now if i install CAT6 cable i will get a little more speed?

I don' think so, I think it is an ethernet protocol thing.

Please note that cables are not all the same.  Some "certified" Cat5e cable do "degrade" to slower speeds.

I agree. Not all cables are the same.
But I have Cat6 all the way on my network.
So upgrading the cables most likely will not make a difference.
