History:
I have the dir-655 V: a2 (love them) bought over 8 of them for friends and family who needed routers 1 time setup never have to touch them again.
I have had mine over 3 years.
I am not sure exactly what the trigger for this was but on 6/2 I could no longer keep a good 802.11n connection on my laptop.
I did thorough troubleshooting regarding the laptop network but to no avail.
So I check the router and notice that none of my n devices are connecting via the n protocol. All are connecting via the g protocol.
Rebooted the router for the first time in ages and it took a while for the auto negotiate for uplink was taking a while and when finished my network speeds went to 2mb Down/50kbps up. My normal Mediacomm cable connection is 12mb/1mb
Bypassing the router I got correct speeds from my ISP.
Reconnected router, back to 2/.05.
Turned off all other network devices (two 802.11n phones, 802.11n laptop, 1 802.11g printer , 802.11g Wii, and 2 of my wired desktops. )
Rebooted again, no change.
Found out the button in the router to check for updated firmware was not giving correct results.
Updated firmware from 1.21 to 1.35NA
Reloaded previous config file, same issue, 2down/.05 up
Reset factory defaults, no change.
I had an issue about a year ago when I setup some port forwarding on the router and with the port forwarding on it was doing the same thing and through very little help from dlink support figure out that by manually setting the wan speed from auto negotiate to 100mb it fixed that issue.
After resetting factory defaults, changed wan port to 100mb , still no change (and of course as everyone knows I rebooted the router after every change since you must >:( )
So while troubleshooting and handling router I noticed it was very hot, even though it’s in a well ventilated area. So I thought maybe I popped a capacitor and it was just dead. No big deal such is life I ordered a new one.
But wait… Coincidences of coincidences I am helping a friend with his network bridge at his office the next day and in his closet is a dir-655 sitting in a closet not being used.
He was having network issues and his ISP came out and said his 655 was the problem, he went and got a new router and problem solved.(he was not told what was wrong and has no clue why it was the router).
So I snag it from him, take it home to mess with and everything looks fine on it so I hook it up to my cable modem and OMG it does the same exact thing.
2mb down/.5 up
Updated firmware because he was also on 1.21 to the 1.35NA
Reset factory defaults. No change
Changed wan port to 100mb, no change
So I am thinking there is too much of a coincidence on this. So I do more digging and not sure where I saw it but someone pointed me to the QOS engine uplink speed.
Unchecked the Automatic uplink speed, set manual uplink to 1024kbps
Changed connection type to cable or other broadband network
Rebooted and wow it works on my friend’s router.
So I go to mine changed it on there and fixed it too.
SO… in short there is a firmware issue or something causing the auto negotiate on the QOS engine uplink speed to not work properly.
Hope it saves someone else some money since I got a new router coming in the mail that I don’t need any more.

It's best to use DHCP (Static) Reserved IP addresses on the router when using QoS or any other feature that you tie a IP address to.

I was not using QoS for anything. It was on the Default Manufacter settings.
-
i understand that. Out of the box, I think QoS engine is running however is not tied to anything specific. TO use QoS effectively, you would assign a reserved IP address to a device on the router then input this into the QoS engine and add ranges and ports. If your not needing QoS then you can turn it off.

Sure that may be so, but my point is "out of the box" with updated firmware and default settings the QoS engine is causing an issue at 2 different networks with 2 different providers which to me sounds like a firmware issue.
Someone who has a dir-655 and is troubleshooting and setting things back to manufacter defaults may run into this issue. Since my discovery I have came across 2 more people with the same issue.
Someone troubleshooting may not know to disable something that is enabled by default to solve a communications issue caused by an automatically detected system.

Good information. Thanks for sharing. Hows it working now for you?

Working perfect on both networks.
Im feeling kinda green saving a 655, found dead in a closet, from being tossed in a landfill by giving it life again. :D

Good to hear man...should work well for ya. Let us know how it goes. ;)

I noticed the same issue. My connection 25Mbit up/down was limited to only 2Mbit up.
What is the use of limiting upload speed on a router that has 4xGb LAN and a Gb WAN connection ???
Is it possible that D-link changes this? Otherwise the QOS function is useless.
-
To make QoS work, you need to set up some devices and rules for it to work correctly. IT's just like Gamefuel on the DGL routers, there enabled out of the box however really need to be set up for proper use. Check out the DGL-4500 forum stickies on how they are used for gaming. They do work.

@FurryNutz
Problem is that I need to enables WAN shaping before I can use QOS. WAN shaping forces me to choose for "Automatic Uplink Speed" or "Manual Uplink Speed". So therefor my upload is limited to only 2Mbit.
WAN Traffic Shaping
- Enable Traffic Shaping :
Automatic Uplink Speed :
Measured Uplink Speed : Not Estimated
Manual Uplink Speed : kbps <<
Connection Type :
Detected Network type : Not detected
QoS Engine Setup
- Enable QoS Engine :
Automatic Classification :
Dynamic Fragmentation :

Have you tired typing in a UP link value in the manual speed box?
You really have a 25Mb Uplink speed?
Does automatic see the uplink speeds correctly or not?
-
After changing to automatic speed up it takes 70 seconds before the webinterface continues. Then the webinterface of the router shows the following:
Message:
Please wait...
The gateway is currently measuring your network connection.
Accessing this web page might have an effect on the measurement.
This page will refresh shortly.
In the webinterface it now shows:
Measured Uplink Speed : 4878 kbps
With speedtest.net it does seem to give a correct value when selecting Automatic Uplink Speed. Maybe I had this issue with one of the previous firmware versions. In 2 days I upgraded from 2.00 to 2.01b5 to 2.01b6 to 2.02b8 so maybe I lost track, sorry.
http://www.speedtest.net/result/1448632558.png (this UP value is not correct, it should be 25Mbit)
-
What happens if you manually type in a value in the manual speed box? Say 101024 or 150512? Will it accept an entry like this?
It's possible that your UP link speed exceeds what these routers can do. This is a first time I've seen UPLink speeds this fast for home users let alone SOHO/Home routers. At most I've seen posted is 10Mb I think. A few 5,6,7Mbs speeds here and there. I'm currently on 2Mb Up and 50Mb Down. It's possible that these routers might not be designed for your speed. You might need a more robust or business class router to handle the speed. I asked my resources about this and will post back with information. Is this package speed for home or business?
Also what ISP modem make and model do you have?
BTW, can I move in with you. hehe. ::) Love to have 25Mb up pipe to share. Wow.

If I try to enter 2049 and click save it will show the following message:
Max transmission rate should be between 20 kbps and 2 Mbps, inclusive.
The village (50.000 people) I live in will have at the end of 2011 fiber in every home so non-business. The maximum speed available now is 200Mbit up/down 8)
A friend of mine also has fiber and has a 100Mbit up/down. He also has this DIR-655 router and was very happy with it. So I assumed it would be enough for a 25Mbit up/down connection. Now it seems my friend has a A5 revision and I got a B1 revision. Too bad this B1 revision firmware seems to have some bugs :(
But using something like torrents is no problem for the router, it easily transfers 2.5 Mb/sec up and down, if not too many connections are used. Above 200 the webinterface of the router will get less responsive.
The modem I have is a genexis: http://www.genexis.eu/products.php?id=ethernet_voip

One thing you can do, you said you have a buddy with the same router and if he's on the same ISP and near by, can you take your router to his place and put it on line and see what happens? Ask him if you can take his router to your place and put it online? Save off the config files for each and test them out on each others routers. This should let you know if there is an issue with your router or not. Would be a good test.
