Hi,
I have a DIR-855 which is connected to a DSL-526B ADSL modem. The modem is configured for bridge mode. I am on an ADSL 1 connection with a total cable distance of 246m. Speed test shows a download speed of 19228 Kbps.
I use free download manager to schedule, manage and accelerate downloads.
My ISP has an off peak of 2am - 8am.
When downloading between these times I get terrible download speed varying wildly between 0bps and 135kbps, occasionally spiking over 135k for a second or two.
My dir-655 has litterally thousands of this message in the log...
[INFO] Sat Apr 09 07:57:53 2011 Blocked outgoing TCP packet from 192.168.1.1:1581
to 69.16.169.20:80 with unexpected acknowledgement 1141416955 (expected 1141438556 to 1141521500)
What do these messages mean? Are they telling me there is a problem with my configuration or hardware?

Yo sure you have a 855 or a 655? If you have a 855, please post this message in the 855 forum. Thanks

Damn it!! Silly slip up.
DIR-655, not 855.

Is QoS enabled?
DNS relay enabled?
Primary and 2ndary DNS IP addresses filled in under Setup/Internet/Manual?
Advanced DNS Services disabled?
Any 3rd party firewall SW installed on the connecting device?
-
Is QoS enabled?
Yes. Auto-detect connection type. 923kb Uplink speed, no QoS rules defined.
DNS relay enabled?
Yes.
Primary and 2ndary DNS IP addresses filled in under Setup/Internet/Manual?
Yes, these point to OpenDNS.
Advanced DNS Services disabled?
No. IIRC a previous post of mine last year had a response of turning off Advanced DNS services, though I don't recall the exact reason.
Any 3rd party firewall SW installed on the connecting device?
The only softwares are OpenDNS updater, Java Updater and MalwareBytes Realtime monitoring. However, I have tried disabling MalwareBytes and it did not make any difference.
Also, when I do a speed test I'm getting 19226 Mbps. But downloading anything rfrom anywhere else I'm getting really bad speed. Sits on 0bps for minutes at a time.

Try disabling QoS and set DNS to ISP DNS addresses to test temporarily.

Hi Yanta,
I am looking at the Outgoing IP Address in the log you posted.
I would say to do a Factory Reset on the D-Link Router, in place.
Use your Wired Computer to manually reenter all settings, but don't change the IP Address of the Router itself.
D-Link looks at the IP Address of the Router to automatically configure the Date and Time settings in the Router. It looks for 192.168.0.1.

Ok, have done that. Didn't help.
I disabled the OpenDNS updater. No change. Then tried a different downlad manager. No change.
Tried the who thng on a different computer, running windows 7. The download speeds were considerably better, even with QoS on and using the OpenDNS servers.
The only things left are Coldfusion services, Firebird Services and the OS itself.
But if its fine on one computer, and not on the XP machine, is it safe to say that this is not a router issue?

I'm not sure what you are trying to achieve here. I would prefer to keep my network as 192.168.1. There are 15 devices here including printers, PCs laptops and PS3's
Are you saying that th router cannot maintain the right date and time unless it has a 192.168.0 network?
-
the LAN IP address of the Router can be anything, doesn't exactly have to be a 192.168 address, can start with a 1 and up to 192. I've seen single digits, like on mine, some people use 10. Some people use 172. The Lan IP addresses on a home network are not bound to certain addresses like the WAN side. It's just what is recommended and used for general home use.
If you looking to configure the date and time, why not set a manual time server like: time.nist.gov.
Basically, you need to start over. Turn off all devices. Make sure the router and modem are connecting well. Test with one wired PC. Leave off all the others.
Setup static IP address on the router for the one PC. Don't get static IPs on the devices.
Turn off all QoS.
Use ISP DNS to test first.
Do some speed tests with and with out the router.
Once you establish that you get good connection and speeds with one PC, turn the next device.
Graduate this until you can get all going and working well.
Save off the configuration to file. Build your self a working configuration file.
Then go back and start tweeking and playing with openDNS and other settings.

Hi Yanta,
Why change the Router's IP Address, initially from 192.168.0.1 to 192.168.1.1, in the first place?
I am saying that the D-Link Router can't maintain a correct Date and Time from the D-Link Time Servers, if you continue to use 192.168.1.1. The D-Link Time Servers are looking for 192.168.0.1.
You can set the time manually from the computer, but it can't be set automatically, using an IP Address of 192.168.1.1.
Call D-Link Support and ask them for verification.

You can make the internal IP address whatever you want. I run 192.168.10.X scheme, have for almost 4 years now. I used the DLink NTP servers and they won't be looking for the internal address when responding, they will respond to the public IP address just like all Internet communications does.

Hi davevt31,
Out of curiousity, why did you change from the default IP Address for the Router, to the one you are running now? I have always gone with the Default IP Address, since I saw no reason to change it. I use Static IP Addresses assigned by the Router itself, instead of setting up of Static IP Address on the computers themselves. The Devices get a Static IP Address from the Router. And if required by the Device to be programmed with it, I use that IP Address, instead of using the Static IP Address of the Device.

My original router's (Motorola) default was the 192.168.10.x scheme. I have a networked printer that had a static of 192.168.10.10, so instead of going around and redoing all the PC's printer settings I just changed the 655 to a 10.x scheme. I use reserved DHCP for the printer, a Wii and my desktop.I have two other systems that I don't reserve. I also changed the addressing scheme so it only goes from 192.168.10.2 - 11, with the 9,10,and 11 set as reserved.
The internal scheme is just that internal, technically you can run any IP address scheme you want.

Sorry. I dont understand why we are talking about date and time. There is nothing wrong with my date and time. The original post was about terrible download speeds.

Right. Gotcha.
I changed from 192.168.0 to 192.168.1 because initially I was using Netgear or some other brand that defaulted to 192.168.1.1. That was about 10 years ago. Since then, all of my network devices are configured for 192.168.1, including printers and so on. I have always used static IP addresses as this allows me to disable the DHCP service in Windows, though since I've installed windows 7 I haven't really been bothered with the DHCP service.
I've probably built 50 or so networks for family and friends over the last decade and I've always used 192.168.1 since that was the default of the routers I supplied people.
So I guess it's a deeply imbedded habit.
Though, as I said earlier, there are not issues with the date and time
-
Anyway, I think it is time to close this thread.
The problem only exists on the XP machine. All the windows 7 machines are getting between 8000Mbps and 19500Mbps, depending on network load and time of day.
I could not find a realiable central client/server style download manager anyway, which is why I was doing the downloads from the XP machine.
If I can ever find a download manager that allows me to centralise the downloading of files, then I'll build windows 7 machine that turns on at 2am and shuts down when all downloads are completed.
Meanwhile, if the symptoms re different for different computers, then I suspect there's probably nothing wrong with the router or its configuration.
thanks for your help, everyone.
cheers

Hi Tanya,

I read into the messages about Date and Time, sorry.
However, you can look for Horrendous download speeds between Off Business Peak of 2 AM and 8 AM, because the other ISProvider Customers are probably doing exactly the same thing as you are, though from other sites, not necessary the same sites as you.
Besides looking at the computer, tried looking at the Ethernet Adapter and its drivers.
Also you are creating more work for yourself then necessary by setting the Internal IP Address for the computer at the computer, instead of at the Router. It is much easier at the Router than at the computer.
I always look for the easy way out. It is faster.

I posted a possible fix for this (no guarantee) in a different thread, so I'll post it here too.
-----------------------------------------------------------------------------------------------------
I think I know exactly what your problem is. I had the same "slow download" issue. Apparently the DIR-655 router has a problem when the settings on the computer for "Speed and Duplex" are set to "Auto Negotiations" (the router automatically sets the computer to 10 Mbps Full Duplex, not sure why....) and it has a problem with the "100 Mbps Full Duplex" setting on the computer as well (Download speed caps at 1.60 Mbps with this setting). My network card for my computer (Intel® 82562V-2 10/100 Network Connection) only supports up to "100 Mbps Full Duplex". If you have a network card that supports only up to "100 Mbps Full Duplex" and you are still having these issues, I recommend going on your computer and changing it to "100 Mbps Half Duplex". If you have a Gigabit network card and are experiencing these issues, try setting it to "1000 Mbps Half Duplex". For some reason, when I changed it to half duplex, it fixed the download speed issue completely! It seems using the full duplex has some issues with the router and hopefully is fixed in a future firmware update.
To change the "Speed and Duplex" settings, follow the instructions below:
This was done on Windows 7, but I'm sure it's relatively the same with other versions of Windows.
1. On your computer/laptop, go to "Open Network and Sharing Center" and click on "Local Area Connection" under active networks.
2. Next, you will need to click on "Properties" and then click on "Configure" towards the upper right of the "Properties" window.
3. After clicking "Configure" a new window will pop up, click on the "Link Speed" tab and there you will be able to set your speed and duplex settings.
I hope this fixes your download speed problem like it did for me.
