Connect your router to computer with ethernet cable then you can access it with following default link. http://192.168.1.1 or http://192.168.0.1 or http://192.168.15.1 or http://192.168.2.1 If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it. Then it ask for user name and password. Type user as "admin" and password as "admin" or "password" or blank. Then you can see configuration page of router. If you are still not able to access router with above ip then you need to RESET it for that press RESET button for 10 seconds it is in back side of router then all settings defaults..Then you can access it with above method.
But after RESET you need to reconfigure it with below method.
Click on WAN settings set it as your internet service provider settings enable DHCP Then click on wireless and enable it. . Then click on wireless->wireless security->WEP security there is code password note down it or enter new password then save setting s and restart router. then you can connect wireless with new password. Let me know if you need further assistance. Thanks for using FixYa.

Your type of d-link the highest version is 1.20 which can be downloaded from ftp://ftp.dlink.com/Printserver/dp300U/Firmware/dp300u_firmware_120.bin and updated on your d-link administrator page.

Can anyone tell me, what IP Address when reset to default? thx's...

Click on start>run>cmd. Then type in ipconfig /all. That will give you the IP address to your gateway and any other address you need.
Please rate this solution.

I connected my HP5MP to the DP-300U LPT1 port.
I configured my port on the DLink Configuration tab, giving it a name "hp5"
...The default login is at http://192.168.0.10/ user:admin pass:(there is no pass by default)

On my Mac, I go to System Preferences > Print & Fax
Click the + to add a new printer
Select the IP option
Choose the Protocol: Line Printer Daemon - LPD
Type in the Address: 192.168.0.10
Type in the Queue: hp5
Print Using: Generic PostScript Printer or better yet, 'Select a driver to use...'
and find the driver for your HP LaserJet 5MP.
Save it. Works like magic. ;-)

If you change the IP address or password on the DLink, just CYA and write it all down on a sticky note then tape the note under the DLink chassis. There's no reset button on the thing, and if you're o a Mac, you won't necessarily have access to the Windows utility to jack with the DP-300U. So, write it down, kidd-o!

So... you've messed up the IP address on your DP-300U and now you can't even access the web browser configuration page? Yes, it's happened to the best of us. Although I'm sure there are more elegant solutions, one fix is to reset the server to its factory settings and then reconfigure it from scratch. Given that there is no reset button on the DP-300U, resetting can be frustrating, especially if it's asking you for a password that you never created in the first place! Here's what you can do...

1) Install the psadmin software which came with the print server. If you lost the software, you should be able to find it on the web somewhere.
2) Start the software. It should automatically locate your print server.
3) Click on "factory reset". If it demands a password, and you don't know it, try "SYSxxxx" (where xxxx is the last four digits of the MAC address written on the underside of your server)
4) Dust off your Quick Install Guide and go through the unintuitive configuration process. If you no longer have your Quick Install Guide you can find it on D-Link's website.

Good luck!

You may use the PSAdmin software to configure your print server even if you don't know the IP address. The only requirement is that the DP-300U has to be in the same network (subnet) as your PC running PSAdmin. In the PSAdmin, you will then be able to view or change the IP address.

Here is the link to download PSAdmin:

Remember that if you also have forgotten the Admin password, you will have to ship the unit to D-Link in order to have it factory reset.

Problems with your D-Link DP-300U LOST IP If you’re like me, you have a ton of computer **** laying around your house. Today I found an old D-Link DP-300U print server laying around and thought that I could put it to good use. The bad thing about these things is the fact that they do not have a hardware reset button on them, so if you forget the IP or the Password, you’re pretty much hosed… or so I thought. After doing some google searches for how to find a lost IP, I came back empty. The PS Admin program that D-Link publishes for use with this thing couldn’t find it on my network either. After some thinking, I came up with an idea.
If you know anything about networking and how networks work, you should have thought about this too. Get a Wireshark capture running. Unplug the power from the print server and then replug it. It’s going to send out an ARP on the network looking for it’s gateway which should be picked up by Wireshark. It should look like this:
In my case, it came back as 192.168.1.253. After changing the IP on my laptop to fit that subnet, I was able to log into it via it’s web interface (there was no password on it thank God!) and put it back to factory settings. Voila! What once was a brick is now a working print server!

I Copied it!

hook the print server directly to the computer and program it with a static IP address.
than create a new printer port in add printer. Than setup the printer and use the port you just created and it will work fine

Oooh, same with my problem. I have DP-300U, and now that can't use.
How the producer dlink DP-300U, please follow up this problem !!!
