What our customer's say!

"Hard to install", Although I'm not a computer novice, this unit was hard to install. While the green LAN (Ethernet) light came on when plugged into the router or DSL modem, it didn't work when plugged directly into my PC or laptop. Someone here wrote that in such case you need a "crossover" ethernet cable (or adapter). THANK YOU! I learned that routers have the smarts to figure our what type of unit is plugged in, and automatically assign transmit and receive signals to the proper pins. My PC and laptops didn't do that, and the DP-311U wasn't smart enough either. Hence I needed the cross-over cable (just for the one-time setup). Sad thing, before I figured this out, I spoke with 2 people at D-Link's technical support; we spent easily two hours. But neither one suggested the cross-over cable. They must have had tons of calls like this before. Of course, the manual says mothing about this either. Amazing how they waste time and money.

"Works Great, after you're done setting up it up...", The server works great on my HP 2200. It's fast, reliable and can be easily velcro-ed to the side. Downside, it's got to be the single most difficult piece of hardware I've ever had to setup. NO WIZARD! Anyway, I followed the instructions to the letter and after setting my network IP address back to normal, the box would cease to work. I tried a bunch of things to get it to work, but in the end it was something simple. I'm using a Netgear WGR614v6 which is set to be a DHCP server. The list of available IP addresses missed the default 192.168.0.10 so the computer could not recognize it. I changed the DP-311U's default IP address in the PSadmin program and BAM! Works first try! The morale of the story, if you're running a DHCP server, check the list of IP addresses.

"Didn't work", Wouldn't work with my HP K80. I guess I should have done more research

"Difficult setup, works after it gets going", I could not get the wireless portion to connect for a while. While searching for a solution, this site was at the top of the list so I decided to post my fix here.

It seems that when the 311U is configured using the ancient-looking PS Admin utility, it has a small bug/feature. PS Admin converts the wireless SSID to ALL CAPS where as my wireless network name has mixed case. Talking directly to the 311U, via a web browser, I was able to set the SSID correctly and get m'self up and running.

Hope this helps.

"Configuration is big task", I bought the product 2 weeks before and I have a thought this will work with all printers but not. D Link technical support is very bad I called at least 10 times to find my printer is compatible or not.

User manual is not complete so configuration is very difficult. Changing the IP Address manually and re assigning the new IP Address is very difficult. And it cause problem for other wireless divices (Mouse,Keyboard,Wireless web camera and External wireless hard disk). Because of this product I spend almost 8 hrs to solve other wireless network issues.

If you have enough time then it will entertain you.

Read this reviews before You buy...

"NOT compatible with multifunction printers", After 3 hours of banging my head against a wall I finally called Tech Support. They finally figured out that this is not compatible with multi-function computers. You can learn that on their support website but no-where in the standard documentation that comes with it.

"A Solid Little USB Print Server", I too had a little difficulty getting the right IP address of this device so that I could connect to it via my web browser. That was overcome by reading some reviews and the instructions. Amazing huh? hehe.

After getting this thing working, it has been working great and I feel that there is little that needs to be tweaked/modified to make it work just the way you want. Basically you want to share a printer, and that is exactly what this lets you do. I need to upgrade toe 802.11g now though.

"Solid, but tricky to setup", As several other reviewers have noted, this can be a beast to setup. The difficulty, I found, comes to trying to get the dp-311u to work wirelessly. After 50 minutes of fiddling with it, I started to suspect that it might not be wireless (a mistake several other reviewers shared).
The steps given by s.banks below are better than the lousy manual. But even after following them I had trouble. I eventually found that it was the MAC address security filter on my router that was preventing this thing from working wirelessly. What you have to do is: add the device to the MAC filter list, then disable MAC filtering on the router, unplug the dp-311u, re-enable the MAC filtering, then turn on the 311-u. It then started working wirelessly.
I'm subtracting a star for the majorly painful setup, and another for the very limited printer compatibility list.
Other than that, it seems like a solid product.

"Works well for only under a year w/ a PC", I could not for the life of me get this working for a while, but once I did get to the web-configuration I couldn't get it to work with my existing wireless network. Although this was due to my stupidity, the lack of Macintosh documentation and software made it quite difficult to set up on my mac, and I might have been able to get it working sooner if it had this documentation. Finally, about a year after the year-long warrantee expired, it broke. I called customer service, and, despite what other reviewers have said, they were extremely helpful and tried everything within his power to fix my problem. But, the product was indeed broken and now I can't return it because it's beyond warrantee.

"Great, once you get it working!", My network is two wireless XP laptops and a Linksys 802.11b router so I was a little worried about mixing networking brands - but it worked out fine. Virtually no slowdown compared to having the printer directly connected to the laptop and I print some pretty big files. Setup wasn't too bad (~15-20 min staring at the manual really confused, 5 min reading amazon.com reviews, ~20-30 min installation). Much like what Hafizullah said, it's better to config in steps: configure the printer in the wired configuration and then get it to work wirelessly. Since the manual is mostly useless, here's what I did:

1. Wire it up (connect the print server to the router with an ethernet cable and the printer to the print server by USB).
2. Turn on printer, power on the print server (after startup sequence of ~20 sec, ethernet light should be lit).
3. At this point open up a browser and go to "192.168.0.10" and the print server config utility should start.
4. Click on the "configuration" tab and set: password, connection mode (mine is infrastructure), ESS-ID (your network's name), wireless channel, WEP (# bits and password). It's important to type the WEP key in exactly with no spaces or dashes because the utility won't give any error message if the password is wrong. Click 'save'.
5. Click on the "Network" tab and change the IP address if you want. It has to be within the range of assignable IP addresses for your wireless network (e.g. my router assigns from 192.169.1.1 to 192.169.1.101, so I set the print server to 192.169.1.2). Make sure to set "manually assign" otherwise you won't know what address your printer is on! I think the workgroup has to be set, but I'm not sure (I set it to the name of the wireless network).. Click 'save'.
6. At this point you should be able to print a test page. Click on the "tools" tab and click to print a test page. If it prints, you're in business.
7. Now you can set up the printer drivers. The instructions are actually pretty good for this, so use them here. Once that's done, try printing something that isn't a test page to make sure the printer itself is set up OK.
8. Now to configure the wireless portion. Unplug the ethernet cable, and click the reset button (recessed in the back of the print server). Once it finishes booting, the "wireless" light should be on or blinking. If so then you should be done. Try printing something.. I didn't have everything correctly set up initially, so this step took a few minutes. I think everything necessary to set was covered in #4.

Good Luck!
