D-Link DWL-G800AP Wireless Range Extender, 802.11g, 54Mbps

I too bought this device hoping to configure it as a bridge, but with the firmware loaded it wouldnt work. After hearing the G810 firmware worked, I tried it out but got a checksum error, but it is possible. You must first load the earliest G800 firmware, reboot, and then load the G810 firmware. Now everything works great.

I've read all the warnings and the angry messages, and decided to go ahead and try it anyway, assuming that I'll figure it out, since I managed to get its predecessor (DWL-800AP+) to work when my network was 802.11b.

It didn't work. I tried all the recommended fixes that I saw here and elsewhere (disable WEP, disable DHCP, disable Super G, choose Channel 1, choose long preambles, etc, etc). Nothing worked. The client would get a great signal from the repeater, but there would be no traffic.

My firmware was the latest: 2.70 on the DI-624 router, and 1.05 on the DWL-G800AP repeater.

Then I tried downgrading the firmware on the router to 2.50, and it worked right away! I am using WEP and DHCP without problems, though Super-G is still disabled (the clients on this network are not Super-G capable anyway).

Bottom line: If you too have this pair (DI-624 Version C3 with 2.50 firmware and DWL-800AP Version A1 with 1.05 firmware) - I believe that you should be able to get it to work.

Once it works - it's worth it! No more dead spots in the house!

PS. I remember that DWL-800AP+ (the 802.11b predecessor) also didn't work with the latest firmware. One would expect newer firmware to improve upon the older one! Not the case with D-Link products!

When it works it does extend the range. However, every time you turn off a wirelessly connected PC and turn it on again, the PC is not assigned an IP number. Unplug this extender, and the PC is assigned an IP number by the router without any problem. A brief power blackout will cut IP numbers to your wirelessly-connected PCs. I purchased this particular D-link range extender because I wanted to ensure that it works well with my DI-624 router. I wasted my money buying this device. It's useless, and it's too light to even serve as a door stop...

As a network engineer, we've setup lots of wireless networks and never has one been so difficult to setup as these DWL-G800AP's and it's partner, the DI-624 rev C.
Their setup manual and live tech support are a joke.
First, make sure you have all correct firmware:
DI-624: Rev2.37 and DWL-G800AP Rev 1.05
(These are the config we used and finally worked)
In the DI-624, Changed the channel to 1, disabled the super G. In the G800AP, run the site survey, and select accordingly, than manually add the GW (default 192.168.0.1). Wallah.. works. I've read that the WEP and security does not work but it doesn't matter since this project is for a hotel.
NOTE: Some changes works immediately where others takes a minute to propagate through the network. If your change does not work after a minute, re-apply that change and try again.
Final word.. don't buy this device if you expect an easy setup.

For those of you who wonders whether this can extender your neighbor's unencrypted network signal, i can tell you the answer is Yes. Just hook up the extender, login to the configuration site(embeded on the device), change it to repeater mode, then choose the network ID that you want to pick up and rebroadcast. It's as simple as that.
