Looking for solutions- my DAP-1555 has stopped working in bridge mode.  Here's some background:

About 2-3 months ago, I added a DAP-1555 in bridge mode to provide a wireless connection for several ethernet-only media devices in an unwired part of the house. This set-up, on a 2.4Gz, 802.11N-only, WPA2/AES network from my DIR-655, worked great until two days ago.

I logged onto the DAP-1555 just to check its client table and make sure all the devices were still connecting properly (rather than going into each device and checking individually), and to check whether the firmware was still the latest (it was).  The only setting I changed was removing my admin password. After "Save Settings" and "Reboot Now," the DAP-1555 failed to come back online after the reboot.

I've tried everything I can think of (see below) but the DAP-1555 is now inaccessible/unconfigurable/unusable in Bridge mode.  Access Point mode still seems to work normally, but that's useless for my application.  Here's some more info:

SYMPTOMS (in Bridge mode unless otherwise noted)

• Status lights seem appropriate (steady Power & Bridge LEDs, flashing LAN LED, Status LED flashes briefly after power-up, then off)
• Cannot access the unit's configuration utility, either directly-connected or through DIR-655 (I can in AP mode)
• Cannot ping the unit (Host unreachable)
• DIR-655 log shows no acknowledgement/response when the DAP-1555 is connected/disconnected (DIR-655's corresponding LAN LED does light up and I have confirmed that I'm using a good cable); DAP-1555 seems to make no attempt to connect to the router (it does in AP mode)
• No apparent response to power resets (i.e. no changes in any of this behavior)
• Unresponsive to hard reset attempts (via rear reset switch)- no power cycle or change in LEDs no matter no long I hold the reset switch

WHAT I'VE TRIED

• Hardware reset ("paperclip" switch on back of unit) with switch in AP mode- the unit seems completely unresponsive to this
• Hardware reset with switch in Bridge mode- the unit seems completely unresponsive to this
• Reboot unit from configuration utility in AP mode
• Restore factory defaults from configuration utility in AP mode
• Reload firmware from configuration utility in AP mode (even though firmware is the same)
• In each case, I try to access the unit from its default IP (http://192.168.0.50), the static IP I had been using (http://192.168.0.199), and its friendly name (http://dlinkap), and I've tried from both VISTA and XP laptops connected either directly to the DAP-1555 or through the the DIR-655 with the DAP-1555 also wired to the DIR-655

Any suggestions?  Is there something really obvious that I'm missing?  I'm at wits' end and I really need to get this thing online again, as several devices depend on the network connection.  I welcome ANY information or suggestions and thank you all in advance for any help.

C'mon, the DAP-1555 IS a platinum product.....  A little help?

To be honest it sounds like the unit is bricked.
Can you ping either the default IP or the IP you assinged?
How about directly connected to a PC?
Do the lights on the front of the unit display any erratic behavior?

Yeah, I've tried all that.  Can't ping or access the unit in any way when the switch is on Bridge mode.  Whether connected directly or not.  The lights do seem normal, but nothing else is.

Thanks for taking a minute to respond; I've concluded that it's bricked too. I've never had trouble with D-Link products, so haven't had to get warranty service, but I'm hoping they are responsive and replace it fairly quickly. We'll see....

I apologize for the inconvenience, I wish there was something we could do for you here.
If you like I could handle the RMA for you personally. Let me know.
I'll PM you my contact information.

Lycan,

Thanks so much for the generous offer, but I'm already in touch with D-Link and it looks good so far. I just hope this isn't some broader problem with the DAP-1555, as I really like the unit when it works.  I plan to replace it give it another chance.

Thanks again.

I'm glad to hear it. Please feel free to PM me if needed. I'm almost ALWAYS here. lol.
