Cannot mantain wireless connection between DPR-1260 and SBG900

I have a Motorola SBG900 cable modem with PCs working no problem. I have a DLink DPR1260 print server I'm using to connect the Pixma MP500 to the network. When I hardwire using ethernet cable from the DPR1260 to the Motorola SBG900, all works well. I can go through the wireless setup on the DPR1260, and get it to work wireless to the SBG900. However, when we lose power to the devices, the Motorola SBG900 can't find the DPR1260, unless I hardwire it back with the ethernet cable and go all the way through the initial wireless setup on the DPR1260.

The SBG900 is using DHCP, and the IP address for the print server DPR1260 always comes back as 192.168.0.10.

I can't ping the wireless print server after a power failure, but I do see it in the DHCP lease table on the DBG900.

Help, please? Power is inconsistent here.

Just to make clarify, you're unable to connect to it through your wireless router/AP using the address 192.168.0.10 or the http://dlinkps-xxxxxx PnP name it gives itself (where xxxxxx = the last 6 characters of the MAC ID printed on the barcode label), unless you connect an ethernet cable between it and a LAN port ?

After losing power does it show up again in my network places as a PNP device with the name DPR1260:dlinkps-xxxxxx?

And it still says 192.168.0.10 (dynamic) for IP Address on the Status tab, under Device Info, and you never have to change that, right?

What hardware and firmware versions do you have?  It tells in the upper right corner of the print server's config screens.

Does your LAN actually use the subnet 192.168.0.0?
Do you have an address reservation setup for the print server in the DHCP server?
What kind of router/AP is it?

You might want to invest in an uninterruptable power supply (UPS), btw... the spikes and brownouts associated with power going out and coming back on aren't good for electronics. I have one for computer stuff and another on my TV/stereo rack.

If the budget ever allows a UPS, I'll get one. I do have a decent APC surge protector. The last UPS I had only lasted a year. Too many outages.

The DLink print server has firmware version 1.12, the Motorola AP/router is version SBG900-2.1.15.0-SCM00-NOSH.

Yes, it is DHCP, supplied by the Motorola and yes, it does keep the lease.

The AP/router is 192.168.0.1, the print server is 192.168.0.10.

If I completely reset the print server, and start from default, I can set it up to run wireless. That is the only way it seems to work as wireless. The question is what part of the config is not saved and is lost in power outages.

I don't know, because I've killed the power on my DPR1260 numerous times trying to reproduce your problem and I couldn't make it NOT connect to my router in infrastructure mode as soon as it came back up. Oh... except it wouldn't connect wirelessly if I had a network cable plugged into it too... other than that I couldn't reproduce the problem (also running 1.12 on H/W version A2).

Is yours still under warranty? (they have a 1 year warranty.)

Is out of warranty at this point. I'llkeep working at it. Other than this one issue, it seems to work just fine.
