Regarding the dp-301p+ and how to reset.
Unfortunately I could not find a reset button on this device when I needed to erase the ip info I had manually saved via the web interface. This really surprised and annoyed me to no end. Was it such a hassle to include one?
What made it especially difficult for me was the fact that I could not log into the web interface with the ip I had chosen for reasons unknown. So my only choice was to reset using either a CONVENIENT button (assuming it had one) or the PS admin software it came with. I gave the PS admin software (comes on the cd that came with the print server) a shot and it worked.
However there were a few caveats. First you have to manually set the ip of the PC the software is run on to a subnet/ip address that is able to communicate with the ORIGINAL IP the device came with: 192.168.0 10. So I set the PC to 192.168.0 22 with a 255.255.255.0 subnet, ran the PS admin software and voila, it saw the print server. The software itsef is self explanatory, you can choose to 'reset to factory defaults' or change the ip to whatever you want.
Also the PS admin software has to run on XP or lower. It won't run on anything higher: vista or win7. Luckily I had my trusty xp laptop with me. Another thing: I could not find the PS admin software on their website but I'm sure a google search might turn up a hit somewhere else. If also else fails, I'm sure a call to tech support will result in either them sending a link to you or telling you where you can get it.
