IP Conflicts are occurring when multiple devices are connected to Storage w/o internet access.
I've been playing around with iUploader after re-flashing Router mode with FW 1.06 (no restarts seen yet).
One of my connected devices is a laptop running Win 7. I lost full internet connectivity after the 505 rebooted on its own successfully when I inserted a usb stick. I just joined all the devices again without forcing a DHCP request to my main router for the gateway and DNS.
For iUploader's browser, I used the blue link at the bottom of the Storage page in the Web Menu as usual, except this time the sub-net had changed from yesterday. Now it was 192.168.0.100:8181 instead of n.n.1.100:8181. (More on this below**.)
I successfully uploaded a photo to the usb stick with the iPad and turned to the laptop.
There, I was getting Win 7 System Error -- IP Conflict on Network. Ok, not having the energy to track it down, I quickly re-joined all devices with full internet access, and the error stopped.
I was happy to see the error in Win 7, because my mobile devices don't alert me to this error condition and it's possible to waste a lot of time wondering why "No Connection."
**Ok, now that I have full internet access on all devices, I take a look at the Storage link in blue on the Web Menu Storage page, and guess what: the sub-net is now n.n.1.100:8181 (back to Linksys sub-net) and no more Win 7 errors are popping up.
For what it's worth, I have to conclude that it's better to establish full internet access on all connected devices.
