Linksys Wireless Router :: Why Doesn't E4200 Wireless Router Show All Attached Devices

I recently installed some wireless IP cameras and when attempting to re-install a camera I went into the DHCP Client table to verify which IP a camera was using to set it up, but I could not...and still cannot see any of my cameras in the table even though I can access three of them directly through the IE web browser. I initially power cycled both the E4200 router and Motorola cable modem, and then later just the wireless router...but I still do not see the devices connected. I currently have 2.0.37 firmware even though I was told by Cisco support that there was a later version available, just before being informed that I do not have support available and could purchase it. I attempted to locate a newer version, but the online upgrade portion of the Cisco Connect software searched the net and then states that I have the latest version available. I also opened a Firefox browser to see if maybe my browser was causing issues, but the same limited table appears without all entries available. I even opened the Cisco Connect software on another laptop with the same limited results. Other than a factory reset, get me E4200 dual band wireless router to show all attached devices through the DHCP Client table as it previously did approximately two weeks ago?
