Since you are having trouble with seeing devices across the wired/wireless boundary of your router/AP, you may want to look for a setting in your Belkins (probably under the advanced tab of Wireless) called "AP Isolation". This isolates the wired and wireless sides of your network. It may even appear to be disabled right now. So lets just manipulate that a couple of times to make sure it is doing what we want.
If it is off, turn it on and hit Apply (or Update or whatever it takes to apply it). Then, go turn it off again. You may have to do this on both your router and AP. In what sequence I am not sure. It may only be available on your router.
Try that and let me know....

My C309a will not stay online. I'm running Windows 7 64-bit operating system and the all the current releases of software and patches I can find. I called and use chat with technical support at less 15 times. No matters who I talked with, it seems they just following a written script. Every time they ask the same questions and provide the same solutions. You would think they would have a database with the basic information on the individuals calling more than once, so that you won't have give them your e-mail address, your phone number, the serial number of the device, etc that you requesting help on and other base questions. I have requested to talk to a supervisor many times but apparently their is NO solution to the problem. I running my printer in a wireless mode. Not only does the printer shutdown but the Solution Center fails just as frequently. It states that the printer isn't connected. I been putting up with this since I purchased the printer November 4, 2009.
My solution to this problem is I keep the must a copy current software and driver downloaded on my PC so I can save time NOT downloading the same software every time. Today I was printing in the morning but when I came back from lunch it had vanished from the printer pool.
One interesting thing about this problem is previous to purchasing this printer I owned HP Photosmart C7270 All-in-One, and I had the SAME PROBLEM. I worked with the Technical Support staff until I was blue in the face. This printer I purchased in March of 2007. I finally give up hope and purchased C309a. HP was suppose to produce excellent printers so I thought I just purchased a poor printer. Before this I owned a HP Lasejet for years and NEVER encountered a problem. Now I wish someone from HP could tell me WHY they produced these failures and can't seen to find a solution.
As I read though HP Support Forums, I see many customers with the same problems, and I haven't read a solution yet. The messages on C309a go BACK to 2008. Could someone at HP provide an answer WHY there is NO answer YET?

The solution I found was posted earlier in the thread:
I've seen this exact same thing. In my case, I had a laptop that was connected to the network through both the wireless and wired interfaces. When I shut off the radio, the problem cleared itself in about 30 seconds."
Simply put, the printer will not operate correctly if I am connected both wired and wirelessly at the same times. The signals get mixed up. There is NO documentation on this, even though it makes a lot of sense. And the call centers don't know it either. But, ever since I started making sure that I didn't leave wireless connected, when I'm also connected using my wired local area connection, I have had ZERO errors connecting to the printer!

For those HP printers that have both Ethernet and Wi-Fi, connecting the Ethernet cable disables the Wi-Fi radio.
This is what we call a "one-Hot" connection. It's a conscious decision to help us work around an issue with the SW driver that would get confused when it would see the same printer over two different network interfaces if Wi-Fi and Ethernet were enabled simultaneously.
