I have a directory shared on my computer Optimas-PC. The problem is that I want to access that file fom Optimas-LT. Optimas-LT is a laptop while Optimas-PC is a desktop computer connected via LAN. For some reason, it wouldn't let me connect to the computer so that I could access the directory I was sharing. I could access it from the other computers, but I couldn't even get a ping to the computer.

If I ever try to connect to it, I get this:

enter image description here I tried mapping the drive an got this. I assume this unidentified device is the issue. Can anybody shed some light on the situation?

enter image description here

For what it counts, I have a Linksys router. Other than that, we have no other devices.

EDIT

Alright, here is all the details:

Optimas-PC (The Desktop):

IPv4 Address :: 192.168.1.107

Subnet Mask :: 255.255.255.128

Optimas-LT (The Laptop):

IPv4 Address :: 192.168.1.103

Subnet Mask :: 255.255.255.128

I've not set up anything for the router itself for the most part. I'll check it out now and edit to reflect the results. The Unknown question mark is something, I'm not sure though, it isn't a second individual device - I know that.

What is OPTIMAS-LT connected to? What is the top unknown? –  David Schwartz Aug 9 '12 at 4:05
    
The subnet mask on the Optimas-LT is missing a 255 (it should be 255.255.255.128). Was that a typo, or how it really is set? –  Everett Aug 9 '12 at 4:42
    
@Everett :: Sorry, just a typo. Thanks for the catch. –  Xan Aug 9 '12 at 4:50

It is likely that the Laptop is connected wirelessly through an Access Point (one of the question marks you show). Is the AP (Access Point) acting as a DHCP server for the Laptop? What is the Laptops IP address? What is the IP address of the PC? What are the subnets for each?

The reason I ask all this is because right now my answer is: Your computers are on two different networks. In order to prove this wrong (or right) I need the answers to the questions I asked.

Do any of these settings seem promising? i50.tinypic.com/30m4ht0.png –  Xan Aug 9 '12 at 4:23
    
Whatever you pulled that information out of is an Access Point. It may be a router too, but it is an AP. –  Everett Aug 9 '12 at 4:44
    
Can these two computers (Laptop and desktop) ping each other? –  Everett Aug 9 '12 at 4:47
    
Nope, they cannot. These settings were also located in the Routers Control Panel under Advanced Wireless Settings. –  Xan Aug 9 '12 at 4:49
    
Okay, now we are getting somewhere. Are these static IP addresses, or is DHCP turned on, on BOTH computers? –  Everett Aug 9 '12 at 4:51
