Cannot see network shares over WiFi connection

[photoone]

I have a Cisco X3500 WiFi router

I have a wired network of several computers, all running Windows XP. Some of these computers have shared folders which can all be seen and accessed from all the computers on the network.

I have a laptop, also with shared folders.

When I connect the laptop to the network via a network cable plugged into the router, the laptop can see and access all of the network shares the on the wired network, and the laptop's shared folder can be seen and accessed from any computer on the network

However, if I connect the laptop via the WiFi, it cannot see the network at all, and none of the computers can see the laptop.

How can I change this so that the laptop becomes a true part of the whole network, i.e. so that files can be shared across the network to and from the laptop

NOTE: When connected via wither WiFi or network cable, the laptop can access the internet as can all the other computers on the network

What OS running on your laptop?

Wired ethernet has different address/mac, likewise with wireless connectivity, it has different mac addresses. Please check if your wireless connection is on the same home/private/public network.

The Laptop runs Win 7.

I will check the other stuff tomorrow, though I am sure that the IP addresses of the wired and wireless connections are different. I did IPCONFIG/ALL from the command window and I'm sure I got different results, but both in the same subnet, i.e. 192.168.1.xxx

Note. Forgot to mention that on the Laptop, "Computer>Network" shows "Cisco3500" whether it's wired or wireless connected.

OK.

On the wireless side (using a smartphone to check) the router has a IP address of 192.168.1.148

On the wired side (using ipconfig/all on one of the networked Desktop computers to check) it comes up with the following

Windows IP Configuration

Ethernet adapter Local Area Connection 3:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.17
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.15
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

I suspect these are not the Cisco IP numbers but those associated with the the computer's Ethernet card.

I'm not sure why I appear to have two Local Area Connections when I am certain there is only one ethernet on the motherboard. In "Network Connections" there are two Local Area Connection icons, the second one is called "Local Area Connection 3" and its properties says that is a "Microsoft Loopback Adapter" ??
