Ping Test
Verify that the network card is capable of pinging or seeing itself by using the ping command. Windows / MS-DOS users ping the computer from a MS-DOS prompt. Unix / Linux variant users ping the computer from the shell.
To ping the card or the local host, type either
ping 127.0.0.1 or ping localhost
This should show a listing of replies from the network card. If you receive an error or if the transmission failed, it is likely that either the network card is not physically installed into the computer correctly, or that the card is bad.
To Ping to another system: Ping <network address of other system>
Another method of determining network issues is to use the tracert command if you are a MS-DOS or Windows user or the traceroute command if you are a Linux / Unix variant user. To use this command you must be at the command prompt or shell.
Once at the prompt type:
tracert <network address of other system>
or
traceroute <network address of other system>
This should begin listing the hops between the computer and network devices. When the connection fails, determine which device is causing the issue by reviewing the traceroute listing.

Wireless Troubleshooting
Make sure the router's DHCP server is set to assign IPs using a non-overlapping range in the same subnet as the LAN port address. If your router's DHCP Server is set to filter access by MAC address, add your client's MAC address to that "allowed device" list
Check your router's Log or Status page to verify that an IP address is indeed assigned to your wireless client whenever it connects.
Receptions
Anything that can alter the electrical properties of the atmosphere and anything that can generate noise at radio wavelengths has the potential to affect your wireless network. Even a faulty street light outside your home can cause interference problems inside. As with any antennae, there must be no obstructions in the way of the connecting systems
USB Based Wireless
On a computer that is running Microsoft Windows XP or Windows Vista even when there are five or more wireless network connections available, the Wireless Network Connection dialog box shows that there are a maximum of four wireless network connections available. This problem occurs only when you use a USB-based wireless network adapter.

Description of TCP/ IP
IP Address
A computer with multiple network adapters has an IP address for each one,
Subnet Mask
Used in conjunction with the IP address to determine which subnet an adapter belongs to. At the simplest level, communication is only possible between two network adapters when they’re in the same subnet.
Default Gateway
IP address of a computer or router, on one of this computer’s local area networks, that knows how to communicate with subnets not present on this computer. For an Internet connection, the default gateway is a router belonging to your Internet service provider, and all access to sites on the Internet goes through it. For an ICS client, the default gateway is the ICS host. If you use a hardware router, it serves as the default gateway.
DHCP Server
If an adapter is configured to obtain an IP address automatically, this is the address of the server that provides it. It could be your ISP, an ICS host, or a hardware router.
DNS Server
IP address of one or more Domain Name Server computers. DNS servers translate Internet names

LINUX
NOTE:
Windows XP service pack 2 and service pack 3 contain security features that block linux from accessing the Windows PC even with file sharing enabled and firewall disabled. Windows XP version 2002 without the service pack installed is fully functional with file sharing and firewall features enabled.
You need to edit your SMB.CONF file :
Open Terminal
Type: SUDO BASH
Password will be your own login password
This will give you root privelages.
Type: GEDIT SMB.CNF
This will load a graphical text editor for the SMB (samba) file
Lines to edit:
Workgroup = <your own workgroup name>
[homes]
Home Directories change browseable to yes to enable windows systems to see your files. Note you cannot enable Linux core files as being shared (VAR)
Close Terminal
Your network IP address best used: 198.162.0.1.......198.162.0.2........192.168.0.3
(change only the last digit per system)
In my experience changing anything else results in a non working file share.
The 2 most important item you need to change is your Workgroup name and file sharing.
