Maybe this will clear up some issues people have with SMB.

It is best to set your PC with a STATIC IP.
Since I use Windows 7 I will give instructions on how to set it up in Windows 7.
For other O/S Set-ups please refer to Google Search.
Every router and configuration is different and mine is defiantly not the norm.
So again just use this as reference with your Google search.

1. Find your IP info.

Press your WINDOWS KEY + R
+

This will open the RUN command with Administrative privileges.
Type CMD and press ENTER

Now you have the Command Prompt. Type IPCONFIG /ALL and press enter.

As you can see there was ALOT info in there
You need to take note of SUBNET MASK, DEFAULT GATEWAY, and ALL DNS SERVERS (I only have one on here)

2. Getting more info from your Router

Open your favorite internet browser and type in the DEFAULT GATEWAY you wrote down earlier and press ENTER.
You will be prompted for a USERNAME and PASSWORD at some point in the next steps.
I have listed the defaults for the most common routers. There are hundreds of different routers if what I listed does not work the refer to http://www.answersthatwork.com/Download_Area/ATW_Library/Networking/Network__4-List_of_default_Router_Admin_Passwords_and_IP_addresses.pdf
If they do not work that means someone changed the defaults and you will either need to get that info from whomever change it or HOLD the RESET button on your router for about 30 seconds to revert it to default.
A word of caution if you reset it to default all wireless security info will also be reset and you will have to reconfigure that on ALL wireless devices you may own. You will need to refer to your routers instructions for information on this set-up.

LinkSYS/CISCO:
Username: admin
Password: admin

Belkin:
Username: admin
Password: (blank)

Netgear:
Username: admin
Password: password

Username: admin
Password: 1234

As I said before my set-up is not the norm so in your router you may have to click on STATUS to get the info you need or ADVANCED or somewhere else.
As for me I will be clicking on HOME NETWORK and ADVANCED SETTINGS

The information you want from here is the DHCP range and more specifically the starting range and ending range.
Mine is 192.168.254.100 – 192.168.254.200. You can use any IP in between those two.
I am using 192.168.254.100.
Be sure you note this information down.

3. Setting up the static IP.

Press your WINDOWS KEY + R
+

This will open the RUN command with Administrative privileges.
Type NCPA.CPL and press ENTER

This will open your network adapter settings.
You want to right-click on “LAN (Local Area Connection)”.
Next you should click properties.

You should now click on “Internet Protocol Version 4 (TCP/IPv4)” and click Properties.

After going through all those steps and getting all that info we get there where we have been going.
Click “Use the following IP address” and fill in ALL the blanks.
If you only have one DNS then leave the “Alternate DNS server” blank.
Then click OK twice.

4 . Setting up Your NETWORK SETTINGS.

There a different configurations you may use this is just the easiest.

Press your WINDOWS KEY

Click on “Control Panel”

Now click on “View by: Category” and Select “Large icons”

Next click “Network and Sharing Center”

Then click on “Change advance sharing setting”

Set your setting just like the pics below:

Click “Save Changes”

5 . Setting up a NETWORK SHARE.

Find the folder in which your Videos/Movies, Music, or Pictures are in.
I will use the the default Windows folders for this example.

Now right-click the folder you want to share and click “Properties”. I will use “My Videos”

Next click “Share”

Then click then drop down box and select “Everyone”

Click “Add”

Now we click “Share”

Click “Done”

Next we will click “Advance Shareing”

Check “Share this folder” and click “OK”

In your Network you should now see “Videos”. Take note of this name.

6. Setting up SMB on WiiMC.

At this point you should have a static IP (mine was 192.168.254.100) and a Network Share (mine was Videos).

Since I don’t have any way of pulling screenshots from the Wii at this time I stole some from Google and edited them to suit this tutorial.

After Loading WiiMC Click Settings

Next Click “Network”

Then click “Add SMB Share”

Display name is whatever name you want your NETWORK SHARE to display on the main WiiMC screen
Share IP is the IP of the computer that has the NETWORK SHARE. (mine is 192.168.254.100)
Share name is the NETWORK SHARE name we had earlier. (mine is Videos)
If you followed the steps in “4 . Setting up Your NETWORK SETTINGS.” then you won’t need a username or password.
Click “Go Back” until you get back to the main screen and you should see “Videos” or whatever your NETWORK SHARE was in there.

That’s it your done. Give yourself a pat on the back and enjoy your new SMB share on WiiMC.
