Sharing your WiFi Internet through the Ethernet port, Windows 7

1- Connect to the Internet (using WiFi)

2- Press Start button, Control Panel, Network and Internet, Network and Sharing Center, Change Adapter Settings from the list on the left side.

3- Right-click your wireless connection and select Properties.

4- On Sharing tab check in the check-box "Allow other network users to connect through this computer's Internet connection."

5- Check "Allow other network users to control or disable the shared Internet connection" check-box as well and press Ok.

6- Plugin the ethernet cable to your computer and the other side to another computer or an ethernet switch / router.

Category 5, cable standard

Category 5 cable (Cat 5) is a twisted pair high signal integrity cable type. This type of cable is used in structured cabling for computer networks such as Ethernet and ATM, and is also used to carry many other signals such as telephonyand video. Most Category 5 cables are unshielded, relying on the twisted pair design for noise rejection. Category 5 has been superseded by the Category 5e specification.


I usually use these cables in my robotic projects as well, as they come in a well packaged easy way and one can easily setup one protocol to use one color for one kind of signal :-)

Net use command in CMD

If you want to map a network drive from command prompt(cmd), you can write the following command :

net use (partition letter): \\server_name\share_name
Example : net use y: \\test_server\test_share

Find computer name with IP Address

Click start -> Write cmd in the text box(in XP you should click on Run first) -> nslookup xxx.xxx.xxx.xxx(IP ADDRESS)

Then you have computer name in front of you :-)

Mount a Windows shared folder in Linux

You made the switch to Linux and at least one Windows computer is still on your network. The old days when Windows and Linux didn't play together are long gone. You can easily set up your Linux computer to have read and write access to the files housed on a nearby Windows computer. If you've used Macs in the past, the process is practically identical.

Set up sharing on your PC
In Windows, choose the folder you want to share, right click on it and choose properties. In the Sharing tab, turn on sharing. Feel free to name your folder anything you want and ignore any warnings Windows gives about the name being longer than 12 characters.

Determine your PC's IP Address
You will need to give your Linux computer a location when trying to access shared folders. This location is your PC's IP address. In the Command Prompt type ipconfig and you will see your IP address (it probably starts with 192). My IP address is shown below as 192.168.1.117

Accessing the shared folder from Linux
There are two very easy ways to access shared folders in Linux. The easiest way (in Gnome) is to press (ALT+F2) to bring up the run dialog and type smb:// followed by the IP address and the folder name. As shown below, I need to type smb://192.168.1.117/Shared. If you have your Windows account passworded, you will need to enter the password to access the shared folder.

Accessing all shared folders from Linux
Linux automatically detects and connects to Windows networks. In Gnome, by going to Places and then Network you will automatically see all the Windows networks. You can then navigate through the Windows networks and connect to the shared folder. This is an easy way to manage your shared folders if you have many Windows networks with shared folders.

Making it easier
By bookmarking your shared folder you can access it from the Gnome menu.

Windows was unable to find a certificate to log you on to the network>MyNetwork

I am able to connect to the internet(I can load pages, messenger, everything) through my router but windows is giving me the message"Windows was unable to find a certificate to log you on to the network -> MyNetwork".

"Windows was unable to find a certificate to log you on to the network>My Network"That's caused by improperly setting the encryption to WPA-RADIUS instead of WPA-PSK on the client. The router and the client are both trying to find a RADIUS server with which to authenticate. Since you don't have one, it complains using Microsoft techno babble. Change the encryption to WPA-PSK (pre-shared key) on both ends.

Turned OFF machine that sends network signal ....

Something intresting came up last week here at work and it was that I patched up a network connection to patching panel, at the same time the equivalent network switch started lighting orange first and after a while lighted green. This is normal if there is a machine that is ON on the other side(where the cable ends up to), but the point here was that the machine was OFF and was just connected to the electric contact on the wall. So it means although the machine is off, but the signal can already be sent and it is logical as long as the machine can be turned on by a signal on network.

A good book to read

Linux Administration, a beginners guide(Fifth edition, 2009) is a very good book for those who have skills in Windows and want to learn Linux as well. I am reading the book right now and I enjoy every single page of it. I DO recommend this book ...
