Hostname
  

c-61-123-45-67.hsd1.co.comcast.net

As can be seen in the above example, this hostname has the IP address of the computer, in this case: 61.123.45.67, in addition to his the hostname contains other data such as "CO" for Colorado, and Comcast.net, which is the ISP hosting the customer.

When referring to an Internet web page or location a hostname is more often referred to as a domain name. Hostname is also a command that can be run on some versions of Microsoft Windows and Linux.

Configure Wireless Router 

Configure your wireless router, we'll use Linksys WRT54G Wireless Router as an example. This router supports 802.11g and is backward compatible with 802.11b standard. The authentications supported are WEP, WPA/WPA2 authentication with pre-shared key or RADIUS server. In case you plan to get a new router, I recommend you to get one of these wireless routers.

Read the router manual before starting to configure it. This is useful for you to understand the router features and how to configure it. If the manual did not come with the router, you can download it from the vendor website. Sometimes the vendor will prepare some quick setup wizard to expedite router configuration, but I’m not going to explain this method here. I will explain some important and common settings which will be found in most of the wireless routers from different vendors, so you can use the wizard to start the installation and then check out the details here. 

Also register your product at the vendor website so you will be notified of firmware update, security alerts and all other product related information. 

Open your web browser (Internet Explorer, Opera, Netscape Communicator), then type http://192.168.1.1 and press “Enter”. This IP address is the factory default IP assigned to the router.

In this scenario, I set the computer IP as 192.168.1.10 (you can set 192.168.1.X, X= number between 2 and 254), netmask as 255.255.255.0 and gateway as 192.168.1.1.

After that, the logon screen will pop up, type in the default user name and password. You can find the default username and password for routers below.  Log on to the router web-management page.

WAN (Wide Area Network) Setting

First go to the Setup tab and click Basic Setup.  This is the place you set the public IP address provided by your ISP in order to access Internet. It can be one of 6 options:

1. Automatic Configuration – DHCP - Choose this option to obtain an IP address automatically from your ISP. (For most cable modem users). Optionally key in a name for this router. The default MAC address is set to the WAN’s MAC address on the router. Sometimes you will need to clone MAC address under MAC Address Clone tab. This feature is required by cable modem users with the service registration via computer network card’s MAC address. That means the ISP will authenticate your network card’s MAC address whenever you use the connection service. If so, you will need to click clone MAC address in order to clone the computer network card’s MAC address to your network router. If you are not sure, check with your ISP technical support. Click here to check MAC address of network card.
2. Static IP - Choose this option to set static IP information provided to you by your ISP. You will required to type in all network information manually if select this option. This option is mostly used by business users. Lot of works if use this option, try to avoid this if possible.
3. PPPoE - Choose this option if your ISP uses PPPoE. Your ISP will provide you with a username and password. This option is typically used for most DSL services.
4. PPTP - Same as PPPoE, This option is mostly used by DSL service users with provided username, password and IP information.
5. L2TP - This option is mostly used by DSL service users is Europe with provided username, password and L2TP server information.
6. Telstra Cable: This option is mostly used by DSL service users with provided username, password and Heart Beat server information.

If you are a cable modem user, choose the Automatic Configuration – DHCP option. I won't clone MAC addresses because the service registration is tied to cable modem's MAC address.  

LAN (Local Area Network) Setting

At the same setup page, set up the IP address for the router. This will be the router/gateway IP address that you will set on your network computers. The LAN IP address is private in your home network and cannot be seen from the internet. I set my router with IP 192.168.1.1 and subnet mask 255.255.255.0.

DHCP (Dynamic Host Configuration Protocol) Setting

Most of the routers have a built-in DHCP server. The DHCP server will automatically assign an IP address to the computers in your wireless network. At the same setup page, you must specify the starting IP address, number of users and lease time. Lease time is the length of time for the IP assigned to the computer. For this case, the starting IP Address is 192.168.1.2, maximum dhcp users is 50 and the Lease Time is set for 1 day (0 minutes).       back to top

SSID and Other Basic Wireless Setting

Now click Wireless tab and you will see Basic Wireless Settings. These are unique features for a wireless router, it’s not available for wired routers.

Wireless Network Mode – 3 wireless operating modes are supported, it can be 802.11b (B only), 802.11g (G only) or both (Mixed). I selected Mixed, so that wireless clients with 802.11b or 802.11g wireless network adapter can join the network. Wireless Network Name (SSID) – The SSID is the network name of this wireless network and must be identical for all devices in the network. When wireless clients first start up, they scan the wireless frequency band for special beacon frames that content SSID sent by wireless routers or access points, finally connect to the network that is preferred by users. SSID is case-sensitive and must not exceed 32 alphanumeric characters. Change it and don’t use default SSID due to security concerns. I set the SSID as "home-network."  

Wireless Channel - There are 13 wireless channels (1-13) supported. All devices in your wireless network must use the same channel in order to function correctly. I selected 13. 

Wireless SSID Broadcast - If you enabled this feature, the router will broadcast SSID and would be detected by wireless clients on the network. For security concerns, I recommend you to disable it.

Wireless Network Authentication

Although wireless clients can join wireless networks without authentication, it’s risky.  So please set authentication on wireless routers, so that wireless clients can only join the network after successful authentication. This router supports legacy WEP and WPA/WPA2 authentication with pre-shared key or RADIUS server. Usually home users will use WEP, WPA personal or WPA2 personal security mode. WPA/WPA2 features are only available on 802.11g routers, whereas WEP is the only authentication feature supported by 802.11b router. 

Use WPA personal or WPA2 personal mode if supported by your wireless adapter. You need to supply a pre-shared key for authentication. Choose AES as your WPA or WPA2 algorithm. You can only use WPA-enterprise or WPA2-enterprise if you have set up a RADIUS server. This is the WPA/WPA2 authentication with RADIUS server instead of pre-shared key.

If your network card is 802.11b standard, you need to choose the WEP option, then set the passphrase with 64 and 128 bits encryption. You can leave group key as it is. This settings determines how often your group key changes. If your wireless network card can support WPA2, use following setting.

Most often it's not that easy to remove and get rid of Malware by doing a system restore, especially when it comes to Antivirus soft. This is a guide that will show you how to stop Antivirus soft processes, restore your internet access and remove Antivirus soft once and for all.

Reboot you computer by pressing F8 when the computer first starts and your computer should give you the option to start in safe mode (make sure you choose safe mode with networking)

This infection doesn't allow you to get onto the internet because it changes your Internet Explorer settings. We'll have to change the settings to allow you to get onto the internet to download the necessary utilities to remove the infection.
