If you want to play online games or use Internet applications, most will work without doing any port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Router to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using.
Instant Wireless® Series 10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up popup window. If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the LAN. For Microsoft Internet Explorer 5.0 or higher: A.
Instant Wireless® Series 15. I can’t access my e-mail, web, or VPN, or I am getting corrupted data from the Internet. The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500. For most DSL users, it is strongly recommended to use MTU 1492. If you are having some difficulties, perform the following steps: A. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the Router. B. Enter the password, if asked.
Instant Wireless® Series What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP.
Instant Wireless® Series your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is set to connect directly and that any dial-up is disabled.

Instant Wireless® Series What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard. What is a MAC Address? The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent.
Instant Wireless® Series Appendix B: How to Ping Your ISP’s E-mail & Web Addresses Virtually all Internet addresses are configured with words or characters (e.g., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. For example, www.yahoo.com is 66.218.71.87 (this IP address may change). Type it into your web browser and you will wind up at the Linksys home page every time.
Instant Wireless® Series Step Two: Pinging for a Web Address While the IP address returned above would work as your e-mail server address, it may not be permanent. IP addresses change all the time. Web addresses, however, usually don’t. Because of this, you’re likely to have fewer problems by configuring your system with web addresses rather than IP addresses. Follow the instructions below to find the web address assigned to the IP address you just pinged. 1. At the DOS command prompt, type ping -a 24.53.
