Verify that there is a default gateway assigned. Your network will function fine without one but, it is required to access the Internet.
I am running XP OS and I installed a Airlink model AWLH3026. It recognizes my wireless network but it will not connect to the internet. If I try to launch a browser, I get the message "Page can not be displayed." Is there something that needs to be set on my router? My router is a Linksys model BEFW11S4. Thanks in advance.
