Purchased a WRT54GS Version 6 router and set it up with Easy Link. All was fine hooking up desktop and wireless laptop but my sonâ€™s Macintosh was not connecting. Contacted Linksys and they told me to upgrade the firmware from the original v1.5.5 to v1.5.9. Followed their instructions after downloadingâ€¦. all lights are on showing connection to the internet but I have no internet on the desktop which is wired to the router nor can I even connect to the access point from the wireless laptop. If any one has any suggestions, please let me know.
