Hi all! New living arrangement has caused some headaches with my Mac Pro (Early 2008, Quad Core Xeon). Too far from the router to inconspicuously run cable, and house doesn't have any network infrastructure. Bought a Airport Extreme (0x14e4, 0x88) chip with Broadcom firmware (BCM43xx 1.0 (18.104.22.168.16). Installed, bluetooth is working fine (that took awhile to troubleshoot), shows 802.11 a/b/g/n, can connect to several networks, but can't even see the 802.11n network my 2010 Macbook Pro is connected to at -79 dBm from the same spot. Thoughts? Thanks in advance!
