Happy Sun, I upgraded the wireless at work to 802.11n, so I decided to upgrade the airport card in my macbook pro via the $1.99 enabler. It works awesome. At home I have a linksys wireless router that runs 802.11g. It works fine. However, I have another friend who has an old airport base station (with the latest firmware). When I go to his house. My connection is slow My download rate is about 3Mb's but my upload is like 7Kb. I haven't messed with my MTu's or any IP settings for that matter. Anyone have any remedies?
