My network speed on my MacBook Pro has plummeted in the past week. I did a Speedtest.net on my wife's iMac, connected by ethernet cable to our AX, and got the usual 10 / 0.3 Mbps speeds. On my MBP, I'm not getting 1 / 0.2 Mbps speeds, connected by n (b/g) wireless. I'm out of my depth on wireless issues. I can't think of any change in the past week that would affect this. I've got a few crude ideas to troubleshoot, but before I start a potential wild goose chase, I'm hoping for some savvier ideas.
