Hi Wamug, I've got 2 MacBook Airs here with identical specs, both running 10.6.6. Both are connected to the same network connection via the same wireless network (Time Machine).
One gets 0.30Mb/s download speed (when measured using Speedtest.net), the other gets 53Mb/s (as do other computers on the network). The slow network performance has been consistent for some time. The same laptop connects to other wireless networks and network performance is fine. I've been through the Network preferences panel, and checked all settings - they are the same on both computers (well, the Ethernet IDs are different, and one has an IPv4 address of .1.102 and the other .1.105). I've tried renewing the DHCP lease, no impact. In other words, the specs and settings seem to be the same. The Time Capsule is V7.5.2 with Wireless Security WPA/WPA2 Personnel Channel 149 (Automatic), 2 (Automatic), Wireless Clients: 8 I've checked the slow Macbook air, it has 99Gb free HD and 500MB free memory. CPU is idle other than when performing network tests. It runs normal applications fine, not slow in any other respect that I can see. Does anyone have any suggestions on what might be causing the slow network performance on this particular wireless network?
