My MBA 2010 started having network issue a few month ago. The symptom is:
1. sometime, the network speed drops to 0B/sec suddenly and all connection died, then comes back after a few sec.
2. When downloading large files, the initial download speed was great, 2MB/s, but sharply dropped to 20KB/s after a few sec. And never increase.
I have another MacBook Pro on the same home network. Never had such issues with it. I also tried to download the same file from both machines at the same time or one after another. No matter which way, my MBP can consistently have 2MB/s speed, but my MBA only had 20K/s.
I had this issue with MBA when it was running snow leopard. And I thought it may deal with OS. So just upgraded to Mountain Lion (clean install). But still the same issue.
But when speedtesting with http://www.speedtest.net, MBA still works pretty good, 18mbps download, 4mbps upload. This really confuses me. I begin to suspect if my airport adapter is broken. Any help or suggestion will be appreciated.
