I have a new MBA 11, 1.4/2GB/128. Updated to 10.6.5 My wireless speeds are much slower on the new MBA. In my apartment, where I pay for fast u-verse speeds, my older 2007 Blackbook (C2D, 2GB, 10.6.5 also) gets speedtest.net download speeds regularly between 10-11 mb/s. The new MBA, in the same location in the apartment, gets between 1.2 and 1.7 mb/s. Same network, everything. Apt. network is password-protected. I get the same issue at my home in California (I commute between Houston and CA). MBA has difficulty acquiring and maintaining my unencrypted home network - also slower speeds. Apple support had no suggestions, and the information I could find online was mostly for older MBAs under 10.6.4. I can take it to the Apple Store for a test but wanted to see if anyone else was experiencing the issue. The MBA is otherwise fine and functional for basic surfing and work but it takes FOREVER to download anything (2 hours for 10.6.5, for example). Driving me nuts. Any suggestions? Thanks!
