I'm getting fine speeds on my iPad but on my new rMBP (not even a day old) it is like 1 or 2 kbps! i cannot download anything, browsing is fast as always but download speeds are slower than dial up. its happening from the time i first used it except that speeds were 30-40 that time which is also super slow. everything works well on my iPad and other windows/mac laptops so there is something with rmbp only. I've tried installing from several sources, still the same result. also, I'm hardly 10 feet away from my wifi router and the signal too is full. do you know anything about fixing it? thanks!
