does anyone notice the same problem as i do when in starbucks using your laptop with att wi-fi.On the weekdays all the stuff i look at loads fast and videos on youtube play fast.But starting on friday night about 4pm and all day sat. and sunday,when everyone is not working and using the wi-fi everything i look at pauses every 5 seconds and all content loads slow.54.0mbps on my systems tray icon.Is this starbucks fault or att's fault.
