Can you link me to the power supply that's allowing 90 minutes of Wifi? I'm using the 5.25V 1A Adafruit one. I also have a 5V 1.2A, so I may try that to see if Wifi lasts longer.Andre-Acer wrote:Exactly same problem here! After booting my pi into Raspbmc after 2-10 minutes suddenly the wifi connection speed drops and is gone then. After rebooting or after plugging the dongle out and in again the wifi connection works for another 2-10 minutes.
I had the problem, when the pi was powered by the TV USB. Then I tried a Samsung mobile power supply. Then the Wifi exceeded to 30 minutes. Now I am using another 1,2A power supply and until now the wifi works for 90 minutes playing 720p material. Hopefully the problem is solved now. It seems, as if the power supply was just to weak.
