Xbox 360 Slim is incredibly slow when connected to Internet

Hi there, So the other day my Xbox was running great as per usual but then after coming home from the gym, it became Incredibly slow. It took over 7 minutes to get from turning it on, to finally signing in but while during signing it, it disconnects me from Xbox Live then when I reach the dashboard I get the message "Some Xbox Live content is temporarily unavailable." I test my connection and it completes successfully with out it being slow or any errors. I have cleared system cache, deleted my profile and redownloaded it, rebooted my router, took apart my Xbox and cleaned out dust and yet nothing. It only works when I disconnect it from Internet. Do I need a new wifi adapter or what? Any help is appreciated. Thank you.
