welcome aboard dawg. nice phone, if you dont have a manual download one here;http://www.phonearena.com/phones/Samsung-Stratosphere_id5868/manual
see page 84. your wifi router should be set to a specific type of network security, ie wap, wep1 or wep 2, and it will also have a password. whatever it is, (and you may have to access the router with your pc browser to find out or check another computer that uses wifi to see how it is set up) set the phones wifi settings to use the same security type and input password. My phone wont connect on wep2 so i had to go down to wep1. if you are still having trouble figure out what type security and pwd and call cust service or me. my number is in my profile. good luck see ya soon.
