I just got the 3g Samsung Legend 2 days ago. Pretty new to smart phones. I had no problem with wifi connections and did not need password to use it, but today after 5pm it says it "Authenticating" then it says "disconnected". Even though i did not need my wifi password before now it says it needs it. I have been able to get access to wifi no problem. I did enter my password from my home wifi and it still won't work. My wifi icon is also gone from my apps. Any suggestions?
