Hello everyone! I bought an wi-fi only 16gb iPad 1. At day 1 I jailbroke it using sn0wbreeze and upgraded it to 4.3.1. But I'm having some wi-fi issues. I can connect, but after a random amount of time (could be 1 day or 10 minutes), the connection fails without showing any warning - even the wi-fi icon is always there on the notification bar. But the iPad simply won't receive any data. I have to manually disconnect and reconnect, and then everything is ok again. Is this an iPad issue, or it could be a firmware issue? I live in Brazil, so I can't send it back to apple or anything like that. If it's a hardware issue, I'll have to live with that! many thanks!!!
