Since January of this year I have received 294 emails regarding Wifi problems that multiple ipod touch users had. From 294 emails I managed to fix 233 ipod touch devices and 19 was faulty and needed to be returned.
Other 42 Ipod Touch either did not get any responses back after I sent them an email or just couldn't get it to work.
Most problems occurred: - Wrong password Input (Admin password vs. Wep Key)
- 64Bit Encrytion vs 128Bit encryption
- Did not Release/Renew to obtain new IP
- Did not restart modem/router to acknowledge Ipod Touch
Some other problems:- Email did not work
- Sync with iTunes
- Safari constantly crashing
- Jailbreak was not installed correctly
