I've had my LG Optimus V for about 4 months now, and it's been great. However, the wifi has stopped working. My network is working fine. We have 4 other devices hooked up to it working properly. I have the password typed in correctly, and says the signal strength is excellent and the link speed is above 30mbps. If you guys have any suggestions as to what might help me fix this problem, I'd really appreciate it.
