I have to say I have always had a poor Wi-Fi experience even when signal is powerful. It tends to lag no matter what. My Wi-Fi router isn't the problem. ISP is 25mbps down. It seems like maybe a poor kernel? It doesn't matter what rom I have used either. I don't know, but I pray for a solution some day.
no problem with WiFi here, I use wifi at work all the time and it works great for me. Wonder if you have a screwy wifi radio
I like titanium backup but it's not always a good idea to install apps using it. It's easier but not the best.
I guess I will just have to install then restore the 'data' from titanium.
