WiFi Problem?

I don't really know what's happening... But here's what's been happening on my Glo (fw 3.8)...

I last I used my wifi to sync just 4 days ago, then this morning, I tried accessing the browser but I always get this error that there's no network found. I have 3 other devices that are connected to my router, and they alk have internet access. So I tried restarting my router and my Glo, and it still won't connect properly...

Along with all that jazz, the main thing that's happening is I'll be able to connect to a network with no error messages via the settings menu. But if I go directly from the browser it will give that error message.

And it also seems that the password is not being saved, so everytime I try to connect it will ask for the password.

Also, when it connects, the signal strength icon is blank lines, like it's connected but the signal is really, really, really weak, not even a bar is shaded...

Funny thing is that I can browse, it's just that everytime I click on something, that error will appear and I have to re-enter the password again...

I really don't know what's going on, I hope someone, at least, can understand what's happening...
