WiFi - this is killing me
I really need some help with my wifi issues on my tab. I am tethering from my Thunderbolt and as you can see in the picture, my signal strength is as good as it can get. However, the websites are not loading at the time of the picture, the weather will not refresh and my words with friends won't update. All of this is sporadic. After I took the screenshot I went right back and hit refresh on the browser and it worked.
Here's a good example; just a few minutes ago I downloaded Swiftkey from the Amazon appstore and no sooner had it downloaded and installed when I went to the browser and when it was trying to load the homepage of Google it tells me there's no connection when I have full signal strength. Also, what do the colors of the wifi signal bars mean? Sometimes they're gray and other times blue. But I can't see a direct connection between working data and error messages. Sometimes gray works and sometimes it doesn't, same way with the blue bars.
Basically, I am connected to wifi and the data connection comes and goes in a matter of seconds. Last night it worked for an hour or two no problem. It's not my tethering because I updated the app, reverted back to what I had before and even tried another release. My Acer A500, my girlfriend's iphone and ipad, and my ps3 all connect to the network and have no problems. I know it's my tab, I just don't know how to fix it.
I even tried replacing the wpasuplicant, it makes no difference with or without the new one so I just chnaged it back. Plus, the tab has no problem seeing and recognizing the phone's network; it just connects and stops working. It doesn't even tell me I'm disconnected, it shows me being connected even when it doesn't work.
I'm stumped guys, this shouldn't be so difficult. I really like the tab, and I don't want to have to get rid of it. I find it strange that no one else (that I've seen anyways, forgive me if I've missed it) is having this problem. I have seen wifi issues listed on here about not being able to connect, but not dropping out like mine.
Sorry for writing a book, any help is appreciated.
