Finally got tired of the wifi sucking on my Prime and called for an RMA. They didn't really ask any questions, just got my info and issued an RMA. I sent it in, they had it two days then I got an email saying it was shipping back to me. I tried to look up what they did to it, but their website doesn't show any details..just something like "received, tested, repaired, shipped". So I have no idea if they actually repaired anything on it but I'm hopeful that when I get it back, something has changed for the better.
