I've read a lot about the various WIFI issues, and I'm seeing random slowness on my download speeds (FIOS WIFI, 45mbps package). But my upload speeds remain consistent. Another issue I've noticed is my HSPA+ (my city does not have AT&T LTE) will randomly switch to EDGE for several minutes (in areas I normally have 4+ bars) then drop to 1 bar not indicating EDGE or HSPA+ for a minute or two, then to 4+ bars on HSPA+. And it's not just what the bars "show", my real-time browser speeds significantly decrease or stall. Anyone else experiencing the same?
