On the premises, we also have a Motorola G, Nexus 7, Samsung Galaxy Nexus and a Nexus One. All but the GNex have no problems with this router. The GNex is still stock, so it would appear to have something to do with these older Samsung phones running 4.3. Searching Google, someone suggested forcing the phone to use the 2.4 band, and doing so with the GNex doesn't completely fix it, but it does happen less often. However, I can't find a "wi - fi frequency band" setting in CM.
So, does anyone have any idea what's going on? And is there a way to force the Captivate to use the 2.4 band?
