Get MySettings app, WiFi Buddy app change some settings in the time outs there are two of them. I use to use that DIR-615 A1 which was the best for wireless but DLINK doesn't support A1 hardware anymore. C1 is the same as Trendnet TEW-652BRP which now both can do DD-WRT firmware. Still even using DIR-655, Belkin N+, Trendnet TEW-673GRU, best and the cheapest is the EnGenuis ESR-9850 is what I use today my review on the wireless router. Best to use mix mode is stable if you have G & N wnodes (wifi devices). Well anyway I use two APNs (access point networks) now for the two tablets. So I can use the tablets anywhere even outside in the woods or on the back porch. 802.11b,g,n set to mix modewireless channel set to autowireless scheduling set to nonewireless security set to wpa2 aesThere is app for wifi analyzer might want to give that a spin to see how well your wifi router and tablet are doing?
