Hi. Thought I'd post this in case someone else has this problem. My Tab 2 10.1 recently began to re-boot every 30 seconds or so, sometime even getting into a re-boot cycle before I could sign in. I removed some recent downloads, thought the on/off button might be sticking, removed the micro sim card. None of this helped. When I switched the tablet to airplane mode the re-booting stopped. This pointed me to a wireless issue. Then I remembered using InSSIDer recently to look at the various channels being transmitted by nearby wireless routers and noticed channel 1 was the clearest so I switched my Cisco Linksys router from channel 6 to channel 1 (20MHz only). Did not cause a problem to my wife's iPad or my Samsung S4. Had not used the Samsung Tab2 since this change. Switched my router to Auto 20 or 40MHz and Auto channel and the re-booting issue went away. Hope this might help someone else.
