I have teh G3100, this is my second one as the first had a different issue, I've had this one maybe 4 months. Last night around 9pm it suddenly booted off all the devices connected to it via wifi. when they tried to connect back it said incorrect password. The password was correct, I rebooted and factory reset a number of times. I use the default password so there was no changing of passwords when I factory reset. Spent over 1.5 hours on the phone w/ offshore agents trying to get it fixed. Finally spoke to someone in NY around 10:45 this morning. at some point during the call all my devices suddenly reconnected to the wifi.
Has anyone else had this happen? have you been able to determine a root cause? No one I've spoken with has been able to figure out what happened or why and I'm concerned it will happen again.
