Hi guys, I'm new in the forum, I have a Dir-890L, updated the 1.10b07_beta in Dec, 2016, Last few weeks my ipad and iphone started to drop the wifi connection every time I tried to use them. In the last few days, I've experienced that my 2 Iphone 6 and 6+ can't get internet services thru the regular wifi channel from my router, I've to get on line as a "guest" and today my ipad internet and Nest not working with the regular wifi channel as well. So far I have to connect all of them with "Guest" wi-fi, anyone know why and how to fix it, thank you!
