R7000 firmware version 1.0.5.64_1.1.88 released today

Hi All

After upgrading to R7000-V1.0.5.64_1.1.88 from R7000-_V1.0.3.80-1.1.38 this week I am experiencing lots of disconnections from the Internet on both 2.4 & 5 wireless modes and LAN ports. When I check the logs it show every 15min or 30mins [Internet connected] IP address: XXX.XX.XXX.XXX, Thursday, Jun 09,2016 13:10:59. I have done all my checks (Like connect straight to the modem) and flashed the firmware in the correct way (Factory reset, manual config and power cycle). I must admit that l had the odd one or two disconnections with the previous firmware that's why I did the upgrade but it seems worse now. I am more concern with a stable connection rather than bells and whistles could someone advice me on a stable firmware to use for now until Netgear sorts this 3 year old problem out on what I see from reading the forums. My two laptops which one is connected to the LAN and the other on 2.4 wireless and four android devices which two are on 5 wireless and the others on 2.4 wireless are all suffering from the same symptom.
