R7000 firmware version 1.0.5.64_1.1.88 released today

Hopefully you guys can help me.

I updated to the latest 1.0.5.64 firmware and ever since, I have had nothing but connectivity problems.

I used to have 1.06.28 and didn't have any problems.

This is what is happenning: Every so many minutes, all my wire connected computers lose access to the internet. I can see everything on my lan but nothing outside. Same goes for wireles at 2.4g. However, 5g works no problem. When I look at the GUI, it tells me I have internet access which is true but it doesn't share with the connected PC or 2.4.

I have updated the firmware, reset it and start from scratch, setting it up again. No matter what I try, it doesn't work.

I went back to 1.06.28 and the problem is still there although it took about 18 hours before losing internet from inside the lan.

Surely I can't be the only one with this problem?
