X10 R9000 Firmware 1.0.4.12 DO NOT UPGRADE(WILL BREAK 5GHZ)

I'm extremely disappointed with this router and even moreso with the customer service! A month or so ago I updated the router to 1.0.4.12 firmware but I noticed sometimes afterwards that the devices would randomly drop offline but then connect back up. If you are streaming a movie or downloading than thats not acceptable. After some troubleshooting my network I determined it was the router. I downgraded the firmware to the previous version and the problem was solved. I called customer service to discuss and they wanted to charge me to troubleshoot since I purchased it about a year ago. My problem is that if the issue is with your faulty firmware I shouldn't be charged. Now what I haven't mentioned is that the only reason that I purchased the router in the 1st place was to run the plex server but after several weeks discovered that a 12tb raid HD is incompatible. So now I had to purchase another computer to run my plex (upgrading from an HP home server) because I wanted to push 4k. I went back and updated the firmware to the latest and now my router is bricked! So I purchased a computer and a $500 router to do what I was already doing and now its not working. To say that I'm not happy with Netgear is an understatement! Fortunately I was running with cable modem/router and I just called the cable company and had them flip that on. So I purchased the router for one reason but was unable to use it for that pupose and kept justifying the purchase  by other features, after it having no more use to me than a low end router that cost $50 my last thought was that I can use it with the gigabit service thats about to come into my house but now its not working at all...What is the chance that I will will be choosing netgear in the future.....0. Although I have use netgear routers in the past (and actually just installed one in my daughter's college dorm).I am usually very loyal to a company and although I have purchase the last 3 or 4 routers from a competitor I jumped ship for the the plex feature. Painful lesson learned!
