Don't update Nighthawk X10 R9000 to Fireware V1.0.4.28 or you'll brick your router.

There is a fix, hook up an old router and get the R9000 RMA'd :smileytongue:

But seriously, I wouldn't wait on a fix, they still have the 'brick making' firmware available on their website and people are still updating to it eventhough this problem has been identified and is basically catestropic. If I was a NetGear higher-up I'd be like "ffs take the faulty firmware offline until we can fix this before we brick anymore of our products!" and then I'd fire the person who pushed out the update without proper testing. 

I got the impression some people can still use their R9000 and it just won't save settings once it's restarted but myself and some others are having further complications causing the router to be unuseable so if yours works okay, I'd just set it up and hope the power doesn't go out and get an RMA and have a replacement sent out (it will only cost you $17 for NetGear to replace your router that they broke).  But start the RMA process ASAP.
