Bricked my first one. Lots of troubleshooting.

This thing works but takes a lot of trouble shooting to get perfectly stable and level. If you do anything wrong it WILL brick.

First board could only post with one RAM stick, returned to Amazon.
Second board worked fine for 4 months, than started getting random hard freezes, including in BIOS.  Updated BIOS, reseated CPU, triple checked all connections -- still freezing randomly, sometimes several freezes/day.
RMAed to ASUS, waited 3 weeks, got the same board back -- 2 freezes in 3 hours!
Called support, was told that they only reflashed the BIOS. Ridiculous!  Not sure when ASUS stopped being the reliable brand it once was..

Got it, opened the box, started it up, spent five hours configuring, machine said I needed to reboot several times; on last reboot (triggered by ASUS' own bloatware, the Webstorage program) I got "0xc000021a error" -- first recovery effort sent me to get a BitLocker recovery key that let me boot halfway before another critical error, second recovery effort and I can't get past the startup screen. There's a reason the price looks too good to be true. I've been told that this is standard trouble with a lot of Windows 8.1 devices and ASUS should not be blamed, so am adding an extra star, but I can see why so many people have switched operating systems...

DEAD ON ARRIVAL, Bricked with "E1" Overheat Error, 1 customer support rep for all of US, ship to China for warranty services.

Dead on arrival. E1 overheat "brick" error. I knew about the E1 possible error prior to purchase and thought I would be one of the lucky ones. I was not. That and the fact that there just aren't enough reviews on this specific model to make an informed decision. E1 error as soon as I plugged it in. The error cannot be remedied so, if you get the E1 error, your unit is a brick. You can try unplugging it and trying another time, unscrewing and re-screwing bulbs all you want. That error isn't going away.  No manual included, just 1 sheet of paper with what looks like photocopied instructions. The paper doesn't even have the model number listed on it. I sent it back and bought a comparable, updated model from a different manufacturer.

The battery will not charge no matter how many troubleshooting steps I follow!

I had 2 in a row that displayed  "waiting for main unit" however I looked at the troubleshooting section in the manual and I found the way to reboot it, now it works like a charm

I've had 2 of these get bricked after programming through the USB port and website. All buttons dead, u cannot even factory reset. They work well, but the underlying ROM is fully exposed and if it gets corrupted, you cannot recover.  Kudos for not requiring any special software like Logitech. Hope they iron out the kinks.

Maybe I got a lemon, but i'm not going to give it another try.
For the price you pay, I expect the drive to work right out of the box. Their website forum has alot of people tring to find a fix for this which depending on error message, is what you have to do to fix it. I say no no, should work right the first time. Returned it to Amazom, they have an outstanding return policy

Printer froze up and just displays error code message.  Going through support is a nightmare.  Printer lasted 5 months and now is bricked.

1st one's a dud... fans do not work and the card overheats, going to try a second. I guess I got a bad lemon.

Having problems with it already,  it may have been defected,  or I don't know how to use it

First one was bad, but second one was good to go. Lots of different connections for the mother board and peripherals.

Lots of issue (i have installed the last Bios and drivers) :
Sometimes USB's devices are not enabled, the automatic overcloking make blue screen and none of my USB's sound card works correctly (lots of glitch).

It was specular while it worked. . . but after a problem, ASUS customer service has been a continuing, on-going nightmare.

I had it for about five months when it suddenly died.  No power at all.  Took three days of working through on-line customer support answering the same questions over and over to get an RMA.  Shipped it back to them, and some days later, they then shipped it back to me. . . in the same *DEAD* condition.  Really?  This is not some kind of intermittent problem like it drops connections.  This is just dead.  It doesn't power on.

I called in and was told I would get a new RMA emailed to me.  Nope.

The next day I called in yet again, and this time I got the second RMA on the phone.  I sent it back in to them, and some days later, it was supposedly shipped back to me by FedEx but no tracking number.  That was on Tuesday (this is Saturday and the repair facility is in the same state as I am).  Still no returned unit, and still no tracking number.  I've tried calling in again and again this morning, and only get voice mail promising to cal me back.

After the parade of incompetence, I have no confidence in ASUS support.  Hopefully it will show up in the next few days and hopefully it will actually be fixed this time, but I expect better for a $220 router.  I bought this router because I wanted a reliable solution for my home networking.  Instead, I've got a headache.

*******
Update: After repeatedly calling (because needless to say, I didn't get the call back I was promised), I finally got a live person who could locate a tracking number.  Turns out that while they said the RMA was being shipped out Tuesday, it didn't actually leave ASUS until Thursday.  The rep also reported that the repair notes say that they couldn't fix my router, so apparently I'll be getting a refurb.  Hopefully that will solve my problem, but given the history, I'm somewhat skeptical.  I'll update after Monday (when FedEx will deliver the router) if there's anything worth reporting.

First one would constantly reboot. Amazon replaced and second works fine.

I read the reviews and bought 1. After trying for 3 weeks off and on to make it work I called in 2 separate network techs and am thankful it wasn't just me. Its a brick. Going to try to send it back.

Could not get Windows 7 to recognize it. Wasted probably 45 minutes fiddling with it. Bit of a disappointment.

Update 1:
Now my original USB hub is not working. No wireless mouse or keyboard on the laptop. Will reboot a couple of times to insure the Anker is fully uninstalled

Update 2:
Revising my initially scathing original review:
Anker is now installed.
After update after update and about 120 minutes later and finally working. I'm not sure what the issue was but it surely had me in a panic.

Make sure you have time set aside to fiddle with this thing before you start. Don't make the mistake I did and think, oh goodie it is here, let's just plug it in and then get back to work. It took over 2 hours fiddling with updating a bunch of drivers. No idea why. Darndest thing I have seen in a long time.
