I have an Archer A2300 that's been working for about a year since I got it. I have an external hard drive hooked up to the USB 3.0 port. Twice in the past two weeks, I've tried to access the files on the external drive and found that the drive appeared to be empty - with all of the files missing. Each time I was able to restore the files with recovery software. The first time it happened, I thought it was a bad drive, so I bought a new one and plugged it into the A2300, but now the same thing has happened to the new drive.

Each time this has happened, I tried to log into the web interface of the A2300, and instead of seeing the regular log-in screen, I saw the screen that asks me to set up a username and password for the first time. When I power-cycled the router, it went back to the regular login screen, but the files still were missing on the external drive.

Has anybody else ever seen this or have any thoughts on what's going on?

Thanks.
