Hi,
I have been using the WZR-HP-G450H for a few days just fine up until yesterday.
The wireless connection seems to drop intermittently, it would come back up again after about 1 minute or so.
As you can probably tell, this is very annoying!
This dropout is simultaneous on all devices connected to it.
I'm talking about a macbook pro, an iMac and a samsung galaxy s3. Internet connection is fine over wired connection and the wireless LED indicator is always on.
I tested using wifi analyzer on android and it seems to show the wireless is broadcasting and disappearing every 2 or 3 minutes.
It is currently using the user friendly firmware version 1.86, which I have upgraded from the out of the box 1.85.
I'm out of ideas, hope anyone can shed some light.
