I bought an RB750 Gr3 "hEX" in April, and has been in service since then.
Unit has been updated to ROS 7.6, and has been functioning fairly well, until now.
I have been getting intermittent drops, usually recovered after 10 minutes or so.
Last night it went down and I could not get it up again, so switched to an old netgear. Still took some time to get it connected, but got that one going.
hEX when rebooted has always beeped once and gone to work. Now it beeps once then activity lights go out, then beeps twice more and doesn't connect to cable modem.
When it "double beeps, the USR light also flashes twice in sync with the beeps. I can reboot into standard config, but retains OS7.6. I can get into it with Winbox.
Just does not seem to be getting DHCP from modem, but old Netgear does. I tried to Netinstall fresh but it does not connect, no matter how long I keep holding that reset button...
So, does anyone know the beep codes, and what they mean? Nothing found in Docs...
Thanks!
