I apologize in advance as I am not very network savvy.
ER Lite 3 has been running very well for a few months now on v1.9.0 until this evening.
It is a very basic setup with eth0 as WAN, eth1 as LAN. No VLANS, a few port forwards, and basic QoS profile enabled.
I have 120/20 internet from ISP and starting this evening it has dropped to 20 down (if I'm lucky) and 1 up.
Direct connected to Comcast Business (basic) modem and got 124/24 speeds.
I tried a simple ping of google.com from command prompt (win 10) and lost 2 of 4 packets.
I have a dumb 16 port switch for LAN. Ran a file transfer from 1 pc to another and got 112 MB/s.
I have not messed with any of the CLI or deeper capabilities and have not even logged into the router in over a week before tonight.
I tried a simple reboot to no avail.
Any help would be greatly appreciated!
