We have been using the Samsung 4G LTE Network Extender 2 in our apartment since 2018 with no issue. Over the past several days we noticed that our cell service was quite poor and I checked on the Network Extender and it was stuck on "connecting to the verizon network step 8a of 14".
I did several reboots and a factory reset but to no avail. I was able to log into the device and it appears the setup is failing at Step 4: "Failed to reach the Initial Gateway". I also have an active alarm: "SYS IPSEC_DOWN". IPSec is reachable but not connected".
I confirmed DHCP is enabled and the Firewall is not the issue. I am using the xfinity xFi Gateway.
Any thoughts?
