After about 24 hours, the LTE WiFi Gateway slows down to about 1 Mbps for both up and down speeds. In my configuration, I am doing a double NAT so I have better control over my network. This slowness has only started yesterday. I have had virtually no issues with the gateway since I got it about 5 months ago. To resolve the issue I have to reboot the gateway. I tried rebooting my router that I connect to via WiFi, but it has no impact. Only a reboot of the gateway resolves this. My neighbor has also been experiencing the same issue prior to noticing it myself for a while.
Was there a firmware upgrade that was pushed out on the gateways? Is there a way to revert the version if that is the case?
