Upgrading past firmware v1.0.12.120 for RAX 50

So I finally updated to the latest firmware release (V1.0.17.142_2.0.100) several weeks ago and now I am seeing the same problem as before where the wifi through the WAN will suddenly stop working. I can still log into the router admin screen and a reboot fixes the issue but before I updated this had been rock solid for the past 2 years without needing a restart unless I made a change or my ISP did. It appears as though non http/https traffic is still working since the IOT devices that I have connected seem to work. I also am able to see that the WAN connection still looks available, I was able to go out and check if the firmware  was up to date from the router. However, I cannot get to any web sites or ping any internet sites like google or yahoo when this happens and nothing that uses wifi works. I tried looking at the logs in the web interface but they do not seem to show anything but access to the admin portal or denial of service messages when this happens. Are there different ways that I can troubleshoot this?
