M4 base unit crashing, no internet
Hi,
We keep losing internet connection and as far as I can tell, it's the base unit of the network (3 units) that is going down. If I'm connected to the base unit my WiFi connection drops, if I'm connected to one of the satellite units the WiFi stays up but I have no internet. A reboot of the base unit only fixes the issue but I'm having to reboot at least once a day now. Units are connected wirelessly, they haven't been moved and were working fine previously.
When the base unit is down I can connect directly to the web interface of the satellite units by IP but not to the base unit. In the app either I can't connect to the network at all, or it shows the base unit as not connected to the satellites. I don't think there's any issue with the actual internet connection or ISP modem.
Any ideas - I did a factory reset on all units yesterday but the issue recurred again this morning and I had to reboot the base unit again. The system is under 3 years old so I believe it is in warranty. One thing I have noted when connected to the web-interface of the base unit is that the CPU is frequently spiking to 100% but I don't know if that is normal/expected.
