EA9500 - fw ver 22.214.171.124089- single PC randomly kills entire internet
Have and EA9500 wifi router with comcast cable internet through an Arris surfboard T25 cable modem.
6 HP 6200 Elite PCs in use for decade on home network all DHCP except #4 & #5 (freenas). Wiped the target PC (we'll call it #6) and reinstall windows 10 clean. Since this activity at random times (every few days to once a week) entire internet would become unavailable and/or NAS service (freenas8) running on #4 & #5 HP Elite PCs would become unavailable. Removing ethernet or powering off would return freenas service. No IP conflicts in all cases. In the case of entire internet not available I cannot ping gateway (WIFI router IP 192.168.1.1). Unplug or power off target PC (#6) and internet would return. Scanned PC using multiple suites for malware/virus/etc return clean. Tried moving port around where this pc plugs directly into the linksys wifi router. Ordered exact replacement PC thinking it was hardware issue (bad nic??). Install clean windows 10 OS. No apps, no extra drives... now happens less frequently. Maybe once every 2 weeks. Made some adjustment in windows OS to only use IPV4 (was IPV6 by default???) Still having the issue of entire internet becomes unavailable at random.
