My LM14 Mate 64-bit is mis-behaving. It is ignoring the DHCP from my router and using it's own settings for IP address. It doesn't matter if I set it to static either. After boot-up it just sets itself up as it was before, wrong. Something else too, the DNS server 126.96.36.199 and 188.8.131.52 come up. These are OpenDNS, LLC servers according to "who is". I erase these, set DHCP to automatic, re-boot and there you are... back again!
I do not have this issue with the 32-bit version running on another computer on same LAN. Just the 64-bit one.
