CBS350-16P-2G --- %DHCPV6CLIENT-E-ILLGLOPTNLEN

[Travis L]

The error message I keep receiving is as follows: 

%DHCPV6CLIENT-E-ILLGLOPTNLEN: Illegal option length: option is 24, length is 0 in message type 7

I have unplugged everything from the network except for my pc and modem. The switch is on the latest firmware. I have turned ipv6 off in my settings on my pc. My modem is a Netgear C7000v2 running firmware V1.03.08. I am getting my dhcp from the netgear.
