What does the SH have to do with they are not handing out dns via dhcp -- would not matter what modem he uses.
Its not really a problem, he could always just set dns -- where its a issue is that he can not tell his router what dns to use to lookup the ciscofqdn it wants to lookup. Because its limited to only setting it via dhcp on the wan interface.
I don't get why they don't hand out dns via dhcp - every other isp I have ever seen hands out this info. Why are they not, would seem to be an issue on this scope - because someone else said they are using the same isp and they get dns via dhcp.
Because his ISP DOES hand out DNS via DHCP but for some reason he ain't getting it. (I'm on the same ISP)
