Connection changes

[HolySafari]

Hi, I really am desperate and i'm not sure if this is the right place to post this but i really need some help

So i switch internet provider and before it used phone connection dsl but now this company uses cable

so i have a netgear wndr3700 with gargoyle installed
i called them for support and they said i have to extend my warrenty for $100 for 6 month or else they would not help me

and i certainly do not got that money
so before under the conections tab i used pppoe with the user name and password and such
what setting should i put it in now? can anyone help me please?

Try connection type as DHCP

Nuuu
i got another problem
it seems now the wireless works so all the laptop can connect to the internet but my desktops cannot connect to the internet through the internet cables,

If i connect one laptop with wireless then all the wired connections shut down, so i can only use wired or wireless it's like one or the other

Are the ethernet ports down? they were fine just a day before is it some setting problems?

Please help

More information

It seems my internet provider only provide 1 IP through the modem
so when i attach the modem directly to the switch only 1 computer can be on at the same time

thus they require the modem to be connected to a router
but my netgear wndr3700 only broadcast the wirless and not through the ethernet cables

my setting under connections atm is "DHCP(wired)" should i switch to DHCP(Wireless)? because there is an option that says enable ethernet something

will that work?
