Yellow Triangle No Internet?

[Hieya]

I went into were i can change the setting on the router using a browser and typing in the ip and click clicked on reset to default setting and i keep getting these black triangle and no internet access.I have done this:
Reset the router and modem
Pushed reset button behind the modem and router and took out the power.
Turned off the adapter and turned them on again.
Called my host provider and they say its my router.
tried "ipconfig /release" and then "ipconfig /renew"
and in cmd"admin" tried using the netsh commands :/
