yes i had looked in there and saw that it shows all green,but is that the way its supposed to be,or is one actually supposed to be red,it does not give enough information.and if one is supposed to be red,then why is my internet act so sluggish,but the netgear modem says it is working fine.it didnt act like this with the modem rented from isp provider.

It looks like the modem is unable to connect to the ISP network. You will need to call your ISP. They may have to send a tech out to diagnose your line.
