Im On a slingshot Express Everyday 25GB plan and a dlink modem one of those free ones that i got off a friend internet kept cutting out and thought it was because the modem was so cheap went to dse powerhouse and said i wanted the best wireless modem they offered me a dink one or a linksys and i wasnt very keen on the dlink, so got the linksys one its a wireless-g adsl home gateway all in one solution... says its ADSL2/2+ modem, internet-sharing router, 4 port switch and wireless-g access point. the model number is WAG200G and i have set up the slingshot settings on the linksys settings page "192.168.1.1" e.g ----@jetbuster.co.nz etc etc even though thats not the address but an example. any way its much better but it still cuts out now and then but im sure i dont have the settings correct but i have no idea what to do i tried getting the settings of the slingshot website and found them but had no idea what to do with them msn sometimes says theirs some kind of dns error or something but not very sure i dont know how someone coud help but im up for any suggestions etc... please help!!
