My daughter recently joined Telstra, and was provided with a Motorola SB5101 cable modem. She was previously a Woosh customer, and had assumed (naively and wrongly) that she would get a router so she (and her flatmates) could all connect to the Internet.
I have since found the thread regarding router choice for the modem, but in the meantime I suggested she just plug her PC in to the Ethernet port with the cable provided by TCL.
She has never been able to get a connection. The lights on the modem appear to be OK, TCL support say they can connect to her modem, her IP settings (which all had to be entered manually) have been double-checked, and she has tried using another computer. She even disabled her firewall because TCL told her that she must have a "firewall problem". I am trying to help her over the phone (I live 4 hours drive away) and I am running out of ideas. Her computer is running Vista.
Any suggestions? Or should I just get a router and start there - I am concerned that if her computer wont connect, then a router wont work either.
PS. I got her to try another cable too, but seem TCL supplied one I would expect that to be OK anyway. She has never had any connection problems before using other routers on the same NIC (It is a ~2 year old Dell notebook).
