broadband connections

we have recently moved from an ADSL@ connection to Cable connection.We  were told to purchase a cable adaptor CM450-1TLAUS.Then told it was not compatible with current modem and told to buy a C6300BD-1TLAUS modem.After a week of phone calls I was told that that modem was not compatible.What to do?Frustration is at overflow levels !!!

You should be able to use the CM450-1TLAUS with any router or buy the Telstra Smart Modem. The normal configuration for new cable customers is the CM450-1TLAUS combined with Telstra Smart Modem but should be able to use any modem. The main problem when activating is to make sure the CM450-1TLAUS serial number is registered in Telstra's database..

Does your current modem have a WAN port or LAN port that can be configured as a WAN port you would be able to use your current problem.

They tell me the Cable Adaptor is registered but the modem THEY sent is not compatible ???

[cf4]

What modem did they send?

Gateway Max C6300BD-1TLAUS

The Gateway Max C6300BD-1TLAUS is a cable adapter and modem combined. If it is registered you should be able to connect it directly to the cable and not use the CM450-1TLAUS. I don't understand why they sent you the Gateway Max C6300BD-1TLAUS it is no longer used for new connection.

Are they sending you the correct gateway to use with the CM450-1TLAUS (Telstra Smart Modem)?

They sent me the C6300BD to "plug" into the cable adaptor. My original modem ( when connected to ADSL2 ) was a TechnicolorTG799vac. I am very confused as I am not all that computer-jargon savvy ( although I do know how to attach wires to "like " sockets )Each technical "expert" i speak with tells me something different.

The C6300BD does not plug into the cable adapter it plugs directly into the coax. I would not use the C6300BD as this is outdated and has inferior WiFi. I would use the cable adaptor connected to the TG799vac. The TG799vac should work with the cable adapter.

When using CM450-1TLAUS and TG799vac what was the status of the lights on the CM450-1TLAUS and TG799vac?

Thanks for all your help so far. No, I didn't even try connecting to the old modem. I'll give that a go and let you know how we go

[Andi14]

Thank so much cf4,you're a genius.It worked, plugged the cable adaptor into the old modem, bingo !!! I wonder why the "technical experts" didn't suggest that ?? Thanks again
