My home Optus cable internet isn’t working. I tried relocating the Sagemcom 3864V3 OP router to a better location but it wouldn’t connect to the internet. I have returned it to its original position. I have performed all the turn on/off resets on both the Netgear CM500V modem and the router. I have wifi but still no internet.
With an Ethernet cable connected to the router from my laptop, there Is still no internet.
Please contact me urgently
Hi - on the CM500V, do you have 4 green LEDs on - 1. Power, 2. Down, 3. Up and 4. Ethernet to modem OK - indicating healthy NBN link? The F@ST 3864OP connected from its WAN port to the LAN port of the CM500V with a Optus modem WAN LED indicating connection to CM500V and linkage to the Internet OK?
If so, can you reboot your PC and see if it connects to the Internet. If LED 4 is not ON and the Optus modem WAN LED is not on, there is a problem with your modem - only remedy is to contact Optus to verify or, if applicable, if you have access to another spare and compatible modem from family or friends to get you up and going whilst the replacement from Optus arrives.
Am I right to assume the DSL light on the router should be on ?
No. You have a cable service which does not use use DSL.
The Optus router is indicating you have Internet and WAN.
You indicated that "With an Ethernet cable connected to the router from my laptop" but the router shows the LAN light off. It should be on/flickering if there is an active LAN connection to your laptop.
So you can try ruling out a problem with the router by connecting the laptop directly to the cable modem . As long as your laptop has a default DHPC network config then a direct connection to cable modem box should work.
With the Router connected via the Ethernet cable to the laptop, the LAN light was on and steady. I could connect to Optus and log in. It says wifi connected but I still can’t connect to the internet.
I spoke with a friend on the mobile who talked me through sending a ping, but that failed.
Still lost, hopefully an Optus tech can get me across the line in the morning. Now is not the time for internet problems.
Thanks for your help.
Your CM500V appears to have 6 LEDs ON and maybe the 7th is not in use - is the 5th LED usually Blue and is it labelled for Voice or LAN Data/Ethernet? Do you have an Optus guide that shows you the status of the modem and their associated colour LEDs - Optus web links to Netgear, but you never know if Optus has modified any settings for their version.
The web page link for the Netgear Cable Modem shows 7 LEDs, the 5th LED is for Ethernet - It shows one Ethernet port and 2 Voice ports and the second non connected telephone port may explain why the 7th LED is not active.
If LED 5 is labelled for LAN and usually Green, can you try another LAN cable to join the WAN port of the Optus modem to LAN port of the Netgear modem. It may be for Voice on the Optus version and why it is a different colour but Blue is not listed as a colour in the user guide.
