Cable Wifi speeds and power pack used...

Hey there...bit of information here to share.

 

Obviously there are other issues which can impact Wifi performance dependent on local environment variables which I won't delve into here, but always good to eliminate as many issues as possible in optimising your connected home.

 

Telstra have done some investigations and noticed that a number of customer faults and concerns around the Netgear CG3100 WiFi speeds have been related to the wrong power plug pack being used for that modem.

 

Example:

  • One customer on Cable Ultimate was getting download speeds on WiFi of less than 1mbit whilst testing next to the modem but achieving 100mbit via Ethernet. 
  • Once the power supply plug pack was replaced for the correct one (supplied) the wireless speeds increased to 55mbit. Ethernet remained the same and to spec.

 

The DOCSIS 1 Netgear CGD24N and CG814WG model cable modems use a 1A rated plug pack.

The Cable Ultimate capable DOCSIS 3 Netgear CG3I00 uses a 2.5A rated plug pack.

 

The plug packs look similar and the connections are the same. The DOCSIS 3 modem may seem to work with the DOCSIS 1 power pack - but they do not work properly.

I wonder how often customers that had upgraded to the newer service left their old plug pack in place, more than a few times I'd imagine

Yes I am one of the dummys that got a new modem and left the old power pack plugged in.  I have had ongoin wireless problems since.  The packs look exactly the same. Doh
