New laptop - dongle can't connect

  CarlyW 22:28 15 Dec 2009

Hiya, I hope someone can help me out. I've got a new Acer Aspire 5738Z with Windows 7 and I can't connect to the internet with my 3 dongle. The dongle has installed correctly but just can't connect.

I've tried turning off the firewall (Norton 360) incase that was blocking it but that made no difference.

I know the dongle's fine as I'm using it in on my old laptop to post on this forum, which is a bit annoying because I'm sitting next to a nice shiny laptop I'd much rather be using!

If anyone has any ideas that might help that would be great.

Are you trying to connect using a USB Wireless Adapter Dongle on your new laptop?

All present day laptop have a wireless card build in to the laptop and do not need a USB

Wireless Adapter Dongle unless the build in wireless card is bad

Remove the USB Wireless Adapter Dongle and check that the “Wireless Radio Antenna” is

switch on via a small slide switch on the laptop or using the FN (Function) key you have to hold

down the FN key and press the key with a small antenna icon to turn on the “Wireless Card


You now have to check that the wireless card is “Enable” from within the Network Connection


Start – Setting - Network Connection - Right click-“Wireless Area Connection”- Enable

or Disable as required

If already “Enable” try “Disabling” and re “Enabling” the wireless card

It is nothing to do with the wireless card, CarlyW is using a 3Dongle which is a USB Modem.
Are you sure the software has installed correctly?
Are you getting an indicaton that the modem has been detected by the system?
Try connecting by clicking on the netwrok icon and selecting 3USB rather than use Mobile Partner.
