Sharing WiFi on a Notebook

Alright -

I've got an external WiFi adapter (via USB) for my laptop. I can connect to my downstairs wireless router from my room, but my sister, a few rooms over upstairs, cannot from hers. It's bound to be possible however I'm having trouble with it. I've tried just about everything - how do I receive internet from my wireless router downstairs via my external WiFi card, then share it and brodcast it with my notebook's internal WiFi card to my sister? I can create an Ad-Hoc connection, that works. The trouble is that when I enable sharing on my internal card (given selecting my external card in the dropdown menu below "share this connection"), it discontinues to take MY internet from the external card. I want to have internet through the external card, fully useable by me, then broadcast the same internet connection (given re-vamped through my computer) to another computer. Any help is greatly appreciated. Thanks,

It won't work that way. You need a second NIC to establish the ad-hoc connection to the other PC. A preferable solution would be to get a wireless range extender. and leave that running so that both upstairs PCs can connect independantly.

I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

Thanks - I'm tring to do without having to spend any more money though. Don't I have two NIC cards - one external, one internal? Thanks for the help.

That is correct you have two nics. Google would give you the ICS [internet connection sharing] docs.

In a nutshell you ad-hoc your internal wifi to your sister.
Then you enable ICS between the two wifi nics.
Understand your external wifi and sisters nic have to be in a different subnet than your connection to the router. So lets say your connection to the router is 192.168.0.x. Your wifi to sister needs to be 192.168.x.1 for you and .2 for her. x can be any number from 1 to 254.


Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

Sorry I misread the original question. Didn't register that your laptop had two wireless nics. Wanderer is correct. he knows his apples.
