I have to guess you've read http://www.wikihow.com/Use-Your-Mobile-Broadband-Connection-Card-for-Your-Wireless-Router and other posts.
Did you consider a router would be a better choice?
I have currently the following connection:
A Seimens Gigaset SE568 Wireless Router connected to a DSL Line and broadcasting a WIFI signal throughout my house. I receive this WIFI internet connection on my laptops using their respective WIFI adapters, and on my desktop using a GASKY GS-28USB Wireless USB Adapter, and use this internet connection simultaneously in both desktops and laptops.
Now, I am shifing to a new 3G USB Mobile Broadband service:
Where I can directly connect the 3G USB Mobile Broadband Stick to my desktop or my laptop and use the internet directly, but not all at once through my router as was previously configured.
Is there a way using the existing hardware, can I configure my desktop to share this internet connection and broadcast from the GASKY GS-28USB Wireless Lan Card to the Seimens Gigaset SE568 router and then throughout my house for simultaneous access, or directly share the internet through the GASKY adapter itself, or is there some other configuration I can use ? Please give me a detailed description of setting it up if possible.
My Desktop has Windows 7 installed as an operating system.
Thanks in advance.
