I have an old ADSL WLAN router (Allied Telesyn AT-ARW256E) which I used previously when I was using ADSL Internet Connection.

However lately I shifted to 3G/HSDPA Mobile Broadband Internet, and connect my Win XP Desktop PC directly with a USB HSDPA Modem. I want to share this 3G Internet Connection from my Desktop with my Notebook and VoIP gateway using Windows ICS.

Is there any way I can re-use my old ADSL WLAN router to share Internet, both via ethernet ports and WLAN?

So far I can't make it work, however when I use a LAN switch instead of ADSL WLAN router, I can share Internet.

Please help me to tell how I can re-use my ADSL WLAN router as I want to access Internet on other devices not only using ethernet ports but also via WLAN.

Thanks a lot !
