I need your help here, I have just bought a somaport 300 wireless modem/router from my service provider, but I can't seem to get my computer to recognise the unit once i try connecting it via the ethernet cable, but it seems to work fine with the USB cable but the connection is rather slow. I on the other hand got it to work on my other fujitsu laptop, is there any configuration that needs to be done??
