We have a Linsky Wireless-G

Question

We have a Linsky Wireless-G router. We have high speed internet from Charter and two days ago I called Charter toreset the modem because we had no internet. Since then, mydaughter does not have wireless and I have tried the CD that came with the purchase of the router, but no luck. Both of us have Dell laptops and my daughter needs the internet in her endeavor to obtain a Nursing degree. I have tried the CD at least 7 times.I need help,Archie McDaniel
