I have a new Acer laptop with a Broadcom network adapter and can connect to a 802.11b wireless router but I couldn't connect to the router at the village library which I think has 802.11g. How do I know for sure how to set my Broadcom network adapter so it can connect to an 802.11g signal. What settings should I look for. I checked my computer's device manager but couldn't get a model number for the Broadcom adapter. I have windows vista home premium 32bit on my Acer Extensa 5420-5038.
