Although probably not as much as my poor knowledge of computers. Long story short: Have ACER TravelMate 507DX. Bad hotel connection fried internal modem. Computer guy friend disabled internal and fitted with a DLink modem card. Modem card works 3 minutes, then rests for 3 minutes. Have not tried support from D-Link site, but if there's a quick fix or answer, would just as soon try to resolve this myself and not bother with lengthy problem-solving. So, any quick answers or quick fixes? <img src="/images/graemlins/confused.gif" alt="" />
