Pictures won't transfer, wireless mouse won't work, router won't work - computer is 6 weeks old

My new laptop is full of "issues".  It is 6 weeks old and the previously working Logitec wireless mouse stopped working.  A new D-Link router won't work for more than 10 minutes and then I'm disconnected and the network disappears.  I spent over two hours with the tech support in India and she downloaded drivers and did her best - to no avail.  Finally she restored the laptop to factory settings.  The mouse still doesn't work (and it works in other laptops), the router still doesn't work, and now my pictures won't transfer from the memory card.  What is going on?  Can someone help me?  I'm distraught and receiving no reply from Dell.  Thanks.
