Android Question

I just purchased a new lepan tc1010 quad core tablet from shopnbc and having trouble getting certain apps or picking up WiFi as well as when at home if I'm traveling. Is there anyway to root this or be able to work online with it better when traveling? For instance, I was at my sister's and put in her WiFi password but it was running way slow on youtube and internet browser. Please help me get the most out of my tablet purchase.
