You could take some virtual courses in basic networking before you start. Seriously, 9/10 times all works out of the box. But if there is a need to configure a network you really need knowledge to get that done. Just comapre it with driving a car; anyone can do that, but fixing or tuning it is a totally different matter.
You do not need a reset by definition after a disconnect. That depends merely on the modem used.
You should also be aware that a forum like this exists practically only of issues and does not represent the avarage opinion about the product. You will notice that every brand has a forum in which people present their issues.
