I have a Netgear Wireless-N 300 router. I have a Arris Tg862g. Normally my router would receive an internet signal through my modem. That way I could have multiple devices connected to the internet and I could host servers. Then, someone unplugged my router and reset the modem and router. Now, whenever I connect my router it won't get internet access. I had a friend setup everything for me, so I don't know how to resolve this issue.
