The question really isn't about which router is best, a router from the well known brands such as NetGear, LinkSys and D-Link are quite reliable.
Sometimes it just comes down to how well your ISP serves you in terms of reliability of your broadband connection. People that have problems with NetGear router is usually an isolated problem, maybe due to outdated firmware, or if it's signal strength that's the issue then that really boils down to the kind of environment the router has to deal with.
Your router won't do much of the work in this case, the most data that is transferred is the cable which gives you the video feed.
