I currently use a Netgear wireless router WGR614v10. On occasion I use my laptop (using the wireless connection) to connect my tv (with HDMI cables) to watch live broadcasts. Recently I have experienced constant "buffering" while watching these live broadcasts. Is this router getting old and not able to perform as it should? Using the wireless function on my laptop seems to work okay for normal web surfing and reading emails, just having issues with watching these live broadcasts. If a new(er) one is recommended, is there anything that I should be on the look out for?
