Before I had 25/5 service and the N standard router did just fine. Now it doesn't do the job. Online speedtest reads at 82 so I have the line. But my laptop is getting less than 30 in my room. My laptop has the following WiFi card: http://www.intel.com/content/www/us/en/wireless-products/centrino-advanced-n-6205.html
What is this talk about 2.4 and 5GHz? Can my laptop be connected at once over both bands? And would that let me use the full 70Mb over Wi-Fi?
