Hi folks, so you get that brand new phone or tablet and are wondering why you aren’t getting N speeds? Well that might be because your manufacturer cheaper out and only put in a wireless card that supports 2.4 GHZ N only.
You see most new devices only support the 2.4 GHZ wireless range and not the 5 GHZ range. Whereas N can actually be made available in both ranges. A lot of wireless installations only support N in the 5 GHZ range which then means that your device ends up connecting at non N speeds if it only supports 2.4 GHZ.
What can you do to fix this? Not much. If it’s your own network, you can make sure your solution support N on both ranges. But if it’s not you out of luck unless you opt to buy a different smart phone or tablet that supports A/B/G/N instead of just B/G/N.
