5GHz WiFi versus 2.4GHz? Is it worth it?
I have recently upgraded my broadband from 10 Mbps to 30 Mbps with Virgin Media. I know that I am getting the full 30 Mbps as it has been verified by Sam Knows. My problem being that I struggle to get much above 20 Mbps over a wireelss connection. They sent me a Super Hub for the increased speed, although why they see this as necessary I'm not really sure as my previous router, a D-Link DIR-615 has the same wireless speed and rating as the Super Hub. The ethernet ports can handle 3x greater speeds than the D-Link, but the LAN isn't the issue here.
I can get the full 30 Mbps when connected via ethernet, but can't get anywhere near that with the wireless. I have gone through all 13 wireless channels and found the one that seems to work best, but I can't seem to get anywhere over 25 Mbps. That's not a reliable 25 Mbps either, it drops to just over 20 at times... I don't really understand why there is this discrepancy when the wireless adapter claims to be connecting to the router at 216 Mbps (at the moment), so should be more than enough to handle a 30 Mbps internet connection... I know it's the wireless that's restricting the speed as I get the full speed over ethernet, but what can I do to get the full 30 Mbps over the wireless network?
One thing I did notice was that the Super Hub is a dual band router, so I could change it to a 5 GHz frequency rather than the default 2.4 GHz. I would have to buy a new wireless adapter, which I can get for £32.64 on Amazon (Netgear WNDA3100v2), which I don't mind doing, but will it actually make much of a difference? I am currently using a Netgear WN111v2 which only operates at 2.4 GHz.
Does anyone have any other suggestions as to what I could do to improve my wireless speed and reliability? Has anyone done a comparison of 2.4 GHz versus 5 GHs?
Thanks in advance for any advice/input.
