Windows 7: USB WiFi speed half that of wired

USB WiFi speed half that of wired

I am a complete noob re WiFi (alway use hard wired) but recently bought a cheap USB dongle described as 150Mbps 11n. On testing I found I was getting about 22Mbps download with the dongle (1 metre from router) compared to 62Mbps wired. Upload speed was about the same as wired.

A bit of Googling told me this was a simplex/duplex problem. I did a test with a friends laptop and got full speed, so its not my router (BT homehub) and I have the latest driver from Windows update. So - is this about par for a four quid WiFi dongle, or do I need to set some value or other to get duplex? I could see this half speed business being a problem for someone already on a low speed line.

Hi 3D Jed.

Could I have more details on the USB Dongle please?

Also is it a 3.0 USB? Maybe you friend has usb 3 and you only have usb 2?

The dongle is connected to USB 2. The test with friend's laptop was using the LT built in WiFi, and down speed was about 55 Mbps ie full speed, which I guess shows the router is capable of full speed. The dongle box says 802.11n 150 Mbps - this one from Amazon in UK

Like I said, I'm a WiFi noob who uses wired normally, but I also build computers for friends etc, and nowadays they often ask 'Is it wireless ?' - hence my interest in USB dongles.

edit : just remembered I have USB3 on back of box. Tested on that socket, but same speed.

Ya if you see you can get up to speeds of 150 but here what it says
Quote:
Data Rate: 6,9,12,18,24,36,48,54,108,150Mbps
I have one here which was just a cheap one like your's which doesn't get the full speed either if your looking to get the full speed you will need a better one. A lot of people get fooled by it including myself There's ones you can get for about 20 and above. I paid €12 for mine and it's not great.

Hope this helps you

Just checked the router and its 802.11n. I think benji206 has the answer - its a cheap model. Not bad for 4 quid I s'pose.

The D-Link DWA-130 will give you the full 300Mbps for practically nothing. The 802.11n Only setting and using channel bonding "20-40Mhz" setting might get you more from your current wireless NIC.
Amazon.com: dwa-130

But I like the one I'm using now the best.

If a quid is one pound, that is only $6.12 and is a little cheap.
