Good-Night,

I'm currently having a problem with my laptop; for some reason it doesn't connect to the 5ghz band automatically, despite changing the driver settings to prefer the 5ghz band. I've noticed, only when I scan for networks, it finds the 5ghz band and connects. What could be causing this problem? Is there a windows setting or any for that matter that's prohibiting the laptop from connecting to the 5ghz band? The roam tendency and roam decision are set to auto. I have association roam preference set to enabled and band preference set to 802.11a. The wireless card is a Broadcom BCM43228. The wireless AP is a Ruckus ZoneFlex 7351.

Instead of using 802.11a on the wireless card, switch it to 802.11n

802.11a is pretty much a obsolete standard.

Unfortunately, there's no option for that. So, I guess the 802.11a is for the 5ghz band and the other option 802.11 b/g is for 2.4ghz. I do have a another question though. Would the 5 ghz band be better than the 2.4 ghz band, in terms of throughput, even with slightly lower link rates?

The 802.11 Standard is where you get the bandwidth. Here is a comparison chart; https://www.att.com/support_static_files/KB/KB3895.html

Now talking about the 2.4, and 5 Ghz bands, these are the radio frequencies of the wireless devices. The 2.4 Ghz band is prone to more interference from most devices that emit a radio frequency. These would be microwave oven, cordless phones, cell phones to name a few.

The 5Ghz band is more restricted, as to what can transmit within that band, So you would get less interference.

For your laptop, you can pick up a USB wireless dongle, which will take advantage of your routers 802.11n standard.

Hmm, not the exact answer I was looking for. I'll just look in the router settings for the throughput estimate and choose. The laptop is sticking to the 5ghz band now although I did change the roam tendency to aggressive and the roaming decision to optimize bandwidth. I guess it switching between bands had something to do with the channelfly feature. The laptop's card is currently using 802.11n. I think I should have stated the card was dual band N instead of listing the model number. Thanks for the information you supplied!

Go into the Advanced settings of your wireless card, you may be able to set the wireless band preference.

Open the Network and Sharing Center > Change Adapter Settings > right click on your wireless card, select Properties > click on Configure > Advanced.

You will have options to adjust the parameters of the wireless card.
