Which wireless frequency Windows 7 considers the best? 2.4Ghz / 5Ghz?

Hello Windows Gurus,

I'm starting to design a 5GHz Wireless Networks that will work together with an 2.4Ghz during the tests and transition phase. In order to keep the same configuration into the clients, we are choosing the same SSID, so we do not have to go one be one and change the machine configuration.

My question is, If there are two WLAN, one with 2.4Ghz and another with 5Ghz with the same SSID, how Windows will choose to which frequency to connect?! To the 2.4Ghz (the default frequency for most APs) or will it try to connect to the 5Ghz (Faster and Less Interference)?!

I also checked and the computers does have Wireless card that works with 5Ghz frequency.

Welcome to Seven Forums,

When you said two WLAN, are there 2 WAPs? One operates at 2.4GHz and another one at 5GHz? Perhaps, you're talking about a Dual Band Router that supports both Standards (11n and 11b/g)?

If your Wi-Fi adapters support both and they are configured with a mixed mode then they should be able to connect to the 5GHz band. The wireless mode can also be changed from your router and set it to just '5GHz' if you'd like all the wireless network devices to utilize the 5GHz.
FYI....802.11n supports both 2.4 and 5GHz clients but you must consider 5GHz than the 2.4GHz if you'd like to achieve a great network performance.
