How Can I Identify a Dual Band WiFi Card?
Asked by

I'm trying to figure out how to determine whether a WiFi card is dual band, specifically one that supports both 2.4 GHz and 5 GHz. Can anyone clarify what terms or specifications I should look for in the card's description? Also, does the Dell Wireless WiFi Card Link 802.11 a/g/n + Bluetooth 4.0 FXP0D DW170 qualify as dual band?
Answers
Dual band WiFi means it should support both the 2.4 GHz and 5 GHz frequency bands. If you can't find the term 'dual band' in the specifications, chances are it may not support both frequencies.

To check if a WiFi card is dual band, look for the standard numbers after '802.11'. For instance, the 802.11n standard can operate on both bands, while 802.11a and 802.11g operate on their own respective bands. In the case of your card, it supports 802.11a/g/n, which means it should work on both bands!

You can also find the specs online. For example, here’s a breakdown:
- 802.11a: 5 GHz only
- 802.11g: 2.4 GHz only
- 802.11n: both bands
So, a card that lists a mix like 802.11a/g/n is indeed dual band. Just make sure your router supports one of the standards mentioned.
