Had a tech from dell try from device manager with no luck, they wanted to send me to the paying department , have credit card so no go. If anybody culd help me that would be greatly appreciated it is a Dell inspirion 15-3552 Thank you
If your WiFi card supports 802.11ac, it automatically supports 5 GHz since that is required by the 802.11ac spec. If it only supports 802.11n, then it may or may not support 5 GHz. In that case, open Device Manager, expand the Network Adapters category, and look for the name of your WiFi adapter. Post it here and we can tell you whether it supports 5 GHz, or if you just Google the name of that adapter yourself, you might find a page listing the specs of that card that will tell you whether it supports 5 GHz.
Can you let me know the model of wireless card the system is using, and what wireless router/device you're trying to connect to?
