Hi,
Thank you for posting the question on Microsoft Community forums. As per the description, you need help in managing the wireless networks.
If you need to change or delete a wireless connection profile, you can usually do it by right-clicking the network in the network list and choosing a command on the menu that appears.
Refer:
Manage wireless network profiles
http://windows.microsoft.com/en-US/windows-8/manage-wireless-network-profiles
When you connect to a new Wi‑Fi network, it’s added to the list, and
Windows will connect to that network while it’s in range. If you connect to another Wi‑Fi network while in range of the first network,
Windows will prefer the second network over the first one.
To delete a profile, you’ll need to open the list of available networks. Locate the network name on the list and right-click or press and hold on it. Click or tap “Forget this network" to delete the profile from your computer.
Hope this information helps. Please reply with the status so that we could help you further.
