What is a potential issue when using the WLC to upgrade and deploy the latest firmware image to all APs?
- Users will not be able to use the WLAN.
- Only one of the two bands would work at a time.
- Old 802.11 standards may not be supported anymore.
- Usernames and passwords must be manually entered into the AP so that WLAN authentication continues during the upgrade.
Answers Explanation & Hints: When APs are performing a firmware upgrade, users will be disconnected from the WLAN and the internet until the upgrade finishes. The wireless router may need to reboot several times before normal network operations are restored.
