Wireless users are reporting intermittent internet connectivity.
Connectivity is restored when the users disconnect and reconnect, utilizing the web authentication process each time.
The network administrator can see the devices connected to the APs at all times.

A. B. C. D.A.
In this scenario, wireless users are experiencing intermittent internet connectivity, which is restored when they disconnect and reconnect and go through the web authentication process. The network administrator can see the devices connected to the access points (APs) at all times.
To determine the cause of the issue, the network administrator should follow the troubleshooting steps outlined below:
A. Verify the session time-out configuration on the captive portal settings: One possible cause of the issue is the session time-out configuration on the captive portal settings. If the session time-out is set too low, wireless users may experience intermittent connectivity. In this case, the network administrator should verify the session time-out configuration on the captive portal settings and adjust it as necessary.
B. Check for encryption protocol mismatch on the client's wireless settings: Another possible cause of the issue is an encryption protocol mismatch on the client's wireless settings. If the client's device is set to use a different encryption protocol than the AP, the device may experience intermittent connectivity. In this case, the network administrator should check for encryption protocol mismatches on the client's wireless settings and adjust them as necessary.
C. Confirm that a valid passphrase is being used during the web authentication: A third possible cause of the issue is an incorrect passphrase being used during the web authentication process. If the passphrase is incorrect, the device may not be able to connect to the wireless network. In this case, the network administrator should confirm that a valid passphrase is being used during the web authentication process.
D. Investigate for a client's disassociation caused by an evil twin AP: A fourth possible cause of the issue is a client's disassociation caused by an evil twin AP. An evil twin AP is a rogue AP that mimics a legitimate AP, causing clients to connect to it instead of the legitimate AP. In this case, the network administrator should investigate for a client's disassociation caused by an evil twin AP and take appropriate measures to prevent it.
Of the options listed, verifying the session time-out configuration on the captive portal settings (Option A) is the least likely to determine the cause of the issue. This is because the symptoms described do not necessarily point to a session time-out issue. Therefore, the best option would be to check for encryption protocol mismatches on the client's wireless settings (Option B), followed by confirming that a valid passphrase is being used during the web authentication process (Option C). If neither of these options resolves the issue, the network administrator should investigate for a client's disassociation caused by an evil twin AP (Option D).
