Troubleshooting Corporate WiFi Connectivity: Internet Access Issue

B.

Based on the given scenario, Ann can only access local pages while connected to the corporate WiFi. This implies that her internet traffic is being restricted by some network settings or policies.

Out of the given options, the action that would MOST likely fix the problem is option B - Configure the browser proxy settings.

A proxy server acts as an intermediary between the user's device and the internet. It can be used to control and monitor internet traffic by enforcing policies such as filtering or blocking certain websites, limiting bandwidth usage, and more.

In this case, it's possible that the corporate network has a proxy server configured to restrict access to external websites. By configuring the browser's proxy settings, Ann can route her internet traffic through the proxy server, allowing her to access external websites.

The other options are less likely to solve the problem. Renewing the IP address (option A) can help in some cases where the device is not getting a valid IP address from the network, but it's unlikely to be the root cause of the problem in this scenario.

Clearing the browser cache (option C) or disabling the pop-up blocker (option D) may help in some cases where the browser is misbehaving, but they are unlikely to address the underlying network restriction that is preventing access to external websites.

Therefore, the best course of action to fix the problem is to configure the browser proxy settings (option B) to allow access to external websites.
