I've recently switched a user's laptop from an ethernet connection to Wi-Fi, and now they can't access our network drives. We're operating on an older network setup with a domain where users have specific access to certain folders. Normally, the user would log in with their username and gain access with no problems. However, after moving the workstation and connecting via Wi-Fi instead of ethernet, they're experiencing issues. I suspect that they might be logging into an old local user profile that has the same username and password as their network account. I've tried logging in with DOMAINUser, but that didn't resolve the issue. We're using a Windows server for our setup, and I'm looking for guidance on how to troubleshoot this.

Most likely, there are some access control lists (ACLs) or firewall rules that are blocking access to the internal networks when you're connected via Wi-Fi. It might be worth digging into those to see what's preventing connection.
First, check if the Wi-Fi connection is linked to the main corporate network or if it's actually a guest Wi-Fi. If it's the latter, that could be your problem—guest networks typically have restricted access to internal resources.
Make sure that the new Wi-Fi connection is set to Domain in the network properties. Sometimes, Windows assigns a new Wi-Fi network as Public by default, which could limit access.
Honestly, this might need hands-on help from your local IT support. They can take a closer look at the network settings and troubleshoot more effectively than we can from here.
You should verify if the Wi-Fi is on a different subnet. If it is, check if that subnet has the necessary permissions to access the servers using the correct ports. It’s a crucial step in figuring out the block.
