I'm unable to access the shared network drive where I store all my project files. I'm getting an 'Access Denied' error, even though I was able to access it yesterday. My network connection seems fine

Verify the DNS server settings on your router and individual devices.

From a connected device (if possible), try pinging an IP address directly (e.g., ping 8.8.8.8) and then a domain name (e.g., ping google.com).

Check the status lights and battery levels of all UPS units powering network equipment.

Verify if the entire building or office area has power.

Attempt a controlled reboot of the primary network devices, starting with the modem/router.

Visually inspect the main router, switch, and firewall for any signs of power loss or error indicators.

Visit the ISP's website or social media for official status updates.

Call your internet service provider to inquire about any reported outages in your area.

If access points are several years old, consider replacing them with newer, more capable models that support modern Wi-Fi standards.

Ensure all Wi-Fi access points and routers have the latest firmware installed, as updates often fix bugs and improve performance.
