The Lenovo IdeaCentre A540-24 All-In-One system has both ethernet cable as well as 5G, 802.11AC WiFi connectivity. If you are connecting the IdeaCentre A540-24 AIO via an ethernet cable to your internet service, be sure the cable you are using and the connectors are not damaged. If there is nothing wrong with your ethernet cable and you have a wireless router, try connecting the IdeaCentre A540-24 via WiFi. Also be sure you have the latest version of Windows 10 on the computer, then update all of the BIOS files and drivers up to that latest version of Windows 10. You can easily accomplish this by scanning the computer with the Lenovo Utility software installed on the computer. This system has Lenovo utilities installed to help maintain the health of the device and keep the operating system software up to date. Type "Lenovo Vantage" in the Cortana Search window (if Lenovo Vantage is not installed on your device, you can download the APP and install it now). Select Lenovo Vantage from the list. In the window that opens, click on "Health and Support". In the expanded menu, select "Hardware Scan" In the window that opens, select "Run Quick Tests". This will scan your entire system for errors. Follow any directions that may pop up. If the problem continues after this scan, now click on "System Update". First select Windows update from the menu. Scan your system to be sure you have the latest version of Windows 10. Once that scan is complete, select "Additional Updates". This will scan your device to be sure there are no new BIOS/Driver updates needed. Follow any instructions that may pop up. If the issue still continues after these updates, we recommend you call Lenovo Tech Support at: 877-453-6686 for additional help.
