A limited wireless range after replacing the wireless card could indicate that the antenna is not properly connected to the card, or that the antenna is damaged or obstructed. According to the web search results, some possible steps to troubleshoot and verify the antenna’s connection are:

Open the laptop case and locate the wireless card and the antenna wires. Make sure that the wires are securely attached to the card’s connectors, and that they are not loose or broken12.

Check the position and orientation of the antenna. Make sure that it is not blocked by any metal objects, walls, or other sources of interference. Adjust the angle or location of the antenna if possible to improve the signal strength3.

Replace the antenna with a new one or a compatible one from another device. Test the wireless range and performance with the new antenna2.
