A user's wireless laptop stopped working. A technician replaced the wireless card, but the wireless range is now limited. Which of the following should the technician perform NEXT?
A.
Verify the antenna's connection.
B.
Switch from a 2.4GHz band to a 5GHz band.
C.
Change the channels of the Wi-Fi card settings.
A
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.
A. Verify the antenna's connection.
Here's why:
Limited wireless range often points to a problem with signal strength. A loose or damaged antenna connection can significantly weaken the signal, resulting in a shorter range.
Here's why the other options are less likely:
B. Switch from a 2.4GHz band to a 5GHz band: While 5GHz generally offers faster speeds, it often has a shorter range than 2.4GHz. Switching to 5GHz might worsen the range issue.
C. Change the channels of the Wi-Fi card settings: Changing channels can help improve signal strength if there's interference from other devices on the same channel. However, if the primary issue is a weak antenna connection, changing channels won't resolve the problem.
D. Upgrade the wireless driver: An outdated driver could potentially cause various issues, including poor performance. However, it's less likely to be the primary cause of a sudden drop in wireless range after replacing the wireless card.
If the wireless range is limited after replacing the wireless card, it is likely that the antenna connection was not properly reconnected or is loose. Wireless cards rely on attached antennas to send and receive signals effectively. Without a proper antenna connection, the wireless range will be significantly reduced.
The most likely cause of the limited wireless range is a A. Verify the antenna's connection.
When replacing a wireless card, it's crucial to ensure that the antennas are properly connected. A loose or damaged antenna can significantly reduce the wireless range.
Here's why the other options are less likely:
B. Switch from a 2.4GHz band to a 5GHz band: While the 5GHz band can offer better speeds, it generally has a shorter range than the 2.4GHz band. Switching bands might not improve the range in this case.
C. Change the channels of the Wi-Fi card settings: Changing channels can help reduce interference, but it won't necessarily improve the range.
D. Upgrade the wireless driver: An outdated driver can cause various Wi-Fi issues, but it's less likely to be the root cause of a significant range reduction.
By checking the antenna connections, the technician can quickly identify and resolve the issue, restoring the laptop's wireless range.

It has to be A. The reason for this is that if you don't ensure connecting the antenna (usually on shape of 2 wires) to the wireless card, the connection is going to be very limited.
If you have ever disassembled and reassembled your laptop without touching the display, you'll know for sure you've seen the wi-fi card somewhere on the motherboard. The wi-fi antenna, however, is only located inside the display frame of the laptop. The question did not mention anything about touching the antenna. D should be more reasonable as an answer.
how the antenna connection will affect the wireless card? Is it not option D?
