Every laptop on the office Wi-Fi is slow. A wired PC on the same switch is fast, and a wireless survey shows the channel packed with neighboring networks. Which cause fits?
Select an answer to reveal the explanation.
Short Explanation
The wired desks are fine, and the air around the access point is crowded with other networks. You are looking at a congested wireless channel. A name failure, a stuck sheet, and a clock battery would not spare the wired PCs and pile only onto the radio.
Full Explanation
Wired PCs on the same switch are fast, so the office LAN and the internet path behind it are not the bottleneck. The laptops are slow and the survey shows a channel full of neighbors, which is wireless congestion. DNS would slow name lookups for wired PCs too, not only the laptops. A paper jam is a printer fault. It does not fill a radio channel. A CMOS battery keeps the firmware clock. It does not create neighboring networks. Exam caveat: moving to a clearer channel, or to another band the clients support, is the usual relief. Replacing the access point does not help if the new one sits on the same crowded channel. Operational check: survey again, move the access point to a less used channel, and compare laptop throughput with the wired PC. Write the result on the ticket before you close it.
