A user reports that their wireless connection is slow. The technician knows that the access point in use is an 802.11g. Which of the following could be the cause of the user's issue? (Select TWO).

The correct answer is A. User is too far from an access point D. User is using an 802.11b card. Two factors can slow down an 802.11g connection: (A) Distance from the access point - as a user moves farther away, signal strength degrades, causing the connection to fall back to lower data rates (802.11g scales down from 54 Mbps to as low as 1 Mbps). (D) Using an 802.11b NIC…

Explanation

Two factors can slow down an 802.11g connection: (A) Distance from the access point - as a user moves farther away, signal strength degrades, causing the connection to fall back to lower data rates (802.11g scales down from 54 Mbps to as low as 1 Mbps). (D) Using an 802.11b NIC - 802.11b is backward compatible with 802.11g, but 802.11b only supports up to 11 Mbps. When an 802.11b device connects to an 802.11g AP, the entire cell may slow down because the AP must use protection mechanisms to accommodate the slower device. A refrigerator does not emit 2.4 GHz RF interference significant enough to cause this (microwave ovens are the common culprit). Insufficient RAM affects general PC performance, not wireless throughput. If the AP were powered off, there would be no connection at all.
