CompTIA Network+ questions
- 1.You work as a network administrator. Your network is medium-sized and consists of a mixture of different platform computers. The network is split into multiple subnets located across a large geographical area. IEEE 802.11g Wireless Access Points are found in more than half of the subnets. You receive reports that one of the subnets has experienced a lot of downtime. You are sent to the branch office with the problematic network to conduct on-site troubleshooting. You soon notice that the downtime only affects wireless users and the downtime lasts approximately an hour around midday every day. Which of the following would be an appropriate action to address this problem?
