Zorluk: ZorWired and Wireless Network Issues

During an infrastructure audit at a regional clinic, a technician is assigned to resolve two independent connectivity problems. First, laptop computers frequently drop Wi-Fi signal when migrating between coverage zones in the 2.4 GHz band. Second, a newly connected wired workstation fails to communicate across the local subnet and displays an auto-configured IPv4 address of 169.254.88.15169.254.88.15. Which TWO troubleshooting actions should the technician implement?

  1. Reconfigure wireless access points to use non-overlapping 2.4 GHz channels 1, 6, and 11.Cevap
  2. Inspect physical network interface link lights and verify connectivity to the local DHCP server.Cevap
  3. C
    Assign adjacent channels 2, 3, and 4 across neighbor access points to maximize channel density.
  4. D
    Modify the primary DNS server scope settings to lease valid IPv4 addresses to the subnet.

Cevap

The technician should reconfigure wireless access points to use non-overlapping 2.4 GHz channels 1, 6, and 11, and inspect physical network interface link lights while verifying connectivity to the local DHCP server.
Reconfiguring 2.4 GHz wireless access points to non-overlapping channels (1, 6, and 11) eliminates co-channel interference and restores stable wireless coverage. Inspecting physical link lights and verifying DHCP server access correctly addresses the root causes of APIPA automatic address assignment on the wired client.

Adım Adım Çözüm

1
Address wireless signal degradation and roaming drops in the 2.4 GHz band.
Identify co-channel interference caused by improper channel assignment.
The 2.4 GHz band has only three non-overlapping channels: 1, 6, and 11. All other channel choices result in adjacent channel interference.
2
Address the wired workstation's APIPA address (169.254.88.15169.254.88.15).
Confirm an inability to communicate with a DHCP server for IP address assignment.
Troubleshooting APIPA requires confirming physical Layer 1 connectivity (link lights) and verifying DHCP server reachability.
