A network administrator is troubleshooting severe signal degradation and frequent disconnections reported by users working near large metal shelving units in a warehouse environment. A site survey reveals high signal attenuation and co-channel interference on the 2.4 GHz band. Which TWO of the following troubleshooting steps should the administrator perform to resolve these wireless connectivity issues?
- Migrate the access points in the affected area to non-overlapping channels (such as channels 1, 6, or 11).Answer
- Relocate access points or install directional antennas to direct signal coverage down the aisles and clear of metal obstructions.Answer
- CForce the switch interface speed and duplex settings connected to the access point into half-duplex mode.
- DReconfigure wireless client devices to use APIPA self-assigned IP addresses when signal strength drops.
Answer
The administrator should migrate access points to non-overlapping channels (1, 6, or 11) and relocate access points or install directional antennas to bypass metal obstructions.
Migrating access points to non-overlapping channels (1, 6, and 11 on the 2.4 GHz spectrum) eliminates channel overlap and adjacent-channel interference. Relocating access points or deploying directional antennas bypasses physical attenuation and signal reflection caused by heavy metal structures in the warehouse.
