Exam N10-007 topic 1 question 750 discussion

Option B. An incorrect channel assignment is on the nearest APs is not the most likely cause of the issue. Incorrect channel assignment could cause interference and degrade the performance of a wireless connection, but it would not typically cause devices to connect to a far AP instead of the nearest ones. The devices' decision on which AP to connect to is usually based on the signal strength, which is determined by the power level of the APs and their distance from the device. If the power level of the far AP is set too high, it might have a stronger signal than the nearer APs, causing devices to connect to it instead.

devices will typically connect to the access point (AP) with the strongest signal. Therefore, option C is the most likely cause of the issue described. The power level of the AP on the far side of the warehouse may be higher than the nearest APs, making it the loudest and most easily reachable for the handheld devices.

this question is on 008 and they said the ans is power level

Overlapping channels cause your signal-to-noise ratio to drop, causing severe signal loss from interference. Power levels are more of a security issue; if the AP was farther away, its signal would be weaker anyways. So, since the devices connect to the far AP, that means that near APs have a really weak signal from interference.

The answer makes sense. If the closer AP is on the wrong channel, overlapping with another close AP, it will make the signal worse, which in turn, makes your device connect to a clear and working signal.

Answer is wrong. Clients usually choose WAPs based on RSSI, or “Received Signal Strength Indicator,” a measurement of how well your device can hear a signal from an access point or router. Power levels would definitely affect that.

There's something going on about channel overlap. I think.

When its signal power is higher than closer AP, the device will connect to the far AP automatically.

Can anyone explain? Assume all near APs have the same channel. Is that going to stop me from connecting to them? If an AP on the other side of the building has its power cranked up higher then the closer APs my device might want to connect to it.
