Several WIFI users are reporting the inability to connect to the network. WLAN users on the guest network are able to access all network resources without any performance issues. The following table summarizes the findings after a site survey of the area in question:
Which of the following should a wireless technician do NEXT to troubleshoot this issue?
The primary issue appears to be channel overlap among the access points (APs). Overlapping channels can cause interference and degradation of network performance, which would explain the connectivity issues being experienced by the users. AP1 and AP2 are on channels 2 and 1, respectively, which are too close and could lead to interference. A more appropriate channel setup would be non-overlapping channels such as 1, 6, and 11. Therefore, reconfiguring the channels to reduce overlap is the most effective next step to troubleshoot this issue.
Still tryna figure out why you'd want the Guest users to access all resources on the network...
That bit was confusing me as well. Thought it was a trick question.
That's because normal people do not apply for the job of "certification question creator". These are just random texts and when we ignore something we are punished.
Received Signal Strength Indication (RSSI) is a measurement of the strength of a received radio signal. It is measured as a negative number on a logarithmic scale, which means that the closer to 0 the RSSI is, the better the signal. Clearly, AP 1 and AP 2 has channel/frequency overlap that causes the RF signals to interfere with each other. Thus, the correct answer is A. Answer B is incorrect because by using directional antennas, the RF signal will be directed toward a single direction. Directional antennas are commonly used for long-range fixed wireless, but since you would presumably want to cover an area with enough signal so users can connect, this answer is out of the question. Answer C is incorrect because the SSID of a wireless network allows clients to connect, but it is not directly related to performance issues. Answer D is incorrect because that would increase attenuation and decrease the radiated signal of APs 3 and 4 (causing performance drop in the guest network) without addressing the low received signal strength from APs 1 and 2.
A. Reconfigure the channels to reduce overlap should be the NEXT step a wireless technician should take to troubleshoot this issue. Based on the site survey findings, it appears that AP3 and AP4 are operating on channels 5 and 11, respectively, which could be causing interference with AP1 and AP2, both of which are on channels 2 and 1, respectively. In addition, the RSSI for AP3 and AP4 is much stronger than for AP1 and AP2, which suggests that clients may be associating with AP3 and AP4 instead of AP1 and AP2. To address this issue, the wireless technician should reconfigure the channels on the APs to reduce overlap and interference. This may involve changing the channel assignments for AP1 and AP2 to channels with less interference, such as 3 or 4. Additionally, decreasing the transmit power on AP3 and AP4 may also help to reduce interference and encourage clients to connect to AP1 and AP2 instead.
Replacing the omni antennas with directional antennas or updating the SSIDs on all the APs are not likely to resolve the issue of clients being unable to connect to the network. These steps may improve performance, but they are not directly related to the issue of clients being unable to connect.
The guest users are on the non-overlapping connection while the corporate are within the overlapping AP.
What waqdhiyo means is that the channels have to be distanced by at least 5 (1, 6, 11) for example. The channels are overlapping and causing interference.
What does inability to connect to WiFi , has to do with Chanel overlap.
Its gotta be D. There are 3 APs so you WILL have some overlap, theres only 3 non overlapping channels. The AP1 and AP2 wifi have VERY low power -80s. They need directional antenna to get a much better signal, like the Guest networks have.
Sorry meant to say its gotta be B. Directional Antenna
AP1 and AP3 makes for some nice overlaps
Looking at the question again I realized I made some errors in making this statement. Only because I think of the correct way channels are set up I didn't notice the 5 lol. Ap1: 2 Ap2: 1 Ap3: 5 AP4: 11 You want separation between the channels otherwise it does cause overlap. 1 2 . . 5 . . . . . 11 This gives you an idea of the overlap. A healthy example: 1 . . . . 6 . . . . 11 To avoid the overlap they need to be separated at least by 5 channels
So channell should be 1,6,11,11?
chapgpt told me 1,6,11,3
A is the correct choice To get all questions, contact me <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f7839f9296d9849a9e839fc5c7b79882839b98989cd994989a">[email protected]</a>
May be helpful: overlapping can reduce the Received Signal Strength Indicator (RSSI) of a wireless signal. When multiple wireless networks operate on channels that overlap, the signals can interfere with each other, resulting in a weaker signal strength and reduced RSSI for each network.
its soemthing to do with overlapping so I guess its A
Adding Channel 2 to access point one causes Channel overlap. Especially given the other access points are 1, 6 and 11
