Topics discussed in this chapter are as follows: • “WiFi Troubleshooting” on page 18 • “Assessing WiFi performance throughout a site” on page 25 • “Managing jobs” on page 35 • “Troubleshooting Problems with Your WiFi Advisor” on page 41 December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 17 Chapter 3 Testing WiFi Troubleshooting WiFi Troubleshooting The single-ended troubleshooting test includes the following: • Quick, visually intuitive assessment of critical WiFi network factors reduces troubleshooting time • Spectral insight within the same tool allows identification and isolation of common, non-802.11 interferers • Expert recommendations helps minimize the time spent to effectively optimize the network and reduces likelihood of repeat calls The following procedure describes how to troubleshoot a single connection on a network.This test is typically run if the service is not working properly. To troubleshoot a single connection Bring the iPad and WiFi Advisor to the location experiencing problems. Open the app on the iPad. Select Single-Ended Troubleshooting. Choose which WiFi Advisor device to use for the test. If you have previously used a WiFi Advisor device with this iPad, it appears in the list of devices. If it does not appear, you may need to register the device with the iPad and pair to it. See “Connecting a WiFi Advisor for the first time” on page 12 and “Registering and unregistering devices” on page 12. Select a result tab at the top: BSSID, Channel, or Spectral. BSSID results The BSSID results provide quick visibility into the wireless networks active in the current environment in both the 2.4GHz and 5GHz WiFi bands. The BSSID results report the RSSI per channel. A sample result is shown in Figure 7. Page 18 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Chapter 3 Testing WiFi Troubleshooting Figure 7 BSSID results This provides a visual representation of overlap in the channels to help identify problem spots. The BSSID graph area shows each visible BSSID by channel and signal strength. This view is useful for understanding an existing Access Point’s channel configuration and signal strength or for determining which channel to select for a new AP to be placed within the environment. To toggle between 2.4GHz band and 5GHz band, touch the band toggle switch in the upper left of the graph. The BSSID List view in the right pane provides a listing of all detected BSSIDs along with their channel setting, current signal strength, and MAC address. To change the order of the list, tap 123 (sort by channel) or ABC (sort by name). To view more details of a particular BSSID, touch the desired BSSID. From the BSSID Details menu, touch Trend Graphs. Trend graphs show RSSI, Noise, and Channel Utilization over time for the selected BSSID. A sample graph is December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 19 Chapter 3 Testing WiFi Troubleshooting shown in Figure 8. Figure 8 Trend Graphs Channel view The Channel view, shown in Figure 9, shows utilization and noise per 802.11 channel in addition to co-channel or adjacent channel interferers. You can view the best channels per band, best channels per channel width, or overall channel score. This allows you to select the best channels available in the current environment. Page 20 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Chapter 3 Testing WiFi Troubleshooting Figure 9 Channel results The Utilization graph in the top pane shows the channel utilization for all channels in the selected band. Touching a bar within the graph highlights the bar for that channel (the blue bar will turn green) and the “BSSID List” changes to the Channel Summary which includes values associated with that particular channel. The Noise graph in the bottom pane displays the noise per channel. Touching the band toggle switch in the upper left of the graph toggles between 2.4GHz band and 5GHz band views. As in the BSSID view, the BSSID List view in the right pane provides a listing of all detected BSSIDs along with their channel setting, current signal strength, and MAC address. To change the order of the list, tap 123 (sort by channel) or ABC (sort by name). Touching a specific BSSID from the BSSID list configures the Utilization bar graph to the channel associated with that particular BSSID and the “BSSID List” changes to the Channel Details view in the right hand pane. Touching a specific bar in the Utilization graph also changes the BSSID List view to the Channel Details for that December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 21 Chapter 3 Testing WiFi Troubleshooting particular channel which includes the channel score, the channel utilization, noise, the BSSIDs resident in the channel, and the BSSIDs that are overlapping (adjacent to) that channel. Touching Best Channels in the top right area of the Utilization graph displays a table that identifies the current top 3 best channels based on channel width for the band being viewed. Touching anywhere on the screen closes the table. Spectral results The Spectral results, shown in Figure 10, provides a real-time spectral analyzer configurable by 802.11 band, channel, and channel width. It is helpful for finding signals that interfere with 802.11 networks by showing both 802.11 and non-802.11 RF signals within a given channel of interest. Figure 10 Page 22 Spectral results WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Chapter 3 Testing WiFi Troubleshooting The Spectral results screen has 3 main areas: • The spectral graph area, where the real-time spectral data is displayed • The controls area, where the user can configure the spectrum analyzer ranges and modes • The BSSID List / Channel information pane Navigating the Spectral result screen As in the BSSID and Channel views, the BSSID List view in the right pane provides a listing of all detected BSSIDs along with their channel setting, current signal strength, and MAC address. To change the order of the list, tap 123 (sort by channel) or ABC (sort by name). The BSSID list is not continuously updated while spectral data is being displayed and is therefore labeled as SNAPSHOT as it represents a list of BSSIDs gathered over a finite period of time prior to turning on the Spectral Analyzer. Touching a specific BSSID from the BSSID Snapshot List configures the Spectrum Analyzer to the channel(s) associated with the BSSID selected, and changes the BSSID Snapshot view in the right pane to the Channel Details for that particular channel which includes the channel score, the channel utilization, noise, the BSSIDs resident in the channel, and the BSSIDs that are overlapping (adjacent to) that channel. NOTE: This data is a snapshot. Live data may vary slightly. The Spectrum Analyzer controls, located across the top of the graph, consist of the following: Band toggle switch – selects 2.4GHz or 5GHz bands for analysis Channel bandwidth selector – selects the width of the spectrum analyzer: – 20MHz – 40Hz, or – 80MHz (5GHz band only) Channel up (+) or down (-) – touch to increment or decrement the 802.11 channel(s) being analyzed Max Hold – turns the Max Hold trace on the spectral graph on or off. When Max Hold is on, a blue line appears above the standard spectral line that represents the peak value (in dBm) seen at each frequency point. December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 23 Chapter 3 Testing WiFi Troubleshooting Clear – located under Max Hold, it resets the Max Hold trace and restarts the measurement. Average – allows averaging of the real-time trace when on Number of Samples – select the number of samples to be used for averaging of the real-time trace World view – shows all channels. Changing the channel bandwidth changes how channels are represented in the world view. To insert a vertical cursor within the real-time spectral plot, touch the graph where the cursor position is desired. The cursor readout box in the upper left reports the frequency at that position, in addition to the real-time and max hold signal levels at that frequency. The cursor can be moved by tapping anywhere on the graph within the channel width. By default, a cursor is located at the left edge of the view. Troubleshooting Spectral measurements The following are some common interferers that could show up in a spectral measurement. Microwave ovens can interfere with an 802.11 signal. They are most prevalent in channels 10 and 11. If possible, it is a good idea to look at the spectral response while the microwave is running to determine it’s impact. Bluetooth devices appear as spikes and appear to “roll” through the spectral view. They are fast moving and you may only see them occasionally. The systems are designed to be interoperable, but Bluetooth will impact throughput. Page 24 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Chapter 3 Testing Assessing WiFi performance throughout a site Channels can “bleed over” into adjacent channels. The width of the signal (due to RF considerations) can affect nearby channels, as shown in Figure 11. Figure 11 Spectral view of channel overlap Assessing WiFi performance throughout a site The general procedure for a Site Assessment test is: Place one WiFi Advisor in close proximity to where the Wireless Access Point (or Residential Gateway) will be installed. Take a second WiFi Advisor along with your iPad to the location where WiFi performance is to be assessed. The test thoroughly evaluates WiFi performance between the two locations. Move to the next location of interest and repeat the test to the Access Point. Continue until all locations of interest have been performance tested. If desired, the test results are saved to the active job or work ticket or associated with a new job. (See the “Managing jobs” section for more details regarding work flow with job / tickets). The two-ended site assessment test includes the following features: December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 25 Chapter 3 Testing Assessing WiFi performance throughout a site • Innovative TrueMargin™ performance test which thoroughly and simultaneously evaluates the physical layer, the 802.11 transport layer and the packet layer. • BSSID / AP view snapshot for each test location • Spectral snapshots at both ends of the wireless link • Best Channel recommendations for 2.4G / 5G for the given test profile • Ability to evaluate WiFi performance at multiple locations within the home • WiFi Network Optimization recommendations Getting started In order to get started with site assessment test, you must have two registered WiFi Advisors connected over Bluetooth. To get started Launch the WiFi Advisor app. Select Two-Ended Site Assessment. Specifying settings During Site Assessment test, up to five individual test profiles are configured that are repeated at each location. The test profiles run sequentially at each location, and always in the same order. Each Site Assessment configuration has a Primary Profile, with up to four additional profiles, known as Secondary Profiles. Only the Primary Profile is associated with Pass/Fail or Closeout testing. The Secondary Profiles are informational, rather than Pass/Fail. At the beginning of the Site Assessment, the Secondary Profiles can be enabled or disabled as a group. This allows for rapid Site Assessment testing if only the Primary Profile is desired. Step 1: Selecting devices The first setting to specify is selecting which device is the access point and which is the station. Page 26 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Chapter 3 Testing Assessing WiFi performance throughout a site To select devices From the Site Assessment page, select Devices.

Topics discussed in this chapter include the following: • “WiFi deployment” on page 50 • “Network standard” on page 50 • “802.11 specifications” on page 51 • “Spectrum Differences” on page 51 December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 49 Appendix B WiFi Fundamentals WiFi deployment WiFi deployment Successful WiFi service delivery is highly dependent on a vulnerable RF physical medium that is dynamically shared, along with complex L2 (i.e. 802.11) and supporting protocols. This makes installation of service a potentially complex task. Reliance on simplistic installation methods that do not provide an indication of robust service level margin can impact QoE (quality of experience) as the RF environment / network changes, resulting in trouble calls, repeats and churn. Inability to assess 802.11 performance and true throughput at critical locations throughout the home leaves the end user guessing as to how the installed network should perform, leading to trouble calls and truck rolls as the end user adds to / modifies the WiFi network. Network standard The network standard uses RF (radio frequency) spectrum as the physical layer. That means no wires, but can have issues with walls, mirrors and certain other building materials. The network standard has protocols to handle some interferers, such as: Page 50 • Co-channel (same channel) interferers can cooperate transmission (take turns). • Burst interference mitigation by delayed transmission • Adjacent Channel interferers are an issue • Non-802.11 interferers are a big problem because they can appear as 802.11 but do not adhere to protocols. Your 802.11 radio will wait to get the “ok” to transmit, which may never come. It also can de-sensitize the receiver since the packets may not be received, the transmitter will keep sending the message “waiting for an acknowledgement” WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Appendix B WiFi Fundamentals 802.11 specifications 802.11 specifications 802.11 is the “parent” of a family of Institute of Electronics and Electronic Engineering (IEEE) specifications for wireless LAN. The standard has undergone several revisions: 802.11a Main Frequency Band (GHz) 54 20 OFDM No 802.11b 2.4 11 22 DSSS No 802.11g 2.4 54 20 OFDM/DSSS No 802.11n 2.4/5 65/135 20/40 OFDM 802.11ac 86/180/390/780 20/40/80/160 OFDM Protocol Max Data Rate (Mbps) BW (MHz) Modulation MIMO Support? Spectrum Differences Understanding the different spectrums and channel allocations can help identify trouble areas. 2.4 GHz Spectrum In North America, there are 11 channels, each 22 MHz wide. These channels overlap, except for 1, 6 and 11. Thus, these channels are always preferred. The rest of the world includes two additional channels (12 and 13). Figure 16 provides a map of the channel allocation for the 2.4 Ghz spectrum. Industrial, Science and Mechanical (ISM)” is the band that can be used by anything that December 2014 WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 51 Appendix B WiFi Fundamentals Spectrum Differences gets a FCC Part 15 approval (Bluetooth devices, cordless telephones, baby monitors and microwave ovens). Figure 16 Page 52 2.4G channel allocation WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 December 2014 Appendix B WiFi Fundamentals Spectrum Differences 5 GHz Spectrum A lot of these frequencies are used for satellite communications (low power). That means to them, WiFi is the interferer. U-NII stands for Unlicensed National Information Infrastructure and was set aside primarily for WiFi use. Most of the world uses the spectrum from 5.18 – 5.835 GHz. Note that another ISM band exists here (cordless telephones, point-to-point radios, baby monitors). Figure 17 provides a map of the channel allocation for the 5 Ghz spectrum. Figure 17 December 2014 5G channel allocation WiFi Advisor Wireless LAN Analyzer User’s Guide 22073751, Rev. 002 Page 53 Appendix B WiFi Fundamentals Spectrum Differences This band can vary in a greater number of regions, as shown in Figure 18, and.certain channels are designated as indoor use only or outdoor use. Figure 18 International channel map The terms “Indoor” or “Outdoor” relate to output power restrictions on the radios.
