Granular control over bandwidth, apps, and client devices

Get up-to-date insights into clients and application usage thanks to cloud-automated classification and device fingerprinting.

Ensure network stability and higher productivity by prioritizing mission critical apps and throttling low-priority ones.

Ensure baseline security and consistency across sites while drastically reducing deployment time with configuration templates.

Powerful heuristics for smarter wireless troubleshooting

Meraki Wireless Health: A powerful heuristics engine that rapidly identifies anomalies impacting end users’ experience across every stage of client

connectivity — association, authentication, IP addressing, and DNS availability — for rapid root cause analysis and response.

Quickly identify worst-performing access points & client devices, problematic latency, and specific failure reasons

Integrated analytics for actionable insights

Leverage out-of-the-box analytics to understand client behavior and foot traffic across sites and venues.

Use location data to make informed decisions about staffing, event or storefront displays, advertising — even AP placement.

Integrate raw, real-time data with business intelligence systems and perform deeper analysis using built-in API.

Advanced TroubleshootingGoing beyond the controller options

Alex Wilson

Goals

Identify and discuss…

• Advanced troubleshooting options

• Changing workplace environment

• Designing a new system

Most common test…• Speed Test

• Done from the client to a known server

• Returns the download and upload throughput plus latency

• Limited value

What causes low throughput?• Low signal strength

• Interference

• Channel width settings

• Spatial stream support

• Band being used

Going Beyond the Controller

• Signal strength checks

• Spectrum analysis

• Comprehensive troubleshooting

Signal Strength Checks

• Can be done with pretty much any network device

• iOS devices have limited options

• Limited usefulness – not the full picture

• Not all devices are created equal

• Hard to isolate selected access point

What defines a “good” signal

• Best signal is -30dBm

• Worst would be -100dBm

• Every application / system has different needs

We have a good signal but…

• The network still isn’t that great

• Signal strength doesn’t tell you about interference

• Could be weak client devices

• Roaming not working

Now what?

• Throughput said there was “some” problem

• Signal strength showed there were some dead spots or was inconclusive

• Now what?

Spectrum Analysis

• Requires specialized tools

• Reads the spectrum and helps find issues

• Requires advanced knowledge to make sense of findings

Tools of the trade• Limited use tools

• Metageek WiSpy, RF Explorer

• Full featured tools• Ekahau with Sidekick, AirMagnet

• iBwave, Acrylic, TamoSoft, VisiWave

What can we learn?

• Identify and potentially locate interference sources

• Analyze channel use

Getting a bit better…

• We know we have throughput issues

• We found our dead and weak spots

• We found we have spectrum use issues

• We fixed the above and still have throughput issues

• Now what?

Detailed professional assessment

• WiFi site survey conducted by wireless engineer

• Uses professional grade tools

• Looks at more than just signal strength

Results from Actual Survey• Client is a winery with six access points

• Slow page loads, dropped connections, dropped or garbled WiFi calls, frequent DHCP issues

• POS terminals dropping transactions causing double charges sometimes

Outcome of an Assessment

• Changing configuration

• Moving, adding, removing access points

• Upgrading certain access points

• System replacement

• Good neighbor policy

Our Findings

• Interference

• Several APs mounted on the wall, not flat

• Wrong APs for situation

• Weak coverage outside

Summarizing troubleshooting

• Start with the controller options

• Signal strength tests

• Spectrum analysis

• Professional troubleshooting survey and report

New WiFi Network Design

• WiFi needs to be designed correctly

• Guessing is not “correctly”

• Neither is 1:1 replacement

Common Things that go Wrong

• Old location was bad, why would it be better now?

• New radiation patterns

• Different standards supported

• Different options altering the entire experience

• New access points will just be better right?

Planning on Moving to WiFi 6?

• You need to design for it if you want to take advantage of it

• Coverage will be different due to new APs and new features

Options to Create a Good Design• Use the right partner to get it done

• AP on a Stick Design

• Predictive Design with Onsite Review / Testing

• Pure Predictive Design

Wrapping up• Use your controller to start the troubleshooting process

• Move to basic tools next to attempt to isolate some issues

• If you can’t resolve it, move to a professional troubleshooting survey

• If designing a new system, do it right to avoid the common pitfalls
