A. Replace gateway
B. Review alarm history, error logs, and patterns
C. Replace SFP/ONT
D. Reprovision Wi-Fi SSID
B. Review alarm history, error logs, and patterns
When a customer statement most strongly indicates an expectation issue rather than a service issue?
A. "The gateway has no lights"
B. "My wired test is fine, but Wi-Fi is slower in the back bedroom."
C. "The gateway has a red light."
D. " Nothing is connected."
B. "My wired test is fine, but Wi-Fi is slower in the back bedroom."
A customer has sync at the gateway but no service authentication. Which device is most likely responsible for passing customer traffic after optical conversion?
A. Drop
B. Jumper
C. Gateway
D. Slack NID
C. Gateway
A customer reports slow speeds, but hardwired tests pass at provisioned rate. What is the most likely fault domain?
A. PFP issue
B. Optical Attenuation
C. Wi-Fi environment / Client limitation
D. ONT registration failure
C. Wi-Fi environment / Client limitation
What is the most effective way to prevent a Wi-Fi related repeat dispatch?
A. Replace ONT/SFP
B. Reboot Gateway
C. Educate Customer Wi-Fi expecations
D. Increase speed tier plan

What is most likely a result of excessive bend stress on a fiber jumper?
A. Gateway reboot loop
B. Increased optical attenuation
C. Ethernet negotiation failure
D. IP conflict
B. Increased optical attenuation
A red alarm with intermittent optical recovery most strongly suggests:
A. Stable customer LAN issue
B. Dirty, loose, or marginal optical connection
C. Billing issue
D. DNS cache issue
B. Dirty, loose, or marginal optical connection
A customer says "My internet is slow," but only one older device is affected, Best conclusion?
A. Fiber impairment
B. Device-Specific limitation
C. ONT/SFP failure
D. Splitter issue
B. Device-Specific limitation
A clean connector with poor light levels and no visible damage should lead a Tech to suspect:
A. Customer Wi-Fi congestion
B. Incorrect SSID assignment
C. Upstream optical impairment or macro bend
D. Gateway firmware issue
C. Upstream optical impairment or macro bend
A customer has no service after a storm. Gateway has power, ONT is down, flashing red. Most probable root cause?
A. Wi-Fi congestion
B. Customer changed password
C. Physical Plant / Signal loss
D. App sync issue
C. Physical Plant / Signal loss
What creates the highest callback risk at install completion?
A. Slightly long ethernet jumper
B. Missing Fiber Jack
C. Poor expectation and incomplete service validation
D. Extra slack in Slack NID
C. Poor expectation and incomplete service validation
What is the best justification for hardwired speed testing during install validation?
A. To confirm TV resolution
B. To isolate access speed from Wi-Fi variables
C. To test customer devices only
D. To verify app login
B. To isolate access speed from Wi-Fi variables
What is the strongest indicator a trouble is inside rather than outside?
A. No optical light
B. Red flashing light at Gateway
C. Good optical sync but service issue isolated to LAN / Wi-Fi
D. PFP outage
C. Good optical sync but service issue isolated to LAN / Wi-Fi
Which action improves first time resolution?
A. Fast closeout
B. Replace equipment proactively
C. Validate service, educate customer
