📋 Internet Speed Throttling Demand Letter Overview
Internet service providers often throttle bandwidth during peak hours, limit speeds for specific applications like streaming or gaming, or fail to deliver advertised speeds. While net neutrality protections have varied, consumers retain rights under federal transparency rules and state consumer protection laws to receive the service they pay for.
Common ISP Throttling Scenarios
activity Application-Specific Throttling
ISP slows speeds for Netflix, YouTube, gaming, or torrenting while maintaining normal speeds for web browsing.
clock Peak Hour Speed Reduction
Dramatic speed drops during evening hours despite paying for unlimited service at specific speeds.
trending-down Data Cap Throttling
Speeds reduced to dial-up levels after exceeding monthly data limits not clearly disclosed at signup.
wifi Consistent Underperformance
Actual speeds consistently 50%+ below advertised rates without explanation or billing adjustment.
⚠ Document Speed Tests Properly
Use FCC-approved testing tools like the FCC Speed Test app or wired connections to official test servers. Run tests at multiple times over several days. WiFi-only tests are often dismissed by ISPs as user equipment issues.
⚖ Legal Basis
While net neutrality rules have changed, ISPs remain subject to FCC transparency requirements and must deliver services substantially as advertised or face regulatory action.
47 USC § 230 - Communications Decency Act
While primarily addressing platform liability, Section 230 establishes that internet services are governed by federal telecommunications law. The FCC retains authority to enforce transparency and consumer protection rules even without strict net neutrality mandates.
47 CFR § 8.3 - Transparency Rule
Requires ISPs to publicly disclose network management practices, performance characteristics, and commercial terms of service. Providers must accurately describe speeds, data caps, throttling practices, and network congestion policies.
FCC Broadband Consumer Labels (2024)
Mandates nutrition-style labels for internet service plans showing typical speeds, data allowances, and fees. ISPs failing to deliver speeds within reasonable tolerance of advertised rates face enforcement action and must provide billing credits.
State Consumer Protection Acts
Many states prohibit deceptive advertising of internet speeds. Attorneys general have pursued ISPs for advertising 'up to' speeds rarely delivered. Consumers can pursue claims under state UDAP statutes regardless of federal net neutrality status.
47 USC § 201 - Telecommunications Act
Requires that charges and services be just and reasonable. Courts have applied this to internet service pricing and performance, particularly where ISPs categorically fail to deliver advertised speeds.
💡 File Concurrent FCC Complaint
Submit a complaint through the FCC Consumer Complaint Center (consumercomplaints.fcc.gov) simultaneously with your demand letter. ISPs take FCC complaints seriously as they trigger formal investigations. Reference your FCC complaint number in correspondence with the ISP.

RE: Re: Service Performance Dispute - Account #[ACCOUNT_NUMBER]
Dear Sir or Madam:
Dear Executive Customer Service: I am writing to formally dispute the internet service performance provided under account #[ACCOUNT_NUMBER] at [SERVICE_ADDRESS]. Despite paying for [ADVERTISED_SPEED] Mbps service, I consistently receive speeds averaging [ACTUAL_SPEED] Mbps - approximately [PERCENTAGE]% of advertised performance. Performance Issues Documented: Between [START_DATE] and [END_DATE], I conducted systematic speed testing using the FCC Speed Test app and wired ethernet connection to eliminate WiFi variables. Results show: - Average download speed: [AVG_DOWNLOAD] Mbps (advertised: [ADVERTISED_DOWNLOAD] Mbps) - Average upload speed: [AVG_UPLOAD] Mbps (advertised: [ADVERTISED_UPLOAD] Mbps) - Peak hour degradation: speeds drop to [PEAK_SPEED] Mbps between 7-11pm [IF_APPLICABLE: - Application-specific throttling: [STREAMING_SERVICE] consistently throttled to [SPEED] while general browsing maintains [SPEED]] Failed Resolution Attempts: I contacted customer service on [DATES] (ticket #s [TICKET_NUMBERS]). Despite [MODEM_REPLACEMENT/TECHNICIAN_VISIT/ETC], performance remains substantially below advertised levels. Your representatives attributed issues to [EXCUSE_GIVEN], which does not excuse contractual performance obligations. Legal Violations: Your failure to deliver advertised speeds violates: 1. 47 CFR § 8.3 Transparency Rule: Required disclosure of actual network performance vs. advertised speeds 2. FCC Broadband Label Requirements: Material deviation from typical speeds disclosed in service labels 3. [STATE] Consumer Protection Act: Deceptive advertising of internet speeds not consistently delivered 4. Breach of Contract: Failure to provide service as specified in our agreement dated [CONTRACT_DATE] Demands for Resolution: 1. Service Performance Correction: Immediate technical resolution to deliver contracted speeds of [ADVERTISED_SPEED] Mbps 2. Billing Adjustment: Refund of [TIMEFRAME] months of service fees, prorated to reflect actual vs. advertised performance ([PERCENTAGE]% reduction = $[REFUND_AMOUNT]) 3. Service Upgrade or Rate Reduction: Either upgrade to higher tier at current price to achieve target speeds, or reduce billing to match actual performance tier 4. Written Guarantee: Documented commitment to maintain advertised speeds or automatic billing credits for underperformance Supporting Documentation: Enclosed: - Speed test results log ([NUMBER] tests over [TIMEFRAME]) - Service agreement showing advertised speeds - Billing statements for affected period - Customer service correspondence - FCC complaint confirmation #[FCC_COMPLAINT_NUMBER] Timeline for Response: I expect written response within 14 days outlining technical remediation plan and billing adjustment. Failure to resolve this matter will result in: - Escalation of FCC complaint with additional documentation - Filing complaint with [STATE] Attorney General Consumer Protection Division - Pursuing claims under [STATE] consumer protection statutes with statutory damages and attorney fees - Public disclosure of performance failures on consumer review platforms I prefer to resolve this matter cooperatively but will exercise all available legal remedies if necessary.
