📋 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.

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. Sincerely, [YOUR_NAME] [SERVICE_ADDRESS] [PHONE] [EMAIL] Enclosures: [LIST_DOCUMENTS]

Sincerely,

[Your Signature]
