Before you call your ISP and sit on hold for forty-five minutes, work through this checklist. The majority of slow internet complaints are resolved by one of the first three steps, and they all take under five minutes. The goal here is to isolate the problem: is it your equipment, your local network, your ISP, or external congestion? Each step narrows the field.
The Diagnostic Process
Establish a Baseline: Run a Speed Test
Go to VelocityVerify right now, before changing anything. Write down your download speed, upload speed, ping, and jitter. This is your baseline. You need data to know if subsequent steps actually improved anything, and you need it if you end up calling your ISP.
Isolate Wi-Fi vs. the Line
Plug your computer directly into your router with an Ethernet cable and run the speed test again. If your wired speed is significantly better than wireless, your problem is Wi-Fi interference or range, not your internet connection. If both tests are equally slow, the problem is upstream of your router.
Power Cycle Your Modem and Router
Unplug both devices from power. Wait a full 30 seconds — not 5 seconds, 30 seconds. Plug the modem back in first. Wait for it to fully connect (the lights will stabilize, usually 60–90 seconds). Then plug in the router. Test again. This resolves a surprisingly large percentage of problems and costs you nothing.
Find What Else Is Consuming Your Bandwidth
Check your router's admin panel (usually at 192.168.1.1 or 192.168.0.1) for a list of connected devices and their traffic. Common culprits: phones doing a silent iOS or Android update, a gaming console downloading a patch in the background, a smart TV running pre-loading, or a security camera uploading footage. Identify and pause them, then retest.
Test at Different Times of Day
Run speed tests at 7 AM, 12 PM, and 9 PM on a weekday. If your morning speeds match your plan but evening speeds are significantly lower, your ISP's network is congested during peak hours. This is an infrastructure problem on their side, not a problem with your equipment. No amount of rebooting will fix it.
Call Your ISP With Data, Not Frustration
If you are consistently getting speeds significantly below your paid plan — measured at the modem level using a wired connection — you have a legitimate service complaint. Contact your ISP with your timestamped speed test results. Ask them to check the signal levels on your modem remotely. Poor signal-to-noise ratio, high uncorrectable errors, and low power levels on the line are all things a technician can measure and fix. Speeds below 80% of your plan consistently constitute a service level agreement violation in most markets.
Wi-Fi Specific Fixes
If Step 2 showed your wired connection is fine but Wi-Fi is slow, these steps apply:
- Change your Wi-Fi channel. Use a free tool like WiFi Analyzer (Android) to see which channels are congested in your area. Most routers should be on channels 1, 6, or 11 on 2.4 GHz to avoid overlapping with neighbors.
- Move to 5 GHz. The 5 GHz band is less congested and faster at short range. If your device is close to the router, always prefer 5 GHz.
- Reduce interference sources. Microwaves, cordless phones, baby monitors, and Bluetooth devices all interfere with 2.4 GHz signals. Move your router away from these devices.
- Update router firmware. Router manufacturers regularly release firmware updates that fix bugs and improve performance. Check your router's admin panel for a firmware update option.
