Step-by-Step Troubleshooting Guides
Select the issue that best describes your problem for a detailed walkthrough.
My Internet Is Completely Down
- 1Check if the outage is widespread. Visit your ISP's website or social media pages on your phone (using cellular data) to see if there is a reported outage in your area.
- 2Power cycle your modem and router. Unplug both devices from power, wait 30 seconds, then plug the modem in first. Wait for all lights to stabilize (about 2 minutes), then plug in your router.
- 3Check all cable connections. Make sure the coaxial cable (for cable internet) or Ethernet cable from the wall is firmly connected to your modem. Also check the Ethernet cable between your modem and router.
- 4Look at the lights on your modem. If the “online” or “internet” light is off or blinking red, the problem is between your modem and the ISP. If all modem lights look normal, the issue may be your router.
- 5Try connecting a device directly to the modem with an Ethernet cable, bypassing the router entirely. If you get internet this way, the problem is your router. If not, call your ISP.
My Internet Is Slow
- 1Run a speed test at Pong.com to measure your current download, upload, and ping. Compare the results to what your ISP plan promises.
- 2Test with a wired Ethernet connection instead of Wi-Fi. If speeds improve significantly on a wired connection, the problem is your Wi-Fi, not your ISP.
- 3Check how many devices are using the network. Streaming video, large downloads, cloud backups, and software updates on other devices can consume your bandwidth.
- 4Restart your modem and router. A simple reboot clears temporary memory issues and often resolves slow performance.
- 5Check for bufferbloat. Run the Pong speed test and look at the bufferbloat result. If your latency spikes during the download test, enable SQM or QoS on your router.
- 6Test at different times of day. If speeds are consistently slow during evening hours (7pm to 11pm), your ISP may have congestion in your area. Contact them to discuss the issue or consider upgrading your plan.
My Wi-Fi Keeps Disconnecting
- 1Move closer to your router and see if the disconnections stop. If they do, the issue is signal range. Consider adding a mesh Wi-Fi system or a Wi-Fi extender to cover dead zones.
- 2Switch to the 5GHz band if you are on 2.4GHz. The 2.4GHz band is more crowded and prone to interference from microwaves, baby monitors, and neighboring networks. The 5GHz band is faster and less congested.
- 3Change your Wi-Fi channel in your router settings. Log into your router admin page (usually 192.168.1.1 or 192.168.0.1) and try channels 1, 6, or 11 for the 2.4GHz band.
- 4Update your router's firmware. Check your manufacturer's website or router admin page for available updates. Outdated firmware can cause instability and security vulnerabilities.
- 5Check if your router is overheating. Make sure it is in a well-ventilated area, not inside a cabinet or stacked under other electronics. If the router is more than 4 to 5 years old, it may need to be replaced.
High Ping or Lag in Games
- 1Use a wired Ethernet connection instead of Wi-Fi. Wi-Fi adds latency and introduces jitter. For competitive gaming, a wired connection can reduce ping by 10 to 30ms and dramatically reduce jitter.
- 2Close bandwidth-heavy applications on your network. Streaming video (Netflix, YouTube), large downloads, and cloud backups running on any device on your network will increase your ping.
- 3Enable QoS (Quality of Service) on your router to prioritize gaming traffic. If your router supports SQM (Smart Queue Management), enable it to fight bufferbloat, which is one of the biggest causes of lag spikes.
- 4Connect to game servers that are geographically closer to you. Most games let you choose your server region. Selecting a server in your region (or the closest one) will give you the lowest possible ping.
Video Calls Keep Buffering
- 1Check your upload speed. Video calls require at least 3 to 5 Mbps upload for HD quality. Run a speed test at Pong.com and look at your upload result. If it is below 5 Mbps, that is likely the bottleneck.
- 2Close other applications and browser tabs during calls. Background uploads, cloud syncing (Dropbox, Google Drive, iCloud), and streaming on other devices all compete for your upload bandwidth.
- 3Move closer to your Wi-Fi router or switch to a wired Ethernet connection. Wi-Fi signal drops significantly through walls and floors. Video calls are especially sensitive to connection instability.
- 4Lower the video quality in your calling app. Most apps (Zoom, Google Meet, Teams) allow you to reduce video resolution. Dropping from 1080p to 720p cuts bandwidth requirements in half and often eliminates buffering.

Why is my internet so slow?
Slow internet can be caused by Wi-Fi interference, too many devices on your network, ISP congestion during peak hours, bufferbloat, outdated router firmware, or a plan that does not provide enough bandwidth. Start by running a speed test to see your actual speeds, then test on a wired connection to rule out Wi-Fi issues.
Should I restart my router?
Yes. Restarting your router and modem is the single most effective first step for fixing internet problems. Unplug both devices, wait 30 seconds, plug in the modem first and wait 2 minutes, then plug in the router. This clears temporary memory issues, refreshes your connection to your ISP, and resolves most intermittent problems.
How often should I replace my router?
Most routers should be replaced every 3 to 5 years. Older routers may not support newer Wi-Fi standards (Wi-Fi 6 or Wi-Fi 6E), lack important security patches, and struggle with the number of devices in modern households. If your router is more than 4 years old and you are experiencing performance issues, upgrading is likely worthwhile.
When should I call my ISP?
Call your ISP if your internet is completely down and restarting your modem does not help, your speeds are consistently well below what your plan promises (test with a wired connection), you notice frequent disconnections throughout the day, or the modem lights indicate a connection error. Before calling, note down your speed test results as evidence.
What is bufferbloat?
Bufferbloat is a networking problem where excessive buffering in your router causes high latency under load. When someone on your network is downloading a large file or streaming video, bufferbloat causes your ping to spike dramatically, leading to lag in games, choppy video calls, and sluggish web browsing. The fix is to enable SQM (Smart Queue Management) on your router.
How can I tell if my ISP is throttling me?
Run speed tests at different times of day and compare results. If your speeds are significantly slower during peak evening hours (7pm to 11pm) but fast during off-peak times, congestion or throttling may be occurring. Also try testing with a VPN. If speeds improve with a VPN, your ISP may be throttling specific types of traffic.
Why does my internet slow down at night?
Internet speeds often drop in the evening because more people in your neighborhood are online simultaneously, creating congestion. Cable internet is especially susceptible to this because bandwidth is shared among nearby subscribers. If evening slowdowns are severe, consider upgrading to fiber (which does not share bandwidth) or contacting your ISP about the congestion.
What internet speed do I actually need?
For basic browsing and email, 25 Mbps is sufficient. For streaming HD video, aim for 50 Mbps. For a household with multiple users streaming, gaming, and video calling simultaneously, 100 to 300 Mbps is recommended. For remote work with large file transfers and video conferencing, 200 Mbps or more provides a comfortable margin.
