AI Analysis Summary

Internet performance degrades significantly during peak hours, making it nearly unusable despite a higher-tier plan. The user suspects local network congestion as the primary culprit.

Problème signalé

During peak hours, my internet becomes almost unusable. I suspect network congestion in my area is causing these severe slowdowns, even though my plan should be faster.

Questions

5 questions

Causes identifiées

3 causes
#1

Local Network Congestion

80%

During peak hours, a high number of users in your immediate area are simultaneously using the internet, overwhelming the shared bandwidth provided by your ISP. This is common with cable and DSL services.

#2

Outdated or Inadequate Router/Modem

50%

Your modem or router may not be capable of handling the speeds your plan offers or managing multiple devices efficiently, especially under heavy load.

#3

Internal Network Issues

30%

Problems within your home network, such as too many devices, background processes, or faulty network cables, could be consuming bandwidth or causing bottlenecks.

Solutions recommandées

9 solutions
💡

Contact Your ISP

95%Official
Inquire about network upgrades or potential oversubscription in your neighborhood. Ask if they offer a static IP or a business plan which might have better prioritization.

🤖 AI Analysis

"The user explicitly suspects network congestion in their area during peak hours. Contacting the ISP is the most direct way to address this, as they can confirm or deny congestion, discuss potential upgrades, and explore options like business plans for better prioritization, which directly tackles the core of the user's suspicion."

💡

Schedule Usage

85%Official
If possible, shift bandwidth-intensive activities (like large downloads or streaming) to off-peak hours.

🤖 AI Analysis

"The problem occurs during specific 'peak hours' (weekdays, 5 PM - 10 PM). Scheduling bandwidth-intensive activities to off-peak hours is a practical workaround for network congestion, directly mitigating the impact of the problem when it's most severe."

💡

Limit Connected Devices

80%Official
Temporarily disconnect non-essential devices during peak hours to see if performance improves.

🤖 AI Analysis

"The user has 6 devices connected during peak hours. Limiting the number of connected devices is a direct way to reduce the load on the network during congested periods, which could alleviate the 'unusable' internet experience. This is a good troubleshooting step to isolate the issue."

💡

Check for Background Processes

75%Official
Ensure no devices are running large downloads, updates, or intensive online activities without your knowledge.

🤖 AI Analysis

"While the user suspects area congestion, it's possible that background processes on one or more of the 6 devices are contributing to the perceived slowness. Checking for these hidden bandwidth hogs is a crucial step in diagnosing whether the issue is solely external or also internal to the user's network."

💡

Test Wired Connection

70%Official
Connect a device directly to the router via Ethernet cable to rule out Wi-Fi interference or signal strength issues.

🤖 AI Analysis

"The user is experiencing issues during peak hours, which could be exacerbated by Wi-Fi interference or signal strength problems, especially with multiple devices. Testing a wired connection helps to isolate whether the problem lies with the internet service itself or the Wi-Fi network."

💡

Upgrade Your Plan (with caution)

65%Official
While you have a faster plan, it might still be subject to congestion. Discuss with your ISP if a higher tier plan or a different technology (like fiber) is available and would truly bypass local congestion.

🤖 AI Analysis

"Although the user has a cable connection, and the problem is suspected to be congestion, upgrading their plan or technology (like fiber) is a potential solution if the ISP confirms that their current plan is insufficient or if a better technology is available that bypasses local congestion. However, it's less direct than contacting the ISP first."

💡

Check Equipment Compatibility

50%Official
Ensure your modem and router are rated for the speeds of your internet plan and support the latest Wi-Fi standards (e.g., Wi-Fi 6).

🤖 AI Analysis

"While outdated equipment can cause performance issues, the user's problem is specifically tied to 'peak hours' and suspected 'network congestion.' This suggests the issue is more likely with the ISP's infrastructure during high demand rather than the user's equipment being fundamentally incapable of handling their plan's speeds at all times."

💡

Upgrade Equipment

45%Official
Consider purchasing a newer, more powerful router or a combination modem/router unit from your ISP or a reputable third-party manufacturer.

🤖 AI Analysis

"Similar to checking compatibility, upgrading equipment is a good general troubleshooting step, but it's less likely to be the primary cause of a problem that only occurs during peak hours and is suspected to be network congestion. The user's speeds are reported as 'terrible, like 5 Mbps down' during peak, which is a significant drop, suggesting an external bottleneck."

💡

Restart Equipment

30%Official
A simple power cycle of your modem and router can sometimes resolve temporary performance issues.

🤖 AI Analysis

"Restarting equipment is a basic troubleshooting step that can resolve temporary glitches. However, the problem is consistently occurring during peak hours, suggesting a more systemic issue than a temporary equipment hiccup. It's worth trying, but unlikely to be the sole solution for a recurring peak-hour problem."
