Troubleshooting Slow Internet Connections

A sluggish internet connection can be highly frustrating and debilitating. From buffering videos to crawling downloads, slow internet speeds can hinder productivity and dampen online experiences. While internet service providers (ISPs) play a significant role in determining the overall connection quality, there are several factors within your control that can help improve your internet speed. In this article, we will explore some common reasons why your internet connection may be slow and provide practical tips to help optimize it. Additionally, we will delve into how both Ethernet and WiFi connections can also limit your overall speed on the internet.

Bandwidth Limitations

One of the most common reasons for slow internet speeds is bandwidth limitations. Bandwidth refers to the maximum data transfer rate supported by your internet plan. If you have several devices simultaneously using the internet or are engaged in data-intensive activities like streaming 4K videos or gaming, your available bandwidth may get divided, leading to reduced speeds for each device or activity.

Solution: Consider upgrading to a higher-tier internet plan with increased bandwidth. Analyze your internet usage requirements and opt for a plan that can accommodate your needs, especially if you have a household with multiple connected devices. Also keep in mind that if you’re using a 3rd party router, it could be limiting your speeds. Confirm your router supports the necessary throughput speeds to provide you the max throughput from your ISP. 

Router Placement and Interference

The placement of your wireless router can significantly impact internet speeds. If your router is situated far away from your devices or is obstructed by walls and objects, it may result in weak signals and lower connection speeds. Moreover, interference from neighboring WiFi networks, Bluetooth devices, and other electronic appliances can also disrupt your signal.

Solution: Position your router in a central location within your home or office, away from thick walls and obstructions. Ensure there are minimal electronics or physical barriers between your devices and the router. Additionally, access your router settings to switch to less congested WiFi channels for improved signal quality.

Ethernet and WiFi Connection Speeds

Apart from ISP-related issues and router concerns, the type of connection you use can also influence your overall internet speed. Ethernet connections, typically faster and more stable, can outperform WiFi connections. While WiFi offers the convenience of wireless connectivity, it may not match the speeds of a wired Ethernet connection, especially over longer distances.

Solution: Utilize Ethernet for High-Performance Needs. For activities that require higher speeds and low latency, consider using an Ethernet connection instead of WiFi. Connect your devices directly to the router via Ethernet cables for enhanced performance, especially when engaging in tasks like online gaming, video conferencing, or large file transfers.

Outdated Hardware

Over time, the technology used in your modem, router, and network cards can become outdated, limiting their ability to handle higher internet speeds. Using older equipment may bottleneck your connection and result in slow internet speeds.

Solution: Invest in modern and higher-performance networking equipment. Upgrading your router, modem, and network cards to the latest standards can significantly improve internet speeds and enhance your online experience.

Network Overload

In densely populated areas or in scenarios where many users are connected to the same ISP infrastructure, network overload can occur. During peak hours when many users are simultaneously accessing the internet, the overall network speed may be impacted.

Solution: Try to schedule data-intensive activities like large downloads or high-definition streaming during off-peak hours when the network is less congested. This can help you access more available bandwidth and improve your overall internet speed.

Speed Tests

Not all speed tests are alike. Some tests are limited to the upload and download speeds. Latency and jitter are important to how your Internet connection performs for applications such as VoIP (voice over IP) and video meetings. The device you’re testing from as well as the distance to the server you’re testing against will be factored into your overall result. 

Solution: Use a device with an Ethernet connection to test. This will ensure you’re not getting any interference over WiFi. Choosing a server closer to your location will provide you with a more accurate reading. As will closing background applications when running tests. This will take any extra load off the connection.

Why Won’t My Peplink Connect with WiFi as WAN?

Most WiFi WAN issues are related to the signal strength to the Peplink, interference in the environment, as well as how the WiFi network you’re connecting to is managed (i.e. from Hotel, campground, coffee shop, etc). There’s a few tips we’ve gathered that can help to troubleshoot some common connection issues. Read on to learn more. 

Confirm Connectivity with the WiFi Source

Take your mobile device or computer and try connecting to the WiFi WAN source directly. This will show you how initial connections are established – whether there is a splash page; their connection password and frequency – as well as the performance of the network. Keep in mind that users can see bandwidth degradation of up to 50% [when connected through the Peplink], depending on conditions. 

Confirm You’re Following the Proper Configuration Steps 

  1. [Depending on model] enable (OR, drag and drop from the left) only 5ghz OR 2.4ghz WiFi WAN to the priority needed
  2. Wait until the status says scanning
  3. Click on the wireless networks button
  4. Click the Connect button next to the network you are trying to connect to and enter the password when prompted.
  5. Click Save
  6. Wait for the Star or Check Mark to show up beside the network
  7. If needed, click Connect again next to the network
  8. Select OK
  9. Wait for the status to show Connected (This can take a few mins.)

Upgrade the firmware

If the firmware is not up to date, this could help resolve the issue. Go to System -> Firmware to check for firmware , or manually upgrade the firmware if needed. 

Check Signal Strength

  1. Log into your Peplink web admin and refer to the Dashboard page -> WAN Connection Status -> WiFi WAN. Click on the Wireless Networks button here.
  2. In the window that opens, you’ll see a table showing the WiFi names, channel, security and signal. The signal is represented by a negative number. The closer this number is to 0, the better the signal is. Generally, a signal of -80dBm or closer to 0 is needed to maintain the WiFi WAN connection. However, interference and obstructions between your Peplink’s WiFi signal and the WiFi WAN source can still cause issues with a stronger signal. 

Check Channel Settings

  1. In the same window (with the list of wireless networks), refer to the Channel column and make note of the channels in use. 
  2. Close the Wireless Networks window and click on the Details button to the right
  3. Scroll down to the Wi-Fi WAN Settings section
  4. Adjust Channel Width from 20MHz to 20/40Mhz
  5. If you found that most nearby networks are on the same channels in step #3 above, set the Channel to Custom and then select a channel not used or less used. Ideally, the channel selected should be as far away from the in use channels as possible. 

Adjust the Output Power

  1. The Output Power can be adjusted to control how much signal is broadcast to pull in the WiFi WAN connection. If you’re in a heavily congested WiFi area, sometimes lowering the power may provide better results. You can also enable the Boost to add extra power. 
  2. Click Save and Apply at the bottom when done. 

Change the DNS server setting

Changing the DNS server to match the IP address of its network could also help if nothing else does. When you create the WiFi connection profile (by clicking on the “Connect” button under the “Wireless Networks”) uncheck the box to “obtain DNS server address automatically.” Then, check the box to “use the following DNS server addresses.” Enter the Gateway/ Router IP address of the WiFi network in “DNS Server 1.” For “DNS Server 2” we entered one of Google’s DNS server addresses (8.8.8.8), but you may use a different server address if desired.
