A slow wireless router can hamper your internet experience and negatively impact all your Wi-Fi connected devices. If your router is taking too long to load webpages and online content or experiencing frequent buffering, there could be several reasons why your wireless router is underperforming. Follow this troubleshooting guide to identify what’s slowing your router and fix the issues for faster speeds.
Older Router Model
If your router is quite outdated, for instance 5-6 years old, it may not support the latest wireless standards and advanced features that reduce congestion and interference for better performance. Upgrading to a newer router model that supports the current 802.11ax WiFi 6 standard with MU-MIMO and OFDMA technology will provide faster network speeds and wider coverage. Choose a higher-end router if you have 40-50 devices.
Poor Placement
Where you place the wireless router in your home matters. Try repositioning it to a central spot at a height, away from appliances that could block signals. Avoid putting it in a metal cabinet or cramped shelves. Placing it near windows can also weaken signals. WiFi signal strength reduces with distance and obstacles. Look to move the router for stronger signal in dead zones.
Old Firmware
Check if your router has any pending firmware updates from the manufacturer that can be downloaded and installed. Firmware updates improve performance by fixing bugs and adding optimizations. Outdated firmware could be the culprit behind a slow wireless router. Updating to the latest firmware improves speed and security.
Too Many Connected Devices
The more devices simultaneously connected to your router, the slower it will perform, as the bandwidth gets divided. Note the maximum number of devices your router can efficiently handle and try not exceed that limit. For a large home with 30+ devices, upgrade to a higher-end router with strong processor and more antennas to manage the demand. Limit the number of guests leeching your WiFi as well.
Interference from Other Networks
Nearby WiFi networks from your neighbours can cause channel interference and impact your wireless network speed if configured on the same channel as yours. Download a WiFi analyzer app to check which channels are congested. Optimize your router's 2.4GHz and 5GHz channel settings to avoid crowded channels prone to interference. Maintain adequate channel separation.
Heavy Usage Habits
When you have too many users on the network streaming videos, playing online games, downloading software updates simultaneously, it creates a bandwidth bottleneck that slows down your router. Limit bandwidth-heavy downloads to non-peak times. Check router admin console to view current bandwidth usage and implement QoS rules to allocate bandwidth wisely.
Outdated Modem
An older modem paired with your router can also hinder your internet speeds. Contact your ISP to check compatibility of your modem with your internet package and see if a replacement or upgrade is needed. Use a DOCSIS 3.1 modem for gigabit plans. Connecting your router to a gigabit modem will lift bandwidth restrictions.
Weak WiFi Signal
If your router WiFi signal is weak in certain areas, devices in those spots will experience lag and buffering. Adjust your router's channel width, transmission power, antenna direction to optimize signal strength. Switch to the 5GHz band instead of congested 2.4GHz for better performance. Add WiFi range extenders to remove dead zones.
Excessive Connected Devices
The more devices concurrently accessing your router will lead to congestion and slow speeds. Audit and limit the number of connected devices. Prioritize bandwidth for important devices by configuring QoS settings and add bandwidth hungry ones to a separate guest network. Disable unused ethernet ports, USB ports functions to optimize router performance.
By troubleshooting and fixing the potential causes outlined above, you can boost your sluggish router's speed and enjoy faster internet access. Upgrade your router model or firmware, optimize the placement, settings and connected devices to improve network performance. Contact your ISP if issues persist for further troubleshooting. With an optimized router, you will no longer have to suffer through slow internet speeds.
