Why Does Wi-Fi Slow Down After a Router Update?
Before fixing the issue, it’s important to understand why your router update caused slow internet.
Firmware Bugs
A new firmware update can sometimes introduce bugs that interfere with performance.
Changed Default Settings
Updates often reset or alter your router’s settings, including channels, frequency bands, and QoS (Quality of Service) features.
Compatibility Issues
Your devices might not be fully compatible with the updated firmware, especially if they’re older.
Network Congestion

Guide to Fix Slow Wi-Fi After Router Update
Let’s go through proven solutions to get your internet back up to speed.
Restart Your Router and Devices
It may sound simple, but restarting your router and connected devices can refresh network settings and resolve temporary glitches.
Check Router Placement
Ensure your router is placed in a central location, away from thick walls, microwaves, and other interference-causing devices.
Switch Wi-Fi Channels
After an update, your router may switch to a crowded channel. Log into your router settings and manually select a less congested channel.
Update Network Drivers on Devices
Sometimes, your devices need updated network drivers to work smoothly with the router’s new firmware.
Reconfigure Router Settings
Check for changes in settings like:
- Frequency band: Ensure both 2.4GHz and 5GHz are enabled.
- QoS rules: Turn off bandwidth restrictions if they were reset.
- Security protocol: Use WPA3 or WPA2 for best performance.
Roll Back the Firmware (If Needed)
If the update caused major issues, check your router’s support page for the option to revert to the previous version.
Reset Router to Factory Defaults
As a last resort, reset the router. Reconfigure it from scratch, ensuring no corrupted settings remain.
Advanced Fixes for Persistent Slow Wi-Fi
If basic troubleshooting doesn’t help, try these advanced methods.
Change DNS Settings
Switching to Google DNS or Cloudflare DNS can improve browsing and download speeds.
Limit Connected Devices
Too many devices can hog bandwidth. Disconnect unused ones or prioritize important devices in router settings.
Upgrade Your Router
If your router is older, even updates won’t help much. Consider upgrading to a modern Wi-Fi 6 router.
Contact Your ISP
Sometimes, the issue isn’t with your router but with your internet provider. Services like Dhanote Internet Services offer reliable connections and can help troubleshoot further.
