If your Wi‑Fi is slow or dropping out, changing the WiFi channel can help.
What is a WiFi channel?
Think of WiFi like lanes on a motorway:
- Each channel = a lane
- Your router and nearby routers all share the same “road” (WiFi spectrum)
If too many devices use the same lane → traffic builds up
Why changing the channel helps
Less interference from neighbours
- In busy areas (flats, streets), many routers sit on the same channel
- This causes:
- Slower speeds
- Dropouts
- Unstable connections
Switching channel = moving to a quieter lane
Faster and more stable speeds
- Less congestion = cleaner signal
- Your device doesn’t have to “wait its turn” to send data
Result:
- Better download/upload speeds
- Smoother streaming and calls
Improved connection reliability
- Interference can cause:
- Random disconnections
- Buffering
- Devices struggling to stay connected
A better channel reduces packet loss and retries
How to change wireless channels on your Heights 6766 Wi-Fi 7 Router
Log in to your router userface - (how to)
Go to the Wireless tab
Click the ⚙️ Settings icon
Find 2.4Ghz Channel (this will be defaulted on auto)
There are 13 channels to choose from within the 2.4Ghz spectrum we normally advise channels 1-6-11 are a good choice as these are none overlapping channels.
Once you have selected a channel - click save. This will disconnect your wireless devices for around 30 seconds; they will auto connect after the change.
Now select the 5Gz
Repeat the same process, the 5Ghz spectrum has 161 channels, we would recommend channels 36-48
