Changing Channel on Laptop

[PaintedWolves]

I've switched the Channel on my mobile but the laptop speeds are consistently so much slower. How do I change Channel on the Laptop?

Assuming you mean the wifi channel, you can't change that on the devices, you have to change it on the router and the devices get it from there. If you mean you used the Vodafone app on your phone then that will change it on both the phone and laptop.

Wifi channels are set up on the router.  Once set, everything that accesses the wifi will be on that channel.  

You can only have a different channel for the laptop if you connect the laptop to a different wifi, like 5Ghz instead of 2.4 Ghz or maybe connect it to your guest wifi if you set one up and you configured it differently.
