How do you change the channel I’m on Channel 1
Channels wil automatically change. Only limitation is that country setting need to allow that channel.
So you might have to install crda and change the country for your wifi dongle.
dmesg will give you more details of which channels currently are allowed by the driver/country
Your router/access point tells your RPi’s WiFi adapter (and all the clients on your network) which channel to use - channel 1 indicates that you are on a 2.4GHz WLAN in which most countries in the world will allow channels 1 to 11, whereas f.e. Germany also utilizes channels 12 and 13.
If you want to change your channel, take a look at your routers’/access points’ settings at first.
My pi is the routers’/access point
D’oh…
For 2.4 GHz (802.11b/g/n) the generally accepted advice is to use only channels 1, 6 or 11. By all means choose a channel (from 1/6/11) that is less populated but don’t be tempted to go for something in between.
For example, if you choose channel 4 because you see that nobody else is using it, you’ll interfere with those operating on channels 1 and 6 and, just as importantly, you’ll be competing with twice as many people as if you’d chosen either 1 or 6.
See wireless networking - Is it better to use a crowded 2.4GHz Wi-Fi channel 1, 6, 11 or "unused" 3, 4, 8, or 9? - Super User for a more detailed explanation.
