Three channels, no overlap Gavin Phillips explains that the 2.4GHz band holds 83.5MHz of usable spectrum cut into 11 channels spaced 5MHz apart while each channel is about 22MHz wide, so only 1, 6, and 11 avoid stepping on each other: run a Wi-Fi analyzer in the evening when the building is busiest, pick the quietest of the three in your router's settings instead of leaving it on automatic, move whatever devices you can to 5GHz or 6GHz, and rescan now and then, because in a dense area you can still end up sharing a channel.

Six switches and shortcuts Pankil Shah updates every Winget-installed program at once by running winget upgrade -all in Command Prompt, turns on Settings, System, Advanced, End task so a frozen window can be closed straight from the taskbar, opens unknown software inside Windows Sandbox where everything is deleted on exit, mirrors an Android screen through Phone Link, remaps three and four finger touchpad gestures, and keeps Win+V clipboard history and Win+. emoji within reach; two limits are worth knowing, since Sandbox needs Windows 11 Pro and the Winget command leaves Microsoft Store apps alone.

Look before you drive Parth Shah taps the map icon on the Google Maps home screen, chooses Traffic under Map details, and reads the color-coded roads around the trip, spotting the red and dark red stretches before navigation begins rather than trusting a single estimated arrival time, then taps the three dot menu after entering directions to set a departure or arrival time and see how the drive should look later; he is honest that the habit pays best on routes you already know, because seeing the jam only helps if you know the way around it.
