Describe Wi-Fi connectivity troubleshooting.

[bob]

You check the router lights right away. They show if power flows okay. I reboot it next because glitches happen fast. You move your laptop closer to test signal strength. Walls often block waves without warning. Interference from phones messes things up too. I fiddle with antenna angles sometimes.
You scan for nearby networks next. They crowd channels and cause drops. I switch the router channel manually in settings. Your device forgets passwords after updates hit. Reconnect manually to force a fresh link. Drivers get outdated and create hiccups. I update them through device manager tools.
Power cycles on the modem clear IP snags. You release and renew addresses via commands. But that fails when DNS servers act weird. I ping the gateway to spot breaks. Cables loosen over time from handling. You swap them out to rule out faults. Heat builds up and slows everything down.
Antenna positions change reception in odd ways. I test different spots around the room. Your firewall rules block access randomly. Adjust them to allow WiFi traffic. Overlapping signals from neighbors create chaos. I use apps to scan for quiet bands. Battery savers throttle connections on laptops. Disable those features during checks.
