Why might you need to disable the wireless module?
There are several scenarios where active Wi-Fi module It becomes unnecessary or even detrimental to the stable operation of the equipment. Users often switch to a direct USB connection to ensure maximum data transfer speeds for large amounts of data or to scan documents in high resolution without the lag typical of wireless networks.
Another common reason is the need to eliminate radio interference. In offices or apartments with a large number of gadgets, every extra signal can create noise. By disabling Canon MG3640 By disconnecting from the network, you free up frequency band space.

- Press and hold the button
Wirelessuntil the power indicator lights up. - Without letting go
Wireless, press the buttonStoptwice. - Release both buttons.

| Indicator status | Meaning | Action |
|---|---|---|
| It's blue | The connection is active | A reset is required to disable it. |
| Flashing blue | Searching for network / Error | Check the router |
| It's glowing orange | Error or Direct mode | Attention required |
| It doesn't burn. | Wi-Fi is off | The goal has been achieved |
An orange light often indicates a problem. If the orange light turns on after you've tried to disable Wi-Fi, there may have been an error during the reset process. In this case, it's recommended to unplug the device for 10-15 seconds and then plug it back in.

In rare cases, only a full cyclic reboot helps: turn off, unplug the power cord, wait a minute, then turn it back on. This clears the buffer. RAM controller, where erroneous commands could have been recorded.
Frequently Asked Questions (FAQ)
Is it possible to completely turn off the Wi-Fi module physically?
It's impossible to physically disable the module inside the case without voiding the warranty and breaking the seals. However, a software reset of the network settings effectively disables its functionality, and it stops transmitting a signal and searching for networks.
Will the IP address reset after turning off Wi-Fi?
Yes, when you reset the network settings, the static IP address, if it was entered manually, will return to the default value (usually obtained automatically via DHCP), but since Wi-Fi is turned off, this setting will become irrelevant until the next time it is turned on.
Does turning off Wi-Fi affect USB printing speed?
No, it doesn't directly affect the printer. However, the absence of background network processes can theoretically reduce the load on the printer's processor, which in rare cases can positively impact print queue processing speed.
Do I need to reinstall drivers after disabling Wi-Fi?
If you're switching to a USB connection, the system may require you to install a driver specifically for the USB port, even if the network driver is already installed. This usually happens automatically.
