ASUS DSL-N14U Router Not Detecting CANON iP7250 WiFi Printer Despite Correct Settings

Question

Hello. After replacing the router with a new ASUS DSL-N14U, I have a problem with the CANON iP7250 printer. This printer does not have a display but by holding down the button you can print a page with settings and according to this printout everything is OK. That is: Wireless LAN - Enadle...

I had the same problem with a Brother printer once. Do the setup with the USB cable connected.

To the computer.
Once the computer finds the printer via USB, it will be easier to connect via WiFi.

In total, you should do a network reset in the printer beforehand, because the connection settings with the previous router probably remain in memory.

APPROX. But USB connect to computer or router?

fido100 · Answer

of course I had read before, but I was only focused on connecting via WiFi. I'll plug in the USB cable and see.

fido100 · Answer

Yupe!! Works. After reinstalling the driver and connecting the USB cable, the router saw it and now everything is also working over WiFi. Thanks a lot!

Unfortunately, my joy was premature. Today the router does not see the printer's IP address again and I can't get it in any way. I messed with the USB cable, restarted the router, printer and nothing. I have reset the network settings on the printer to factory defaults, etc.
I've run out of ideas.
However, there may be something wrong with this output:

Change broadcasting channels to Asusue (1, 6). Can't you assign an IP to the printer?

AxelNext · Answer

Were you able to connect the printer to the router over Wi-Fi?

fido100 · Answer

Failed to. According to the printer (scan of the printout above), the connection is.
But in the router, this device is not in the list of connected clients.
Only once the printer showed up in the router right after installing it via the USB cable (according to your advice).

Now I'm at work, but after returning home I'll try to configure the printer again (assign it a fixed IP) and if that doesn't work, I'll change the broadcasting channel in the router.
I would suspect damage to the WiFi card in the printer, but it worked without any problems with the previous sagemcom fast 2704 router.

I called the CANON helpline and was advised to uninstall the printer drivers and reinstall.
Of course, I will do so, but can it have any effect on the WiFi connection between the router and the printer?

AxelNext · Answer

Turn off the work on channels 12 and 13 on the router because not every device can handle these channels. Very often the device does not see the 12th and 13th channel of the router and will not connect to it. I will write differently, the channels set on the router 12 and 13 disable SSID broadcasting.

And after that, restart the router, i.e. plug from the socket for several seconds.

Reinstalling the drivers is a good idea, but I'm betting on a problem with the above-mentioned channels.

fido100 · Answer

I don't know if that is possible. I can set one specific channel. maybe something to do with channel band?

AxelNext · Answer

What's under there? Extended channel ?

hermes-80 · Answer

Channel band on 20MHz and channel 6 and try.

AxelNext · Answer

@U.P. Relax :D @fido100 use the inSSIDer program and paste the screenshot on the forum, we will determine exactly how many MHz and which channel for today

fido100 · Answer

These are scans (for comparison) from the old router on which the printer works.

I'm letting go of the WiFi installation. I will install it with a USB cable straight to the router. I don't like it because it blocks my only USB port.

AxelNext · Answer

Your old router was set to work on the auto channel, but from what you can see it worked on channel 11, so set the Asus to channel 11, save and the printer should find the Asus SSID.

fido100 · Answer

Changing to channel 11 did nothing. For now, I let it go, and if I need a USB port on the router for flash memory, I will return to trying to install the printer via WiFi.
But if any of you come up with a brilliant idea, please write.

AxelNext · Answer

i.e. that the printer does not see any network? , no router (SSID) in range?

fido100 · Answer

One more time.
The printer does not have a display, so you cannot check what SSID networks it sees at the moment. It connects to the router as follows: hold down the blue network button until it starts flashing, then press WPS on the router, the printer LEDs (WIFi and power) flash for a moment and that's it. The network settings stored in it can be printed by holding down one of the buttons. The printer connects and works correctly with my old Sagemcom router. It seems to connect to the new Asus but Asus does not see it. I do not know if it is the fault of the printer that supposedly connects but is not connected, or the router that allows you to "see" but does not allow it to connect.

fido100 · Answer

I don't know how it happened, but it just started and works. Maybe the router's firmware has been updated? - Never mind. I am glad that I can free up the USB slot to which I plan to connect the flash drive.
We're closing.

AxelNext · Answer

It didn't update itself. Nothing is done by itself. Probably restarting the router or the printer remembered the network.
