    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
    Connection: Active
    MAC Address : ......... 71:22
    SSID; ASUS (that's right - my network)
    Communication Mode: Infrastructure
    Channel: 10
    Encryption: AES
    WEB key Length: Inactive
    Authentication: WPA2-PSK
    Signal Strength: 100%
    e.t.c
    Unfortunately, the router menu (client status) does not include this device.
    I tried several times to connect the printer to the network, restart the router and the printer, turn off the Firewall - no effect.
    Any ideas please.

    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.

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

    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?

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

    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.

    Added after 1 [hours] 7 [minutes]:

    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?

    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.

    I don't know if that is possible. I can set one specific channel.

    maybe something to do with "channel band"?

    Channel band on 20MHz and channel 6 and try.

    @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 :D

    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.

    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.

    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.

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

    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.

    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.

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

Topic summary

The discussion revolves around an issue where a user is unable to connect a CANON iP7250 WiFi printer to a new ASUS DSL-N14U router despite the printer showing correct network settings. Initial troubleshooting steps included connecting the printer via USB to a computer, which allowed the router to recognize it temporarily. However, subsequent attempts to connect the printer over WiFi failed, even after resetting the printer's network settings and adjusting router configurations, such as changing broadcasting channels. Eventually, the printer started working with the router, possibly due to a firmware update or network memory reset. The conversation highlights various troubleshooting methods, including driver reinstallation, channel adjustments, and the importance of ensuring compatibility with router settings.
