Re: MX922 goes to sleep and loses WiFi connection

My Canon MX922 menu does not look like that.

I hit WLAN setup then looked for 'other settings' and only saw 'Other setup options' which goes to 3 options: Standard, WPS, other setup.

Hit other set up goes to advanced setup

Hit that which shows router info only. No place to disable 

 

Am I looking in the wrong place?

Re: MX922 goes to sleep and loses WiFi connection

I finally gave up and solved the problem by connecting the printer to my router with an ethernet cable.  Saves a LOT of time and frustration.

Re: MX922 goes to sleep and loses WiFi connection

I seem to have solved my problem Canon Pixma MG3222.  I have two computers (both Windows 10) that I print from.  One is close enouth to the printer that I can connect with an USB cable.  After I did that, the wireless printer can print anytime even when the USB cabled printer is at sleep.  It's been several months now.

Re: MX922 goes to sleep and loses WiFi connection

spirestocks, I read your lenghty posts in the other thread. Two points:

 

1. your troubles initially configuring your MX922 (requiring you to config as usb printer, then wired printer, then wifi printer) don't seem directly relevant to the issue of the MX922 going to sleep and losing its wifi session. I've succesfully switched my MX922 between wired and wireless multiple times without doing a USB config, but I can accept that there are ways to so badly screw up Windows 10 and the MX922 that a USB config might me needed. I think those issues aren't related to the wifi/sleep issues. Also, your issues seem to be specific to WSD in Windows 8 or 10. People are reporting wifi/sleep issues on other Windows releases and other OSes. Regardless, people with the wifi/sleep issue have a *correctly* configured network connection to the MX922, and are able to use their MX922 continuously (for days at a time), up and until it goes to sleep for more than a few hours (or perhaps over the weekend in some cases).  

 

2. part of your lengthy posting in the other thread seems to say that you think assigning a static IP address and reserving it on the router solves the wifi/sleep problem. I know for certain that assigning a static IP doesn't fix the problem on my network. If my MX922 (with a static IP address) goes to sleep long enough it stops responding to the network and has to be power cycled to force it to re-establish its wifi connection. About the only thing assigning a static IP address will do is prevent wifi devices that join your wifi network from getting your MX922's dynamic IP address while the MX922 is asleep. But that can only happen if they join the wifi network after the MX922 has been asleep for longer than the DHCP server's reservation timeout. Setting your DHCP timeout to something like 7 days (assuming you use your printer at least once a week) should prevent this without having to assign a static IP address.

 

Regardless, if the MX922 is still connected to the wifi network, assigning its previously assigned dynamic IP address to a second device, or assigning the MX922 a different dynamic IP address, should NEVER happen.

 

A correctly designed wifi device should *NOT* require a static IP address. It should "keep alive" it's session with the wifi router and refresh it's IP reservation with the DHCP server as needed. The fact that the MX922 doesn't correctly manage its dynamic IP address with the DHCP server is just another symptom of it not keeping its wifi session active after it sleeps for an extended period. Wifi devices are supposed to know what the wifi session timeout period is and periodically wake up and keep the wifi session active by responding to status packets from the wifi router. Similarly they're also expected to as needed refresh their dynamic IP address reservation with the DHCP server (so that the DHCP server doesn't ever assign the MX922 a different IP address, or assign the MX922's IP address to another device). 

 

In other words, if the MX922 managed its wifi session correctly there would never be an problem with dynamic IP addresses because the MX922 would always be able to respond to the DHCP server's queries.

Re: MX922 goes to sleep and loses WiFi connection

bruceadler, Thanks so much for taking the time to respond.  Subsequent to my original post, during more troubleshooting, yes, the MX922 seems to not manage the connections very well; the question now is how to recover especially in the wireless mode, which seems to be the most difficult to resolve.  I am working on a step by step method to resolve, but in a nutshell, I put the printer via the touchscreen in the mode I want to resolve and reset the LAN settings. 

MENU>Setup>Device Settings>LAN settings>Reset LAN Settings

The advantage of knowing the reserve address/static ip address that the router is assigning to the printer MAC address allows someone, after the reset LAN settings, to go in manually and add the expected assigned ip address via the printer touchscreen, to include the subnet and then gateway (router) information via the following path:

MENU>Setup>Device Settings>LAN settings>Other settings>TCP/IP>IPv4>Select Yes>IP Address>Manual Setup

Once I know the printer has the expected, static/reserve address, I shut off the printer, and then shut off the router as well.  Then I turn on router and then printer and initiate a wireless connection via:

MENU>Setup>Device Settings>LAN settings>Wireless LAN setup. Sometimes it takes a couple recycles of power between the router and the printer, but by typing in the reserve ip address that is tied to the router, the printer has re-initiated connection with router everytime now.  Hence, as long as the latest Canon ports/drivers are installed for each method (USB,Wired, Wireless) people shouldn't have to worry about setup re-initialization because this sequence has now worked to resolve the issue. After the issue is resolved, I go the the address of the printer via the address bar, lets say, 192.168.1.250 and disable the ipv6 option, and the settings for the LAN DRX mode.  I also add a location for the printer.

MENU>Setup>Device Settings>LAN settings>Other settings>Wireless LAN DRX setting

MENU>Setup>Device Settings>LAN settings>Other settings>Wired LAN DRX setting

By resetting the LAN settings then manually adding expected TP/ICP settings reserved in router with MAC Address and then re-establishing a connection after power resets for both router and printer seems to resolve the issue.  Lets keep each other posted.  Thanks

Re: MX922 goes to sleep and loses WiFi connection

spirestocks,

 

you must be having a completely different network issue with your MX922 because the wifi/sleep problem on my MX922 has ALWAYS been fixed by simply power-cycling the MX922 (ie power it off, wait 30 seconds, then power it on)

Re: MX922 goes to sleep and loses WiFi connection

[ Edited ]

The underlying ongoing 4+ year MX 922 issue is the same.  After the sleep mode goes into effect, the cycling of power works if the DHCP address that was given to printer remains the same.  However, if the dynamically assigned address [in the interim] is given to another device, then the IP address shown on printer is no longer in sync with the previously, now, reassigned IP address that was originally given to printer and now is assigned to another device.  This is most apt to happen if current printer IP address is near the bottom (smaller ip address, such as 1.2/1.3) of the DHCP range.  When this happens, in my experience, there is no way to tell which new DHCP IP address the router is trying to re-assign to the printer because the printer is not recognized and does not show up on the router attached devices; because, the IP address showing on printer touch screen is now taken by another device.  That is where the complexity and diffculty arises, because recycling the printer power and/or the router doesn't solve the problem.  What I found is if you reset the LAN settings on the printer which clears the IP address in printer and disables the printer LAN connection, you then can select the Wireless mode on printer which assigns the SSID in printer to BJNPSETUP for wireless printer mode only.  At this point, you query the router with the Wired IP address Setup on printer.  However, this doesn't always resolve either, which is why I suggested having router address/assign or setup IP static address in router  associated with each (both modes/methods wired and wireless with separate IPs) of the printer MAC Addresses (unique for each mode: wired and wireless and ports will show by MAC Address the number that matches the method).  I select the last DHCP address in router range (192.168.1.254 current range on my NETGEAR) to wired mode and the second to last DHCP router range IP address to wireless mode/MAC address, then I know which IP address the router will try to assign to printer after sleep mode based on mode selected on print touch screen.  If the Wireless Setup doesn't work, I go into the printer TCP/IP settings and manually set the IP address on the printer that matches the router IP address for static/assigning address, that way, I know that the IP address on the printer will match the address that the router will select for printer modes that each have a different MAC Address for both wired and wireless method.  If I then recycle power to both the router and the printer, this usually will work without having to re-initiate the setup using the downloaded drivers.  If it doesn't re-initate, as mentioned before, I can re-install the drivers and during that process, I know that the IP address I had already manually set in the printer will now match the static IP address in router that I associated with MAC Address and this address will now show up in the next address option during the setup process with drivers (USB, wired, wireless mode).  This works everytime as long as the next button is selected after I choose next address.  What is confusing is that the top paragraph during driver setup process says that the printer was not detected even though the next address I see during drivers setup process matches what is on the printer and in the router and in the detected devices on router.  This will work after clicking on next button, but I still have to re-cycle power for printer and router and each time I do this another set of Canon printer driver ports is established/added.  To avoid having so many Canon drivers installed, I change the port name to match the IP address assigned in router.  I have to go through this process twice for both the wired and wireless modes after choosing each mode and making sure the mode on the printer is selected and the proper mode is prepared (wired: connected cable to router LAN).  If you do the wired method first in setup you have to make sure IP Address in printer is changed to reflect IP Address for Wireless when you go through that setup process.  If I have to go through installing the drivers, I make sure I delete all of the printer icons in the computer printer/device control panel associated with MX 922 printer ONLY and I delete the Canon ports also, noting, when I do see the new printer icon after driver setup process, I have to go in and change the port from WSD to the correct Canon port for desired mode (wired or wireless), which was just added during the driver setup process. If the printer DHCP IP address is ever reassigned, I hope this helps people to get the printer and router synchronized.

Re: MX922 goes to sleep and loses WiFi connection

Also look at the wired DRX setting. Set both to off.

Re: MX922 goes to sleep and loses WiFi connection

So, apparently, there is no answer to this issue.  Out of the box, this printer loses WiFi and won't print unless I reboot.  That's pretty poor.  I will give this printer and this forum a couple of weeks, then I will trash this printer and never buy another Canon anything.
