MX922 goes to sleep and loses WiFi connection

[bruceadler]

I have a new MX922 that replaced a dead MX870. The old MX870 worked fine until it died but this new MX922 doesn't work correctly on my WiFi network. And the only thing that's changed is the printer (all the other PCs and printers and the Wifi router are the same as before and still work just fine). The new MX922 goes to sleep and can't be woken up from any PC on my network (to print or scan). The old MX870 NEVER had a problem on this WiFI network and NEVER had a problem with sleep mode. I also still have two MX890s that still work just fine. When the MX922 stops responding to pings, the blue WiFi logo on the front is on, and the Network Configuration Page always says "Connection Active" (but it's not).  Any suggestions that it's my router or my PC driver's fault is nonsense. It's clearly a MX922 WiFi bug which Canon needs to fix ASAP.

Over the past few weeks I've discovered that if the printer goes to sleep for an extended period it frequently "loses" it's WiFi connection and nothing I do from my PC will let me print to or scan from it. Basically it stops responding to pings (which tells me that its WiFi network connection is the issue). I usually discover the printer is offline line first thing Monday AM (after the office has been closed all weekend).

When the MX922 goes into a coma the only way I've found to wake it up is to either power-cycle it, or do go into the Device Settings menu and print out the current Network Configuration Page (it sometimes starts printing/scanning again when I exit out of the menus). AND sometimes after waking it up via the menu trick it operates very very slowly (like the Wifi connection is poor or congested) and I end up having to power cycle it to fix it. I shouldn't ever have to power cycle the printer just to wake it up (especially since it probably uses up some ink to recharge the print head each time it powers on).

Since I got it about 6 weeks ago, this printer has gone into a coma about once a week. Recently I tried disabling the Wireless DRX option and that seems to have made it worse. Since I disabled that option, It's gone into a coma 3 times in the past two days.

That makes some sense. A few days ago I bought an HP Laserjet and configured it for wireless. Same EXACT problem. I began to suspect my Mac. But maybe it’s never been the printer; it's the routers. Thanks Seratonin.

I'm not really sure your time was well spent with this message.  You might have better results, for yourself as well as for the rest of us, if you spoke with someone directly and demonstrate the respect for them that you would like for yourself.  Not everyone has the same level of expertise.

Linda - I may have replied twice to this, but the message is the same.  I do not understand your comment about my post - can you explain further?  Thanks.

It's possible I replied to the wrong person.  Sorry!

Thanks harrybuckman. Your fix cured a nagging problem I had with my MB2320 that would keep losing my wireless connection.

I've been following this thread briefly, having had this very problem on a friend's MX922, again and again.

When I leave, their printer is online and working, the next hour or day it is not.

I defined the static IP long ago, believing this would finally do it, but it had no lasting effect.

I have to agree with the analysis and conclusions of bruceadler throughtout this thread.

I defined a static IP for my wife's MX882, at about he same time I did that same chore for my friend's MX922.

The MX882 had occasional offline issues, but none since the static IP was  defined for that printer.

The MX922 seems unfixable, though I will try to find the "LAN drx" settings when I have my next chance.

Thanks to all who contributed to the discussion.

Did you set the ip address about the dynamic address range? I have never had a problem after doing this and it has been years.

Right! No other device in my network has the same problem. I have tried with static IP in the router and the printer, with no positive result. And if I try to ping  some devices in my network, everyone answers, exept my mg6250.

Static IP is not the solution. The don´t answer direct IP-ping from my ws.
