Computer thinks brother printer is off, but it is on.

How is it connected?
Network? USB?
Could someone have moved the USB port?
Unplugged the connection?
If networked, can you browse to the configuration page of the printer?

NW wifi connected, no, no, yes

Have you tried with a new user profile?

You might have to uninstall/reinstall the printer. Could be bad driver... Or lost connection...

I mean sorry, it's a local printer on wifi here at HOME, sorry

I hate reinstalling this printer.... That's why Im looking for any ideas... but I may just have to do it.  Oooooh no.  I made a change on the router recently... Is there a way to change settings in the wifi on the printer w/o reinstalling?

Is there a way to change settings in the wifi on the printer w/o reinstalling?

when you setup the wifi, it will tell you to press the button on the router that you can hold down for the printer to talk to it and should reconnect to the network

Can you ping the IP of the printer?
Is SNMP still enabled on the printer?
Check properties of the printer and see if it using SNMP polling to check whether the printer is connected/available.

Is the IP on the printer static?
Does the driver setup use a BR reference or is directed to an IP.

You should be able to print out the printer configuration page from the device... this will answer a number of the above questions, especially regarding IP configuration which will then allow for additional troubleshooting to help get your issue resolved

ok let me see if I can find that in the menu

dang these menus!

Is there a way to open the wifi config tool and "reconnect" the printer manually?

Is it network connected or local?
You said local earlier which means USB...
The easiest way is to remove printer which will leave the driver.
Then add it back... 2 minutes and fairly painless...

Are you still using an Android phone? Read the link below and check whether your printer is still connected to your wifi network and install its Android app to do a test print.

I dont think the printer's still connected.  I had to install a new router.  I used the same ssid, but it's a different router altogether.

the Android app doesn't see the printer

Read Page 31 to 33 of the attached Network user guide to connect your printer to your new router.

The obvious question, are you on the same wifi connection as the printer?

Everything except the printer's on the same wifi router, yes.  I just have to figure out how to readd the printer back to the NW

Jackie Man I've tried those steps in the past (and again today) and got the same error, "No Access Point" due to modern routers not having this aoss technology.  Not sure why but I've never had a router w/ aoss in it.  My printer is about 8 yrs old I think so not too bad.

Is it network connected or local? It's on my local NW and it's a wireless printer
You said local earlier which means USB... NA
The easiest way is to remove printer which will leave the driver. What does this mean?
Then add it back... 2 minutes and fairly painless...  Removing the printer means removing the entire driver pkg which is what Im trying to avoid b/c that's a lot of work

an eight year old printer might not have all the options for the wireless.
what is the parameters on the wifi WPA/WPA2 AES/TKIP? etc.

what flexibility do you have on the 2.5GHz side to make sure it backwards supports the wifi on the printer i.e. have wpa/wpa2 operating mode.

Did it work before and what changed when it stopped?

I replaced the router

check the wifi security settings and make sure the choices you made are supported by the older printer.

The printer does it indicate that it is connected to the wifi?

Which operating mode wifi supports, does it match the supported 802.11g,n,ac,ax
wpa/wpa2 did you maintain the same network or changed.
newer could have several wifi SSIDs such that you can have the one that works for the printer and the newer version for everything else while at the same time configuring them to access the same network, separate networks.

The issue with separate segments, broadcasts do not cross boundaries.
so a driver install that is based on detecting the printer based on the MAC address will not work, you would need to explicitly setup the port to the IP of the printer in the new setup.
while at the same time configuring the router to allow traffic from one network segment to access the other.

did the old router die, or did you replace it for age/speed ...

Still have access to the old router to check on settings/configuration?

where would you need to change those settings? I don't have the old router anymore

what model is the router?

Does the new router have the same wifi settings in terms of passphrase,
Or did you have  to reconfigure all devices?

In the wifi settings look at the 2.5ghz band to see what it requires.

Does your new router support WPS?

Under printer properties, check the ports tab. If using WSD port, try changing this to use TCP/IP address of the printer.

I was having similar issues for quite some time.  At some point one of the Windows updates cleared things up.  Are you up-to-date?

If you changed the router, even with the same SSID, the printer probably got a different ip address. At a minimum you probably need to connect to the printers SSID and re connect it, or at least reset it...

Brother uses a special mechanism for the printer driver that discovers the printer no matter the IP it has. the issue, however, will depend whether the printer is in the same segment as the device looking for it.
on a phone, however, you may have to rescan the network within the app to redetect it.

Well shucks..........I spent an hour on the chat w/Brother today and walked thru the manual adding the printer and it just wont add.  They don't know why.  It says successful, but I cant ping it.  So I had to get the 15' usb printer cable and reinstall the entire suite again.  :(

As a final check, I would try factory resetting the printer, re-connect it to the router via Wi-Fi, and reboot router, printer and PC - and then check if printer can then be pinged. That procedure worked for me with a similar Brother printer with the same problems.  Good luck.

Mike, oh I don't think I want to take the chance that I'd have to re-do all that work.  Im really disappointed in Brother's software.  I thought they would have done a much better job with their drivers.

Brother's wifi setup is best when the device is connected via USB and the wifi information is pushed to it.

The issue is to confirm whether the wifi supported option by the printer is what the setup on the new router.
The newer router might be an 802.11ac or ax and is set to the newer 802.11n and newer as an example using a more secure WPA2 AES
but the wifi on the printer might only go to WPA

....

or the wifi is setup hidden, not to broadcast the ssid ...

Also I have found that a SSID is case sensitive if you want systems to connect seamlessly...

It only takes wpa2aes yes.

You could rerun the connect portion of brother to configure the wifi parameters and set a static ip on the existing router by reservation, MAC address to ip mapping.

How?

do you have the bradmin tools installed?
You could under tools run the diagnosis for connection

You could rerun the installer and reconfigure

no idea what any of that is

probably brother admin tools

re-download the install if you do not have it still.
https://support.brother.com/g/b/downloadtop.aspx?c=us&lang=en&prod=mfc9325cw_us_as

Run the install, configure the network/wifi on the printer while it is still connected via USB.

I am going that you would prefer it to be on the wifi versus tethered by a wire....  
you can have USB and network drivers so long as you designate which is the default based on which option you choose.

Can you share the brand and model number of your new router?

Linksys Velop AC1300 Dual-Band Mesh Wi-Fi 5 System White WHW0101 - Best Buy 

Arnold, I worked with Brother on the 16th and finally got the printer connected.  I really wanted to use the printer's menu but for some reason, that wont work for me so I had to reinstall the whole suite with the usb cable....

Your printer only supports 802.11b/g networks
https://download.brother.com/welcome/doc002892/cv_mfc9125cn_eng_net.pdf

you have to be able to add one wifi ssid that is based on the 802.11G for the printer to connect to..
The problem it seems the linksys lacks that option. it only supports AC and N.

perhaps you can look at it this way; you got all you could from this printer, and it is time for a newer one?
