MF634Cdw gets wifi unreachable in 2 minutes

My MF634Cdw gets unreachable through wifi in 2 minutes. Printer says it's connected and signal is good, but ping gets unreachable from other machines. If I go to the printer settings and do "Ping Command" to the other host, the printer gets reachable again. Once I do that, I can print without problem, but only for 2 minutes. After 2 minutes, it gets unreachable again. I have 240 minutes for auto sleep, and wifi energy save mode is disabled.

 

It has similar symptom since I purchased it 5 years ago, but at first it was only once in a while I had to reboot the printer. Now I have to go to the printer and do "Ping Command" every time. Even restarting the printer doesn't help anymore.

 

I suspect the wifi module is broken. Is the wifi module on MF634Cdw replaceable?

I ended up with connecting USB cable to the Linux machine and make it printer server. Scan and email still works though... it becomes online for a few minutes once it has an outgoing traffic.

Greetings,

Whatever is occurring, It's likely related to your network, hardware or settings and not the printer.

Start by telling us more about your wireless network.  What router brand/model are you using?  Did your ISP supply it, or is it something you purchased?

Is your wireless dual band.  Are you using the same SSID names for 2.4/5G networks?

Have you assigned a static IP to the printer?

What are the version and builds of the operating system(s) you are using?  Windows/Mac

I'm not under the impression your network adapter is faulty at this point.

Google Nest wifi, my own.

Same SSID for both 2.4/5G and can't separate

static IP

Multiple devices, Linux, Chromebook, Windows10, Android phones. All can't print once the symptom appears, and everything recover once I do "Ping Command" from printer.

 

I have over 30 wifi devices at home including many 2.4G only devices and only MF634Cdw has this behavior.
