Trouble connecting WIFI to Brother laser printer

[Randalls]

Per recommendations on the MRF I bought a Brother Mono Laser printer (HLL2390DW) last year and it has done a good job. Last week the WIFI printing has now gone missing. Drug out the original instructions and tried to reconnect and says it can not link. I double check the PW on the Xfinity router and the router sees all my devices except the Brother printer. I did a reset.

I originally set up the WIFI from an iPad and it worked with all my devices (2 iPads, 2 iPhones). Could updating to to latest iOS affected the printer?

I am trying to connect to the 2.5 ghz signal as it states it will not work on the 5 ghz signal. It sees the network but when I enter the PW it fails.

I rebooted the router and entered the PW through the link on the printer and fails every time it tries to connect to the WLAN. I also tried linking WIFI through my laptop running 10.13.6. It sees the 2.5 ghz. Same difference.

Any thoughts or advice much appreciated

make sure you connect to the 2.4 GHz, not 2.5

Now seriously, WiFi was rock solid on older Brother printers but many new models had issues in my very limited experience and also reading here on the forum.

Use an ethernet cable if possible.

My Brother color had issues with my wifi. I hooked it up to USB. Then there was a firmware upgrade and “poof”. It started working again.

OK, I will check on the firmware. Thanks

If it's a recent Xfinity modem/router, it may be providing both 2.4GHz and 5GHz WiFi using the same network name.

With this type of setup, sometimes it's necessary to disable the 5GHz radio on the router before a fussy device will connect to the 2.4GHz radio.

My Canon wacked out between printings just yesterday.

Could not find. Did the settings thing on the printer and still the computers in the house could not print to it.

Hooked up the USB cable and did a test print and rechecked the Ip settings and then pulled the cable.

WiFi works on all computers again.

Why Ask Why!

Yeah well checked router, checked names and separation of 2.4 and 5.0 ghz plus PWs. Reset, rebooted, sees the 2.4 signal but still fails to connect. Checked firmware. Going to use the USB to print from the laptop and trash Brother on the inter webs. So it goes. It isn’t that heavy, it’s my Brother
