Printer unable to find SSID

[Elcerrito1]

For the last couple of years my “LaserJet 100 Color MFP M175nw” was successfully connected via WiFi. After reorganizing my WiFi last week the printer won’t connect to the wireless network again. Though I am able to connect it via USB and LAN it simply won’t find any SSID. I also tried WPS, but also no success here.

While connected via LAN the Browser configuration Window/ Section 'Networking/Wireless Configuration' shows the available SSIDs incl. signal strength. Also Wireless Network Configuration shows that Wireless function is turnend on.

Anyone can solve the issue? Thank you very much.

What does this mean what changes you have done?

[Elcerrito1]

Just renamed the SSID (now same name für both 2.4 and 5 GHz). everything works finde except the printer

And yes, I have temporarily undone the changes, but no success

Restore wireless network settings to default, and use the wireless network setup wizard to connect the printer.

Does the printer see any other wireless networks available ( if any)

What wizard do you mean, HP Easy Start for MacOS?

I restored the printers network setup to default - as I did many times before. BTW since by default, "wireless" is turned off, I assume the printer could not be found w/o switching it to "on". Anyways I gave it a try... but no matter if turned off or on, no wireless network can be found.

In the router wireless settings "allowed all new devices" is enabled and all other devises are able to connect to the WiFi.

Hi,

Please make sure that there is no USB cable connected to your printer, from the Setup Menu select Network Setup, select Restore Defaults and confirm any prompt. then restart the printer.

Ensure your Mac is connected to your network wirelessly, if it is connected with ethernet temporarily unplug the cable for the printer wireless reconfiguration, then follow HP Easy Start and follow the steps on screen to connect the printer to your wireless network, then check for any difference:

As soon as HP Easy start prompts to install HP Smart, close HP Easy Start and press the Skip to Software Download button, then follow the steps on screen to complete the installation and check for any difference.

If you are not offered with any option to join a wireless network, I suggest setting a unique SSID for the 2.4GHz connection and ensure your computer is connected to the 2.4GHz operations, as if your computer is connected to the 5GHz band it is possible that no wireless configuration option would appear, as the printer supports a 2.4GHz operations only.

- Network Setup restored to default and printer restarted 

- Setup WiFi w/ unique SSID and 2.4 GHz band only

- Mac connected to WiFi 2.4 GHz, no ethernet cable plugged in

- Start "HP Easy Start" -> No device found!

Can you see the blue wireless light blinking once waking up the printer from sleep or is it off?

When you click the wireless icon on your Mac and select to Join Other Network, can you see a nearby SSID including HP-Setup in its name?

[Elcerrito1]

The blue wireless light is blinking continuously when wireless mode in the network setup menu is turned on. So when waking up the printer from sleep mode it continues to flash.

When wireless mode in the network setup menu is turned off the blue wireless light is not blinking at all but it flashes once when waking up the printer from sleep mode.

I can see a SSID named "HP-Print-1c-LaserJet100" on my Mac (of course only if wireless is on in the network setup menu) but none including "HP-Setup".

Please restore the network settings once again and confirm any prompt, them restart the printer and ensure the wireless light blinking so you should see now an HP-Setup network, then follow HP Easy Start to reconfigure the wireless connection for the printer.

If the same persists, please print and include a picture of a wireless test report, this can be printed from the Network Settings menu within its Setup menu, then select Wireless Settings and select Run Network Test.
