MFP 1202w - Won't connect to any wifi after trying to change network

[FearBiscuits]

I was able to set up my Neverstop Laser MFP 1202w when I first brought it home about 6 weeks ago. I connected it wirelessly to multiple computers, both Mac and Windows.

Yesterday, I tried changing it to a different wifi network, and now it won't connect to any of them. I opened up the printer's config page by using its IP address. I went to the Networking tab and then to Wireless Configuration. I selected the new network, entered the password, and clicked Apply. Even though I'm 100% sure I entered the password correctly, it just won't connect to that wifi network or any other.

As it's trying to connect to the wifi network, the wireless light blinks blue for 10-15 seconds, then goes to steady orange. There are no messages on the LCD screen. The Wireless Configuration page just refreshes itself and the status remains not connected.

I've tried everything I can think of...

1. Activating wifi setup mode by pressing and holding the wireless and cancel buttons before trying to set it up

2. Attempting the setup via a computer connected wirelessly to the same network

3. Attempting the setup from a computer directly connected to the printer via USB

4. Updating the firmware of the printer itself

5. Reset all the network settings to their factory defaults\

If anyone can make some suggestions, I would greatly appreciate it.

Thanks, but that doesn't help me. My printer just will not connect to any wifi network.
