My Brother HL-6180DWT printer not connecting to wireless network?

Answer 1

My solution was to:
1) Use the default of "Obtain DNS server address automatically" for the network interface card TCP/IPv4 settings
2) Go into the Device Manager and under Imaging, delete all copies of the Brother printer. I happened to have four of them (that could be a contributor to my problem). While deleting those devices, I also uninstalled the printer driver.
3) Remove all copies of the Brother printer and faxes from Devices and Printers
4) Restart the PC
5) Then, reinstall the Brother printer software and follow the instructions to restart the PC.
