The older wireless brother printers kind of were a PITA since they locked to a channel. If your accesspoint was able to change channels due to congestion the printer would not re-connect until the ap was back on the same channel or the printer was reconfigured. At least they fixed that in later updates/firmware. That made life a little hell for some of the printers deployed at remote sites a long time ago. Even then, They were still better and cheaper than everyone else so there is that... Either way, Unless Brother fucks up majorly they are what I use and have for about a decade now.
