I changed to 2.4 GHz from 5GHz and it solved the issue with Brother MFC-L2700DW. I have UnityMedia connection in Germany and after changing the router and upgrading the speed I started facing this issue . I did reset my printer few times without help. Finally logged in to router and changed it to 2.4Ghz by disabling 5Ghz. Hope this helps.
