A few months ago I replaced my Z1 with an MR33 in my home office. Ever since then the range has been a problem for the only iPhone 11 in the house. It's confusing because there are other older iPhones in the house as well that are not having the same problem. The iPhone 11 worked with the Z1 just fine, and it does not have a problem on other wireless networks. Anyone else having a problem with iPhone 11s on MR WLANs?
