The wireless option, which has been present in all recent releases of the Fedora Workstation installer, is missing from the latest Network Install image: Fedora-Workstation-netinst-x86_64-25-1.3.iso Normally, after clicking on the Network section of the Fedora Network Install setup, you would get both wired and wireless options. The wireless option is now absent. If this is intentional then I think it's a mistake. If not then it's a bug that should be fixed ASAP.
Update: ==> Works on HP ProBook 4430s, with Qualcomm Atheros Ar9285 Wireless Network Adapter (PCI-Express) ==> Fails to detect wireless adapter on Lenovo T400, with Intel Ultimate N Wifi Link 5300 Both are detected by the Fedora 23 installer.
The Intel Ultimate N Wifi Link 5300 Adapter is also supported on the following: Fedora 25 Live: Fedora-Workstation-Live-x86_64-25-1.3.iso Fedora 24 Network Install: Fedora-Workstation-netinst-x86_64-24-1.2.iso Apparently, support was omitted only in the Fedora 25 Network Install image.
Indeed, the firmware files for Intel wireless devices in /lib/firmware only include iwlwifi-100-5.ucode iwlwifi-105-6.ucode iwlwifi-2030-6.ucode iwlwifi-3160-10.ucode iwlwifi-3160-12.ucode iwlwifi-3160-13.ucode iwlwifi-3160-16.ucode iwlwifi-3160-17.ucode iwlwifi-3160-7.ucode iwlwifi-3160-8.ucode iwlwifi-3160-9.ucode iwlwifi-3168-21.ucode iwlwifi-3168-22.ucode iwlwifi-3945-2.ucode whereas Fedora 25 live systems and installed systems also include the range iwlwifi-4965-2.ucode .. iwlwifi-5000-1.ucode iwlwifi-5000-2.ucode iwlwifi-5000-5.ucode .. iwlwifi-8265-22.ucode.
