Install from livecd crashed, wireless-related

[laptoper]

I've selected Wi-Fi network, entered password and connected, but on the next step, Software, the download updates option was still grey, so I returned back and connected to the network again. After some time going here and there I remember noticing and clicking something red in the place of the check mark in the header, then the download updates option became enabled but the installer shortly crashed.
