System is a Lenovo T580 with Dual Band Wireless AC 8265 Attaching dmesg section where the wifi crashes Interesting lines: 529 [293336.199635] iwlwifi 0000:04:00.0: loaded firmware version 36.e91976c0.0 op_mode iwlmvm 530 [293336.199661] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8265, REV=0x230 531 [293336.261557] iwlwifi 0000:04:00.0: base HW address: 18:1d:ea:2d:5e:2e 540 [293340.092557] iwlwifi 0000:04:00.0: Microcode SW error detected.
