The root cause might be difficult to point out (platform own radio noise/buggy firmware/etc) however one of the very first things to try, even if the power management has been disabled for the iwlwifi module, is to prevent the WiFi adapter PCIe link to go in power save mode.Computer: Acer Aspire 7730. Consequences might be network drop outs and/and severe slow downs even after the connection to the AP has been restored. This indicates that a severe error has been encountered by the WiFi adapter's micro-controller which led it to be reset. iwlwifi 0000:28:00.0: ieee80211 phy0: Hardware restart was requested iwlwifi 0000:28:00.0: Start IWL Error Log Dump: iwlwifi 0000:28:00.0: Microcode SW error detected.
