You can take iwlwifi-7260-ucode-22.1.7.0.tgz or iwlwifi-7260-ucode-22.15.8.0.tgz. I used the latter firmware version with pretty much the same result. Attached you'll find complete (iwlwifi-related) dmesg. BTW, after these dumps the controller successfully connected to 2.4GHz network. --- dmesg --- Intel(R) Wireless WiFi driver for Linux, in-tree: Copyright(c) 2003-2013 Intel Corporation iwlwifi 0000:01:00.0: irq 62 for MSI/MSI-X iwlwifi 0000:01:00.0: loaded firmware version 22.15.8.0 op_mode iwlmvm iwlwifi 0000:01:00.0: Detected Intel(R) Wireless N 7260, REV=0x144 iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' --- snip --- iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S iwlwifi 0000:01:00.0: Microcode SW error detected.
