Sony VAIO – wlan firmware update 23.10.10.0

Just a quick not for those using Sony VAIO on recent kernels: There is a new firmware version out there: 23.10.10.0

sony-wifi

Reading through my dmesg log I found

iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-7260-10.ucode failed with error -2
iwlwifi 0000:01:00.0: loaded firmware version 23.214.9.0 op_mode iwlmvm
iwlwifi 0000:01:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144

which made me go to the linux firmware git repository, and indeed, in this commit “iwlwifi: add new firmware for 3160 / 7260 / 7265 / 7265D” a new firmware was added. After downloading the file iwlwifi-7260-10.ucode and putting it into /lib/firmware and rebooting into a recent kernel (in my case 3.18.0-rc7), I get the following lines in my log

iwlwifi 0000:01:00.0: loaded firmware version 23.10.10.0 op_mode iwlmvm
iwlwifi 0000:01:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144

Having had many problems with WiFi on Sony, I always hope that new firmwares and new kernels improve the situation. Let us see.

    New firmware + kernel 3.18 makes my wifi work veeeeery slow and lossing most of packets.

    Kernel 3.16 + new firmware works perfectly, but wifi range is very reduced.

    What about you?

    • Hmm I don’t see this behaviour, but I also see a different firmware loaded:

      [    4.048378] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002)
      [    4.102417] iwlwifi 0000:01:00.0: loaded firmware version 23.10.10.0 op_mode iwlmvm
      [    4.126373] iwlwifi 0000:01:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144
      [    4.127969] iwlwifi 0000:01:00.0: L1 Disabled - LTR Enabled
      

      My guesses are two:

      • either the older kernels cannot load or cannot use the newer firmware
      • router configuration is not optimal

      But it is hard to say, just that I don’t see these problems you mentioning.
