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
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:
My guesses are two:
But it is hard to say, just that I don’t see these problems you mentioning.
