Public bug reported:
Hi,
I have a Sony Vaio Pro 11 which has a intel 7260 wifi chip. I've had
nothing but trouble with it (and from reading forums, I'm not alone). I
file this bug to help fix issues.
My findings with recent kernels: laptop has Ubuntu Vivid installed,
which comes with the 3.18 kernel and 23.11.10 firmware. With the -10
firmware, often the wifi doesn't even associate with the access point,
while all other devices in the house can. When it does connect, the
speed is fast for about 1 second (around 10 MB/s), en then drops to
20-60 kbps, or loses connection altogether. With self-compiled 3.19-rc6
(with latest iwlwifi-fixes merged) it's the same. I tried the 23.12.10
firmware, but it is the same.
When I switch to the 25.228.9 firmware, it is much better, however,
speed still drops every now and then, but much less than with the -10
firmware. Kernel version doesn't seem to matter much, firmware version
seems to drive all variability.
This problem is for both bands 2.4 GHz and 5 GHz.
I can provide all debugging info you request. I will provide the minimum
logging tonight when I get home.
