Sorry I don't understand your last sentence...

Since my router is not 11AC, should I use the command to disable the 11N however?

11n_disable=8 doesn't disable anything it actually enables some functionality, 11n_disable=1 does disable 11N but has fixed issues in the past

I'll try with this for one week first

Code: Select all

echo "options iwlwifi 11n_disable=8" | sudo tee /etc/modprobe.d/iwlopt.conf

With the 11n_disable=8 I get disconnected twice in the last two days. Now I'll try the 11n_disable=1 and let you know in a week.

I do set the brightness pretty low (it's now on 20%) but this laptop is HELLA BRIGHT! With 20% I get the same brightness I got when I was at 80% with my previous laptop.
WTH!

C'mon, from 4 hours to 9 hours is more than double, I can't believe it is only a matter of brightness...

I've never had more than 4.30 hours... and the last 30 min is while using the laptop in super saving mode that is with CPU fix at 500Mhz and is kind of unusable.

So what's the secret?
The secret, as far as I can tell, is using TLP (though screen brightness is dramatic, as screen backlight is the greatest power consumer according to powertop. On 65% you will get significantly less than on 20%). TLP is a service that turns on several power saving options when you work on battery. Here's a PPA for TLP: https://launchpad.net/~linrunner/+archive/ubuntu/tlp

There is another thing that may play a role. There are several versions of UX305. My version has the Core m-5y10c processor and the 1080p screen. The stronger processors and the Qhd screen are probably big power consumers, so if you got them that might be part of the story.

I have TLP installed already. But actually I can't control the CPU as I want. I'm trying to set the min CPU at 800Mhz when low on battery, but when the computer hits the 10% battery, the CPU get stuck at 500Mhz, and it is impossible to use the computer as everything get slow.
My version is the Core m-5y70 with 1920x1080p display. Do you think that this processor is consuming double power as the smaller one?

The next command enables aggressive tx and can increase upload/download speed

Code: Select all

JeremyB, I tried the 11n_disable=1 and get disconnected after 15 minutes of uptime... :(

Just to confirm that with the 4.2 kernel I am no longer getting the corrupted fonts when resuming from suspension, which is nice.

I don't care enough about the missing function keys to bother using a workaround, would be interested to know if they work in the latest version of Ubuntu. :)

Can you disable TLP control for the wifi?

There are daily builds of Ubuntu 16.04 that you can download but it likely still has bugs

It is already disabled. However, yesterday no interruptions, let's see today if it is working :)

Just to comfirm you the 11n_disable=1 is not solving the disconnection problem :(

[quote="JeremyB"][/quote]

Hey JeremyB, I really don't know what to do anymore. I keep on getting disconnected, and what I noticed is that when I get disconnected, I see all the other WIFI around the house, but not mine. So I have to restart the wifi and immediately then I see my router again.
What else can I do?

Code: Select all

lshw -c net
There might be newer firmware that will fix the issue and you could check

Code: Select all

iwlist scan | egrep -i 'ssid|chan|quality|cipher'
Look to see if your wifi is on a channel with a lot more access points and hopefully it shows cipher as CCMP and not TKIP

You could download https://wireless.wiki.kernel.org/_media ... 2414.0.tgz

Extract it and copy the iwlwifi-7265-16.ucode to /lib/firmware/iwlwifi-7265-15.ucode

The 4.2 kernel can't use the 16 version as it is and it might work if renamed

so I have to copy the 16 and then rename it as 15?
