How to install Netem on a TP-Link TL-WR1043ND router with OpenWRT

To use Netem we need to install traffic control (tc).
To do this, we need install the last OpenWRT version (Chaos Chalmer). I tested before on Attitude Adjustment (a previous version) and I couldn't install on it.
To install the last version go to this page and choice your branch (stable or trunk).




















After install the factory and upgrade binary, run the following commands on your router console (throught ssh):

opkg update
opkg install tc iptables-mod-ipopt kmod-sched kmod-netem

A typical netem example is:

tc qdisc change dev eth0 root netem delay 10ms
RTNETLINK answers: No such file or directory

Remember, load netem first:

insmod sch_netem

If you have the same problem, run netem with this format:

tc qdisc add dev eth0 root handle 1:1 netem delay 10ms

Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
