Poor Link Quality - Ubuntu 14.04 #81

Closed echosalik closed 9 years ago

echosalik commented 9 years ago

I have installed the drivers but the signals are unstable. They range from 1 point to none. When I ping the router, the signals increase uptill two points. I have another wifi device which gets full signals from the same place. Is it something related to the driver? I installed the latest commited version.

I would love to help out in debugging and stuff.

EDIT: I installed rtlwifi_new, after that the signals increase on use and go back to one point. Is this something power related?

lwfinger commented 9 years ago

As rtlwifi_new is for PCIe devices (except for RTL8192CU), installing it would make no difference for the USB-device RTL8188EU.

The branch v4.1.8_9499 has a newer version of the driver that is supposed to increase the sensitivity of the device. If that turns out to be the case, you could help by identifying the criticat difference between this code, and what is in the kernel or the master branch.

OK. Leme download that source. I downloaded the master branch. I'ld love to contribute.

echosalik commented 9 years ago

OK. I downloaded and installed the newer drivers, but my problem persists. Signals are still fluctuating. I downloaded your branch by checkout. Is there a way to know if the drivers are updated? Plus do I need to reboot?

Regards

lwfinger commented 9 years ago

If you unloaded the old driver, and reloaded the new one, then you have the new one. A reboot may not help as the kernel version is r8188eu.ko, and this repo produces 8188eu.ko. The lsmod command will tell which you have.

echosalik commented 9 years ago

lsmod | grep 8188 gave me this:

Module                Size         Used by
8188eu                755009        0 
r8188eu               814658        0

The device is plugged in but why are this is not being used? Plus this is my first time with Linux drivers, so how can I unload the older driver?

EDIT: WOW I disabled the module r8188eu and the signals are way better! Like the way they should be. :+1: Now I would like to help out as I can see the results. Tell me what you need from me.

Solved by using v4.1.8_9499
