Low WiFi signal on Bangho Notebook


Hey everyone. Just came back on Linux on my new Notebook. I'm on 19.1 Tessa, and the WiFi signal is really low (around 60%). I'm literally a few steps from my router. What can I do to improve it? :|

I heard there might be a problem with the drive and the antenna selection, but I have no idea how to fix it. Please help, since having a signal so weak makes my notebook unusable. Thanks in advanced for any help.

antenna is hardware, it is what picks up the signal, bad antenna, bad signal. The quantity of derogation then depends on the quality of the antenna, and how many are being used to pick up a signal in order to improve on the derogation.

bangho seems to be a rebranded argentinian laptop thingy.
i'm guessing, but something is telling me it could a rebranded CLEVO laptop.
please find that out, then edit your thread title. it will enable more people to help you.

here's a request for output for wifi problems:

Hey, thanks for answering. Sorry I took so long, been really busy at work.

I have tried the rfkill command, here is the output. PS: I have no idea how to know if it is a rebranded CLEVO (the pc is, indeed, a national argentinian laptop).

I have a different chipset, but it has connections for 2 antennae, but only 1 actual antennae. By default the driver selects the wrong one. But the driver has an ant_sel=# parameter to select the other one. Which greatly improves my signal strength, otherwise I was looking at 24/70 as the best quality / signal strength. You might check your modinfo for your module / driver for a similar option. Or wait six+ months for the driver to implement auto-selection, and hopefully it works correctly. Of course run something recent and update/upgrade or it doesn't matter when you're stuck in the past.

I cannot see anything obviously wrong here; no missing firmware etc.

by all means, try what the previous poster suggested.

but, a Quick Search (tm) revealed very interesting results, please look at ALL of them: the ubuntu-related, and the debian wiki entry (troubleshooting) esp.

Try this

Code:
sudo modprobe -r iwlwifi
sudo modprobe -v iwlwifi  ant_sel=2
If it doesn't help change ant_sel=2 to ant_sel=1.
If it works then can make it permenant by creating a /etc/modprobe.d/50-iwlfifi.config file with this in it
Code:
options iwlwifi ant_sel=2

# modinfo iwlwifi

It doesn't have ant_sel. But it does have power_level (1-5 default: 1) and antenna_coupling (default: 0 dB). No idea what, if anything, those things do.

Try 'sudo iwconfig wlan0' in a terminal. It should show if you're connected, and what the Quality is. It will be xx/70. post what it says.
