Pi 3 wlan

Thu Mar 17, 2016 11:58 am

Greetings!

After installing Raspbian on a new Pi3 I checked wlan0 for existing SSIDs.
A few were visible plus the wifi accesspoint of my LAN.

For several reasdions I reinstalled Raspbian but since then I cannot see my SSID anymore.
Other SSID's are visible, so the wlan works so far, however my SSID is not visible.

Another wifi device placed right next to pi 3 receives my WLAN w/o issues, so a dead spot is not the problem.

I placed Pi3 a few feet next to the access point, but without success, my SSID is not visible.
Changing 'Region' (TP-Link Archer C20i dual band) from 'Austria' to 'United States', my SSID is visible with Link Quality=61/70 Signal level=-49 dBm.
However, the 5Ghz band is not visible.

US Region allows up to 1W, most EU countries up to 100mW.

Is it possible that the pi3 wlan chip (BCM43143) is defect?


Thanks fore reading and hints.

AFAIK 5GHz is not supported by Pi3B internal wifi

BTW: have you set the correct wifi country code with

Code: Select all

sudo raspi-config
, section Internationalisation Options?

Changing to 'AT' did not solve the issue :cry: .

Connect a wired LAN, run sudo apt-get update && sudo apt-get upgrade && sudo reboot there's a newer WiFi driver in the raspberrypi-bootloader package that you'll get by doing that.

I updated as you suggested, but no success.
Still works only with US setting.

The strange thing is that I can see other SSIDs but not my access point.
Another wlan device, placed right next to raspi, receives a good signal (4 bars) from my ap.

Perhaps i have to replace this RasPi3.

Thanks for your time.

Reading Zosima's post Thu Mar 10, 2016 3:07 pm 'Raspberry Pi 3 can not detect my wifi'
I changed the channel from auto to 9 and the wlan is visible.
And yes, ch 11+12 are nor working.

So I think this this is a sw issue and wait for a new driver :)

Thanks for your time,
Wolf

Have you used sudo raspi-config to set your WiFi country code?

I updated the firmware with

Code: Select all

sudo rpi-update 41f8b4812ad653abf321b8c54cb4bee57ebdb129
as explained by blacai in
viewtopic.php?f=91&t=139550&sid=dc0271

This solves the issue for me.

Thank you very much for your time.

Why would you use an external wifi dongle if you have a built-in one?

I got my pi3 working with rasbian with those instructions channels 12 & 13 , thank you!

But I like to use archlinux and would like to get channels 12 & 13 to work.

Archlinux sees only channels 1-11.
