Sorry for poor quality, I took a picture of my TV at that point because no wifi, so no ssh access... Usually I'm uploading my pictures to picload.org and insert image then. This works for me |

The forum attachment feature is definitely broken.

RE: Raspberry Pi 3 loosing wifi - busy status
Hmmm, never seen this on my RPi3. And I'm unloading/loading this module many times per day.
Did you checked your power supply or can you use another one? Are you using onboard bluetooth and if not, can you disable t? |

RE: Raspberry Pi 3 loosing wifi - busy status
I only have a 2 Amps power supply that came with the Rpi3 kit.
I am not using Bluetooth. How can I check if it's enabled or not, and how to disable it? Thanks again. |

RE: Raspberry Pi 3 loosing wifi - busy status
Hi sorry for the late response...
I did not have a chance to try disabling Bluetooth but when left idle, my PI3 wifi seems much more stable. However, I found that I can "crash" the wifi almost 50% of the time by openning the tvheadend web view http://ip:9981/extjs.html If the initial page load works, then I can continue to browse the tvh configuration for some time. Otherwise, the page does not load properly and this triggers a full non recoverable wifi down. I have to reboot. If you or someone else has a Pi3 with tvheadend, I'd appreciate input if they have issues with the tvheadend web interface. Thanks ! |

I'm not using it on my RPi3, but having working config on my i.MX6 system. Hmmm, IMO the broadcom wlan (hw and/or sw) is absolutely crappy. I wasn't able to get it work on my i.MX6 system (incredible slow) and now same issues and extremely unreliable on RPi3. |

Regarding disabling BlueTooth, my /boot/config.txt looks like this (before mods): Code: #initramfs initramfs.gz 0x1000000 I added a second line for Code: dtoverlay=pi3-disable-bt I assume it's ok to have multiple "dtoverlay=xxx" lines? Also, could you let me know if you see anything unusual in the config.txt? Thanks again! |

RE: Raspberry Pi 3 loosing wifi - busy status
Hello,
I just want to confirm that with bluetooth disabled, I can still crash the wifi by accessing the tvheadend web interface. If it can help, here is the last dmesg output after the crash: Code: [174174.396705] brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012 Thanks! |
