Hello,
This is really annoying and has only happened to me with Bodhi so far:
The WiFi freezes and I can‘t exactly tell what triggers it.
Machine is a Compaq Presario V6000
The wifi module suddenly doesn’t work anymore.
Previously it was running in a Mint system and all was finde- until the change of OS.
The only solution to restart is to do a full reboot. No logout/login or restart of services works.
It turns Bodhi currently into an unworkable system even though it does work during long stretches, even days without issues and then suddenly it stops.
Am I the only one who has experienced this?

What WiFi chipset do you have?
You say it works on other distros? Might be a driver thing but other than that if it works on Ubuntu/mint it should work on Bodhi.

Hi, until now I assumed this to be a hardware issue on my Thinkpad X60s. It shows the same symptoms: wifi works flawless sometimes for days and then suddenly, usually when doing something like downloading bigger files or watching youtube, it disconnects and is disabled until I reboot. I have only ever used Bodhi on it since I got it, so I thought it is something like overheating or a similar hardware problem. But since this thread describes exactly the same problem and this one: bodhilinux.boards.net/thread/570/network-connection-fails-after-downloadsseems to be related, this might actually be a problem on the operating system side of things. Sadly it is not so easy to debug, because of its not a very reliably reproducible error. I will try do disable power management for the wifi, as suggested in the other thread.
My wifi is: Intel Corporation PRO/Wireless 3945ABG

Unfortunately my systems with Bodhi are currently using Ethernet, so I'm not able to help much. One of my systems, when using Wi-Fi did not experience any issues, however, that system was desktop. A few things to check possibly and I was curious -
Are you able to pull any system logs after the network crash?
Have you tried an IP release and renew?
Do you have any other devices on the network during the times of the network drop to confirm your network is not crashing?
Can you pull logs from your router?
I'm just spitballing but these may be a couple of items to check that may assist with troubleshooting assistance from our Team.
Please let us know and thank you!

Must be because I‘ve had (on this machine) Mandriva, Mint, Ubuntu- they all had no issues. Output as requested: 02:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)Also rfkill
ID TYPE DEVICE SOFT HARD
0 wlan hp-wifi unblocked unblocked
1 wlan phy0. unblocked unblocked |

I could get logs from the router but having had a look, it shows nothing. The network itself is ok, I‘m just using it from a different device to type this message. What I did notice is this: The LED of the wifi module usually flashes when connected indicating a live data link. I can turn it off manually, hardblock. But the LED stays in (should turn off). Its frozen in itself. Sadly that means: Close all windows and programmes and do a full restart. I cannot restart the wifi service itself (nothing happens). |

Thank you for the information gbano - at this point, it sounds like you have done a fair amount of digging around. Hopefully one of our more Linux back-end savvy team members has an idea. |

[…]
*-network DISABLED
description: Wireless interface.. and so on. Since this forum blocks TOR, I cannot copy & paste directly from my machine (which I defaulted there…), so this is a snippet. What jumps out is the contradiction between no hard/soft blocking but lshw showing it as disabled. This affects only the WiFi module. Once connected via LAN cable, it’s all fine. |

Do you have a WiFi switch on the laptop? I know that sounds patronising but I’ve missed such obvious things myself in the past.

If switched off with the switch, it shows Wifi as hardblocked on rfkill output, so eliminated this. I just had to perform another reboot. There was no big file download but the machine was left idling with no activity for about 30min. I had the same impression before that idle times on wifi use could trigger this. Don’t want to point into a wrong direction though. I keep trying how this can be reproduced. |

Just a short update here:
After disabling the power management for wifi, as mentioned above, the problem did not appear again for me so far.
So that might be solving it, but of course it is a little unsatisfying to not really understand the problem.
(still assuming to have the same problem as gbano, as the symptoms and the wifi hardware are the same)
I will enable Power Management again to try to gather more data.

Update from me: My WiFi keeps „crashing“ still, irregularly but it does. And every time it’s a full reboot and you have to put your work back together (or loose it), close the bonnet, put away your tools and start all over again. Bodhi slowly becomes unworkable with this! I looked into disabling the power management for the network. So I went to etc/NetworkManager/conf.d/default-wifi-powersave-on.conf as suggested here. The file is empty- and that’s where it stops because I cannot do the suggested adjustments, dead end! Is there any update from anyone else on this? I‘m seriously thinking of dropping Bodhi (which is otherwise really good:!). I can’t work with this bug. |

I checked my /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
[connection]
wifi.powersave = 3
Did you really have the proper file path? I can not see / char before etc in your post.

Stefan Sorry forgot the / character but I double-checked and the file is empty. However, I wonder if instead I should fill it with a string of „wifi.powersafe = (?)“. Maybe I should tell it explicitly *not* fall into powersafe mode. Will need to read about what options I can fill this file with. |
