WiFi issues - lost connections #131

Closed kilroykissenger closed 8 years ago

kilroykissenger commented 8 years ago

Wifi drops connectivity. Wifi symbol says connected but cant ping out. Happens regularly (at least once an hour) sometimes as often as every 5 mins. It has occurred across multiple networks and both 2.4 and 5 ghz.

I know this is short on logs let me know what I can pull to help and i will pull it.

running pixel 2 with 4.4.5ph+ with upstart

ehegnes commented 8 years ago

Does this issue persist with the vanilla mainline kernel?

kilroykissenger commented 8 years ago

Will test that out tonight

kilroykissenger commented 8 years ago

testing with mainline 4.4.5. Seems to be doing the same thing but will have to test it on other networks (current network could just be garbage)

stefanwiegmann commented 8 years ago

could that be the same as #121? I still have that issue on 5ghz. tried to turn off powersave, but it's still happening. It only happened on the samus-kernel, not on mainline

kilroykissenger commented 8 years ago

It could be the same but I experience the issue on both 5ghz and 2.4. I can usually resolve the issue by reconnecting but sometimes i have to disable and enable wifi all together

The only thing I can think of from this project that may have affected your interwebs is one of my first commits (f12b275) that updates the Intel® Wireless firmware. Is that firmware file up to date in /lib/firmware/? Alternatively, you could try some of the older firmwares listed at the iwlwifi site.

There was a downgrade from 4.4-7 (kernel version 4.4.5) to 4.4.-6 (kernel 4.4.2) since there was some sleep/wake issues. I've since downgraded to the 4.4.2 based kernel to sort it out.

I'm not sure if the same kernel (4.4.5) has WiFi issues, but I'd check to see if a downgrade to 4.4.2 will help.

I'm not having any WiFi issues myself. My only gripe is needing to restart my Network Manager service after booting up to connect to WiFi, but that's probably more to do with changed behavior in the Network Manager 1.2 update.

closing this as there's nothing in this repo that would affect wifi.

chepurko commented 8 years ago

Even though this may not be affected by this repo, does anyone with this issue have any updates on it? I have the same thing happen during long periods of use, say after every 45 minutes to 1 hour. The connection hangs while Network Manager looks like it's fine. But when I do a systemctl restart network-manager.service it hangs for 10 or so seconds and restarts the service, after which the connection returns. But the hangs can happen after this as well.

This has been with all kernels that I've used, and I haven't found anything online specifically about this Pixel 2 WiFi issue...

chepurko commented 8 years ago

And I've tried canning network-manager as well and switching to wicd. But as much as I wanted the problem to be with the dreaded Gnome Network Manager I had the same connection hangs in wicd, which leads to me believe it's kernel/hardware. But in either of those cases I guess there's bugger all I can do about it :stuck_out_tongue_closed_eyes:

I've never experienced anything like that. I use wpa_supplicant and dhpcpd without a manager, and it works well for me. If it really isn't a userspace issue, my suggestion would be to take a look at the iwlwifi debugging page, grab some logs and traces that show evidence of your issue, and post on the kernel bugzilla as mentioned in that link.
