Wifi won't reconnect after waking up from Sleep mode

I have a consistent issue on two different Pixel Book Go's (m3 & Intel i7) where after a while, the OS falls asleep from inactivity but when I wake it up. It takes forever to join Wifi no matter which Wifi Network I'm on. Rarely I have to restart ChromeOs for it to connect.

The only work around, is to go to Wifi Settings or Known Networks and force it to connect a few times.

Do you know model of wireless card these use? If you open a crosh terminal and run `dmesg` it should show in the output if you scroll back a ways.

I ask because there have been some funny bugs with Intel cards when associating with network SSIDs that are broadcasting both 2.4 and 5 GHz with the same name.

Try copying/typing this URL into the address bar and then use control f to search for `network-` and expand network devices and network_event_log which should show you some info.

chrome://system

Expanding the `lspci` entry should have an entry for Network and possibly one for Communication and will probably have a manufacturer next to that which doesn't help narrow down the model but gets you closer.

Sounds like you could be affected by this bug too.

https://bugs.chromium.org/p/chromium/issues/detail?id=943157

Do you happen to know if your wireless SSID is the same for both 2.4 GHz and 5 GHz? That seems to consistently cause problems with Intel cards. I ended up modifying my network settings on my router to avoid that and I haven't really had an issue since.
