[Bug]: Network module does not update ramp-signal when disconnected

[CameronAsselin]

Checklist

• I have read the appropriate section in the contributing guidelines
• I believe this issue is a problem with polybar itself and not a misconfiguration on my part
• I have searched for other open and closed issues that may have already reported this problem
• I have checked the known issues page for this problem.
• I have followed the debugging guide to narrow down the problem to a minimal config.

Steps to reproduce

1. format-disconnected = <ramp-signal> <label-disconnected>
2. Turn off wifi so you're offline.
3. <ramp-signal> does not update to ramp-signal-0, instead staying as the last <ramp-signal> icon it had before going offline. It WILL update to the proper icon when the wifi is switched back on however.
4. Re-launching polybar from the terminal WILL display the proper <ramp-signal> icon (ramp-signal-0).

Minimal config

[bar/main]
font-0 = EPSON 太丸ゴシック体Ｂ:style=Regular;2
font-1 = Hack Nerd Font:style=Regular:size=17;2
modules-right = network

[module/network]
type = internal/network
interface = wlp2s0
interval = 1
format-connected = <ramp-signal> <label-connected>
format-disconnected = <ramp-signal> <label-disconnected>
label-connected = %downspeed% | %upspeed%
label-disconnected = offline

ramp-signal-0 = ﮙ
ramp-signal-1 = 
ramp-signal-2 = 
ramp-signal-3 = 
ramp-signal-4 = 
ramp-signal-5 = 

Expected behavior

When I use Fn + PrtScr my laptop disconnects the wifi. I should see the emoticon representative of my connection switch to one with x's for eyes, indicating there is no connection.

Actual behavior

The icon stays as whatever my last signal strength was before going offline.

Opening the terminal and launching a 2nd polybar on top of the first shows the proper signal icon. In either case, hitting Fn + PrtScr again to go back online WILL update the icon to reflect my online signal strength. It's only switching to offline that I get this issue.

Hmm, from a quick look at the code, it seems like the code updating the signal values may not run at all, leaving the signal value at the old value.

Just as a sanity check, what polybar command are you using? Are you by chance using the -q flag? Or maybe have set the log level to errors only (with -l error)? This would cause a potentially crucial warning message to be swallowed.

Also, can you add the %signal% token to label-connectedand label-disconnected to see whether that value also doesn't update in offline mode.

[CameronAsselin]

I have only been running "polybar" with no flags on both startup, and when I run it from the terminal.

When I add %signal% to label-connected and label-disconnected it also doesn't update when switched offline, and also updates when switched back online. When re-launched from the terminal with the wifi already switched off it shows the correct icon and %signal% value.
