Not showing all networks

[igorkulman]

I run 2 home networks from my router, both using WP2-Personal, 20/40 MHz, 2.4 GHz, auto channel. With the "original" itlwm it connects to the networks just fine, I can see them in HeliPort.

With this fork I do not see my networks in the list and I cannot connect to them. I only see my neighbors networks, but not all of them, some than I see with HeliPort are also missing from the list.

[usr-sse2]

Is your network shown in log show --last boot --predicate 'sender="Black80211"'? If it's shown, which channel it's actually on?

[igorkulman]

Sometime I see it found on channel 11

[usr-sse2]

Please show more surrounding logs of both cases. The second one is not scan result but a scan request – macOS looks specifically for network with SSID "K" and any BSSID. (These logs are written to /var/log/wifi.log in case you already closed Terminal.

Here is the log log.txt

[usr-sse2]

I've understood the reason. As a workaround, set your channel to 1 until I release a fix.

[nemat-rakhmatov]

It does not work with 5GHz networks, does it? I can see neighbour's 2.4GHz networks, but no my own networks (2.4GHz and 5GHz)

[nemat-rakhmatov]

I've changed my 2.4GHz wireless channel to 1, and now it connects. My 5GHz channel is 48, it can not be scanned.

[usr-sse2]

fix-scan.zip Please try this. Scanning when not connected should be fixed except first scanning sequence during system startup.

[0xMisagi]

I had the same problem, my wireless network is on channel 11. Seems like your fix-scan fixed the issue for me.

[igorkulman]

Works for me also, I now see both my networks.

[ndhanh96]

yeah i was able to use this but don't have fancy feature like your images, still a win though, gps works.

Just hold Alt when clicking the icon.

holy moly , mac os is just as confusing as windows

@ndhanh96 Other menu bar items also have advanced menus with Option-click: for example, Sound, Bluetooth, Battery, Time Machine and WWAN.

Got a reboot after wake up from sleep

[usr-sse2]

Use keepsyms=1 to get a report with function names. However, as Black80211 is not in backtrace, it seems to be a bug in itlwm.

[igorkulman]

I know but your itlwm fork does not have issue enabled so reporting here. It is not a bug in the original itlwm as it works for me with sleep just fine.

[usr-sse2]

Does it happen always or only one time?

[igorkulman]

I switched back to original itlwm and heliport after the restart, but I can test again tomorrow.

I also get a reboot trying to unload your fork of itlwm, maybe it is related.

[usr-sse2]

macOS retains Black80211, so it can't be unloaded. If you unload itlwm, Black80211 will call functions of destroyed object, I should retain itlwm to prevent unloading.
