On which SolusOS is based ? Linux ? If so, please send here the standard output of following command:
nmcli --terse --fields active,ssid,bssid,mode,chan,freq,signal,security,wpa-flags,rsn-flags device wifi list
I suggest you to change a little the ssid and bssid for confidentiality reasons.
Yes, SolusOS is GNU/Linux based (I'm running kernel 5.2.7-123.current
to be exact).
This is the output using the command you provided:

For privacy reasons, I have only listed the networks here that I own.
After taking a look at the output myself, I noticed that the 5GHz
networks are seperate from the 2.4GHz
networks.
Could this be the cause?
Yes definitevely. Everytime a network use a different frequency, it has to be emitted by a different wifi router (or at least a different antenna on a router) and so it is identified with a different bssid. Most of the time router use same ssid so that it is transparent for the users and computers switch from one to another with transparency too. But it is not exactly the same network, you can have different security rules for each network for example.
If you use network repeaters you can also have the same situation : several routers (or antenna) and so several real networks even if only one is visible in the graphical user interface.
I cannot see the last caracters in the bssid of the different networks Roelofs but I think they are really different wifi networks. They may be binded in the router so devices can talk to each other on the unified virtual network but it doesn't seem to be the same physical network.
I have taken a look and yes, they do have different BSSID
(05
and 06
as final characters).
I have currently written my own code snippet to do some filtering to get around this.
I'll leave it here, feel free to integrate it (maybe with a configuration flag?) or leave it be (depending on how you feel like it). It's not perfect but it seems to do the job.
// Remove all duplicate networks from the array
var networks_temp = [];
networks = networks.filter((item) => {
// Check whether we already have this SSID in our results
// Add it to the networks_temp array if we don't
let i = networks_temp.findIndex(x => x.ssid == item.ssid);
if(i <= -1){
networks_temp.push(item);
return;
}
// Check whether the signal quality - with a small margin - is higher or not
// Skip this network if it's much weaker anyways
if((item.quality + 5) < networks_temp[i].quality) return;
// Check whether new network is using 5GHz or not
// Skip this network if it's using 2.4GHz anyways
if((item.frequency) < 3000) return;
// The network is 5GHz *and* has a relatively higher signal, use it insead.
networks_temp.splice(i,1);
networks_temp.push(item);
return;
});

When I use
wifi.scan()
, I get double results of some networks (albeit with different network strengths)Expected Behavior
Only a single entry per network in range
Current Behavior
Multiple entries for a network in range
Affected features
Possible Solution
Checking the scan results for duplicates and either updating or removing them.
Steps to Reproduce (for bugs)
add following code to a nodejs project
Context
It's making my results list a little mess because it has plenty of duplicates (I can count my homenetwork in the list 4 times).
Your Environment
Qualcomm Atheros AR93xx
(unknown specific card)
