Just learned that you can join a network through a QR code. That's sick!

I thought you could only go to links / store plain text with QRs...

You can store any size limited information using that. So the only problem is interpretation of said information.

The 'rona vax certificates are also in QR codes.

Uses of qr:
- EPC QR (sending money)
- vcards
- geolocation
- sms
- bitcoin sending

wow 🌈🤯

Using the QR code doesn't work all of the time. I was in a client office today who offer guest WiFi with a QR code. My phone won't connect because it tries to use the previous password rather than asking for the new one.

@cmarshall10450 Just delete the connection from your phone, then reconnect.

@Fast-Nop yep. That's what I did and how I found what the problem was.

@Fast-Nop that didn't help connecting to the network from my phone, which was the main aim. I ended up connecting to the guest WiFi on my phone and then using that as a hotspot for my laptop

@cmarshall10450 Uh, what? Connecting from your phone was your aim, and using the phone as hotspot means you must have succeeded?!

@Fast-Nop sorry no, connecting to the guest WiFi network was the only objective as it was the only option, otherwise I would have had to go home. My laptop wouldn't let me provide a username or password and the 4G hotspot didn't give me enough connection to do anything. Working out why my phone wasn't connecting usually wouldn't have been an issue but it helped in this case with connecting my laptop to my phone that was connected to the guest WiFi.

@cmarshall10450 what the heck of crap is your os? Enterprise auth is complicated, but every current os can handle it.

@stop surprise, surprise its Windows 10. My laptop is very locked down by my company so it may be that but the client also has a very locked down network so I'm not sure what the issue is. All I know is that my phone works but my laptop doesn't. My role within the client has become more permanent now and this is the only time I've had an issue so its not great timing.

@cmarshall10450 there are a few things that come to my mind:
1. Tls. The tls configuration of the phone and windows could differ
2. Limited logins. The system could deny multiple logins from different devices
3. Buggy implementation

@stop In order to establish a TLS connection, you need to have an IP connection first - which means that you already must be in the wifi. Also, if you use the phone as hotspot, the TLS will still be done from the Windows PC, or else you'd get a TLS error on the PC.

@stop whatever the issue is, the client is paying the same for my time whether I'm working at home or working in their office. Its not a good look for me if it takes an hour and a half to connect to Internet each time I go in when it's fine for everyone else.

Forgetting the network on my phone works and let's me put in a new password. My laptop doesn't let me get that far even if I tell it to forget the network. It'll happily ask from a username and password to another one of their networks though.

@cmarshall10450 In my company, a number of WFH laptops were fucked up with wifi due to some additional "security" crap on top of Windows, some Cisco app. Couldn't be fixed from remote, so they drove in.

Didn't hit me because I have an additional LAN cable on my desk for the WFH laptop anyway. That goes right into the "guest" LAN port of my router because I don't want any of their shit to pollute my internal LAN.

@Fast-Nop enterprise auth with wifi usually uses custom ca-certificates to add an layer for protection of the credentials or as an means itself for authentication. An tcp/ip connection is not required.

@Fast-Nop might be some security clash with my company laptop and our client's network. Probably something to do with Windows or Sophos but this was the only time it was an issue and just with a specific network so who knows what the issue was. All I know is that, technically, the client paid £100+ for the time it took for me to be able to do anything. For that rate I'd want to be able to show them that it's not my fault but I'm not sure. I was thinking I could just go home and get connected but they would have wasted more time.

@cmarshall10450 Understandable. I basically stopped caring at all. I just file a ticket and book the lost hours as "IT issue".
