My novice eye understands it is supported because AP appears in both "supported TX and RX frame types".

I also found this document about my wireless card : Intel Centrino Ultimate-N 6300 which says under Technical specifications - General - Roaming : "Supports seamless roaming between respective access points (802.11b, 802.11g, 802.11a/b/g, and 802.11a/b/g/n)"

GarryRicketson, you're right I don't want to install Windows over Debian. As for asking a tech shop I would prefer to avoid it, or maybe consider it as a last resort.

I think I have found something more. I tried to use NM in command line mode to setup the wifi hotspot but didn't succeed, I don't understand everything in the man page.
After, I tried different things and this is what I found :
I first turned on the wifi hotspot via the wifi settings window. Then :

Code: Select all

simon@sj:~$ nmcli connection

Wired connection 1 is my current ethernet connection.
WAX, eduroam and Lindihopp are wifi networks I have connected to recently.
And this Hotspot appears twice I don't know why.
Then I looked at :

ipv6.ip6-privacy:                       -1 (unknown)

Both Hotspot appears to be the same except for the uuid.
What bothers me is the line :

Code: Select all

802-11-wireless.hidden:                 yes
After some searching I ended up scrolling down the nm-settings man page.
In "Table 29. 802-11-wireless setting", entry "hidden", it is said that the default value should be FALSE, and also "If TRUE, indicates this network is a non-broadcasting network that hides its SSID. In this case various workarounds may take place, such as probe-scanning the SSID for more reliable network discovery. However, these workarounds expose inherent insecurities with hidden SSID networks, and thus hidden SSID networks should be used with caution."

I don't know how to switch the value of the "802-11-wireless.hidden" field. Should I even do it ?

It looks that way to me too.

Presumably because it is two bands ,

I am not an expert on this topic but I remember from when people in forums started mentioning hotspots that adhoc type connections didn't connect to phones. Adhoc was more for computer to computer, like in a meeting. You certainly don't want WEP security in 2017 it just isn't secure any longer.

I did find this site that was updated in Jan 2016 describing how to accomplish a hotspot on both Debian and Ubuntu that has WPA2 security. Maybe have a look at it and see if it makes sense for your use case.
