Hi, thank you.... it works.
Tried to change a User Profile of a Hotspot User logged in. There is a two profiles (default and advert). I tried to change profile using radclient
echo User-Name=999003,Framed-IP-Address=192.168.0.94,Acct-Session-Id=80f0004b,Mikrotik-Group:=advert | radclient 192.168.0.1:1700 coa secret
Received response ID 56, code 44, length = 46
NAS-Identifier = "ul_amigonet_office"
NAS-IP-Address = 192.168.0.1
but, no advertisement has been shown. The user profile was still default I think. I tried several syntaxes like Mikrotik-Group=advert or Group=Advert etc. but still no advertisement for logged user. Have you any experience with changing a hotspot User profile? (session time, rate limit etc. works fine, but Mikrotik-Group)
