WNDAP660 Radius information are buggy in FW 3.7.9.0

Hi Raghu,

you can find the string "CONNECT 0Mbps 802.11b" in every radius accounting packet within the Connect-Info Attribute. It is an automatically generated value (implemented in accounting.c from hostapd) which uses the hardware mode (a, b, g) of the accesspoint and the supported supported_rates (Mbps ) of the access point. If nothing or wrong values are specified in the hostapd config file (like in our case) the defaults are used which leads to "0Mbps 802.11b".

I see two solutions if you want to fix that:

1 option)

The "hw_mode" is set to "ng" of "na" in /etc/ap.conf.wifi*

Acccording to the source code and the manual of config file this are not supported values which leads to (valid are a, b, g in version 0.5.7 of hostapd used in the firmware). Newer version like 2.6 can also use ad or any (see https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf for details). Maybe the Version 'sony_r5.7' is patched for that case, i didn't check that.

Set hw_mode=g in /etc/ap.conf.wifi0 and hw_mode=a in /etc/ap.conf.wifi1 should help and maybe the parameter "supported_rates" must be set as well (see https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf)

2 option)

Set the parameter "radius_ath_req_attr"  in the config file for the hostapd

"this overrides the automatically generated value". You could of cause use something more generall here.

Both solutions would be better than the actual one, because every client connection to the access point is presumably better than 0Mbps.

Please let me know if that helps or if you still need a packet capture?

Kind regards
