iwd provides only Legacy Access point (802.11b)

Hi,

I have my device started as AP and when I connect to iPhone, this warning comes (Legacy access Point 802.11b provides sub-optimal performance!!).
Is that possible to run iwd with 802.11g/n mode? my hardware support support all these modes.


Best regards,

The code has no support for this yet because in many use cases the AP
will not be the bottleneck, but we need to add it. Once added it would
be enabled automatically.

how big effort is needed to add the 802.11g/n support for AP. I can start to do that if you provide me with some hints. I will start to add 5GHz support for AP. Currently iwd support only 2.4 GHz. do you see any bottleneck in iwd? I am still using iwd 1.13.
which modes are supported in case the iwd runs in client mode?

So the work is actually done by the driver but src/ap.c will need to
announce/negotiate the support with the clients.  I haven't
investigated what changes are needed exactly, you'll at least need to
update the capabilities fields in some IEs in our beacons, add the
Extended Supported Rates, HT Operation & HT Capability IEs.  Some of
the information in those IEs will be based on what wiphy.c already
knows and some may need to be queried through netlink commands.

Best regards
