ad-hoc in 5GHz

ad-hoc in 5GHz

[Belisko Marek]

Hi,

this should be general question. I'm using [0] ralink driver to setup
ad-hoc mode. It works fine in 2.4GHz band (channel 1) but when I try
to setup ad-hoc for 5GHz (channel 50) it seems it's not working at all
(I tried to scan with other device but I cannot ad-hoc network). So my
question should ad-hoc mode work in 5GHz band also or there are some
restrictions? Many thanks.

It's Realtek not Ralink, right ?

Depending on regulatory setting IBSS or IR (initialize radiation) can be
prohibited on some 5GHz channels, check "iw phy" to see which 5GHz channels
are allowed to use. If HW hardcoded regulatory do not prohibits IBSS on all
5GHZ channels it can be matter or setting proper regulatory domain
(configure timezone properly and then setregdomain will set domain based
on it).

Ah sorry yes it's Realtek.

I did check that and I use 'iw reg set US' (to setup other regulatory
than 00). But despite of that
I still cannot get 5GHz working. Maybe it's driver issue. Thanks.
