Regular expression help

Hi.
I have problem with regexp.
For example, there is list of wireless clients in access-list and I want view record, where comment contain some IP:

8 ;;; 123456 Some comment 192.168.2.5
mac-address=00:00:00:00:00:00 interface=sector signal-range=-120..120 authentication=yes forwarding=no ap-tx-limit=0 client-tx-limit=0
private-algo=none private-key="" private-pre-shared-key=""
... etc.

I type

/interface wireless access-list print where comment~".*192\\.168\\.2\\.5"

and receive nothing (Flags: X - disabled).
Where problem is?
Thx.

works for me on latest version.

Work. Thank you!
I forgot about version (3.22).
