You may use the arp-table, or DHCP-leases. Not a perfect solution, maybe it's enough?

List arp-table

arp

List DHCP-leases

cat /tmp/dhcp.leases

... and combined

for ip in $(arp | grep -v IP | awk '{print $1}'); do 
    grep $ip /tmp/dhcp.leases; 
done

You have recent leases too, like a powered off laptop and a phone currently on another wifi network. –  Dereckson Aug 4 at 17:54

How about nmap?

opkg install nmap

Then do a stealth scan of your subnet (likely 192.168.1.0/24)

nmap -sS 192.168.1.0/24

This will list services running on the clients as well. It may also set off alarms if the client has port-scan detecting software (i.e snort) installed so be careful.
