DHCP leases etc I think not, at least without swithing from dnsmasq to full dhcpd. Wireless peers and (per interface) data counters should be possible as is. Packet capture (to see DHCP requests [in case dhcpds logging is not enough]) Are you using encryption (if so try disabling that first) ? once you post the output I (or someone else) can explain what the lines mean. What OS and version ? Once you post the hotspot backend output and we know the IP your N900 gets you need to try with manual IP configuration. There should be a "cursor" icon next to the ctrl, tab etc (if not try swithinc to/from fullscreen), activate it and paint everything, now in the top menu there is option to copy. Remember to change your encryption password (if you're using encryption) before doing this, otherwise anyone reading this thread can see it.
