I agree WiFI Analyzer is a great tool but a great app to go along side it for network information is "Overlook Fing"

My favorite Android apps are
[ul]
[li]Wifi Analyzer[/li]
[li]ConnectBot[/li]
[li]Astro[/li]
[li]Twitter[/li]
[li]Terminal Emulator[/li]
[/ul]
and from Google featured:
[ul]
[li]Androidify[/li]
[li]Google Sky Map[/li]
[li]Gesture Search[/li]
[/ul]

I was also able to get opkg there (have a CyanogenMod based rom) and install midnight commander, htop, rsync and dropbear... vi was already installed iirc. Using them via terminal emulator really sucks (no hw keyboard), but since dropbear is a ssh server I can connect to my phone from my computer.

Also tried Overlook Fing when I saw the post here and it looks very interesting :woohoo:
