I have had ministumbler on for a while and have now removed it because as stated ealier in this thread the Axim searches for WiFi network with the Dell Wlan software, I used to use netstumbler on my PC laptop and it always found networks and showed all their info but with ministumber i just got the drop down alert that the Dell software pops up when it finds a WiFi network, ministumbler never EVER showed me any info about a network, so it's gone and I have a bit more memory. I am finding btw that the wifi antena is stronger than my aiport card in my 12" ibook, it pics up networks that are slightly out of reach of my MAC, just thought i'd mention it. The advantage (i thought) of having wifi on my PDA was that when i'm looking for a wifi hotspot my PDA can do it and I don't have to boot up my ibook or drive around with it on the passenger seat, but sometimes i get a network alert, connect to it to make sure it's accessable, so i get my ibook out and it can't find the network while my Axim is sat next to it surfing the net.
