I'm using a Nokia N810 running OS 2008 (version 5.2008.43-7; should be the latest). It can see networks up and down the street in my neighborhood and can connect to mine using WEP. I can also connect to free networks at restaurants and the like.
When I bring it into work, it can't see a wireless network ("No connections available"). When I use netstumbler on my laptop I can see a list of several essids showing green connectivity for the network. I know that the network has its essid broadcast, and I know that it's unsecured.
When I run iwlist wlan0 scan, I see several APs with no essid, but I don't see anything with an essid set. I have verified using iwlist that my hardware supports the correct channels and speeds.
I know this isn't a Nokia/mobile forum, but it's running what's basically a Debian kernel. Any suggestions on what to do in this case? I'm really frustrated by this.
