This seems to be the 3rd incidence where a new N800 will authenticate to a WLAN but is unable to route through to the internet.

lil_killer129 - you might want to read this thread and also this thread, then respond here with the details from Tools>Connection Manager>Intermet Connection>IP Address when you have established a connection to the NYPL wireless network.

If the addresses appear correct (we can advise if you aren't able to tell yourself) then it may be necessary to exchange your N800 unit (would this suggest there are units in the channel with defective WLAN modules?) Replacing the N800 worked for Rab, not sure if stellie resolved his/her issue - stellie, update please?
