At the coffee shop where I work we have a Netgear GRH614v4 802.11g wireless router for our customers to connect through. Just today (and never before) I cannot use my PowerBook to connect to the internet through it! It detects the network just fine, but no data will transmit over the wireless. It's not the modem, as our hard wired computers connect just swimmingly (I'm using one of them as we speak) and I doubt it's the router because it's still sending out a signal. No customers have come in, though, to use the WiFi, so I can't be certain. In the meantime, does anybody have any ideas of what to do? The router is loaded with the latest firmware available, the connections are, etc. Any help is much appreciated.
