WiFi Access Denied: 2009-12-25
07:55 PM: I’m now posting from sister Christine’s computer, at her house. Currently working a puzzling networking problem. They have Verizon DSL here, Westell modem, with WiFi capability. In fact, I’m accessing the blog through the wireless connection, and from all the computers that normally connect through this network, connectivity is fine.
However, nephew Trey brought his computer tonight, hoping to connect to the Internet through sister Christine’s network. He is able to connect, but only with limited connectivity; he cannot access the Internet, even though he has successfully logged into the Westell access point. Diagnostics on Trey’s computer say that the network to which he’s logged into, does not have a valid IP configuration.
At this, I speculated that the firewall on the Westell was only allowing Internet access to authorized computers, and that Trey’s machine is not authorized. Thus, I logged into Christine’s router (http://192.168.1.1/) to inspect the firewall settings. I discovered that she’s got the firewall turned off (no security setting). So, a blocking firewall is probably not the problem. Christine did say that her son, Garrett experienced similar difficulty, when he first connected his new laptop, and had to call Verizon to get the connection going. We may have to do likewise here; but not tonight.
