Chase that later. You can do certain lower level tests easily, since you say you can get to some things and not others. You can test getting (directly) to a web site like this: telnet www.google.com 80 Telnet should recite an IP address for the web site. That tells you that DNS is working. And then it should connect. That tells you that to can get to it. Get out of telnet by typing ^] (ctrl-]) and the "q" and "enter". An example on the local LAN where I am: $ telnet web 80 Trying 10.11.0.9... Connected to web.blah.blah.blah.com.au (10.11.0.9). Escape character is '^]'. "web" has been looked up, getting 10.11.0.9. And telnet connected ok. GMail is https as I recall: telnet gmail.com 443 Same deal as for http (port 80). The results of these tests will help pinpoint your problem.
