The problem is with the wi-fi connection to our 4G Sprint Mobile Hotspot. Sometimes it works fine, but most of the time I get a screen when attempting to access a web page that says: This Web Page is not Available. The server at <a href="http://www.xxxxxxxx.com">www.xxxxxxxx.com</a> <<a href="http://www.xxxxxxxx.com">http://www.xxxxxxxx.com</a>> can't be found because the DNS look-up failed. And it continues with suggestions which I have tried. A friend helped me do the conversion from Windows, and is pretty adept at finding his way around, but this has him stumped as well. The wireless connection shows to be fine, and the whole time I'm having this trouble, my wife is surfing without any problems on her computer that uses Windows. While far from being an expert, I do have some basic understanding. So if you can make suggestions in laymans terms, it would be greatly appreciated. </blockquote>Worse comes to worse, you can try this.... open a terminal cd /etc type: more resolv.conf It should contain what Network Mangler sees as your name server IP addresses. If it's empty, there you go! If you're feeling froggy then use an editor as root (sudo gedit resolv.conf) and just add your correct nameserver addresses. Here's mine: ric@iam:/opt$ more resolv.conf nameserver <a href="http://67.142.165.10">67.142.165.10</a> nameserver <a href="http://67.142.165.11">67.142.165.11</a> Just plugin your correct addresses supplied by your ISP. Sometimes you have to get it's attention ...with a shovel. Make a backup of your existing file first, just in case. sudo cp resolv.conf resolv.conf.old You can always copy it back. I loathe Network Manager (Mangler) :) Ric </pre></blockquote></div> -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.</body></html></body></html>
