Computer won't connect to internet

I'm having some problems with a residential computer that is running Ubuntu 9.10
It has worked fine for years. Client moved to a new home and has Comcast cable internet.
A couple of Comcast techs got him up and running after some head scratching.
It worked fine for a couple weeks but now he can't connect to the internet.

I've tried turning the power and and off on the modem.
I've checked the cable connection between the modem and the computer.
I'm connected through an ethernet cable.

The computer says that a successful network connection is established but no browsers will work.
I've tried Firefox and Opera. Also I get an error when I attempt to download updates.

Any ideas for where I should start troubleshooting this problem?

Linux Mint - The Trio

Linux Mint's claim to fame is usability and the search for the perfect Linux desktop. As a distribution Mint arrived on the scene in 2006 with release 1.0 code named "Ada". It never formally made it as a stable release, resulting in little fan fare. However with release 2.0 codenamed "Barbara" Linux Mint made its mark on the community. Over the next 2 years Mint released 5 versions and if you haven't guessed it already they were all codenamed after feminine first names.

Under the hood, Mint borrows heavily from Ubuntu, in fact over the years they've adjusted their release cycle to coincide with Ubuntu. However in 2010 they released a Debian centric release independent of Ubuntu. Unlike most Linux distributions (with a single software branch) Linux Mint has 3 separate releases.

Useful Ubuntu Linux Tips

My interest in linux first sprouted when I was a junior student. I used to play with RedHat 7 then, mostly CLI. After a few years of professional experience in different windows, I resumed my journey in linux during my master’s program in 2009, in fact, after my xp box got infected by virus. Since then, I have been using Ubuntu 8, 9 and 10 (Lucid Lynx, aka L linux). When I was using windows before, I would always like to have my own customized theme and settings which constantly drove me to follow even after using ... more on this link-


How to install MongoDB on ubuntu server

MongoDB wasn’t designed in a lab. We built MongoDB from our own experiences building large scale, high availability, robust systems. We didn’t start from scratch, we really tried to figure out what was broken, and tackle that. So the way I think about MongoDB is that if you take MySql, and change the data model from relational to document based, you get a lot of great features: embedded docs for speed, manageability, agile development with schema-less databases, easier horizontal scalability because joins aren’t as important. There are lots of things that work great in relational databases: indexes, dynamic queries and updates to name a few, and we haven’t changed much there. For example, the way you design your indexes in MongoDB should be exactly the way you do it in MySql or Oracle, you just have the option of indexing an embedded field.
