Cable Modem -> Switch -> Hub -> My Computer
On our network is a local server where all of us share data on a common drive, including the database to web-based proprietary software.
While browsing the internet (for work, of course!), everything will be fine with reasonable speeds until it isn't. I'll get a message displaying in Firefox "Server Not Found". This message displays regardless of the site I'm using. The web-based proprietary software runs just fine when I can't browse the web. I also remain connected to the internet through Skype, LogMeIn, and Dropbox. The only thing I *can't* do is browse the web. This issue comes up with Firefox and Internet Explorer. The period of time where it works or where it doesn't is inconsistent. What's consistent though is that when I reboot my computer, everything works -- just not for long.
Any help / advice / thoughts would be appreciated.
