my configuration is as follows: Internet connection coming from the office (don't know details) => D-Link DIR-632 => Desktop Computer (Win 7), printer, Vonage.
I have Microsoft Lync and Outlook 2010. Both keep dropping on and off. For Lync it disconnects and then reconnects every 5 minutes or so. Outlook sends and receives fine at first and then eventually it stops receiving mail. I use it with an Exchange Server (Office 365), Hotmail (Outlook Connector), and IMAP (gmail). If I then restart Outlook mail starts coming in and eventually stops again.
The router is not restarting because I can still browse the web and Windows doesn't notify me of a failed network connection.
If I remove the router out of the equation (plugin in the internet directly to the desktop), this behavior doesn't occur.
My question is, is this a bad router or do I need to configure something?
