The Tenda N301 is a cheap but functional 2.4 Ghz wifi router. It will not run OpenWRT nor DDWRT and is a single band router. I buy them at Microcenter sometimes on sale for less than $10.

A new fiber was installed at the Grant facility replacing the one that had been breached. The breach is not beleaved to have been perpetrated by Russian rats nor part of a wider conspiracy. However a cable was disconnected at our Fairfax Virginia Facility on Sunday. A temporary cable was installed and equipment moved to provide limited operations. No culprit has been identified. Almost back to normal.

All of Grant is down - maybe more

TWR has been notified. We are monitoring.

We (WideOpenNetworks) dispatched technicians last night when the outage started, they were not able to resolve the issues and are going back out today.


Technicians have identified a fiber break between the building and the tower. We are trying to make enough slack to splice the drop tonight but it appears that will be difficult because of the location of the break. A crew is being scheduled to install a new drop.

There are times when one needs to know the traffic on a network to track down compromised users. It turns out our edge router for the TWR network in Galax is capable of providing the information required. 

I set up a packet sniffing streaming receiver here in Fairfax but Mikrotik is adequate for the task so I don't need to collect the information remotely.

I don't put on a stole when listening to confessions but I, like Shultz, know "Nothing!" Be assured that Big Brother has collected enough information upstream to reveal the most sordid details of your affairs.

The office in Independence is closed. All operations are now in Fairfax, VA. That means a lot of duplicate equipment. I plan on tailgating at Winterfest in Annandale on Sunday.

I recently upgraded my workstation monitor with a built-in camera and microphone. The entertainment machine has an external camera and microphone (Logitech, Inc. QuickCam IM/Connect).  Both have Google Voice installed and "Hangouts" appears in my tools menu. I normally have Gmail open when I am around, so invitations to video chat should get my attention. Gmail is probably the primary means of contact but a video call may be more effective for complex issues especially when screen sharing will demonstrate a particular problem.

The ground rules:
