Fiber cut unexplained

It looks like the first outage ended with a temporary repair which was followed by perhaps a more durable fix. In between we had problems with the TWR edge router in Galax which made for a bruising week. 

New life for an old Nuvi

Submitted by tarvid on Sun, 10/02/2016 - 11:44
I bought a Garmin Nuvi 1450 at the recent Pender Flea Market. It is about 7 years old but Garmin graciously offered a firmware update. Garmin wants $90 for lifetime maps for this device so I searched and found newer maps in the 'net. The new map is larger than 2 GB and the 1450 has only 2GB so I searched at Staples for 4GB microsd card. The smallest was 16GB and 'net wisdom is that all Nuvi's will support 8GB. So I went to Microcenter and bought 8GB microsd cards for $6. I stuffed the microsd card into an adapter and plugged it into my Dell Studio, formatted as "FAT".

TWR router(s) DHCP

A wireless user called in a panic when his Internet connection went down. Dispatched Ray to the site and suggested bouncing the radio. That means disconnecting the cat5 cable from the POE to the radio, wait 5 seconds, plug it back in, wait two minutes or so. No luck. The POE is inside, the radio is outside. The easiest and least expensive fix to try is replacing the POE. Ray has one in the van and replaces the POE. Yay the Internet comes back up. Not so fast, a few minutes later the Internet is down again. Time to retrieve that POE from the trash.

Configuring a NanoStation as an AP

Submitted by tarvid on Sun, 09/25/2016 - 12:52

By default, a NanoStation wants to be a “station” or client. The screen shots below are after configuration. That’s good in that my NanoStation is working as an AP and bad in that it doesn’t show the fumbling I did to get there. Out of the box with your laptop connected to the primary port and your IP address set to, enter

Cheap Wireless bridge

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.

Grant is back up.

Submitted by tarvid on Thu, 09/22/2016 - 21:04

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.
