Network Extender Observations

For an antenna I'm using a simple wire running from the radio to the outside through a window. This probably is a big factor in my observations. I'll be rechecking when I get the doublet (600 ohm feed) up in the air.

I just received a Linksys WUMC710 Wireless-AC Universal Media Connector. I updated to the latest firmware. The idea is to give me a little more flexibility and mobility. Setup using WPA was terribly easy. Connection to the radio took two tries but I configured a reserved IP for the radio and subsequent reboots seem OK so far. The network stats show excellent with no drops.

Noise. Tons of noise. Here's some results:


7.070 MHz, CW mode, 500 Hz filter.

On Wire Antenna:
On wireless extender located close to the radio: -85.8 dBm
On wireless extender about 6 feet away: -86.4 dBm
Direct Ethernet to computer, extender power on: -99.1 dBm
Direct Ethernet to computer, extender power off: -100.1 dBm

On Dummy Load:
On wireless extender located close to the radio: -106.8 dBm
On wireless extender about 6 feet away: -106.6 dBm
Direct Ethernet to computer, extender power on: -105.9 dBm
Direct Ethernet to computer, extender power off: -106.9 dBm

I haven't gone through any noise mitigation techniques yet. I believe (based on the dummy load examples) a proper antenna will eliminate most of the added noise. Location, use of ferrite chokes, rechecking station grounds should clear the issue.

I'm curious about your impressions of network extenders and, in particular, this model.
