Wireless Interference-Meter Celebrates Solar Flares?

    Having experienced mysterious wireless problems recently, I made a nice interference meter. It was impressive when it was detecting streetcars and microwave ovens. But today it's been acting spectacularly. Could it be the Solar flares?

    Transmit rates of 1, up to 100% packet loss, minimum ping times of 13,000 ms. With the router just 8m away.

    200 1420-byte packets per second.

    Here is some data from the wl command:
    (A WRT54GL)
    Code:

    Here is another site, with an RT-N16:

    I would be interested in comparing notes with others about how to get useful information from the wl command, and also about what wl and wl0 mean in the NVRAM.

    (In other news, the 9dBi antennae have arrived, and I look forward to seeing if they are actually antennae. ;-) They were very pooly packaged, one is quite bent at the top, and all the sticky labels have come unstuck. "Likuda" brand, from cenyglobal. One of the stickers, in very tiny print on black background, suggests using channels 2,3,5,7,9. It also suggests using broadband speed tests to test the wireless antennae.)
