Re: Info About Unsecured Access Point

Seni Seven <OneWhoLovesYou@xxxxxxxxxxxxxxx> hath wroth:

The report is a 25-30% signal with a 75-85% link quality, with the software
used by the Airlink 101 device.

The signal seems on the weak side, but the link quality is quite good.
I forgot to ask at what wireless speed are you connecting? That's a
good indication of signal quality. A low signal level or interference
will cause the speed to drop. My guess(tm) is that anything over
9Mbit/sec is acceptable.

What do you think?

Well, it's difficult to tell from just 4 pings. However, it looks
quite good so far. Try running ping for a minute or two continuously:
ping -t 192.168.2.1
<ctrl>C to stop. Try to get a feel for how consistent the signal
remains. Also try it when the connection switches over to the Comcast
web site.

(...) Anyone
who reads the page must turn off firewalls, virus protection, and popup
blocking software and download the software. I tried downloading it---the
link is <URL:http://cdn/downloadable_install_wizard.exe> which is clearly
not valid outside this intranet

Yep. That's an internal URL setup by the cable modem/router. It gets
expanded to something like:
cdn.sanjose.ca.sanfran.comcast.net

Like I mumbled... Comcast thinks the modem is not registered or the
cutomer hasn't paid the bill.

---but could not get the target object---no
download. Again, you see the download-this-install-exe page, but the
string of the URL is actually the string of the page you entered into the
URL address entry box, the content you wanted.

Ok, got it. My 2nd guess(tm) is that when you get that URL, it means
that the modem has either deregistered from the CMTS or some kind of
connection or authentication problem. Probably connection because the
http://cdn/ did NOT get expanded by the Comcast DNS server into the
full URL, which is why clicking on download, doesn't do anything.

Without the ability to triangulate the transmission signal of the access
point, we don't even know which direction the residents of the house live
in. However we know the first names of the girls who operate the access
point: they used them to make their SSID. We only need to knock on the
doors of several dozen homes.

Well, you could at least make the attempt. Grab a laptop and
directional antenna or reflector and take some bearings from different
locations. Where they cross is the likely location. If it's a big
apartment building, you already have the names which should help.

This Instaconnect service charges as low as $28 a month for a 12-month
contract, $40 month-to-month. But as I check now the detectable networks,
it does not register as I sit on the 1st floor of the townhouse. I
probably might see it in the upstairs room, but then who will pay for an
intermittent network signal?

Well, I don't think you're expected to be able to roam around the
house with such a distant and weak signal. However, a big dish
antenna and a local wireless ethernet bridge, should produce a much
better signal. If you can pick up anything with an inside laptop, you
should be able to do much better with an outside antenna.

I see no offer of a trial here. Perhaps that in itself is a sign.

Call or write them. The usual line is that you want to try their
service but you're not sure you can maintain a connection. You won't
get a 30 day free trial. More like a few days to test if you need a
better antenna or antenna location.
