wireless internet

[dan moylan-4]

i'm puzzled.  i'm running ubuntu 9.04 on an asus eee pc
1005ha which has a built-in wireless n device.

at home, i have a netgear mr814 wireless router, essid
moylan-net, and have no problem attaching to the internet.
  iwlist wlan0 scan
shows me all the access points in the neighborhood in
brookline.

my /etc/network/interfaces:


  auto lo
  iface lo inet loopback
  auto wlan0
  iface wlan0 inet dhcp
  wireless-essid moylan-net






/etc/init.d/networking restart always brings up wlan0.

currently i'm visitin my sister in issaquah, wa, in a
retirement community, with wireless access essid bwood.

my sister's computer shows good wireless signal strenghth.
on mine, iwlist shows no scan results, and of course i'm
unable to connect.

now, at my nephew's, a little ways away in sammamish, wa,
iwlist shows his access point and i'm connected to his
router -- no problem.

i haven't a clue as to what's going on.

any thoughts?  all suggestions welcome.

Your sister's ESSID is not being broadcast. Get it from her
computer, then apply it by hand.

In situations where you don't have access to such an assistant,
a wireless sniffer can help.

i did.  stuck it in /etc/network/interfaces, ran
/etc/init.d/networking restart, and failed to connect.

also tried the NetworkManager gui, and had no better
success.

http://www.kismetwireless.net/ is the usual one.

Links at http://tuxmobil.org/linux_wireless_sniffer.html may be
of use, too.

According to the amazon page for the 1005ha, this device has draft 2.4Ghz
n wireless.  N wireless can also support 5Ghz.

Any idea what frequency their wireless is running at?  While its a less
common choice, if its 802.11a or 802.11n running in the 5ghz frequency,
that could explain why you're not seeing it.
