General :: CLI Command Or Program That Will List Available Wireless Access Points?

Apr 3, 2010

Is there a CLI command or program that will list available wireless access points? I'm running Ubuntu 9.04 on a laptop and sometimes I boot straight into the CLI instead of a GUI. I know iwconfig can configure a connection but will not list available AP's.

Ubuntu Networking :: 10.10 Will Not Connect To Wireless N Access Points

Oct 7, 2010

I have wireless G and N access points in my house. The N network is set to allow only N connections. I have a Lenovo laptop with a Intel Wireless N chip in it, and after one of the 10.10 updates it stopped connecting to my N access point. The G access point works just fine.

The logs for the Wireless N access point alway show "Bas Password." I am having the same problem with either NetworkManager or wicd.

Ubuntu Networking :: Compaq 110 Cannot 'see' Any Wireless Access Points

Dec 11, 2010

Installed 10.10 maverick on my compaq mini 110, activated the restricted STA driver... But under the networking drop down it shows wireless as enabled but I cannot actually see any networks, there should be about a half a dozen to see. Works fine under windows. Before the restricted drivers are activated ifconfig shows eth0 and after eth0 and eth1 but when I do iwscan eth0 or eth1 it tells me this action is not supported! I have tried reinstalling from cli but no difference?

Ubuntu Networking :: Unable To Use Wireless With Certain Access Points

May 11, 2011

I am having trouble connecting to 1 particular wireless hotspot. It used to work in Ubuntu 10.10, but after upgrading to Ubuntu 11.04 it sees the Access Point, tries to connect but never succeeds. I can however still connect to my home router. Both use WPA2, both have a good signal. I have an ASUS UL30a laptop with a (output from lspci): Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) NIC I was thinking of installing the linux-modules-backport-net package?

Ubuntu :: Two Wireless Access Points - Pick Right Network?

Mar 1, 2010

I have two wireless access points in my home network. A Linksys upstairs and a Watchguard Firebox downstairs. The Firebox acts as the gateway for my network to the internet (well, the ISP's router anyway). I invariably use my Hardy Heron installed HP laptop downstairs, less than 10ft from the Firebox. The signal bar for the Firebox shows three bars, the linksys just one. So, why the heck does my Ubuntu insist on connecting to the Linksys everytime?! I can manually switch it afterward but still, it's annoying.

Ubuntu Networking :: Laptop's Wireless Card Can See Access Points But Can't Connect

Jan 15, 2011

I'm not exactly sure if this should be here and not in the Hardware & Laptops section, but seeing as my only problem is with WiFi, I'm guessing this is the right place. Under Ubuntu, my laptop (an Asus K42Ja, more details below) can see wireless networks normally. However, when I attempt to connect, it fails to establish a connection. Under Windows on the same laptop (dual boot), no problems are experienced.

According to this, there's a firmware bug in my wireless chip which causes connections to get dropped. I'm not getting connections at all, but I still tried the workarounds on that page with no luck. The router is a TP-Link TL-WR340G. My previous laptop, a really old one from 2003 running Ubuntu 9.10 was able to connect to that router without problems. The wireless card was Intel on that as well (but, of course, much older). The router is set up to use WPA for security. I didn't use WPA2 as I read something a while ago about problems with WPA2 and some Linux distros. Please correct me if I'm wrong here.

If anyone's curious, I'm posting this on Ubuntu, via an ethernet cable to the router mentioned earlier. Some tasty technical bits: dmesg (the latter half of the "timed out" messages is me retrying after double-checking the WPA key)

Ubuntu Networking :: Phy0 Has 100% Cpu Usage - Wireless Stops Detecting Access Points?

Aug 31, 2010

I used to use Ubuntu 10.04. Never had this problem. I went back to Windows 7 and then came back to Ubuntu, and 10.04.1 was released. After some usage of wireless internet, it disconnects from the access point, and phy0 has 100% usage. [URL].. I'm not the only one with the problem. I downgraded to 9.10, and haven't had that problem since the downgrade.

Ubuntu Networking :: Staying Connected To Wireless Network With Multiple Access Points

Oct 15, 2010

I can connect to my school's wireless network using the standard network manager, but often (not always) it repeatedly disconnects and reconnects every few minutes. Occasionally it also prompts me for the security information again (even after it previously connected successfully).

By running iwconfig when it's on the fritz, I can see that it's often switching access points for the network - which is what I think is causing the problem. It disconnects and reconnects even when the signal strength for the current AP is fine, and it will often switch to an AP with a weaker signal strength.

Programming :: Script To Flash All Access Points Does Not Work

Jan 8, 2010

I'm going to write a script that flashes all AccessPoints in our network, with an expect script. Unfortunately the following code doesn't work.

cat: invalid option -- o
Try `cat --help' for more information.
So it doesn't understand the pipe thing anymore. Is there a way to get this command working?

Networking :: Data Acquisition System For Vehicle - Access Points

Aug 21, 2010

A friend of mine is building a data acquisition system for a vehicle that will wander through city streets and roads and perhaps even off-road places. At the end of the day, back at the garage, the data must be downloaded and, if needed, upload an update of the data acquisition program. The network is wpa_supplicant, and it was chosen an USB device, because the original computer did not had any wireless interface and do not have any other possibility. The problem is that, when the vehicle comes back, very often there is no access to the on-board computer, or the connection lasts just a few minutes.

The computer must be reinitialized so the connection is back and the scripts run completely. Sometimes the connection is made, but the guys are so used to restart the computer that they do it anyhow, and then the connection does not come up, they have to restart it again.I have being thinking, as the vehicle drives all around, perhaps finding some access points along the day, if this connection trials - and failures - are messing up something. Or, the connection instability as the vehicle approaches the garage, could be driving his scripts mad?
