Ubuntu Networking :: How To Choose Between Wifi Hotspots With The Same SSID
Jan 24, 2010
I access the internet through a hotspot with the SSID "OzoneBE.net Open Access". Unfortunately this hotspot is massively overused, and on top of that the signal is weak. There are other hotspots with the same SSID nearby. They have weaker signals, but it's possible they may not be so heavily used, or that I might be able to find a line of sight to one of them, so I would at least like to try connecting to them.
Unfortunately KNetworkManager doesn't give you any way of choosing between these different access points and it automatically selects the most powerful signal, as far as I can tell. RutilT can distinguish between them, but when you try to connect to the one you want, it seems that KNetworkManager intervenes and chooses the alternative with the strongest signal again. However if I kill KNetworkManager, RutilT just won't connect to anything. It fails without explanation.
How can I get proper control over my network management so that I can connect to the hotspot of my choosing, regardless of whether it shares an SSID with another?
I have three routers (linksys wrt54gl, ddwrt). I'm trying to use wds bridging, got two of them linked, but not the third. All three routers have the same SSID. I'm using Ubuntu 10.04 netbook remix.
My problem is I need to choose which of these my laptop connects to. Right now it connects to the one router which isn't playing nice with wds. I need it to connect to one of my other routers. I see the other signals using nm-tool, but they don't show in nm-applet. I created a connection in NetworkManager specifying the SSID + mac address of the correct router, but the tray applet doesn't show any options for connecting to manually configured networks, and I can't find any other useful app. I suppose I could rtfm for iwconfig et al, but Ubuntu ought to have an easier way.
How do I choose a wireless network to connect to? The Ubuntu 8.10 help tells me to open NetworkManager, but the only thing I can find is 'Network Configuration' in System>Preferences. If I try to run NetworkManager in usr/sbin as a root, nothing happens whatsoever. nm-tool lists several available Access Points for my WiFi antenna.
I'm trying to install Debian via the net install CD and it kept asking me for my WiFi SSID and password instead of using the Ethernet chip which uses the tg3 driver. I took out the WiFi chip and the installer kept asking me which driver to use. I kept selecting tg3 but it wouldn't accept it. The tg3 driver has been in the kernel tree since early 2007. So what's up?
I'm running Debian testing. I am running the iwlwifi driver and I have an Intel Centrino Wireless-N 1000 card. I have a fresh install of iwlwifi and network-manager. After sleep or after being shutdown, network manager cannot find my network's SSID. I have to wait ~5 minutes for it list my SSID. I dual boot this laptop with Windows 7, and on Windows, I connect to the internet instantly after boot. I did not have this issue before, the only thing I have changed was installing blueman and the necessary components. After I installed and uninstalled these bluetooth components, I have been getting these problems. Here are some outputs:

I am setting up a netbook with linux.I need to edit a file and must know my SSID. What is a SSID and what is it used for how do I find out what mine is?
I have an intel 3945ABG wireless card. I installed "firmware-iwlwifi" with apt-get but I cannot enter in my network's SSID and wep. On Gnome, I click system, preferences, and networking, and I get that nice network menu, but it doesn't do anything!
It detects my wireless and wired card. I click on wireless, enter in my ssid, click WEP (hexadecimal), enter in my code. I choose auto DHCP. Then in the terminal I type iwconfig. It shows "wlan0" but the SSID field is blank. The wired works but I can't get wireless.
I have just installed FC12 on my machine - and gone Windows free for the first time ever. Now I do use various flavours of Linux on a daily basis but not from an installation/sys admin point of view so my questions here may seem a little basic but pleas eindulge me if you will!
Now, my network connection works perfectly well under the following scenarios.
The only scenario that does not work is FC12, wireless with SSID broadcast disabled.
I can only assume that it is an issue with my USB modem (a linksys WUSB54GS) since the same set-up works fine from my laptop running Ubuntu with an internal wireless card.
Now, I know from reading the forums that it's pretty easy to get around a disabled SSID broadcast but this is an itch I just have to scratch....what the hell is causing this problem?
nm-tool ouput is as follows:
I have tried using wpa_supplicant but I am not sure which driver I am using here - is it ndiswrapper per chance?
(Driver: rndis_wlan)
How I can connect once again to my wireless router with SSID broadcast turned off.
I was extraction some file through command line then I encounter on notification from winrar. This file exist what u want to do replace never quite I don't want that winrar will prompt me to choose action. Everytime whenever this situation occur it will overwrite / skip that file Syntax I am using for unrar rar e -pmypassword filename
I'm not sure if this is a problem with Ubuntu or with my router(s).
When I first installed Ubuntu about 6 months ago, I was able to connect to my wireless network without any problems. Becaue it's a laptop, I turn it off when I'm not using it.
But, starting about a month ago, if I don't use my Ubuntu computer for a few days at a time, it won't "see" my broadcast SSID when I turn it on. The SSID for my network just doesn't show up on the list of SSIDs that it detects in the area (but it still detects other people's SSIDs).
If I connect Ubuntu to my wireless network every day, it will automatically connect to my network without a problem, but if I don't use my computer for a few days, then it stops being able to "see" my SSID.
In order to connect, I have to connect to my router from my hardwired Win 7 desktop PC via 192.168.1.1 and re-save the wireless settings without changing them (the router is set to broadcast my SSID). Then my Linux machine is able to see my SSID again and connect wirelessly.
The problem is obviously with the router, right? So I bought a new router, and have the exact same problem!So now I'm not sure any more if the problem is with Linux or with both routers.
My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.
I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

I have a pc which has 2 network cards, 1 wifi and 1 ethernet card.
I'm using wifi card to connect to wifi network (internet) and i'm planing to share this wifi/internet connection via ethernet to wireless router (siemens sx763) so i can have internet on my other devices, e.g. mobile phone, laptop.
I have wired connection Ethernet (eth0) and 3G connection GSM (ttyUSB0). Firefox uses eth0, but sometimes, I want Firefox to use ttyUSB0. How could I do that?
I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:
Code:
I notived the following problems in /var/log/kern.log
I have 2 connections, wlan and wired, and I'd want to have a few websites (in my browser) to connect through the wireless connection while other go through the wired rj45 connection. s it possible? (without unplugging the rj45 cable...)
the only error message I can find comes from "dmesg|tail"all it shows is "no IPv6 router"any body know what is going on here or where where to look for more clues the next time I get around public wifi Oh the windoze washers and apple polishers don't seem to have any problems at all
I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.
I have somehow made 2 internet connections on my fedora 10. one is system default, which doesn't work. so I usually login and select from the top panel to the other working one. how to choose it from a terminal? then I can do it from a remote terminal.
Installed 11.2 last night with KDE4. Using "Connect to other network" I could see all the private networks around, including my own.
Mine has an hidden SSID and WPA2-PSK security. Regardless of what I tried I couldn't connect. Both BSSID and password are correct (but there was no other choice than "WPA/WPA2 personal" under security).
So I go to work today and connect to an unsecure network with a visible SSID (and a lower signal quality) without any problems.
Summary of issue: You cannot connect to a wireless network with a hidden ssid, while using knetworkmanager.This leaves you with the choice of using ifup, yast which uses ifup but provides a gui for new users, etc. But thanks to glistwan helpful post there is a simple way to fix this issue, while continuing to use knetworkmanager.Step 1 Get the wireless name of the hidden network, for example we will be looking for "Tree".Tree is not on the list of courseStep 2 Open the Terminal and enter super user mode.
I've been searching and trying to correct this problem for nigh on 12 hours. I would like to note that I know that hidden SSID are not necessarily much more secure. I have no permission to change the settings where I am. I'm running Debian Jessie. I have no way to get the server a connection other than the WiFi dongle I'm using. I have installed the correct WPA_Supplicant and Wireless Tools for my architecture/distro/version. I also have solved a sub-problem I had earlier; that the drivers for my WiFi dongle come with the kernel, but the firmware does not. That was remedied.
I can see my SSID in my iwlist scan. (iwlist scan | grep ESSID). My current /etc/network/interfaces looks like this:
Code: Select allauto wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf My current /etc/wpa_supplicant/wpa_supplicant.conf looks like this: Code: Select allnetwork={ ssid="hundley_1" psk=HashedPSK scan_ssid=1 }
The original .conf was created by using wpa_passphrase "hundley_1" PASSWORD >
/etc/wpa_supplicant/wpa_supplicant.conf I know for a fact that the security key is correct. I edited the .conf produced to what it is now.
Usign ifup wlan0 and ifdown wlan0 to start and restart the connection yields an error. The gist of the error is:
I have a supported BCM4318 "EDUP" wireless card. I am very, very new to opensuse, 2 days old to be exact. However I can read, so I followed the instructions listed in the "Getting Your Wireless to Work" with no avail. It is really weird. I am using the network manager. When I right click on the tiny blue wireless bar down below I see both my network and my neighbors. I click on mine and it asks for my WEP key, I enter it and when I mouse over the icon it sayS that it is obtaining network address. If I click on it at this point it says activating. Then it says waiting for authorization. I have used the fwcutter to download the latest firmware. I have even used ndiswrapper to install from the Edup driver cd. No good! The other thing is, that I am running Ubuntu 9 on the same machine on the same network with the same card and it works.
