Ubuntu Networking :: Long Wifi Networks Last In The Available List?

Mar 10, 2010

I was on a car trip earlier, but we were stuck in traffic. The stop-go stop-go kind of BS. I pulled out my 9.10 laptop and figured I'd scan for wifi networks and see how good America was at securing their networks. (I work in IT support so it's one of those things I preach to no end yet people rarely listen).

I was using wifi radar, and picked up a truckload of networks every time we'd stop. But something didn't sit well with me. When I click on the network manager icon in the top gnome panel to see what networks were available, it never seemed to refresh.

Example - the first 5 networks I saw were 1, 2, 3, 4, 5. We would stop-go more and more and miles later when I'd see more networks in the area show up in wifi radar, yet hit my network manager, I'd STILL see networks 1, 2, 3, 4, 5 and not 30, 31, 32, 33, etc like I expected.

What kind of refresh time or cache or whatever does network manager have? I just didn't understand why I was seeing the original networks from 15 minutes/miles ago and it never seemed to update.

Ubuntu Networking :: Wifi Connects To Some Networks But Not Others?

May 7, 2010

I can normally connect to most wifi connections, but for some reason I can't connect to my broth's-gf-parent's network. Windows 7 can connect to it just fine, but not Ubuntu. Once in a while I'll go to a cafe, and this will happen there too.hough, like I said I can normally connect to all other wifi networks with no hassle

Ubuntu Networking :: No Wifi Networks Showing Up?

Feb 27, 2011

got a dell inspirion 15r (i think), and it comes w/ win7 (I HATE Win7) so i made him let me dual-boot with ubuntu maverick meerkat. (he wouldn't let me get rid of win7 cuz thats what his parents use.) It installed successfully, so we booted into it, and there was no wifi networks. I thought it was because wifi was disabled so i press the button i think its F5 but still nothing. I thought it might have been the comp but i booted into win7 (Que the Beethoven's fifth)... and it worked in win7 (thats a first) can someone help me. Oh and i forgot i used that terminal command to unblock wifi

DELL Inspiron 1501 Broadcom BCM4311 is the wifi adapter.The problem I am having is that I cannot get to search for wifi networks. It looks like the driver and everything is there but the wifi is disabled for some reason.I installed the drivers provided by the "Additional Drivers" application and they do not work.I also followed this fix and I could see in the menu that the wifi was added but I was not able to click it or look for wifi's URL...

Ubuntu Networking :: Refresh Available Wireless Networks List In Nm Applet?

Jul 4, 2011

Is there a way I can refresh the list of available wireless networks in the network manager applet? It works correctly when I've just booted but doesn't after I resume after suspending. There's just a message like "wireless networks not available".

I can assure you that the wi-fi is not disabled using a button (my laptop doesn't have such a button), "Fn" key combination or in any other way and the network doesn't go down when I need it.

Ubuntu Networking :: Can't Connect To Wifi Unless The Password Is Atleast 8 Characters Long?

Jan 20, 2011

When I need to type in the password to get on a wifi network, the "connect" button is grayed out and unclickable until I've typed in 8 characters for the password, making it impossible to connect to networks with shorter passwords. I'm not sure if this problem is unique to 10.10 or not, I've been using linux for a couple years now and I've never tried to connect to a network with such a short password before until last weekend, after my friend figured out how to change his password from the one his ISP set for him.

I'm running Xubuntu 10.10 on an IBM T42 laptop, here's the relevant hardware from the lspci command, 02:01.0 Ethernet controller: Intel Corporation 82540EP Gigabit Ethernet Controller (Mobile) (rev 03) 02:02.0 Network controller: Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04)

Ubuntu Networking :: Toshiba Satellite A215 Not Seeing Wifi Networks?

May 3, 2010

I'm using Ubuntu 10.04 - 64bit install with an A215. The wifi was working fine until today. Ubuntu seems to detect the hardware, and it shows the interface as being 'up', however no networks show up in either the network manager or 'sudo iwlist scan'. I'm not sure if it's a driver issue, or if the hardware itself died.Here is the output of lspci:

Ubuntu Networking :: Won't Connect To Open (unsecured) WiFi Networks?

Jul 9, 2010

I have no problem with my wireless network at home, or visiting friends, but it won't connect to public, open, unsecured WiFi networks, eg hotels, trains, ships.I'm using Ubuntu v9.10, NetworkManager applet v0.7.996, on a Dell Inspiron 1750 laptop.If I left click on the NetworkManager, the available wireless networks are displayed and I can see the relevent open networks, named as expected and shown without the lock icon. I click on the relevent entry, watch a spinner for 30 seconds or so and then it drops off and I have no connection. This happens for "all" open connections.If I look at my defined Wireless Network Connections now, I can see, eg, "Auto Internet@Sea, Last used: never". Editing that connection:

Ubuntu Networking :: WWAN Missing In Available Networks List To Connect - Vaio P

May 10, 2010

I've Vaio P39 with Karmic 9.10(2.6.31.21). Everything is ok excluding the WWAN. It just is missing in available networks list to connect (LAN and WiFi are ok).

Searching gives that WWAN adapter doesn't start at cold reboot and it's proposed to use Win7 to switching WWAN on and then restart. But it looks like - must have Win7 only to switching WWAN on...This kind of solution for some Vaio laptops

Code:

Probably bad searching from my side but I've no solution yet. Does it exist at all?

Fedora Networking :: WiFi Not Reliable And Can't Change Networks?

Jul 24, 2009

Fedora 10 (dual boot w/ XP) on Dell Optiplex with a Dell wirelessntennaI am on a university campus with campus-wide wifi network (so no router). I have a wireless HP printer that I want to be able to print to using an ad-hoc connection. The wireless antenna, networking, and wireless printing are all working in Windows XP (so hardware is OK). However, on the linux side, the wifi is really really finicky.

When I first boot up to fedora, it usually connects no problem to the campus-wide wifi network. If I try to switch to the ad-hoc printer network (which it sees), will not connect and, furthermore, it will no longer connect to the campus-wide network (and sometimes it doesn't "see" this network at all). It seems that restarting the Network Manager service sometimes helps to reconnect to the campus-wide network, but not always and I can't connect to the ad-hoc regardlessNOTE: I'm just barely a linux user, and I didn't set up my system - don't assume that I did anything that would be common sense and, if you can, walk me through your suggestions.

Ubuntu Networking :: 10.10 - In Network Manager Can View Wifi Networks Fine But Cannot Connect

Apr 28, 2011

I have been an Ubuntu user for a year or so. My level is still ultra n00b but I am trying. Whenever I update Ubuntu there is always a WiFi problem, always. So now I am having problems getting wifi to work in 10.10. In Network Manager I can view wifi networks fine but I cannot connect. I tried with wicd also but I got as far as "getting ip" and then it would hang up.

lspci

Code:

Code:

Code:

I am not sure what driver I am using as I don't know how to exactly ID my driver. I know there is a way to ID the driver using airodump-ng but I have yet to find it.
I have a feeling this is a driver issue as one time I was able to establish a connection that then dropped a few minutes later. I have a feeling I should be disabling/removing the current driver and replacing it with ipw3945 or possibly a driver ndiswrapped? The problem is I cannot figure out how to remove the current driver.

I was going to switch back to 9.04 but I thought I would try to manually figure this one out instead of taking the easy way.

Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue?

Fedora Networking :: Orinoco Silver PCMCIA Wifi Card Doesn't Find Any Networks In F11

Sep 21, 2009

I have Lucent Technologies Orinoco Silver 11 Mbps PCMCIA wifi card. It worked perfectly in Fedora 10, but after updating to Fedora 11 it stopped finding any wireless networks. The updating were done with automatic updating utility. The card works perfectly in Windows, I tested it today.

My laptop is HP nx6110 if that matters.

Here is the situation:

When I plug-out the card, the Network Manager disables wireless networking as it should. When I plug-in the card, wireless networking is enabled, so the system seems to recognize the card in some way.

If I try to connect to "Hidden wireless network" (because there isn't any wireless networks listed in the Network Manager) system tries to connect for a couple of minutes, and then asks wireless settings again. Orinoco card's lights DOESN'T blink normally when connecting to the network (one light should blink rapidly and one should light continuously, but both are blinking rarely or doesn't blink at all).

In System->Administration->Network in tab Hardware (hope those names are correct, I use Finnish version of Fedora...) is:

It seems that the card is detected right.

Here is what I have done to get the problem solved: In System->Administration->Network I have tried to connect to the wireless network manually (disabling the Network Manager). I can't get the connection. It gives me random error messages, sometimes "Check the cable" or something like that, sometimes just timeouts IP determination.

I have tried to connect different wireless networks, no connection. All tested networks worked with another computer.

No matter if I reboot or service network restart or plug-out plug-in the card... the problem still appears.

Tried to find (and reinstall) drivers:

Code:

No Matches found

Code:

Here is the output of lspci. The output is the same if the wifi card is connected or not.

Code:

LAN connection is working just fine.

Networking :: Manager Not Listing All Networks / Doesn't Show Them In The List When Left Click The Tray Icon?

Jul 3, 2010

I have two wifi routers. If I stand next to the main one with my laptop I can connect and access the internet no problem. The other router is in my office, and the bridging is messed up, so while I see the essid and bssid using 'iwlist scanning' and nm-tool, I can't connect to it.

Now, my main router's signal still reaches to my office, just not as strong as the borked router in my office. I need to be able to choose which wifi network to connect to without wasting time walking between rooms. I added entries for both in network-manager, but it doesn't show them in the list when I left click the tray icon! How the do I connect to the network I want?

Ubuntu Networking :: Using Tether Or Ad-hoc Networks Causes Headaches With Other Networks?

Apr 16, 2011

I am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.

What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.

I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.

Ubuntu :: Two Wifi Simultaneous Networks?

Jun 21, 2011

following a new motherboard install I've just done a clean install of 10.10. At first, I was using the default network manager wifi to connect to my router - I had the upturned radar beam type icon in the top panel showing me the strength of the signal and access, by right clicking on it, to things like Enable Networking, Enable Wireless, etc. I read that installing WICD via synaptic would install wicd and remove the default network manager, so this what I did. My wifi is OK but I still have my upturned radar type icon and a new WICD icon in the top panel. I was expecting the upturned radar icon to disappear - is this correct? If I right click on the radar icon I can click on the Edit Connections option and change things - it appears I have both the default network manager and WICD working at the same time.

Fedora Hardware :: BCM 4306 Can't See Any WiFi Networks / Resolve This?

Jan 13, 2010

I have FC 12 running and everything was working fine for about 2 weeks or so. Then today after I put my Daughter to bed, I booted up the laptop and it could not find any of the many WiFi networks that are present in my area, and when I tried to get it to connect to my home network through a saved configuration in the Network Connections Manager it kept asking for my WPA2 Password but it would not connect. So I got out my delopitated Cat-5 cable and tried to do an update and see if that would solve the problem. But alas it did not work (hence the posting of this tread ).

I even tried to unload the "B43" driver using code...

But that did not do the trick either. Is there any way to get it to work again without doing a re-install of the entire Operating System? I already had to do that, and it is a big pain in the A$$ because of a defective ATI Card in the laptop.
