Ubuntu Networking :: Wireless Connection Working, Network Appears In List, But Does Not Connect To It?

Mar 16, 2011

I'm having some problems with my wireless connection. I'm on Ubuntu 10.04, on a HP ProBook 4520s, with a RaLink RT3090 wireless network card. I installed the drivers (hopefully correctly), the wireless seems to work correctly, it scans and finds networks, but when I try to connect to one, it times out after some time, while still attempting to connect. I also have a wired connection that works correctly and without problems. Other computers that try to connect to said wireless network manage to do so without any problems, so this has left me a bit baffled, since, like I said, everything seems to be in order.

I'm a new Ubuntu user, so please tell me what other information I need to provide in order to easily and successfully facilitate troubleshooting this, because it is, as you can imagine, quite aggravating, having a laptop that needs to be connected to the internet through a cable.

OpenSUSE Network :: Keyring Password Window Appears When Connect To INTERNET Via DSL Connection

Jul 30, 2010

I'm a bit puzzled by new "keyring everywhere" feature, well the case: Now I'm using 11.3 brand new suse and just when I want to connect to INTERNET via my DSL connection, a keyring password window appears, well I fill in the keyring password and hit enter, then another window pops out with my DSL connection asking me to enter a password for my DSL connection (but I've already set it up it before) and ok, I enter my password hit enter, but DSL window pops out again! and nothing happens,

I do it several times like a puppet, then I delete my DSL connection and make it again, so everything works with passwords no(no keyring is being promted). SO what do I do wrong? How can I disable this keyring feature, I do not need it at all, why do I need to recreate my connection every single time?

Networking :: Wireless Network Connection - Router - Won't Connect Fast - Automatic

May 26, 2009

My computer takes a while to connect to my Linksys N router.

It used to connect in a snap of your finger automatically.

Now it does not.

Yes I have tried manual configuration, and double checking the password, ssid, protocols, and security type.

WPA2 personal is the security type.

There are maybe 4 different ways I know how to connect. The most annoying thing is when this box pops up saying to type in a password for the network connection.. and keeps popping up even when everything is right.

All I need is a reliable, easy, and automatic program to connect me to the internet, maybe even before I log into my system.

Linux Ubuntu 8.04 LTS Desktop Edition is my system. Brilliant system.

Ubuntu Networking :: Wireless Network Connection Not Working After 10.04 Intalled

Apr 29, 2010

I just finished upgrading from 9.10 to 10.04 via the Update Manager. My first noticeable problem is that my wireless connection with my home network no longer functions on my IBM Thinkpad T42 laptop.The Network Manager applet shows that it detects my home network (and those of several of my neighbors), but I have not been able to get it to connect to this network. I've been using WPA & WPA2 Personal settings for security, and the Network Manager applet had correctly picked up the password that I had been using under 9.10. I've searched the Ubuntu Forums for "wireless T42" and thought I'd found a solution in a posting that recommended using the "wcid" network manager, but I've been unable to find wcid either via the Synaptic Package Manager or the Ubuntu Software Center.

1. I've noticed that in Lucid Lynx the Network Manager applet's icon in the top panel is no longer the vertical bars symbol that it displayed in
Karmic Koala; instead, the icon is a radiating fan display. In the Network Manager's edit Network Connections window, this fan icon is shown on the Wireless Connection tab, while the vertical bars icon is shown on the Mobile Broadband tab.

2. The Wireless Connection tab shows, on the line in which it shows awareness of my home wireless network (as "Auto 389690") that this connection was "Last Used" "1 month ago". It should be saying something like "today".

FWIW, the Network Manager detected my wired "eth0" connection with no difficulty.Both Jaunty and Karmic picked up my home wireless connection without any problems. Now I have no idea what to try next.

Ubuntu :: Connect To A Wireless Network Not On The Indicator Applet List?

Ubuntu :: WPA/WP2 Wireless Connection - Unable To Connect To My Network

Oct 5, 2010

I have just installed Ubuntu 10.04 on my HP Pavilion dv5. My laptop has a Broadcom 4312 wireless adapter. The driver for the adapter was installed by Ubuntu as a proprietary driver. The wireless light is on and I can see the available networks, but I am unable to connect to my network. The correct authorization is set(WPA/WPA2) and I have entered the passphrase correctly.

I am able to connect to the wireless network successfully from my Windows login(that is how I confirmed that the passphrase is accurate). The network shows that it is trying to connect, but the wireless authentication dialog(asking for the passphrase) keeps popping up. Incidentally, the same thing happened when I tried openSuSe and Fedora on a spare laptop. The windows systems can connect, but not the Linux systems.

OpenSUSE Network :: Working Wireless Connection But No Internet / What To Do?

Jan 15, 2010

I've installed opensuse 11.2 on an old IBM thinkpad. The install went without a hitch and when I got to the desktop I inserted my Dlink DWL-G132 wireless USB adapter. Opensuse immediately recognised that a wireless device was attached and I could see my wireless network listed. I entered my WPA password and was able to connect to my routers configuration page by entering 192.168.0.1 in the URL bar of firefox. For some reason I am unable to navigate to any webpage. When I enter a URL firefox acts as though there is no internet connection. The only way I can get the internet on my laptop is to connect it to my router with a cable. I used a wired connection and ran the update utility thinking that perhaps an update would fix the issue but it did not. I know the adapter works because the laptop used to have windows xp installed and I could connect fine with that.

Does anyone here have any idea why I would be able to connect wirelessly to the routers configuration page but not to the internet? I appreciate any advice anyone may have.

I upgraded to 10.10 and have everything setup, installed my wifi card fine with ndiswrapper so I can connect to my neighbors which isn't protected but mine is. Everytime I try to connect it will ask for the WEP so I put it in, it tries connecting then ask for the WEP again then repeats over and over....does 10.10 not like WEP connections? I don't know what to do.

Ubuntu Networking :: Wifi - Set Up The Wireless Connection Using WPA But Could Not Connect

Mar 19, 2010

Using an old (5 year) laptop with XP loaded I installed wubi to save altering partitions etc. It all downloaded fine and connected to the internet by wire. I set up the wireless connection using WPA but could not connect. The wirelsss card does see my network and others. After lurking around the forum and trying various things I found that I could connect without encryption. The more I read the more I became confused.
Anyway what I could glean about my Wireless Card it is a Intersil Prism2 mini usb adapter - but also shows up as an Acer ?? Warplink 802.11.

Using lshw I found this reference to wireless

I became even more confused and got a bit lost using the various codes in the terminal and looking up things about drivers etc but would like to persist.

Ubuntu Networking :: Wireless Connection - Can't Connect To The Internet

Aug 29, 2010

i just installed the 10.0.4 version. My problem is that I cant connect to the internet. When I add a new wireless connection, it says that its connected but i cant ping the router or connect to any websites. It keeps auto assigning me with a 10.42.43.1 ip which doesn't make any since because my router's is nowhere close to that.

Ubuntu Networking :: Rebooted And On Restarting The Wireless Connection Will Not Connect

Oct 24, 2010

I have been running Meerkat in its various forms for the last few weeks. Wireless connection has not been a problem at all. I rebooted about 15 mins ago and on restarting the wireless connection will not connect. I checked to see what the problem was and clicked on Edit Connections and on the wireless tab.

My wireless is set to auto and its name is SKY 24550. I now have 2 entries in the same name and the one that is trying to connect is asking for wep 128 bit security details to be entered. My connection used WPA&WPA2 personal.

Ok, I thought I'll delete the new one (with the different security setting) and try again.

No good, it still asks for the same security details.

So I go back into edit connections and the new one is back again! I can't get rid of it, and while it's there the one that should connect isn't getting the chance.

Fortunately ethernet is working ok and I also have a Natty install which also connects ok through the old wireless connection, but not in Maverick.

Ubuntu Networking :: 10.04 Wireless Connection - Connect To The Access Point

Apr 26, 2011

10.04 in a couple of identical lenovo laptops (of friends) suddenly have stopped connecting successfully to wireless, coinciding approximately with a mains power socket fail at the modem router, now fixed. presumably the machines were trying to connect to the access point, which may or may not have been working, but themodem router was not. Now, internet connection and wireless access point is fixed ok and is back up, and i can connect wirelessly to the access point ok using an eeepc with 10.04.2 with no problem so the access point is working ok

the target laptop/s are still ok via wired ethernet, and can *also* connect to a neighbours open wireless (a british telecom so called fon network, it asks for an account password), and all local wireless networks can be seen normally, and the home access point ssid can also be seen ok. so the aptop wireless is connecting ok, but not to this particular access point now. maybe someting has got screwed up? it is wpa2 and when clicked, after a long-ish time, the authentication is requested, then given, correctly, and still not connecting, asks for authentication again etc etc. no local secure wallet is being used.

when upgrading these laptops for my friend some time ago from 9.04 i have a small recall that 10.04 had a odd thing with wireless authentication (?) bug? i have deleted the network connections gui listing for this ssid and restarted the laptop, still no joy.

Fedora Networking :: Wireless With Inspiron 1501 Bcm4311 Rev01 / Trying To Connect To A Hidden Wireless Network?

I am having a little trouble connecting to my wireless network. Running Fedora 10 32 bit.I'm trying to connect to a hidden wireless network. I updated the firmware for my driver but apparantly the driver is still not working. Broadcom has a driver from their website for Linux 32 bit systems. Should I attempt to install it? I read a post where the driver is built into the system kernel. If so I would need to blacklist the one of the drivers. Correct?

Ubuntu Networking :: Broadcom Corporation NetXtreme BCM5721 Network Card Randomly The Network Connection On The Server Will Stop Working?

Jan 29, 2011

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.

I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
