Ubuntu Networking :: When Type In WPA2 Password It Will Not Authenticate With Linksys WRT-54GL Router?
May 12, 2010
Well this one is driving me nuts. I've been searching through the forums for a while and it seems that a number of folks have similar issues but the solutions used don't look like they apply to me. so without further ado here are the outputs typically requested:lspci
00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 03)
Im trying to setup a radius server to use WPA2-Enterprise on a linksys wireless router. I have so far done the following from this link: [URL]... Im having trouble understanding/finding information on how to configure the configuration files so my radius server will work when somebody tries to authenticate.
I followed these instructions to setup my wusb11 driver using ndiswrapper:
But when I try to ifup the interface, I get:
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4 DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10 DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 14 DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3 No DHCPOFFERS received.
iwconfig shows that no essid is assigned, even though I have specified one in /etc/interfaces.
Then if I go through the desktop gui Preferences -> Network to setup my wireless connection, /etc/interfaces does not seem to change but iwconfig then reports the essid is assigned.
Anyway, on my default taskbar there is a wireless icon. Clicking on that shows the wireless access points in the area. I see my own. When I try to connect to it, it prompts for my wep key. I enter the key, it thinks, and then acts as if I'd entered the wrong key.
Specifically of course, I'd like this to get fixed so that I can happily surf the net again, etc.
But I also I'm wondering why it seems that there is a disconnect between /etc/interfaces and Preferences->Network. If I type in a WEP key in the gui, I would think that it should appear in /etc/interfaces.
I'm definitely a Ubuntu wireless newbie, and not very experienced at Ubuntu anyway.
Using a D-Link wireless router, trying to get it through the authentication process with the client through a D-Link DWA-125 USB wireless. When I set encryption to "none" on both ends, the router links up OK, but when I enter matching encryption settings on the router, and then in the driver data file (RT2870STA.dat) on the client side, I can't get it to authenticate. I've tried all possible combinations in the .dat file with no luck. I'm fairly well convinced that there is a bug in the .dat file settings, and that the wireless port setting need to be forced at startup through the /etc/networking/interfces file, or some such procedure, to override the settings in the .dat file.
I've been having a network problem that I've been able to temporarily solve by rebooting the router, but even that can be shaky at times, and it can sometimes disturb others' internet activites, so I'd really like to tackle this while I can. I had an old thread about this, but it's ancient history by now, and plus which, I've got a bit more Linux experience and patience than I did before.
The basic problem is that NetworkManager will associate and connect to my home wireless network, but a) it won't let me ping the router or anywhere else ("Destination Host Unreachable"), and b) the connection lasts for maybe a couple minutes at most. If I reset the router, however, 9 times out of 10 it will associate and connect successfully and I can get online, but I have to run a constant ping to the router with a 10-second interval, otherwise it drops the connection, unless I'm doing a lot of other heavy network activity.
ping 192.168.1.1 (the router):
I've tried wpa_supplicant, but this is what I get (it's apparently unsuccessful...? ESSID/MAC addresses censored where necessary):
The last prompt line is included because I cancelled it myself; it didn't abort on its own. If left unmonitored, it basically keeps doing this over and over, with no visible network activity at all.
With NetworkManager, I can keep selecting the network's ESSID over and over, and it seems to reconnect, but I still can't ping out anywhere. I'm using a Netgear WN111v1 wireless adapter with ndiswrapper and the Windows drivers. I have no idea what the chipset is, and I doubt that Linux drivers exist for it, even if I knew what it was. The router is using WPA2 security (hence my trying wpa_supplicant)
ifconfig wlan0 (while connected; IP/MAC addresses censored where needed):
ifconfig wlan0 (while not connected; IP/MAC addresses censored where needed):
I only include this for format checking purposes. The commented out "psk" is the actual text passphrase, while the uncommented one is (presumably) a hex representation of the same key. Is this correct? I've never done this with wpa_supplicant before, I've only used NetworkManager (which is a pain in the @$$ because it requires X to run, and so it disconnects any time I log out/back in ).
Is there any hope of getting my wireless connection permanently working, so that I don't have to reset the router every time I need to reboot or log out/back in?
I am dual booting XP and Ubuntu 10.10 64bit on a Dell Latitude E6410 and I have a Linksys WRT120N router connected to my Modem.
So the weird thing is, under XP I can use the internet while connected to my router. Under Ubuntu I can't use the internet while connected to my router. But I can use the internet in Ubuntu if I connect to my neighbor's router called "linksys". So something happens when I connect to my router that makes Ubuntu not able to access the internet. But if I'm connected to my Neighbors router or if I use XP while connected to my router I can use the internet.
I have been using Ubuntu for about a year, so I'm getting better but still a noob. I've tried to figure out what's going on by looking at other forums and posts and trying to see if anyone has solved this. So far I've had no luck. This is also the first of many problem I have encountered that I have been unable to solve using online posts, and is the first problem that I have had to resorted to creating a post to try and fix.
I have been using the B version for many years, just got the G version for a B-day gift. I run OpenSuSE 11.3 and XP on one computer but I have several (3) wireless laptops in my house plus a xbox wireless. I also have 2 other ethernet computers connected to the B version. Can someone provide me with some links/info on how-to. When I did a Google search all I came up with is firmware upgrade...which I've done for the B version. Is it as easy as taking out the old...configuring the new?
I set up my linksys router for PPPoE and username, however, if the compter goes idle after a while, I have to go back into the configuration page, save settings and everything is ok. I would like to keep the connection alive 24/7. There are two settings: time to live (max idle time) redial Max idle time is now set at 10 minutes. The redial is grayed out. Are these the settings I should be concerned about?
Okay, a few days ago I got a small job setting up a router for a neighbour of mine. He wanted me to set up a wireless network for him. The router he bought is a Linksys Wireless N-Router E1000. I set it up the passwords and everything. Only to find out that I couldn't connect at all to it. The main computer with a direct ethernet connection to the router was the only one that had internet. Everytime I attempt to connect wirelessly with any device, it will take extremely long time to connect, to the point where I will just quit connecting.(Example: 15 minutes of waiting, when the laptop is right next to the router)
Any ideas about what I am doing wrong here? As far as I can think of it might just be a faulty router, because the router will not implement any changes(like setting a password) I set on it. Only wired connections seem to work. the router is called a linksys wirless N-router E1000.
I have an Acer Aspire 1 Netbook - this is running UBUNTU- When I try to connect to my Linksys Router in wireless mode it asks for password - but doesnt accept. I can see the Linksys in network manager plus several other networks in the vicinity. My other wireless devices all connect O.K. to the Linksys, and accept my password.. I can hard wire by ethernet to the netbook. Just wireless is the problem
i installed ubuntu 10.04 from internet.but i cant connect to my wireless router linksys wrh54g ver 1.0,but if i using Local area connection its working,however my wireless connection working in my other os win xp.
I have a Linksys WAG54G2 Router - this is set up and was working fine with Xp and my Apple I phone.I have just changed over from XP to Ubuntu, and am having difficulty in configuring wireless settings to accept UBUNTU.The hard wired Ethernet connection works fine.
I have a linksys router in my basement and physical access is pretty much blocked by a stuck trap-door. I could try to shut off the main power switch, but I like to see that as a last resort. The problem I have is that I have an open (no encryption) wifi connection between my pc and linksys router, yet I cannot connect to it. Until a couple of days ago I could connect to it with my android handheld device, my linux laptop, and my windows desktop. All these devices are now unable to connect. I attached the wicd log from my linux laptop. How to gain access to my router again?
I am running Fedora 13 and I have a linksys WRT54G wireless router [1,2]. I'm having a strange problem. I'm using a computer connected to the router via a wired connection. At intermittent moments the connection seems to stop. I can't even ping the router (192.168.1.1). However, if I make NetworkManager reconnect to eth0 the connection immediately comes back and I can ping the router and navigate to websites. If I wait a random amount of time the connection also seems to comes back on its own (without reconnecting via NetworkManager). Any idea if this is a hardware (router) problem or a software problem? This didn't happen a month ago.
P.S: I have already updated to the latest firmware (Ver.8.00.8).[URL]..
I am running Ubuntu 10.04 on a PackardBell notebook and have just got an Orange Livebox 2 for broadband connection(after years of dial-up as no adsl in my area).I am trying to connect via WiFi to the Livebox to configure, but neither NetworkManager nor Wicd will connect. NM sees the Livebox but simply fails to connect after trying; Wicd says "Bad password".The WPA2 password I have entered is definitely correct, and I have connected without any problem from an AcerOne under Linpus.I have also tried to connect using Wicd and an ethernet cable, and this doesn't connect either, returning "Connection Failed: Unable to Get IP Address"
After I installed a gigabit router, I could not access my nfs server anymore; I tried with the previous physical set-up and all was OK so clearly it is the new router that is the disturbing factor. After some (and then some) experimenting, it would appear that the following specific feature needs to be enabled: Filter Internet NAT Redirection This feature uses port forwarding to block access to local servers from local networked computers. Select this feature to filter Internet NAT redirection. It is not selected by default.
The reason I had simply looked over it is that I did not see how internet nat redirection could be related to the local network. As I read the details, it became clear that it really is but it also raised new questions. Have I now allowed just anyone on the internet to access to my nfs server? Because the description is not very clear either as it mentions both internet and local network. And what is that odd terminology? Filtering allows access, not filtering does not - that seems like the world upside down ...
Its seems Fedora 11 on eee pc 1000h cannot connect to any wireless type(Open, WPA2, WPA or WEP) of a hidden network(non broadcasting SSID). Though it can connect to visible ones(broadcasting SSID), since my college is on a hidden network this a problem for me. Though I can't really test if its just fedora 11 or rpmfusion drivers for it 1000h model related problem.
hello i am trying to change my password, but when i type in the new password i get this:"The password is longer than 8 characters. On some systems, this can cause problems. You can truncate the password to 8 characters, or leave it as it is."my question is what kind of problem could i get and how can i change so i have to log in every time i start the computer?
When I start my laptop, the network manager tries to log on to my home network, apparently fails, and then brings up a screen offering me a space to enter the password for the home WPA2 network it's discovered.
Whether I enter the password when prompted or go into "Network Connections" and edit the password there the system always offers up a seemingly random 64 character string of numbers and letters instead of the true password. What's going on and how do I fix this?
new to ubuntu and having difficultly connecting to my wireless router.It can see the router but will not connect keeps asking for password.usb adapter is working 100% as i can connect with it using xp 64bit.
I have a Vizio router, I run Kubuntu 10.10, I set my Kwallet password to blank, but Knetworkmanager keeps asking for the router password (WPA2, 10 digit random). I tried Wicd as well; both of them have the same problem.
