Ubuntu Networking :: Router Encryption Settings 10.04 - Can't Authenticate

Nov 27, 2010

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.

Ubuntu Networking :: Wusb11v4 Sees Router Cannot Authenticate Wep

Jan 17, 2010

I'm getting rather bewildered.

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 port 67 interval 4
DHCPDISCOVER on eth0 to port 67 interval 10
DHCPDISCOVER on eth0 to port 67 interval 14
DHCPDISCOVER on eth0 to 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.

Networking :: Cannot Ping Wireless Router Or Access Router Settings - Wireless ?

Jun 9, 2010

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.

I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.

So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page ( times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?

Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.

We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.

Ubuntu Networking :: Wireless Card - WEP Encryption For Wireless Router Not Allow Me To Connect

May 5, 2011

wlan0 Authentication capabilities :


Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.

Ubuntu Networking :: Router : No Connection After Modifying Port Forwarding Settings

Sep 2, 2010

what I have: Belkin G Wireless Router Model F5D7234-4. To attempt to get Subsonic working, I changed the port forwarding settings (Belkin calls it Virtual Servers) to forward port 4040 to my desktop computer. I then saved changes, and my wireless disconnected. I waited about 3 minutes, and nothing was happening, so I restarted my router. This left me in the position that I am in now. Even when the router and modem are fully booted, the router does not broadcast my SSID. In addition, a wired connection will not connect to the network through the router. This leaves me completely unable to use wireless, and unable to change any settings in the router.

Ubuntu Networking :: 10.4 - Cannot False Authenticate With AP

May 13, 2010

I'm on ubuntu 10.4 and Cant seem to falsely authenticate myself with my AP. I am trying to break a wep key on one of my older linksys routers; It continues to say this:

root@kevin-laptop:/home/kevin# aireplay-ng -1 1 -a xx:xx:xx:xx:xx:xx mon1
No source MAC (-h) specified. Using the device MAC (xx:xx:xx:xx:xx:xx)

11:39:42 Sending Authentication Request (Open System) [ACK]
11:39:44 Sending Authentication Request (Open System) [ACK]
11:39:46 Sending Authentication Request (Open System) [ACK]

Attack was unsuccessful. Possible reasons:
* Perhaps MAC address filtering is enabled.
* Check that the BSSID (-a option) is correct.
* Try to change the number of packets (-o option).
* The driver/card doesn't support injection.
* This attack sometimes fails against some APs.
* The card is not on the same channel as the AP.
* You're too far from the AP. Get closer, or lower the transmit rate.

I'm using an eeepc 701 it has an Atheros card and does injection. I have also tried it with backrack 4 and it works perfectly (it falsely authenticates with the ap and decrypts the wep key) I just cant seem to get it to work on ubuntu 10.4. Could it be a kernel issue? I found out that there is a bug in the new(er) kernel(s). If you use an older kernel (I used 2.6.31-14 which can be found here) and it magically works.

Ubuntu Networking :: Cannot Authenticate To WPA Network

Aug 22, 2010

I have a TP-Link Atheros-based USB card: TL-WN422G. It's listed widely as being compatible, but I'm baffled if I can make it work. I'm running an ndiswrapper (XP-64) driver, and that seems to be loaded and recognizing the hardware correctly. The system can scan and correctly identify our network, and other nearby ones, but when the WPA key is entered (correctly, I've triple checked), the "Secrets" windows just keeps popping up and no IP is acquired. I've installed and tried to configure it with wpa-supplicant, all to no avail.

Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?

Jun 18, 2011

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.

As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?

My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

Networking :: Set Up A Laptop As A Router To Connect Wirelessly To ADSL Router?

Nov 6, 2009

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).

I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.

I have added this to /etc/sysctl.conf on the laptop:


Then I tried this on the laptop:

sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT

This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.

But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

Networking :: Network Setup - Router - Wireless Router Card ?

Apr 24, 2010

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.

Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.

Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).

The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.

Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from (itself) to, while the wireless router card assigns addresses from to (itself).

Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from to, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.

Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E.,,

My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

Ubuntu Networking :: Samba Server - Authenticate With Passwords?

Jan 2, 2010

True or False: If you have a user on your Linux/Samba machine with a password, example:
User = Bob
Password = Password0
And Bob is on an XP computer, where his username is also Bob and his password is also Password0, is it normal for Bob to go to:

\SambaServer, double click on Bob's share (valid users = Bob only) and Bob get RIGHT in without being prompted?

On my prior setup, the user HAD to log in. If they wanted auto login next time with their credentials, they had to check "remember password." But now it's as if Samba knows who they are. It's very strange. What's the normal behavior? Must EVERYBODY authenticate with passwords, or if the Windows credentials are the same as Samba does it just somehow auto-detect it and allow them through?

I acquired an old Compaq Evo laptop and installed Kubuntu on it. Bought a second hand wifi card, a DEXLAN IEEE802.11b (Having Googled to check it would work with Linux).

It detects wireless networks fine, and is able to connect to open ones, but I can't log into the home network with the password which works fine for Windows laptops.

I've tried every configuration of the router I can find, and followed the advice at https://help.ubuntu.com/community/Wi...untu#EasySteps but with no luck. It just asks for the password over and over again without connecting.

Networking :: Cannot Seem To Authenticate A Wireless Laptop

Dec 6, 2010

We've got a Debian Lenny + FreeRadius and cannot seem to authenticate a wireless laptop.At this point, all I want is the users file entries to work, with ClearText passwords. Eventually we'll use LDAP but we want this up first with ClearText passwords and MD5.

1. FreeRadius installed, 2.1.10+dfsg-2~bpo50+1 from Debian Backports
2. AirPort v7.5.1, set up for WPA2 Enterprise, ip
3. Apple OSX laptop, 10.5.8

When running 'freeradius -Xxx' from the Debian cli I can see the authentication fail as though the OSX machine (or the AirPort router?) isn't passing along the password (from the FreeRadius cli run).Additionally, the OSX machine always prompts me for an SSL Cert to use, but with MD5 checkmarked as the only option in the 802.1x networking screen, this shouldn't be happening, making it more difficult to tell where this problem lies.The OSX machine keeps cycling through "Authenticating" and "Authenticating with MD5", and then settles on "AirPort has a self-assigned IP Address..." (meaning the laptop, not the AirPort wifi router)
