Ubuntu Networking :: USB Wi-Fi Adaptor For MAC Address Change

Jun 10, 2010

My laptop has an internal Broadcom wireless adaptor. It works fine for basic Internet access, but I cannot change the MAC address with ifconfig. I would like to be able to change my MAC address. Since this is a laptop, the only option for me to do this is a USB wireless adaptor. But compatibility is very hit-or-miss. I've already tried two USB adaptors that had been stated to be compatible with Linux, and while both worked for basic functionality, neither allowed me to change the MAC address.

For whatever reason, this information seems very, very difficult to find. I have spent upwards of ten hours cumulatively searching forums (including this one) and other resources, and have found only vague, outdated, or outright false information regarding USB adaptors that support this. I believe I will be doing a great service to other users like myself by getting this question directly and conclusively answered for once, and the more responses, the better.

Questions:
Do you have (or know of) a USB wireless adaptor that actually allows you to change the MAC address?

If so, what is the specific brand and model number, and what steps were necessary to install the drivers?

Ubuntu Networking :: Can't Change MAC Address

Jan 13, 2011

As I try to change my if0 MAC address either from /etc/networking/interface, or from GUI application, when I try to reconnect (through GUI) the application automatically creates some sort of alias interface with the default MAC every time, and leaves the one with the changed MAC aside.

Ubuntu Networking :: Change To A Static Ip Address?

Apr 11, 2010

I have followed some instructions to change to a static ip address and have now lost my connection to my router. The mistake I made was not copying the original "interfaces" file before making changes.The file originally had: auto wlan0 iface wlan0 inet (something - I thought it was loopback but didn't work when I added it).

The instruction told me to put:
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Which I did, using my own ip numbers, except for "broadcast". I didn't add that in because I didn't have a clue what to put there. When it didn't work, I tried putting it back to what I originally had except I can't rememebr that last bit. I added dhcp instead of what I thought it was but this didn't work either.

Ubuntu Networking :: Internal IP Address Change?

Apr 16, 2010

Now I'm not too clued up about networking and IP addresses. However, I know that I have an IP address for my router (which is dynamic) and then all of my machines have internal address e.g.

192.168.0.2
192.168.0.3
etc...

My server, had the internal address of 192.168.0.4 but now has changed to 192.168.0.7 what causes this to happen? I have to change my port forwarding on my router to allow access to my server from outside my network.

Fedora Networking :: How To Change The Mac Address

Feb 17, 2009

Some people may need to change the mac address of their ethernet network cards. This can be easily done with fedora with command line. Just follow the steps below:

1. Log as root on a textual console (ctrl+F2) or through "su -" command in your console

2. Print your network configuration with ifconfig

[root@localhost ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:23:8B:6A:7E:9E
inet addr:10.1.128.244 Bcast:10.1.255.255 Mask:255.255.0.0
inet6 addr: fe80::218:8bff:fedb:7e9e/64 Scope:Link

[code].....

Here, eth0 is the ethernet interface of your system. The mac address is put in red.

3. Change your mac address using the following syntax

ifconfig eth0 hw ether 00:18:8BA:7E:90

The new value (in green) must be hexadecimal

4. if you have a dhcp server that distributes the adresses automatically, then request a new adress for your eth0 interface

[root@localhost ~]# dhclient eth0

5. Now, your interface is up and have a new mac and IP addresses. This feature may be useful if the network administrator ban you according to the mac adress, for example .........

Fedora Networking :: Change IP Address In KDE?

Mar 26, 2011

I've just reinstalled F14 with KDE rather than Gnome and I'm finding that I'm unable to assign a static IP address to my wired connection.

KDE automatically connects via DHCP, but when I go into KDE's network manager, the eth0 connection isn't listed. In fact, no wired connection is listed. If I manually add one with the correct settings (including a static IP), it switches back to DHCP upon rebooting.

How can I get around this? Should I install the networkmanager-gnome package?

Dec 11, 2010

I purchased a Dell Notebook n4030, that came with the wireless adapter from Broadcom BCM4313. It's been a while since I've been battling with the Broadcom driver to make it work perfectly. I did it!

But some servers I work with wireless in my town and I need to always be changing the MAC Address of my wireless adapter. Whenever I make the change, which is in the Linux distribution is already using it, when I enter the command:

Ubuntu Networking :: Change WLAN0 MAC Address At Every Boot

Jul 29, 2011

change my WLAN0 MAC address in my Kubuntu Natty 64 bit at every boot. I have done quite a bit of searching and found some procedures that appear to have worked back in 9.04 and before days but I have been unable to get anything to work for me in my 11.04 install. I have tried adding a script to if.pre-up.d and also tried adding a bootmisc.sh and either I did them wrong or they are not working. I want to make sure that every time I bring the wireless up in Kubuntu that I have the changed MAC address. I usually keep wireless disabled and turn it on just when I need it.

Background so you don't think I am doing something nefarious... I am going on a cruise soon. The cruise line sells wireless internet subscriptions for the duration of the cruise but they tie it to a MAC address. I am bringing my CDMA android phone that unless I use VOIP will be unable to call at all or at least with very high charges. But I also want to be able to browse the internet with my laptop. I figure it will be easier to spoof my phones MAC with the PC than the other way around. I just need to turn one device off if I am using the other. I need the MAC address to be semi permanent so I don't turn it on by mistake and have forgotten to change the MAC.

Networking :: Can't Change From Dhcp To Static Ip Address

Jan 16, 2010

Can't change from dhcp to static ip address.I've installed Oracle's version of Linux Redhat 5, but I'm having no success changing from dhcp to a static IP address. My machine is plugged directly into a Belkin router which has the IP address: 192.168.2.1.If I use the gui: /usr/bin/system-config-network and set the network device to dhcp,it works fine. But if I set the IP address manually, I get no internet traffic, and if I ping an internet website, "network unreachable".The installation instructions for Oracle say that they want a full domainname. I've tried gateway.2wire.net. This worked in the last place I did a successful installation.It was the address of my ATT router. If I plunked that into a browser, I got the router configuration.

Ubuntu Networking :: Change Ip Address Of Second Internet Sharing Network Card?

Sep 2, 2010

I have a second network card in my ubuntu desktop that I have sharing my internet connection with a wireless router. I have set the router to a static ip address within the network cards range. But, every time I restart the computer, the network card uses a different ip address. One time it will be 10.42.43.1, the next time it will be 10.42.46.1, ect. This makes me have to hard reset my router every time it does this. How can I set the network card to use the same ip address all the time?

Ubuntu Networking :: Change The Proxy Settings And Put In The IP Address And Enter The Port To 3000?

Nov 8, 2010

My college providers shifted to a different setting.. I'm not sure what needs to be done. On windows, under the connections tab you need to change the proxy settings and put in the IP address and enter the port to 3000. Questions:

1. where lies the linux (ubuntu 10.04) variant to execute the operation.

2. What can be the major obligations of such a change?

I am sure its siimple enough, but I can't get my net to work properly. The connection provided to the internet is through wireless routers.

Firstly, apologies if there is anything incorrect about this request for help. Consider me an intelligent but ignorant first time Ubuntu user. I have a USB wifi adaptor, [URL]../B...ef=oss_product, which claims to be Linux compatible. It was supplied with a CD that includes a Linux directory but windows-only documentation. How do I install the drivers etc, the device is currently entirely unrecognised by Ubuntu 10.04.

Ubuntu Networking :: Get Wireless Adaptor To Work?

Aug 6, 2011

I have a older Dell desktop running a older version of Ubuntu 9.04. I recently got a Belkin N300 micro wireless usb adaptor so I could use it to connect to the internet. I have a Verizon MiFi 2200 wireless router that I use for internet access. The desktop won't recognize the new hardware. It came with a driver disc, but it's for windows.

Will this adapter even work with linux?

If so, how do I get it to work?

Ubuntu Networking :: Unable To To Access Wireless Adaptor

Apr 16, 2010

I set up an older computer with Ubuntu 9.10 and tried to get my Linksys AE1000 Wireless N adapter to work. My first mistake was not checking in advance to see if this adapter would work, but I have taken the leap and I am intent on making it work. I ran lsusb and it gives me a device number (13b1:002f) so I know it can be seen and I have also installed indisgtk the GUI for Wirless drivers. I have tried some suggestions from other posts to no avail.

Ubuntu Networking :: USB Wifi Adaptor Loses Connection Every Few Minutes

Apr 22, 2011

I just installed the Natty Beta and plugged in a Netgear WG111v3 USB wifi adapter. It is using the RTL8187B driver and worked out of the box. The problem it loses my connection every few minutes. Sometimes not for 10 or 15, sometimes like a minute or less. After it loses the connection, I have to uncheck "enable wireless" (which I assume is the equivalent of bringing down my wireless interface) and then check it again before it will let me reconnect. I don't want to try ndiswrapper because the card works great when it works, including monitor mode and packet injection!
