If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter Zinwell Technology, Inc. ZWX-G250 into the search box above and then submit. In the results, choose the best match for your PC and operating system.
Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.
This answer is based on an extensive research done by various Ubuntu users that worked together in almost all issues related to Broadcom. Special thanks to chili555 who helped in the Ubuntu forums and on this site with many questions related to Wireless devices and to others who have contributed through E-Mail, chats, IRC and more in testing various drivers with several of the most popular Broadcom Wireless cards (Huge Thanks to Chili555 really. This guy knows his stuff).
In total we wanted to offer an answer that could be easy to follow and covered most Broadcom Cards / Drivers. After you follow this guide, you will NEED to test your wireless connection for at least 2 hours (I actually recommend 8 hours) with another device in either Ad-Hoc Mode, Infrastructure Mode or Both. Common problems that will be solved (Apart from drivers not installing) are:
There are dozens of Broadcom wireless cards and more seem to appear every day. The key to finding the correct driver for any network card is what is known as the PCI ID (PCI.ID). To find out which PCI.ID you have, we proceed to opening the terminal by pressing CTRL+ALT+T (It should open a window with a blank background) and inside this terminal we run the following command:
With this new information you can look in the table below and select the appropriate method to install your driver. For example, In this case, since you have the 14e4:4320 rev 03, if we go down the list to the one that shows the exact same PCI.ID you will see that in the columns for Ubuntu 18.04 or 20.04 it shows the firmware-b43-installer package driver. This means that you will only have to install this particular package since it appears in all Ubuntu version columns.
NOTE - Before proceeding, if you have previously installed any drivers, have blacklisted or uncommented any driver files or configuration files or have done any changes whatsoever to the system to make the drivers work in previous attempts, you will need to undo them in order to follow this guide. We assume you are doing this from scratch and have not changed any configuration files, modules or drivers in the system in any way (apart from updating the system). This includes any installations using apt-get, aptitude, synaptic, dpkg, software center or manual compilation and installation of the packages. The system has to start from scratch in order for this to work and to avoid any conflicts that may appear if earlier work was done.
Now using the PCI.ID you found in the steps above, we then search in the list below to find the matching PCI.ID and the method to install the driver associated with it in a simple and correct way. The terminal will be used to avoid any GUI related issues. This applies with all cases, except as noted. The installation procedure is done only via terminal and also while connected to the internet with a temporary wired ethernet connection or USB modem or any means possible that can give your PC, for the time, Internet access. After you find in the list below the correct package we then proceed with the installation.
Assuming you used the PCI.ID 14e4:4320 rev 03 as found in your search above, and then looked at the table below and found that the correct package to install is the firmware-b43-installer (Specific to Broadcom) and the linux-firmware (Carries over Broadcom related drivers along with other types of drivers), we then proceed to simply install this package in the terminal:
For All cases, always install the linux-firmware package. This will always be up-to-date with the latest Broadcom drivers along with other binary files that could be needed depending on the driver PCIID.
IMPORTANT NOTE - After September 2014, if you follow this answer and still you have problems installing the correct driver, please try the firmware-b43-installer package and the linux-firmware package and notify us via comments. There were some changes and some drivers will only work with this package. Remember to have a clean system before installing it:
In some computers, before performing the commands, you will need to deactivate the Secure Boot Options in your BIOS. This applies for cases, for example, where the bcmwl-kernel-source is already installed but the driver does not yet work. You can do a reinstall like so, or disable Secure Boot by going to your BIOS Setup:
The following information is additional material to read about solving various issues related to Wireless Management and conflicts with other Network devices. Know that it some cases you need to have an updated Kernel version, since each new version of the Kernel introduces either new Network drivers, improvements over existing drivers or solves bugs regarding them.
For all Wireless cards in general, it is very important to also take into consideration the network devices you are using (Routers, Switches, Wireless Channels and Wireless Bands, etc..). With this information you will be able to evaluate better what the source of the problem could be when you arrive at a dead end. An example would be the Lenovo S10-2 which uses the 14e4:4315 rev 01 PCIID. Even after installing the correct driver the user would end up in a "trying to connect" loop. It would see the wireless SSID but when trying to connect to it, it would enter an reconnecting loop.
This is because the access needed is denied by Secure Boot so the drivers will look like they are installed correctly when in fact the did not. So for VERY specific cases, you will need to temporarily disable Secure Boot in order for the drivers to work.
brcm80211 aka brcmsmac. This is a (relatively) new driver that was recently added to Ubuntu (since the driver was added to the kernel). This should work well and (in recent version of Ubuntu, Natty and Oneiric) should "Just work". This is the droid you're looking for. Use this driver for the 4313.
If you're not running Natty or Oneiric, your kernel probably won't have this driver. You need to be running at least 2.6.27 and I'd recommend 2.6.28 as the bare minimum (you can check what you're on by running uname -r). 2ff7e9595c
