While I was installing Debian from live-usb, it told me that it can't connect to the wireless network because it has no non-free drivers.So I decided to install the driver later. I downloaded wireless driver from the debian site (in fact, I downloaded the whole pack of non-free firmware.Then I run the command in terminal in su mode:
If the Intel® wireless adapter you are using is listed below, please upgrade your driver to Intel® PROSet/Wireless WiFi Software version = 20.70.0 (or higher version) to resolve the connectivity issues in 802.11ax routers.
Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards.
Firstly, you need to update Broadcom 802.11ac network adapter drivers. Once you have updated the driver, your network connectivity will significantly improve. Besides, this will also help you in offering protection from any probable computer issue shortly.
Upon rebooting my computer, I see my "Ethernet Adapter: No Connection" icon next to my Date/Time on the Taskbar, indicating that my Wireless is "turned off". In Device Manager, it shows a yellow triangle with an exclamation next to my "Broadcom 802.11n Network Adapter" and "NVidia nForce Networking Controller" as well as 3 other drivers listed in my USB Controllers.
I.a. Disable Device sleep on disconnectSome newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as well.Follow these steps to disable this feature on your Nvidia Ethernet Adapter:1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.2. Double-click on Network adapters.3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).4. Click on the Advanced tab.5. Select Device sleep on disconnect.6. Set the Value to Disabled. 7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).
The second manufacturer is who makes the wireless chipset within the card. This is the most important company to know. Unfortunately, it is sometimes the hardest to determine. This is because card manufacturers generally don't want to reveal what they use inside their card. However, for our purposes, it is critical to know the wireless chipset manufacturer. Knowing the wireless chipset manufacturer allows you to determine which operating systems are supported, software drivers you need and what limitations are associated with them. The compatibility section describes the operating systems supported and limitations by chipset.
As of kernels >= 2.6.26 there are mac80211 based drivers which should give better support for almost all Ralink chipsets. As for Ralink 802.11n capable devices, they are slowly gaining support, read here.
This section lists the wireless drivers included in pfSense software and thechipsets those drivers support. This information was derived from the FreeBSDman pages for the drivers in question. Drivers in FreeBSD are referred to bytheir driver name, followed by (4), such as ath(4). The (4) refersto the kernel interfaces section of the man page collection, in this casespecifying a network driver. The drivers are listed in order of frequency of usebased on reports from users.
The RT3090 ral(4) chip is the only model listed as capable of 802.11n onFreeBSD. The RT2700 and RT2800 ral(4) and the RT3900E run(4) hardwareare capable of 802.11n but the drivers on FreeBSD do not currently support their802.11n features.
Finding and installing the correct Broadcom drivers has never been easier, like Broadcom bluetooth driver, Broadcom NetXtreme Gigabit Ethernet driver, Broadcom wireless driver, Broadcom LAN driver, Broadcom network driver, Broadcom 802.11 a/b/g/n network adapter driver and so on.
Same problem here with windows 8.1 and drivers from both Acer and Microsoft for Broadcom 802.11n card in Aspire E1-531. Finally restored laptop to factory settings. I can now connect to Public Networks. Sure wish Acer would fix the driver so I could go back to 8.1.
In the Broadcom wireless installation I was looking at installing the brcmsmac/brcmfmac set of drivers, included with Arch Linux. I neglected the B43 drivers, which should have been obvious since my card model was a BCM4312. lol
Next the right set of corresponding kernel options need to be enabled, based on the drivers and hardware detected previously. The recommendation is to build drivers as modules. Also be sure to enable AES cipher support in the kernel if the wireless network uses WPA or WPA2 encryption.
The search service can find package by either name (apache),provides(webserver), absolute file names (/usr/bin/apache),binaries (gprof) or shared libraries (libXm.so.2) instandard path. It does not support multiple arguments yet... The System and Arch are optional added filters, for exampleSystem could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system. System Arch RPM resource broadcom-wlThese packages contain Broadcom's IEEE 802.11a/b/g/n hybrid Linux devicedriver for use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322based hardware.NOTE: You must read the LICENSE.txt file in the docs directory before usingthis software.
This is a generic driver for the Broadcom Wireless 802.11b/g adapter or Broadcom 802.11 b/g wlan. Many companies use the Broadcom adapter under different names but it is the most commonly used wireless adapter on the market and more likely than not you are using one.
See also the Canon mp250 driver on this website as well as the Common Windows 10 Problems on here. This as well as the CP2104 USB to UART Driver on here as well as the cp2104 driver here. Most times these older drivers are for those who are running older hardware and software. There are still millions of machines out there running Windows XP. There are even many government departments in Asia still running the old Windows XP software out there. The Broadcom 802.11 b/g wlan is no different.
Since I don't own one and don't care much about it I think that it's you that should be in a much better position to provide a driver for it.Anyways I have no freaking clue what the hell your scanner has to do with either ndiswrapper or wireless drivers or the fact that distributions are telling people to remove a working open source in-kernel driver and telling them to use a binary blob.Especially doubly-so that your scanner wouldn't have any sort of kernel driver anyways.

I didn't know people used ndiswrapper for anything other then wifi stuff. Learn new stuff everyday, I guess.Like I said before though, I know that ndiswrapper has legitament uses. It's just that the kernel developers can't afford to have people ignoring open source driver development over binary blobs. However, if they let end users get comfortable with binary blobs then they would end up being forced to support binary only drivers.Intel 802.11g, Broadcom 802.11g, Ti 802.11g, Ralink 802.11g, Realtech 802.11g, all of these things have open source drivers for Linux, but all the time people are recommended to abandon everything except for the Intel for the ndiswrapper driver.If kernel developers sit on this then they are essentially saying:'Hey, your a dipshit if you release your IP (documetation, code, etc) for open source developers to write drivers when end users will just use the windows drivers anyways. Other guys aren't doing it and their stuff runs in Linux just fine, so why should you?' GPL-only symbols and ndiswrapper Posted Oct 26, 2006 23:38 UTC (Thu) by Hawke (guest, #6978) [Link]
Support for running Linux on new hardware -- whether it be motherboards, wireless adapters, graphics cards, or complete systems -- has largely eased up in the past few years. As can be seen from Phoronix reviews of new hardware at launch, in many cases there is Linux support available (e.g. with AMD's launch today of the FirePro V5900 and FirePro V7900 there is already Catalyst support) that continues to be refined over time whether it be in closed or open-source drivers. Even for vendors committed towards delivering open-source Linux hardware support, the path to new hardware enablement is not easy.
Rafał Miłecki, the Polish free software developer who previously spearheaded bringing power management to the ATI KMS Linux driver via a number of patches late last year and into this year, has been working on another project. No, it's not with regard to the open-source Linux graphics stack (unfortunately), but it's on the B43 Linux wireless driver. Rafał has brought support for Broadcom's 802.11n hardware to the B43 driver.
Broadcom wireless network adapters have long been notorious with Linux users since this hardware vendor has not provided any open-source Linux drivers or specifications for their chipsets, even though Broadcom ASICs are dominantly used within today's wireless adapters. There's long been community projects like bcm43xx and b43 to create Linux drivers and use extracted Windows firmware and such to make the 802.11 adapters work, but for Broadcom's new 802.11n chipsets they have made a radical turn and are releasing a fully open-source Linux driver! 2b1af7f3a8
