Few years back one of the main factors that stopped me from installing Linux on laptop was the Wi-fi support. Many prospective Linux users might have apprehension about installing Linux because of this legacy. One thing that you have to keep in mind when you start using Linux is that tomorrow will be years ahead of today in open source world. So buy the time you actually start using wi-fi, somebody somewhere might have developed the necessary driver usually by ingenious reverse engineering.

So here i have compiled various Laptop(wi-fi) providers and there Linux support sites and few comments

DELL(Broadcom)

Dell, with some help from Broadcom and Canonical, the company behind Ubuntu, has released a Linux friendly Broadcom Wi-Fi driver for both 32 and 64-bit Linuxes. For Dell users, this means that they now have Wi-Fi support for the Dell 1490, 1395, 1397, 1505, and 1510 Wireless cards.
So Dell Studio series and Inspiron Series will work.The drivers should work with any Broadcom card using one of the supported chipsets on any modern Linux

Download Driver-Direct Link

Support for Opensuse 11.x

Atheros

If you use Wi-Fi on your laptop, there’s an excellent chance you’re using Atheros chipsets for your wireless networking. Atheros’ silicon is in gear from Linksys, D-Link and Netgear to name but a few vendors.Atheros does a reasonable job to support Linux drivers. he MadWiFi driver for Atheros wireless cards are not included in the distribution as its HAL module is only available as proprietary. However, it is  possible to use this driver.

Opensuse Link -Excellent Explanation

Intel

Drivers for the Centrino,2100/2200/2915 devices can be found in  recent kernel so it is not necessary to install it seperately. It will be working out of the box for kernels after 2009 Jan

Acer (ATMEL)

These cards are also natively supported and hence should not be problem.

Efter att ha installerat Ubuntu 9.10 Karmic Koala märkte jag när jag försökte föra över filer från en dator i mitt hemätverk till min egen dator att nätverksanslutningen var väldigt ostabil. Faktum är att den var så ostabil att det var omöjligt att föra över större filer. Överföringen avbröts då och då.

Så jag började kolla runt lite på nätet efter en förklaring till varför min trådlösa anslutning var så ostabil, och även efter en lösning till problemet. Jag hittade båda.

Anledningen till att anslutningen var så ostabil var att (som jag förstod det hehe) ath9k drivrutinen associerade och disassocierade hela tiden. De flesta som hade problemet verkade köra kernel 2.6.31 (vilket är standard i Karmic). Man fixade det enkelt genom att installera linux-backports-modules-2.6.31-14-generic.

Så efter att ha installerat det paketet, och startat om datorn, var min anslutning stabil igen och jag kunde föra över filer mellan min dator och andra datorer i nätverket utan att överföringen avbröts. MEN, jag märkte även en annan stor förbättring. Den trådlösa signalstyrkan hade höjts med ca. 20-25% mer än vad den brukade ligga på, och när jag gjorde ett hastighetstest hos bredbandskollen.se fick jag nu exakt lika bra upp/ned hastighet i Ubuntu som jag tidigare fick i Windows XP!

När jag exempelvis sitter på mitt rum, ca. 8-10 m från routern, fick jag förut (efter att ha ställt in routern på 802.11 b/g) ca. 6Mb/s ner i Ubuntu och ca. 10Mb/s ner i Windows XP. Nu får jag alltså ca. 10Mb/s även i Ubuntu! En ökning på 4Mb/s:D

Blev så glad tack vare det att jag nu tagit bort Windows XP helt och hållet och endast kör med Ubuntu.

Så, om du har en svajjig, väldigt dålig anslutning, med ovanligt låg signalstyrka på din dator med Atheros nätverkskort som använder sig av ath9k drivrutinen i Ubuntu, installera linux-backports-modules-2.6.31-13-generic och problemet är löst.

Se você gosta de você mesmo, recomendo que leia todo o artigo, pois você economizará tempo, saúde e dinheiro. Ajudarei a não se arrepender do que comprou. Resumindo, o que importa é a marca e não o modelo.

• Não compre placa-mãe com chipset VIA ou SiS, pois são os piores e não terá aceleração 3D, ou seja, nada de efeitos legais. No caso do chipset SiS nada funcionará direito.
• Não compre notebooks baratos da Positivo e CCE, pois os dois não funcionam no Linux (mesmo que eles venham com alguma distribuição Linux).
• Não compre computadores em supermercados, pois você não pode personalizar e os vendedores não entendem nada de nada.
• Não compre o computador mais bato da loja, não seja iludido pela quantidade de memória ou HD, são tão baratos que se for realmente necessário você poderá comprar depois.
• Não compre placas de vídeo ATI (de acordo com os boatos, os drivers são mal feitos).
• Não compre webcams que não possuam o selo “Compatível com Windows Vista” e pergunte ao vendedor se para instalar no Windows Vista precisa da algum driver, se precisar de driver, não compre.

Agora que você já sabe o que NÃO pode comprar, agora vamos para o que você PODE comprar.

• Primeiro, e o mais importante, só compre computador com chipset Intel, pois fará que tudo funcione automaticamente (a Intel contribui e muito para o kernel Linux, por isso tudo funciona perfeitamente), mas se você gosta de AMD o jeito é uma placa-mãe com chipset ATI ou NVIDIA (que na maioria das vezes precisam de instalar um driver para funcionar o 3D, mas dê preferência ao NVIDIA).
• Se você gosta de jogos, compre uma placa de vídeo NVIDIA.
• Se você usa internet via rádio compre uma placa de rede sem fio com chip Ralink, Realtek ou Atheros.
• Só compre impressoras HP.

Desta maneira você tirará o melhor proveito do seu Linux, tudo automatizado, ou seja, parecerá que o mundo da informática é perfeito. Acima falei sobre as coisas que podem causar os problemas mais comuns e a melhor marca:

• Placa-mãe: chipset Intel
• Placa de vídeo: NVIDIA
• Webcam: 100% compatíveis com o Vista
• Placa de rede sem fio: Ralink, Realtek ou Atheros
• Impressoras: HP

Nada substitui uma boa pesquisa ou experiência própria, mas não confunda coincidência com a realidade, ou seja, se a maioria dos produtos de uma empresa não rodam bem no Linux, não arrisque comprar, pode dar errado. Você pode estar pensando que se montar um computador seguindo tudo que está neste artigo o mesmo ficará caro, mas isso não é verdade. Um bom computador deve custar no máximo 30% a mais que o computador péssimo (estou falando de um computador com a mesma quantidade de memória, HD, etc. O que muda é a qualidade e o melhor suporte ao Linux ou até mesmo ao Windows).

Exemplo: se um computador péssimo custa R$ 1.000,00 um bom custa R$ 1.250,00 (com a mesma quantidade de memória e HD). Esse é o preço da qualidade. O mais provável é que você só consiga montar um computador bom se NÃO comprar em supermercado, pois assim você poderá escolher peça por peça.

Se você for comprar uma novo hardware para seu computador que não consta neste artigo e você tem certeza que a maioria do computadores não tem, pesquise antes ou peça ajuda em fóruns. Caso não tenha entendido tudo que eu disse, imprima esse artigo e mostre para o vendedor de uma loja de informática e ele fará um orçamento para você, nesse momento é que se escolherá a potência do seu computador, mas não esqueça do que eu disse: o que importa é a marca.

In the previous post, we looked at Infineon’s strengths in wireless. However, Infineon’s portfolio is still incomplete in the area of connectivity solutions, which are playing a major role in the convergence trend.

Infineon remains a minor player in Bluetooth. Infineon lacks much of the IP related to connectivity solutions. Infineon’s Bluetooth and GPS solutions use third-party software stacks. As a result, Infineon does not offer any combo chips for connectivity. There are none promised in the future, either. Most other major vendors offer combo solutions that provide space and power consumption savings.

After Broadcom acquired Global Locate, Infineon had to look elsewhere to offer a GPS solution. The company now partners with Epson to offer a GPS/A-GPS solution. Xposys integrates Epson’s GPS expertise with Infineon’s renowned RF know-how. Xposys has been winning praise for its higher sensitivity and lower power consumption. However, Xposys is a software-based GPS solution and its success depends on performance in the real world.

Lost Chance

Because Infineon’s deficiencies in connectivity extend beyond GPS, it could have partnered with the likes of Atheros with presence in multiple connectivity technologies. Infineon has near zero presence in the fast-growing wireless LAN market. Infineon’s play in WLAN for mobile devices is limited to providing Low Noise Amplifiers and RF transceivers. Infineon’s earlier plan to provide Atheros’s Wi-Fi solution alongside its baseband was not successful. This was bad execution considering that a similar approach by Qualcomm had worked, and Atheros’s Wi-Fi solution has been shipped in a multitude of dual mode 3G designs. Atheros provides solutions for all major connectivity options: Wi-Fi, GPS and Bluetooth. With their complementary portfolios, Atheros and Infineon would have made great partners. The combination would have had a complete portfolio except for an application processor. Alas, with Infineon partnering with Epson for GPS, such an alliance is unlikely now.

Application Processor

Another important piece of a mobile phone that is absent from Infineon’s portfolio is the application processor. Flash memory is the most expensive piece of silicon in a mobile phone. Where they are discrete parts, application processor is in a close race with baseband IC for the second spot on a BoM.

In the iPhone, its most popular design win to date, Infineon’s baseband processor and RF transceivers work in conjunction with Samsung’s (or is it Apple’s own?) application processor. Even if speculation of Apple working on a home-grown application processor proves to be false, Apple is unlikely to switch to a combination application processor+baseband processor approach anytime soon. Performance is at the heart of iPhone, not cost concerns. Infineon might be able to hang in there for a little longer.

Infineon could lose if Qualcomm’s efforts to have a piece of iPhone hardware were to bear fruit. It would be interesting to see if Qualcomm can entice Apple with an irresistible part. This is more likely with a combo communication processor, if Apple were to introduce a lower-priced, reduced performance model in the iPhone lineup. In the meantime, Infineon should partner with an application processor provider to be able to complete with other major players.

In sum, the lack of internal IP for complete connectivity and of an application processor will hurt Infineon’s chances of design wins. Partnerships are necessary to close the holes and provide complete platform solutions.

Atheros, a Wi-Fi chipmaker, said today it’s agreed to buy Intellon, a maker of chips that turn the home’s electrical network into a conduit for broadband, for $244 million. While most of us use Wi-Fi for our home network, it needs a stronger — and more reliable — wired infrastructure to aggregate and move the ever-increasing amount of HD video streams, music and telephony around. Which is why Atheros CEO Craig Barratt, while discussing his company’s proposed acquisition of Intellon on a call with financial analysts, described powerline networking technology as the backbone of the home network.

Indeed, today’s announcement makes clear that Wi-Fi is not everything to everyone. Of course, Intellon’s strong gross margins and talk of sequential quarterly growth helped endear it to Atheros (and to the analysts on today’s call) as well. Intellon said in July that gross margins for its most recent quarter had exceeded 50 percent, and that revenues had increased 14 percent on a sequential basis. Intellon has done well selling its powerline chips into the European IPTV market, and has seen increasing interest in them for smart grid applications.  It’s also been hawking Ethernet over coax solutions into China, and has been investing in the upcoming G.hn wired home networking standard.

Given all this, the combined company will be positioned strongly for the future, as more carriers in the U.S. and in other markets look for both wired and wireless network capabilities to integrate into their residential gateways and set-top boxes in order to move digital content throughout the home.

So what does this acquisition mean for other Wi-Fi providers? Most will need a wired solution to leverage in-home wiring, such as coax or powerline. While Broadcom has already made a big strategic acquisition of MoCA (coax-networking) provider Octalica, this move by Atheros might pressure the company to shore up its powerline technology, especially given that MoCA is largely a U.S.-centric play. Other HomePlug players include Gigle Semiconductor and Coppergate (which acquired the HomePlug assets of Conexant), while Spain’s DS2 offers a competing powerline technology in UPA.

One way or another, the home network will continue to evolve, as I wrote about in a recent analysis over at GigaOM Pro (subscription required). In the meantime, Atheros’ acquisition of Intellon is just more proof that we are indeed moving towards the vision of a multilayered media network first envisioned so many years ago.

wtf wtf

i have changed house and wth my atheros doesn’t want connect to my network. because the signal is too low….for it…. for the linksys no….

i have madwifi compiled with my hand and if i am near or in the same floor of the router it works fine but …..
\
if i go down in my 2° house wth it just doesn’t work.

i have a linksys wusb54gc with rt73 chip and with 2 big walls ,among router and my cp, plus 30 mt of distance i can use my network without issue….

so ….this is what is atheros : a Shit

guys buy a linksys wusb 54gc with rt73 chip with 19 euro and you’ll not have a problem just plug and go.

This post is dedicated for all MSI Wind U100 series users. Below is the complete list of driver you have to install to keep your netbook driver up to date. I use the driver on Windows XP and all the drivers below worked fine for me.

You can check the latest driver from MSI Wind U100 driver download page here. But there are some drivers that is not available from the site, so you may want to look for them HERE.

Graphic Adapter: Intel GMA 945 Express, can be downloaded from MSI website.

That’s all the drivers required for your Wind U100. Since the latest driver based on the time i write this post, there may be some changes or updates later, so you should check the download sites for the latest version available.

La utilización del wifi es fundamental hoy en día, tuve problemas con este en una notebook MSI VR201 y en una netbook Acer Aspire One 150, estas usan tarjeta wifi Atheros, estuve buscando en blogs y en otras páginas y la principal sugerencia era la instalación de los drivers madwifi, pero después de intentarlo varias veces no tuve resultado alguno, al final encontré una solución mucho más fácil, aquí se las dejo para todo aquel que la necesite:

Primero, si usamos 8.10 vamos a Sistema > Administración > Controladores de Hardware, ahora desactivamos el driver que trae por defecto instalado y luego reiniciamos.

Abrimos la terminal y ponemos:

sudo aptitude install linux-backports-modules-intrepid-generic

Cuando terminemos con la instalación reiniciamos y cuando iniciemos el sistema estará funcionando el driver de nuestra tarjeta wifi. En caso de que no funcione, vamos a Controladores de Hardware y activamos el nuevo driver.

Para los que usen 9.04 hacemos los mismos pasos, pero en la terminal ponemos:

sudo aptitude install linux-backports-modules-jaunty-generic

Ojalá que les sirva de algo.

Siang ini, seperti biasa saya nyalakan notebook acer aspire 5050, masuk ke ubuntu 9.04 untuk melakukan rutinitas browsing internet. Baru beberapa menit muncul update notifier, tersedia update untuk beberapa paket. Tanpa pikir panjang langsung saya klik tombol install updates, setelah beberapa menit berlalu update selesei dan muncul pesan system perlu di restart. Menuruti perintah akhirnya saya restart notebook, tapi upss… wireless atheros koq gak aktif ya?! Saya cek di System > Administration > Hardware Drivers, Alternate Atheros “madwifi” driver dalm kondisi aktif.

Ternyata setelah dirunut masalahnya berasal dari kernel yang ikut terupdate. Akhirnya saya putuskan untuk instal ulang driver atherosnya, setelah googling akhirnya ditemukan langkah-langkahnya.

Langkah pertama adalah instal build-essential

$ sudo apt-get install build-essential

Download driver madwifi dari sini dengan perintah:

$ wget http://snapshots.madwifi-project.org/madwifi-hal-0.10.5.6-current.tar.gz

Disable Atheros Hardware Access Layer (HAL) and Support untuk Atheros 802.11 wireless lan cards melalui menu System > Administration > Hardware Drivers, kemudian reboot (jika diperlukan). Edit berkas linux-restricted-modules-common untuk memastikan modul ath_hal tidak lagi dimuat

$ sudo gedit /etc/default/linux-restricted-modules-common

Tambahkan ath_hal pada Disabled_Modules.

DISABLED_MODULES=”ath_hal”

Untar file madwifi-hal-0.10.5.6-current.tar.gz yang telah selesai di download, gunakan perintah:

$ tar xzvf madwifi-hal-0.10.5.6-current.tar.gz

Masuk ke direktori dimana madwifi Anda letakkan, gunakan perintah:

$ cd madwifi-hal-0.10.5.6-r4068-20090705

catatan : madwifi-hal-0.10.5.6-r4068-20090705 adalah nama direktor/folder hasil untar file madwifi-hal-0.10.5.6-current.tar.gz
Kemudian Jalankan script madwifi-unload dan find-madwifi-modules.sh, gunakan perintah:

$ sudo ./madwifi-unload
$ sudo ./find-madwifi-modules.sh $(uname -r)

Keluar dari direktori madwifi-hal-0.10.5.6-r4068-20090705, gunakan perintah:

$ cd ..

Jalankan perintah berikut untuk memastikan driver terdahulu bersih.

$ make clean

Masuk kembali ke direktori madwifi-hal-0.10.5.6-r4068-20090705, Jalankan perintah-perintah berikut:

$ make
$ sudo make install
$ sudo modprobe ath_pci

Sampai tahap ini driver atheros sudah terinstal.
