Karty wifi polecane do Backtrack.pl oraz Kali Linux[edytuj]

Generalnie 90% kart w BT działa out-of-box, na te które tego nie robią, nie ma sposobu. TO NIE WINDOWS! TU NIE DA SIĘ ZAINSTALOWAĆ STEROWNIKA Z STRONY I JUŻ! Musisz czekać aż sterownik zostanie napisany i dodany do kernela.

Najważniejszą częścią karty jest układ radiowy. Producent czy model nie informuje nas o tym jaki układ jest w jego karcie. Mamy tysiące prodcuentów (np. Linksys, Netgear, D-Link, TP-Link, ASUS, Techniclan, ALFA, Tonze, Ubiquity, Belkin, Edimax) ale tylko kilku producentów układów radiowych: Atheros, RaLink, Realtek, ZyDAS, Prism, Texas Instruments, Proxim, Intersil, Intel, Broadcom.

Jak sprawdzić układ karty?[edytuj]

Wpisując Producenta, model a czasem nawet rewizję na stronie: Wikidevi

Jaką kartę kupić?[edytuj]

Polecam szukać kart z dobrym wsparcie z strony linux-a, czyli takie z układami firm: Atheros, Realtek or Ralink. Układy innych firm nie są najlepszym rozwiązaniem do testowania zabezpieczeń.

Najlepsze ukłądy radiowe:[edytuj]

  • Atheros AR9271 - dobre wsparcie linux-a, wysoki injection rate, tylko najnowszy kernel pozwala na zmianę MAC (na Backtrack.pl oraz Kali Linux), szybkość linku do 150Mbit (realnie do 64Mbit), ekstremalnie wysoka czułość!
  • Realtek RTL8187L (RTL8187 = RTL8187L) - dobre wsparcie linux-a, wysoki injection rate, działa zmiana MAC, niska prędkość połączeń max. 54Mbit (realnie 20Mbit)
  • Atheros AR9285 - praktycznie kopia AR9271 w innej obudowie,
  • RaLink RT2571 - dobre wsparcie linux-a, wysoki injection rate, łatwo zmienia MAC, 54Mbit, __BARDZO niska czułość!_-
  • RaLink any RT27XX RT28XX RT30XX - dobre wsparcie linuxa, wysoki injection rate, łatwo zmienia MAC, wysoka szybkość linków (niektóre modele ja RT2770 wspierają 300Mbit), wysoka czułość.

DOBRE układy radiowe:[edytuj]

  • każdy Atheros chip - praktycznie każdy układ tej firmy to dobre rozwiązanie ,
  • każdy RaLink chip - firma bardzo pracuje nad sterownikami dla linux-a i praktycznie każdy układ działa (istnieje kilka implementacji w kartach które są "do kitu!"),
  • Prism (PrismGT Prism54) - działają, nadają się jako Soft-AP lub na codzień,
  • Atmel - bardzo dobry układ, ale nie znam modelu który wspiera G/54Mbit nie mówiąc o N,
  • Hermes/Orinoco/Proxim - kilka starych kart posiada ten układ (Hermes) jest to układ który w 11Mbit/B jest najlepszym układem, używany do dziś w otwartych sieciach. Niestety wsparcie dla niego zostało usunięte z nowych kerneli linux-a.
  • układy niskiej jakości lub niewspierane przez linux-a:
  • inne układy Realtek-a niż RTL8187L (e.g. RTL8188 RTL8192) - niektóre działają pod linux-em ale oprogramowanie ma wiele błędów. Czasem działa monitor mode, czasem,

any Intel chipset - some models work well under Windows, but Linux support is lacking, Broadcom - some models work, some even have monitor mode working, but generally support is poor, any others not listed.

Bardzo dobre karty:[edytuj]

  • ALFA AWUS036NHA (AR9271) - wysoka moc 500mW, bardzo czuła, 150Mbit
  • Techniclan WUSB-54G (RTL8187L) - tania, czuła, tylko 54Mbit
  • TP-Link WN422G WN722N (AR9271) - tania ~40zł lub ~30zł używana, bardzo czuła, szybka 150Mbit
  • Inventel UR54g(R01) v1.1 lub GlobespanVirata Cohiba 3887 rev0 - bardzo czuła, niska moc około 60mW, tylko 54Mbit, obsługa WPA/TKIP WPA2/AES

Odpowiedź jest prosta, NIE! To nie jest dobry pomysł ponieważ: Wzmacniacz wzmacnia też szum, a to bardzo źle wpływa na jakość połączenia. Przy dużym wzmocnieniu występują niepożądane efekty które uniemożliwiają połączenie tobie oraz każdemu w okolicy. Dużo lepsze wyjście to zakup anteny o wysokim zysku.

Producent twierdzi że karta ma 20dBm (100mW) ale faktycznie ma tylko 18dBm, dlaczego?[edytuj]

Większość kart ma 100mW w połączeniu z anteną 2dBi. W trybie 802.11a and 802.11g, moc nadawania wynosi 30mW z powodu modulacji (używanie OFDM jest troszkę trudniejze niż CCK)

Czy nadają z największą mocą będę miał najlepszy zasięg?[edytuj]

Nie, w większości przypadków. W warunkach domowych, nie zawsze najwyższa moc jest najlepsza. W większości sytuacji, 30mw wystarczy. Czasem, gdy jesteś daleko do AP, większa moc może pomóc ale tylko wtedy gdy obie strony nadają z taką samą.

Czy będę odbierał lepszy sygnał gdy ustawię większą moc nadawania?[edytuj]

Nie, moc nadawania nie ma nic do odbierania. Sprawdź czułość karty, aby sprawdzić jaki sygnał odbiera lub możesz kupić antenę o większym zysku.
