Is 802.11i supposed to be faster than G?
Is AES better than WEP? |

Ratified in June, that means Linksys should post a firmware upgrade for my WRT54G around 2006.
I've given up on them ever implementing WPA let alone this in my 802.11b devices.

Re: faster?
802.11i has nothing to do with speeds; it only deals with security. And yes, it is much better than WEP. |

1 edit | firmware upgradable?
My understanding has always been than existing b/g hardware would not be firmware upgradable to 802.11i/WPA2 due to various cpu and other hardware alterations within the circuits? As mentioned in the Article itself.

From my understanding, AES was/is widely used for Government security of encryption. Yes AES will be better than WEP due to the fact it is more powerful. Unfortunatley, most hardware out there will not be able to handle it, and you will end up spending more money, at leaste for a home user to take advantage of it
Maybe on a business stand point, AES will benefit, but as for a home user, WEP will do the trick.

Re: firmware upgradable?
If the card or access point has a dedicated AES chip (I believe Zyxel and some Netgear's has this) all it would take is a software/firmware upgrade to use the cchip for AES processing. |

| WPA2 is a certified name for IEEE 802.11i
WPA is a specification of Wi-Fi consortium based on draft IEEE 802.11i standard. WPA2 will be based on the final 802.11i standard.
Wi-Fi is a private industry group while IEEE is a standards body. Wi-Fi does not certify IEEE standards. They can only adopt them like they did for WPA and WPA2. They can then certify vendor products to WPA2. But that does not mean they are a body to certify IEEE 802.11 standards. |

WPA support should be in the Radio unless the vendor is implementing host mode AP functions (processing and encrypt/decrypt raw frames in CPU environment). Most AP implement AP functions in the card firmware itself (firmware AP). They download the AP firmware to the card and card (wireless module) does the enryption and decryption. For this reason if the card firmware could be upgraded to handle AES than WPA2 upgrade could be done. |

I think Linksys has implemened a WPA driver for WPC11 v2.5 and 3.0.
ZyXEL has working WPA drivers for most of their B series PCMCIA client cards. B-100, B-120, B-122 (it took a long time for them though)
Unfortunately, most vendors did not do enough effort to provide such capability.
I think once 802.11i is ratified and WPA2 is adopted it would be a good time to upgrade old 802.11b cards. |

I believe soft radio based 802.11b/g cards should be able to support the new standard. Atheros and Broadcom 802.11b/g and 802.11a/b/g cards come to mind. |

Re: faster?
AES is an encryption method, WEP is a communications protocol. They aren't directly comparable. But 802.11i will be much more secure than WEP.

We currently use AES encryption on our 5.8 radios for HIPPA compliancy.

Well, some WLAN chipset vendors implemented AES as an proprietary extension of WPA but it is not part of WPA specification. For 802.11i/WPA2 there are more changes than simply AES. In other words,
WPA + AES <> WPA2
(However vendors that implemented AES with WPA is probably pretty close to WPA/802.11i) |

Re: faster?
It'd be more "apples and apples" to compare AES with RC4, the encryption method used by WEP.
AES succeeds 3DES as the gov'ment's encryption method of choice. A proper implementation of AES is a helluva lot more computationally efficient than 3DES. This means your PDA can now not only support WPA 2.0 but also IPSec. |

What is the difference between WPA's TKIP and AES? Or are they two different things, or the same thing?

Thanks.

AES? What's that? It wasn't mentioned until the 2nd poster brought It up.
I belive that WPA2 is much better than WEP and AES(Whatever that is), Which is now supported by Windows XP Home & Pro. Go download the update for It If You have not already done so.
And I don't believe AES is supported by XP.
WEP do the trick? WEP is weak and has been broken from what TechTV says.

That's good to hear, WEP is laughably insecure.
