    Under Wireless Security of WRT54GS, WPA gives you options of TKIP, AES, and TKIP+AES; however, I've WUSB54G client adapter that has both TKIP and AES but not TKIP+AES. I don't have it on hand at the moment, hence the question.

    Would TKIP+AES work with my adapter???

    Thanks. :)

    it means it uses TKIP or AES -- for compatibility reasons with older clients.. it doesent use TKIP+AES together AFAIK

    It'd be labeled as "TKIP/AES" in my opinion.

    Thanks for your reply. :)

    According to the user manual it you can select AES or TKIP. It states the AES and TKIP are available under WPA-PSK. Maybe that is the source of the confusion. Does the WEB based security page say AES+TKIP?

    It has...

    * TKIP
    * AES
    * TKIP+AES

    Which version of the firmware are you using?
    I have the WRT54GS and don't have an option for TKIP+AES.

    I am using the Firmware Version: v3.37.6

    Also, I had bought a USB client adapter and had problems.

    If you can take it back,
    My opinon is if you have a PC, get the WMP54GS PCI adapter or for a laptop get the WPC54GS adapater.

    If your adapter is G, you won't get the advantage of the GS routers speed booster.

    Linksys BETA firmware has that option.

    It will use AES as default on all clients capable of running AES.
    It will use TKIP for clients not being capable of running AES.

    I have a quick question: what is the advantage of TKIP over AES, and v.v.?

    Also, which is better over the two? Why?

    Here's a breakdown of the difference.

    TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. The TKIP [security] process begins with a 128-bit 'temporal key,' [which is] shared among clients and access points. TKIP combines the temporal key with the [client machine's] MAC address and then adds a relatively large 16-octet initialization vector to produce the key that will encrypt the data. This procedure ensures that each station uses different key streams to encrypt the data. TKIP uses RC4 to perform the encryption, which is the same as WEP. A major difference from WEP, however, is that TKIP changes temporal keys every 10,000 packets. This provides a dynamic distribution method that significantly enhances the security of the network.

    AES supports key sizes of 128 bits, 192 bits and 256 bits and will serve as a replacement for the Data Encryption Standard (DES), which has a key size of 56 bits. In addition to the increased security that comes with larger key sizes, AES can encrypt data much faster than Triple-DES, a DES enhancement that which essentially encrypts a message or document three times.According to NIST's AES overview: "The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information." It is based on the Rijndael algorithm, named for Belgian researchers Vincent Rijmen and Joan Daemen, who developed it.

    Draw your own conclusions.....
