Wireless question about WEP
Hi all, I got 64 bit encryption between my laptop and my access point working but there is a problem. The password is OK, and I can ping from my laptop to my network with 64-bit WEP enabled. Others on my network can ping the laptop without any problems. The trouble arises when I try to use the link for something useful, like surfing the web. Web pages come over very slowly if they complete at all. On a wired system, the page comes over quickly, so its not the other end of the Internet causing the problem. If I turn off WEP, everything is great. Also, I seem totally unable to make 128 or 256 bit encryption work at all (not even a successful ping) despite the fact that both sides agree on the password. What should I check? I am using the orinoco_cs driver in the 2.4.18 kernel. My hardware is the Linksys WPC11 (version 3.0) and the Linksys WAP11 version 2.2 Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Encryption slows things down. I guess something isn't well implemented (WAP or 802.11b card). It shouldn't be THAT bad, though.

For 128-bit WEP, make sure there are exactly 13 octets (26 hex digits). I know this comes out to 104 bits, but thats actually correct. Don't ask me how that makes it 128-bit...must be a salt in there or something. -- Charles R.

Umm, it's the encryption for WEP done in hardware by the wireless card? Or does this vary from card to card? -- Josh Huber

I think it is possible for the driver to handle it in software if the hardware doesn't have 128-bit capability. I could be wrong... -- Charles R.
