What is your CPU load when trying to load web pages? Umm, it's the encryption for WEP done in hardware by the wireless card? Or does this vary from card to card? -- Josh Huber

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.

Wireless question about WEP

by Andy Stewart

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

One right answer is to add "-dpi 100" to the tail end of the line in /etc/X11/xdm/Xservers: :0 local /usr/X11R6/bin/X :0 vt07 -dpi 100 Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Re: [Wlug] Question about WLUG BBQ

by Wesley Allen

I installed freeswan, but didn't configure it correctly and all of the sudden I didn't have access to my lan (remember that e-mail I sent last week? that was the problem). When I have the time I'll sit down and read all about that and ipsec; but I can't right now. WEP is just this annoying buzz that I should be able to make work, and yet can't. It's annoying. I know it's cracked, but it's still annoying. Wes On Fri, 2002-07-19 at 10:28, Josh Huber wrote: > Wesley Allen <wallen(a)charter.net> writes: > > > Did you guys set up WEP?

A cow-orker of mine once said, "It's a lot of work, but I'll take a large chuck." And I continued the thread for a bit, discussing what chuck of work everyone would be doing and no one noticed. Incidentally, when I got email from Fr. Scanlon, I was often referred to as Chuch. Funny that finger memory. :) As long as it's not an upchuck joke... -Chunk
