does WEP affect only throughput or range too?

Adding WEP does not change the speed. It can impact throughput though, because encryption/decryption takes time and processing power.

If you're referring to speed as "it now takes longer to download/upload a XXXX byte file" - that would actually be a throughput issue. An eleven meg connection is an eleven meg connection. When data is moving, it's moving at eleven meg. The time it takes to get the packet ready for transmission or unbundling it after it's received is what's affected by WEP.

FWIW

Since WEP isn't at the application layer does it affect how much data can fit in each packet? With things like SSL and SSH you lose some space to protocol/encryption overhead, what about with WEP?
 
I've never actually researched it, but it seems that WEP could indeed affect the throughput by some amount. It seems logical that there is some overhead there, I wonder if anyone has an actual reference?
 
I believe (I'm gonna look it up when I get some time...) that with the error correction and redundant bits, and all the other stuff associated with wireless that the payload stays the same, but the overhead is very large ... i.e., a chunk of data that would make one exactly-max-sized Ethernet frame on a cable is much larger between the wireless client and the receiving system (ad-hoc or AP). The additional stuff is strictly there for managing the wireless connection (SSID, for example).

It might (IIRC) even be a mutation of PPP (you know how it goes... you pass the test and then forget everthing).

As long as it works satisfactorily, and I can't change it, it never really mattered to me....

IT wouldn't affect range. The power of the radio signal wouldn't change, and encryption has nothing to do with error correction. If the signal quality is good enough to "get there" without WEP, it'll "get there" with WEP enabled.

Good Luck
