Testing Cisco WLAN card - do these statistics matter?

[kranky]

I'm testing a Cisco wireless LAN PC card at work. It has a utility that shows low-level statistics and I was watching them during a huge file transfer. I'm having an issue where Microsoft Backup aborts while backing up even though moving big files through Windows Explorer works fine. Backup works fine if I'm using the wired LAN.

Anyway, while receiving a 250MB file which took 4 minutes, the utility shows there were about 38,000 MAC CRC errors on the receive side (showed 500,000 total packets received) . On the transmit side, there were 40,408 packets listed under "Packets Retry Long" and the exact same number of packets shown under "Packets No Ack Received".

Does any of that indicate something is wrong somewhere? Or is it no big deal?

What configuration are you running? Do you have WEP turned on? Are you using WPA? What type of AP are you using?

I had to get back in to work before I could get some answers. I'm not a networking expert so hopefully this is what you wanted to lmpw.

This is on a XP Pro machine. WEP is enabled. I have a VPN connection (the security guy made this mandatory for wireless users) also. The network connection is set to enable 802.1x authentication using EAP (with a certificate).

I don't know for sure what type of AP it is (it's up in the ceiling) but it's probably something from Cisco.
