| So my wife fires up her powerbook last night and tries to get to the net on my home wireless network. This has worked before, she says she hasn't changed anything, and I know I haven't changed anything on the network. So she get's nothing and asks me to take a look. What I discovered: She can see my AP, and is attaching to it. She's not getting a dhcp address. I try to renew the lease, she still get's nothing. I set it manually, and she can't ping the gateway or my computer. My laptop, set up on the wireless network works perfectly. If I give her a static address and try to ping her, I get a response. If I use her powerbook to try to ping my PC, I get nothing. I disabled all filtering, turned off her firewall, etc. etc. etc. Pinging loopback on her computer gets a response. Attaching her to the wired network and everything behaves exactly as it should. I ran some diagnostic tool (I don't remember what it's called, but it has really pretty graphics) and the only hardware error it found had to do with her video (which appears fine to me). If I didn't get a ICMP echo reply from her box when I ping from mine, I would say her transmitter is borked on her wireless card. As I do get a response, I don't think that's the case. It was getting late so I didn't nmap it, hook up an ethereal box on a spanned switch port, or any of the other stuff I would normally do, but I was hoping someone here had seen this before and can make me look like a hero when I come home tonight without having to spend a couple hours troubleshooting. :) |
