I have a Windows Vista laptop here with an Atheros AR5007EG wireless card. When attempting to connect it with an AVM Fritzbox 7330 the following happens:
- Laptop successfully negotiates DHCP and receives correct IP-Address, Router-Address and Subnet
- Laptop broadcasts ARP-request for Routers IP
- Router receives request
- Router sends answer to MAC-Address of Laptop
- Laptop never receives the answer
The laptop continues to send requests, the router receives them and answers but they never arrive. This goes on until I disconnect the laptop.
This problem doesn't occur on any other of my machines, connecting the laptop via ethernet cable does work.
So IMHO it can't be:
- the operating system
- the router
Any ideas where to look next would be appreciated.
