Hi, with the latest ndis commits 802.11 support should be better, nevertheless I get a panic when setting an IP address with ifconfig. if_ndis loads fine: ndis0: <Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter> mem 0xc0200000-0xc0200fff irq 11 at device 2.0 on pci2 ndis0: failed to enable port mapping! ndis0: failed to enable port mapping! can't re-use a leaf (ESS_ID)! no match for NdisUnchainBufferAtBack no match for NdisGetFirstBufferFromPacketSafe status: 400100fe status complete status: 4001000c status complete ndis0: 802.11 address: 00:04:23:7e:d9:98 ndis0: 11b rates: 11Mbps 2Mbps 1Mbps NDIS dummy called... last message repeated 50 times reset done...
