Hi, I'm just beginning to learn about Linux networking, so please bear with me. I have a home WiFi network that has been working fine for ages, which currently supports two Windows-based laptops and a WM5 smartphone. They all connect to the WiFi router (Linksys WRT54G) which in turn connects to the ADSL modem (Huawei MT882). The router is configured with a WEP key, the SSID is not being broadcast, and all MAC addresses must be whitelisted. I try to follow good wireless network security practice. I also have NAT running between the router and the modem.
Everything is working fine for the Windows clients, and now I am trying to add my Linux box to the mix. I am setting up an older HP Pavilion 510a desktop with Ubuntu v8.04LTS, using a Realtek RTL8185 WLAN card. The machine has an onboard RTL8139 LAN adaptor also, which works fine when I plug it in directly to an ethernet port on the wireless router. The WLAN, however, does not seem to be getting a DHCP packet, and keeps on autoconfiguring with a 169.254.x.x address. When I try giving it a static IP address it doesn't connect either.
As you can see from the screenshots below, the WLAN is working fine. I have it installed using the ndiswrapper and Windows drivers. I've been through the Comprehensive ndiswrapper troubleshooting guide but that did not resolve my problem.
I configured the network myself, and it works perfectly for my Windows machines. It is just my lack of experience with Linux which is preventing me from getting the wireless to work under Linux. I can get a HDCP packet in Linux when I am connected to the LAN using the RTL8139 adaptor, but not on the WLAN using the RTL8185 adaptor. Any advice would be appreciated.
