DHCP using ral
I'm trying to set up a connection between an FBSD box and a wireless access point. The background is that there's no security on this network; as the person who set it up says, You just start your computer and it works! I have an XP box with a wireless NIC working, but I don't want to use the XP box as the gateway for my personal lan to an insecure network. On the XP box, if I point a browser to 192.168.1.1, I'm told that the router is WRT54GX2, which I take to be a popular Linksys router. I don't have physical access to the router and I don't have the password for the router. I've got a wireless Linksys NIC that uses the ral driver facing the wireless router. The NIC facing my lan uses the em driver and is working fine. uname -a says FreeBSD 7.2-RELEASE #0. In rc.conf I have ifconfig_ral0=DHCP After booting, if I ping 192.168.1.1, I get no route to host and I have no lease file in /var/db. ifconfig ral0 tells me that I have no inet address associated with ral0, status is no carrier, and the ssid is an empty string. dhclient ral0 sends a series of DHCPDISCOVER messages, but I get no DHCPOFFER messages, and I get an empty lease file. If I run ifconfig ral0 again, inet is 0.0.0.0, status is associated, and ssid is the proper ssid for the wireless router. ifconfig ral0 list scan gives the proper information for the router. At some point I did get a proper lease. I don't know when or how. I've never had a usable connection to the router from the FBSD box, and I've never had access to the nameservers listed in the lease. If I rename the old lease file to dhcp.leases.ral0, and then run dhclient ral0, I send 3 DHCPREQUEST messages, 2 DHCPDISCOVER messages, 2 DHCPREQUEST messages, and 6 DHCPDISCOVER messages. dhclient tells me that no DHCPOFFERs were received, and it binds to the address in lease file, 192.168.1.104. However, ifconfig ral0 shows no inet address. I still can't ping the router. ifconfig ral0 inet 192.168.1.104 netmask 255.255.255.0 assigns the specified values. Ping no longer tells me that there's no route to the host, but I'm getting about 95% packet loss. netstat -r now shows that link1 (ral0) is the gateway to 192.168.1.0. I still don't have a usable connection. resolv.conf says nameserver 192.168.0.1, which is the nameserver for my personal lan. I can't nslookup URLs outside of my lan. If I manually add the nameservers in the dhcp lease, I can nslookup www.google.com. But ping has 100% packet loss. /etc/hosts associates 127.0.0.1 with localhost.krig.net, and 192.168.0.6 with stamfordbru.krig.net, which is correct for my lan. I'm stumped. :) I don't know if this is related; the XP box is telling me that the router has no connection to the internet, but it obviously does have a connection because the XP box can load web pages and I can use my gmail account.

I still don't have a usable connection. Not especially helpful but I thought I'd throw this out there, Linksys routers by default define their DHCP range as 192.168.1.100 - 192.168.1.149, so pick an address outside that space if you're trying to assign statically. You can often get away with setting the IP of the router (default of 192.168.1.1 for Linksys) as your DNS, as many Linksys routers have a built in DNS proxy. Are you sure you're getting a strong enough signal from the AP? Have you had success with this WiFi card accessing other APs? Do you have access to a different WiFi card you could try? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Good point. I tried that, but 192.168.1.104 and 192.168.1.150 work the same. No difference that I can tell You can often get away with setting the IP of the router (default of 192.168.1.1 for Linksys) as your DNS, as many Linksys routers have a built in DNS proxy. Ah. That doesn't solve the problem, but it works and it's useful. Are you sure you're getting a strong enough signal from the AP? I think I am. The XP box is reporting a strong signal, and it's on the self below the FBSD box. Of course, the XP box is also reporting no Internet connection, and I'm using it to reply to you, so who knows. The XP box with a Belkin NIC works pretty well. The boxes are very close, so I'm guessing that signal strength is not an issue. Have you had success with this WiFi card accessing other APs? I have no other APs I can try it with. The only other AP within range is none of my business. Do you have access to a different WiFi card you could try? No. This Linksys card was the only PCI card at the local MicroCenter that was supported by FBSD 7.2. :) Thanks for your interest in my problem. :) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Thanks for any help. I happen to have a Linksys router (not the same model though) and a Linksys pci card that uses the ral driver. Never had any problems, though I am not using DHCP. Here are a few manual steps to try: First off, try setting the ssid on the command line: ifconfig ral ssid Myssid Execute ifconfig by itself, and see if you get an associated message. (you may have to wait a minute before you do) If you don't, chances are the following will do nothing dhclient ral0 if this does not succeed, set an IP address manually: ifconfig ral0 inet 192.168.1.50 netmask 255.255.255.0 Before attempting to test the internet connection, add the router as nameserver in /etc/resolv.conf and don't forget to add the router's address as the default gateway: route add default 192.168.1.X From my experience, the important part is to get the associated message after the initial ifconfig. Not much hope otherwise. As an afterthought, is the XP machine on while you are trying to connect? If they are too close they maybe interfering. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
