SuSE 9.2 Pro, Centrino Card, Wireless works in LAN, not on WAN
Hi, I've searched already, though I didn't see anything posted about my issue.
I have a Toshiba M30 laptop, which has the Intel 2100 series wireless card. (It's a Centrino) I have SuSE 9.2 Professional with all the wireless packages installed, and I updated them using my ethernet connections.
Here is my situation. I have a D-Link DI-624+ Router which uses WPA-PSK. I am able to ping the router (and my SMC router which is connected to the D-Link via ethernet). Now, my D-Link has a DHCP server enabled, and my SuSE gets the address. It also has DNS with DNS forwarding. Here is where it gets interesting.
Using Ethereal, I decided to capture my packets and see where my problem is. If I was to type in "ping (www)google.ca" (Had to use seperated www cuz I'm not allowed to post URLs yet.) I would see the router send back the proper IP address for (www).google.ca. However, my prompt would say "connect: Network is Unreachable"
So, I type in the IP address that was sent back through DNS, and I would get the same message. I typed in the DNS server IP address of my ISP, and I would get the same message, "connect: Network is Unreachable"
Here is the REALLY interesting part. When I type in "ping (www).google.ca" I would get some traffic logged in Ethereal. (DNS working, and my router forwarding the info to my computer) If I typed in strictly an IP address, I would get NOTHING in ethereal. It won't even ATTEMPT to contact even my Default Gateway! (Configured as my D-Link wireless routers LAN IP)
Now, I've searched google and this forum, and I didn't see anything. Maybe I'm blind, (or this beer is kicking in more than I thought).
Also, I thought that maybe it was the firewall. I've flushed the entire iptables list, still nothing. Re-activated the firewall, and allowed DNS access. Same thing.
Now, something else. (Sorry about it being all over, it's just that my thoughts are a little scattered right now.) The only way I can get DNS to work, is if I put in the "Host name and name server configuration" the following:
Name Server 1: 192.168.2.2 (LAN IP of my wireless router)
Name Search 1: home
Could the Name Search be an issue? It's supposed to be for the domain name, I don't really have one. The name for my home network is "home". I also have the "Update name servers and search list via DHCP" option checked.
I've taken the "Name Search 1" field out, and if I click "Finish" and go back in, it's there again.
I'm a little confused, hopefully I didn't confuse all of you. To give you an idea of my network background, I'm currently taking Network Engineering, I've taken the first 2 of 4 semesters of CCNA.
I have just upgraded ethereal to ver 0.10.8 on my winxppro for tablet pcs on which I run suse9,2pro under VMware4.5.2. I had a problem that I could no longer access www.sec.gov (I couldn't even ping it and traceroute timed out at hop 18) and I got help from an aquaintance who allowed me to use his server as a proxy (in the US). Anyhow, to cut a long story short, my acer tablet was connected to a wireless (Netgear WG602) using my centrino LAN 2100 38 Mini PCI Adapter - after much searching on the ethereal website - I found that ethereal cannot presently pick up packets when using the centrino. I solved my problem by plugging in my Netgear Wireless PC card WG511, which immediately appeared on my Capture>Interfaces list, cancelling (disabling) the centrino allowed me to see all network (home-based 3 box LAN) and I was able to see the traffic going through the proxy (on a specific port, which I had opened in my firewall(s).
Hope this helps, as it appears that you have been trying to use ethereal to track the centrino traffic, which is currently a physical impossibility. Perhaps you can hardwire (Cat5 cable) your box to the net, just for purposes of using ethereal.
Good find on that Centrino issue with Ethereal! That would explain some things! However, I tried the same thing on my other laptop, a Toshiba A70 which has a different wireless card (Atheros chipset). The same thing. It wouldn't even ATTEMPT to leave the network.
So, I looked at this thread:
(http://www.)linuxquestions.org/questions/showthread.php?s=&threadid=13530 (Sorry about the brackets, I'm still not allowed to post URLs until after I've made 5 posts or something like that...)
Well, I tried what was recommended there. I removed the ethernet from the network device list, and BAM! It works on BOTH my laptops! I kinda remember having an issue with that now. Something with the routing table. I can't remember exactly what it was, but I think whenever I made a change to the default gateway on my ethernet for example, it would put it in the wireless automatically, and vise-versa.
Plus, when I was using Ethereal on my A70 laptop with a non-Centrino card, I would still pick up all the DNS traffic, though my routing table never fully updated. Even after getting a DNS reply with an IP address for google.ca, my routing table would just have the network address for my routers IP address. (Router IP was 192.168.2.2, and the network address showing up was 192.168.2.0, which made sense.) It would simply not put anything else in there.
Anyways, big thanks to all who helped, including those in the thread I quoted way up there^^^!
Hopefully this little glitch with the ethernet and wireless combo can be fixed. It would make my life a little easier. (I use wireless at home, but ethernet at school.)
