 Posted: Tue Aug 10, 2004 7:37 am Post subject: Wireless.. No route to the Internet |
 |
|
I've had this problem for 3 weeks straight and all of the time, I thought its got to do with the wireless-script. Last week, I changed from orinoco to hostap which provided scanning and monitoring and upgraded the wireless-script. As a result, I now can get an IP address through DHCP at the college canteen. Even orinoco drivers when tested again managed to obtain an IP address. I noticed there are around 3 or 4 wireless APs with the same name "WLAN".
After obtaining the address, whenever I try ping www.whatever-u-want.com, nothing came up but the DNS resolved correctly. While other Windows users are enjoying, I'm left wondering why. Please help. |

try the following code :
and verify that the default route, or the route for your wireless interface is ok (compare with ifconfig)
You can check in /etc/conf.d/net and see if the line gateway="whatever" is commented ( a leading #) |

Hmmm route doesnt show your gw as .254, have you tried changing this in /etc/conf.d/net ? Maybe just changing it from the host to the ip may help. Odd tho.....
Either that or maybe adding your gw's hostname -> ip to your hosts file?
Not sure that will help, but it may

I'm going to try the hosts file but I'm not sure what to add.
192.168.1.254 proxy proxy.sunway.edu
Is it correct? Wouldn't it be overwritten everytime net.* scripts run dhcpcd?
Thanks gnuageux |

Another Q. If I insert that entry into hosts file. It will just resolve
proxy.sunway.edu -> 192.168.1.254
but then I can't ping 192.168.1.254. Just a guess but I'm thinking that it either means i can't get 192.168.1.254 or some firewall behind it denying the packets i sent. |

the weird thing is that your resolv adress on your first post.
What are the nameserver you use ?
> more /etc/resolv.conf
and
> nslookup

Didn't bring my laptop today, right now I'm on the a public comp in the library which is on a separate network and I'm just playing here and there to see the network. I'm dont know many windows tools.
So route PRINT gives me this.
| Code: |
C:\WINDOWS>route PRINT
Active Routes:
Network Address Netmask Gateway Address Interface Metric
0.0.0.0 0.0.0.0 172.16.32.2 172.16.32.132 1
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
172.16.32.0 255.255.248.0 172.16.32.132 172.16.32.132 1
172.16.32.132 255.255.255.255 127.0.0.1 127.0.0.1 1
172.16.255.255 255.255.255.255 172.16.32.132 172.16.32.132 1
224.0.0.0 224.0.0.0 172.16.32.132 172.16.32.132 1
255.255.255.255 255.255.255.255 172.16.32.132 172.16.32.132 1
|
The gateway is 172.16.32.2
Then I tried pinging yahoo.com.
| Code: |
Pinging www.yahoo.akadns.net [66.94.230.39] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
|
But this computer can connect to any other website like normal..
EDIT: I mean that I can connect to any website including yahoo.. |

Which version of windows is it? I think that you can ipconfig /displaydns to see what name servers your using from dos.

Perhaps the school blocks ICMP echo-requests?

I don't know of a /displaydns switch in Windows 2000 or Windows XP, but "ipconfig /all" should work. |

That link does not work for me.
"Were sorry, but there is no Microsoft.com Web page matching your entry. It is possible that you typed the address incorrectly, or that the page no longer exists. You may wish to try another entry or to use the links below, which we hope will help provide you with the information you need."
This link does show the /displaydns switch, but the information I get from running on Windows XP Professional

| I lost my gentoo installation (damn cfdisk) and re-install winXP. I'll re-install gentoo later. It's odd that here I am in Windows and I can obtain an IP address from DHCP but I have the same problem of not being able to connect to the internet. |
