 |
|
Hi,
I recently moved into a new house and because of this I had to pick up a new wireless router (a Linksys WRT-100). My desktop is having trouble connecting to it. I have 3 other devices that have no such issues (more information on those later).
I can get an IP and what not from the router through DHCP. I can also manually configure it with ifconfig and iwconfig. The problem I'm having is that I am not able to connect to anything. I am able to ping my local host and that is about it.
I am using madwifi-ng-0.9.4.
This is what I get when I try to ping anything outside of my local network :
When I try to ping my router I get this :
| Code: | localhost bill # ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1197 ttl=64 time=1.28 ms
--- 192.168.1.1 ping statistics ---
1374 packets transmitted, 1 received, 99% packet loss, time 1372999ms
rtt min/avg/max/mdev = 1.282/1.282/1.282/0.000 ms |
When I try to bring up my routing table I get :
| Code: |
localhost bill # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
|
It becomes unresponsive and I have to ctrl-c to get back to my command-line.
It feels to me that my computer is having some sort of issue with the routing table.
I have a laptop running Gentoo (it is a 64-bit using madwifi-ng-0.9.33), a Windows XP desktop and an iPod Touch that all have no problem connecting to and using the network. Because of this I highly doubt there is an issue with the network itself.
Here some additional information that might be useful.

If anyone has any ideas it would really help.

It sounds like you are having a DNS problem. Try "route -n" instead, and see if it works without hanging.
Take a look at /etc/resolv.conf to see if you have valid nameserver(s) defined.
... and if your /etc/conf.d/net has something like this, then please get rid of it.

Thanks for your help. Unfortunately, it doesn't look like any of those suggestions seem to remedy the problem. Here is what my output and configs look like.
route -n gives me this
| Code: |
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 ath0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 ath0 |
my resolv.conf is
| Code: |
# Generated by dhcpcd for interface ath0
search hosts.bc1.bresnan.net
nameserver 69.145.248.50
nameserver 69.145.232.4
nameserver 69.145.248.4
nameserver 192.168.1.1
|
and finally my /etc/conf.d/net looks like
| Code: | # This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
config_eth0=( "dhcp" )
dhcp_eth0="nontp nonis"
preup() {
if [ "${IFACE}" = "ath0" ]; then
/sbin/wlanconfig ath0 create wlandev wifi0 wlanmode sta
return $?
fi
}
postdown() {
if [ "${IFACE}" = "ath0" ]; then
/sbin/wlanconfig ath0 destroy
return $?
fi
}

| I got ambitious and decided to try to connect to my network via Ethernet. Therefore it has to be a problem with my card or settings. Anyone have similar problems? |
