Ubuntu

cannot enter router webpage

Asked by Caterpillar

I have a Linksys router (model BEFSR41). And I used to enter the http://192.168.1.1 to access the router webpage.
After the upgrade to Kubuntu 8.10 (from the 8.04) I cannot enter the routerwebpage. I use Opera, but also trying with other web browsers this happens again :(

Trying to ping the router I have the following messages from the Konsole

caterpillar@Magic-3: ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
From 192.168.1.100 icmp_seq=1 Destination Host Unreachable
From 192.168.1.100 icmp_seq=2 Destination Host Unreachable
From 192.168.1.100 icmp_seq=3 Destination Host Unreachable
From 192.168.1.100 icmp_seq=5 Destination Host Unreachable
From 192.168.1.100 icmp_seq=6 Destination Host Unreachable
From 192.168.1.100 icmp_seq=7 Destination Host Unreachable

I don't know why Linux tells me that the destination host is unreachable, I cannot understand this because my internet is working well.
To configure router ports I have to use my laptop instead using the desktop computer. The laptop have Kubuntu 8.10 too but is working well and can access the router's webpage

You need to change your Ubuntu network ip it must be something like

ip: 192.168.1.2
netmask: 255.255.255.0

Or, i think better, put it as DHCP

Hope this helps

Why if I tell the computer to ping 192.168.1.1 Kubuntu pings the 192.168.1.100 ? Look at first post

No it ping from your nic that have ip 192.168.1.100 so you can't reach the router. Please change your ip

Thank you

To get better nic settings info open a terminal and type:

ifconfig -a

I have 2 ethernet port in my pc. I'm using eth0 at the moment, and eth1 is unplugged. The computer still write the ip (192.168.1.100) that I've set months ago (static ip address) with the Kubuntu 8.04. Kubuntu 8.10 has problems on static ip addresses so I had to change port (to eth0) and configure it with DHCP.

Here the ifconfig -a
