Hi, thanks again for all your help. Unfortunately not been able to use this laptop for the last couple of days (the only laptop on which the internet works), but now I’m back to trying to resolve my internet connection.
This working laptop is a Mac. I’m pretty sure it is on the network as 192.168.1.3 and my Linux laptop is on as 192.168.1.2 (I know this because of the ‘Attached Devices’ on the router web interface. My laptop is obviously connected because it is displayed as LINUX-PGQI).
When you say you logged into the router, how did you do this - via a web browser and typing in the ipaddress 192.168.1.1?
Yes,I use firefox to access the router at “http://192.168.1.1/start.htm”.
I remember from when I had cable, the cable router gives an ipaddress via dhcp and this is not on the private 192.168.xxx.xxx ranges. The trouble is that this also logs the mac address of the first nic you use to connect to it and won’t let you connect with a different nic.
This meant that I had to do some nic swapping when I put in my smoothwall box and got the local network running.
I would wager that 192.168.1.1 is the ip of another pc on the network and not the router’s ip.
The laptop you are using for your replies - what os is it using?
If windows, open a command line and type ipconfig /all and you should get all the relevant details.
Was this perhaps also the first pc you used to connect to the internet?
This Mac laptop was indeed the first machine that I had connected to the network when it was first installed, but I have had both laptops working on here for 5 months. It was only last week that my Linux connection stopped working.
Is there any logging in your router, where you could see why your packets are skipped (or routed in the wrong direction) by the router.
There is logging on the router and I’ve turned on Site Blocking - the only way I can get it to display useful information. So when I visit a site on this laptop (Mac), I get the message:
[Site allowed: www.google.com] from source 192.168.1.3 Wednesday, Sep 09,2009 23.11.56
But when I try to access google from my Linux laptop (the laptop on which I’m viewing the router log through firefox), I get nothing. Nothing appears in the log. Absolutely nothing, so unfortunately no help there!
Some other information about the router that might help (taken from the router web interface):
LAN TCP/IP Setup
IP Address: 192.168.1.1
IP Subnet Mask: 255.255.255.0
Use Router as DHCP Server: "YES"
Starting IP Address: 192.168.1.2
Ending IP Address: 192.168.1.51
I’ve also tried reserving the address 192.168.1.2 for my Linux laptop using the MAC address, but this doesn’t help (has no effect - it already had IP 192.168.1.2 anyway).
So in summary, my laptop is definitely connected to the router (192.168.1.1) using IP address 192.168.1.2, but there is nothing in the log when I try to connect to an outside website.
Any more help and advice will be greatly appreciated. Thanks in advance,
