When I restart the computer (with the router on all the time) I cannot access the internet. Once I have carried out the router off/on routine I can then log on to the internet as usual for as long as I like. The connection does not drop until I log off the computer ( and leave the router on). Then the next time I start the computer the whole thing starts again. > I don't understand why switching the router on and off helps in this > instant.

I have just restarted the computer (but not done the router routine) and I cannot access the internet although the icon on the panel tells me that the network is up. > > Also can you do a "ps -aux | grep dhclient" and see if dhclient has > backgrounded properly and if you have a load of them running or > something. dhclient should sit in the background after getting the first > lease then release at the required interval. > Here is the output [neil@localhost ~]$ ps aux | grep dhclient root 5117 0.0 0.1 2096 992 ?

As root I have just done the ifdown/ifup routine to no avail. Now I will do the router routine so that I can email this.
