can't access internet in fedora 10
recently I installed fedora 10 in my system but it doesn't allow me to access to the internet. Every time I start Firefox it shows that Firefox can't connect to the server. I unchecked the work offline then also tried to, but failed. In network I changed my settings & given my ip address default gateway DNS1 DNS2 etc etc...But don't know why the default gateway value automatically selected as a subnetmask value. If I change it & saved it then also it didn't save. Like
but after apply ok
both values of subnetmask & default gateway are:vvv.vvv.vvv.vvv
I using fedora 10 & any help regarding this 'd be much more helpful.
I also deactivate network manager as I use a broadband service with static ip address. I choose to use network service.
