automatic DHCP apparently does not work properly – only google-related sites can be accessed through a browser(mail, search, reader) and nothing else. i even tried accessing my router (192.168.1.1) through a browser but when i do so, the page stops and nothing can access it (even windows, fedora on another computer) until the router is turned on again.
Did you just say “the page stops and nothing can access it (even windows, fedora on another computer) until the router is turned on again.”
Sounds like your router is on the blink.
Try a factory reset (Not just a reboot of the router). The reset is usually accessed with a needle and a tiny access hole on the rear. You do need to know all your settings though.
Is this a new problem or an old one ( has it ever worked? ) When did the problem start? Wired or wireless? What is the output of the following commands?
ifconfig
arp -a
netstat -rn
Are there errors showing in dmesg?
Your symptoms are all over the place and don’t seem to point to a single problem. I would concentrate on getting reliable communications with your router first and then worry about what’s beyond that.
