Cannot connect to router

[trinklest]

I'm a newbie to linux and ubuntu, so please bear with me

i am running 8.04 and i have a gigaset se567 router provided by ISP

it was working fine for two weeks until yesterday. i cannot access the internet or the router wired or wirelessly

also, my boyfriend's ubuntu machine will also not connect anymore. could it be an ISP issue? tech support insists that i use internet explorer which i do not have.

ifconfig produces

You do not have to use Internet Explorer. Your problem is that you the router has not supplied you with any details when you try and connect to it. Therefore the problem is between your router and computers, not the ISP or browser.

Have you tried resetting your router? You should try the power first and if that doesn't help how about using the reset button on the router to set it back to it's defaults?

i have tried unplugging and replugging everything and resetting the router to no avail.

Okay, it looks like a broken router then. Your problem is that it wont assign an IP address to your computer via DHCP. If your ISP supplied the router then they may replace it for you else they aren't too expensive to replace.
