I have a tad odd internet. I've got a router in the living room over which wireless connection is completely fine. However, the whole computer setup in the study has no wireless network card, I think. I just doesn't detect wireless connections. So the way the internet people set it up was having a Cisco WET610N connected over a cable to a cisco E4200 router. I'm not sure how it works, but it also raidates a seperate wireless connection for the other side of the apartment, while bieng convenently close to the computer for an ethernet connection.


For some reason, however, the connection dropped last night. The E4200 router was reset and it worked fine for a while. Then it dropped, and resetting anything doesn't work. Trying to connect wirelessly the router yields a DHCP lookup failed. The ethernet connection tells us that there's an "unknwon network", while windows troubleshooting says that the router has no valid IP.


What I've tried, which is admittedly not much, as I'm not much of a computer guy.

The computer is a windows 7 by the way, with a "realtek PCIe GBE Family controller" for a network adapter.


ping on the ethernet connected computer gives host not found.


I tried going to the router's page (ipconfig on the computer says that the default gateway is, which just times out.


Finally,  since the WET610N is blinking an amber light on the power, I tried connecting to it. That ends up with no default gateway at all.


Any help would be greatly appreciated! Thank you, and have a good day!
