Okay, I left my computer on sleep mode this morning. When I got back my mom said she accidentally hit the power cord/power outlet that my router, modem, and PC is attached to. So in effect my all the devices were shut off.

Now, after turning them all on, I cannot get internet through my router both wired and wireless. The network used to have a name. But now it just says "Unidentified network". I have a android device though and it can still see the wireless network and says "Signal Strength: Good". It just can't connect and stuck at "Obtaining IP Address" phase. I also cannot access the router page through 192.168.1.1. I also cannot ping 192.168.1.1. Now I just typed this with the modem directly connected to the PC.

I have a WRT54GL router, brighthouse internet, and windows 7.
Let me know if you guys need more info

Here is some info about the local area connection adapter connected to the router:

Don't know why default gateway is blank, probably part of the problem.

These are the things that I have tried"
1. I have power cycled it many times. It has not fixed the problem.
2. Tried release/renew but error occurs saying: "An error occurred while renewing . . . unable to contact your DHCP server"

Hopefully someone can help! thanks!

Can you try statically configuring your computer - 192.168.1.2 as your IP, 255.255.255.0 for the subnet and 192.168.1.1 as the gateway. Then try to get to the router interface that way. (You can either leave the DNS blank or just use 8.8.8.8 as the primary)

If you are still unable to get into the router after statically configuring your desktop, then try to do a reset on the router itself. Press and hold the reset button on the back of the router for 30 seconds, continue holding and remove the power for 30 seconds, then reapply power while still holding the reset button for 30 seconds.

This should bring you back to a default configuration. Try getting into the router again - If you are still unable to, then you probably have a bricked router, just go buy a new one at this point.

Sometimes a power bump can be the death to routers, some are more sensitive to input power than others. When power was reapplied, there could have been an over-voltage that caused it to fry.
