My router / ethernet switch stopped working last night. How do I fix it?
I was surfing the web last night when all of a sudden I couldn't reload several web pages. I restarted the cable modem, but that didn't fix the problem. I then noticed that the network icon had an "X" on it. The diagnostic program suggested I might have an unplugged network cable. I checked another computer on the network, and it wasn't connected either. I then tested the internet connection by connecting the cable modem directly to the computer, and it worked.
Plug a computer directly into the modem. Browse to the modem's web page. Disable NAT. Plug your router back in the modem and your done.
Another thing is to call your provider.
I have cable and if the cable is interrupted, then my router becomes confused. I call comcast and through an automated phone call, Comcast resets it.
Turn everything off for at least a minute. Try powering back up.
If that doesn’t work try another ethernet cable.
If that doesn’t work call your provider.
I have linksys router with a cable connection. If I don’t power them down in the right order it doesn’t reset.
Read post #16.
I have a wireless router connected to my cable internet router also and have no problem. I have secured my wireless router so no one can use it close to me. Beyond that I have no idea what your problem might be.
Yes I unplugged the power then plugged it back in. I also rebooted my computer. The lights came on. I did notice the test light did come on when I plugged in the power but stopped working after about a minute.
Unplug both the modem and the router and shut down the computer(s)
Wait for a minute.
Plug in the modem.
Wait for it to recycle, allow at least one ninute and let the lights settle down.
Plug in the router.
Wait for it to establish a connection with the modem, Allowat least a minute.
reboot the computer.
Wait for the computer to establish a connection with the router. Allow at least a minute.
Try opening a browser.
I don't know your router and what private ip range it is using but its manual should show you how to use the browser to access the router's firmware so that you can check whether it has gotten an ip address from the service provider for its WAN side and has assigned a privae ip address to your computer from its LAN side.
I think you can replace it for less time and headach than it would take to try to fix (if it is actual hardware failure)
Is that a bad thing?
Excuse me are personal comments allowed here all of a sudden? Don’t you have to attach the vanity tag at least?
Was this working before and if so what changed?
The cable modem will use the IP address assigned by your provider. Your wireless router should take that and assign internal address (127.0.0.x).
It looks like you have a dead router/switch.
Did you try a different power outlet? I doubt that’s the issue, but it never hurts to try.
If that doesn't work, take a big hammer to the whole thing, and call me in the morning, after checking your debit account to be sure you can afford me.

You aren’t going to want to be connected directly to the internet for too long.
You will have to describe your network set up. You can get a double NAT error if your ISP assigns you a private network IP instead of a public Internet IP address. In that case they are using NAT for their clients. If you have a router at home to share your internet connection, then you have a double NAT situation with the ISP doing NAT (Network Address Translation), and then your home router doing the same.
You can also have a double NAT if you have two routers in your home, which is completely unnecessary unless you’re trying to firewall a section of your network from the rest of your home network, but I don’t know why you’d be doing that.
So, if that doesn’t help you, maybe you can describe your network set up in detail.
I am not familiar with Microsoft operating systems which I assume you are using. In Linux you can run this from a root prompt:
ifconfig
It will show you what connection there is on your eth0 which is ehternet connection and your localhost which is your loopback interface. I believe that the microsoft command would be this
ipconfig /all
I would follow the “reset everything” advice but make sure you leave the cable modem off at least 5 full minutes (at least that’s how long it takes my ISP to recognize I’ve dropped off ... that ensures I get a new IP when I power up).. if you have a Linksys WRTP54G router (or a few other similar models) they have a bug where a port will hang after xxxx IP connections are made .. a reset will fix it (not a power off but the reset button that reloads flash) but I usually just juggle wires into a new port.
That happens when the beeber is out of stunement. Stune it and you should be fine.
Okay, found your later post here. You should only be running one router.
Confirm that you have two routers and set the router further down in your network (probably your wireless router) to bridge mode. That will turn off the routing functionality.
It's not "bad"...just confusing.
