LINKSYS E3000 Wireless Router has stopped working abruptly

p_s_92 564 52 March 3, 2012 at 06:36 PM
My LINKSYS E3000 Wireless Router(simultaneous Dual Band Gigabit 802.11a/b/g/n 2.4GHz / 5GHzrouter) has stopped working abruptly and I cannot access the Internet using it. It worked fine for till now but does not work now. My computer and network connection(ISP is Comcast) are fine as I can connect directly to Internet it using the modem something like

Cable from Comcast---> Cable Modem --->Ethernet Cable to Computer

works

Neither the router's wireless and wired components work. I tried connecting a ethernet cable from modem to router to computer but that also did not work.

Cable from Comcast---> Cable Modem --->Ethernet Cable to Router---->Ethernet Cable to computer

does not work. Did power recycle on modem, restarted the computer but those steps also did not resolve it.

I have tried doing the power recycle on the router and using Cisco connect but that did not fix the issue.

I did not update any firmware recently which could have caused this. The router was purchased before some 45 days from Newegg.

Any suggestions would be appreciated.

you can try factory reset; if it does not help you can try to RMA

When you say neither the wireless nor wired components work, do you mean that you don't even get an IP (assuming you're using DHCP) or that you do get an IP but you can't reach the internet?

Can you ping the router?

Are you using the stock firmware or something like tomato?

Thanks, will try that. RMA is ruled out as it is more than 30 days so newegg.com refused it. They want me to contact Cisco as it has 1 year manufacturer's warranty. Will post in Cisco forum.

I do get an IP(but it is 192.168.X.X) and am using DHCP but cannot reach the Internet. It mentions Access local only. The network map(when I use the router) is something like

PC---->ciscorouter but not connected to the Internet

Whereas it should be

PC---->ciscorouter -------------> Internet

The computer can connect to router but not the Web using it. The network access is local only rather than local and Internet.

check you cable do you have all lights on ?
are you running in gigabit mode or megabit?
looks like it does not send proper gateway info?

can you run ipconfig /all and post results here?

just backup your config and do factory reset.
you can try to use cisco software from your disk to reconfigure router;

you can try to disable dhcp and setup static ip on your computer
if you are going to get a replacement you may want to put a small fan next to it.

this router has some problem with overheating due to bad design.
I am running my with small fan.

Yes, it has the required lights on.

I did not configure it for either but imagine it is in megabit mode. Network speed is 54Mbps but access is local only instead of local and internet.

It was before so why suddenly could it be having issues?

Quote from dude2000 View Post :

Not right now near it, but this is what I recall I had.

Wireless media adapter
IPV4 address 192.168.1.2
Subnet mask 255.255.255.0
Default Gateway 192.168.1.1

Rest(Wired, Bluetooth) are disconnected

Did factory reset but that also did not help.

Cisco connect is installed on the machine, it tried to reconfigure the router after factory reset but could not.

Ok, will try that. But, how would that aid me? And, how do I know which IP to use if I am doing static?

Thanks, but wouldn't getting a refund from Cisco(if they will do it) and getting another one
a better option?

I suspect if overheating is an issue with this model, then this is what might have caused it to malfunction.

Thanks for your time and suggestions.

Somewhere in the web interface is a place to see the public IP... have you tried doing a refresh there? (if it has the option)

You may need to shut the modem down for a couple of minutes between switching from modem --> PC and modem --> ciscorouter. This is because the ISP might be using the MAC of the PC and it needs to re-initialize with the MAC of the router.

Also, can you ping the internet by IP rather than hostname?

ping 4.2.2.2

for example

Did you remember to power reset your modem after switching it from your computer back to the router? Cable modems won't hand out new ip address to another MAC device until it is rebooted. Are the activity lights on your router and model blinking?

After you have done that. log into your router. browser -> http://192.168.1.1 -> status tab
This should be your WAN IP info page. If you're not getting a proper ip address on this page then there's something wrong with your connection between router and modem, possibly the cable. If you are getting proper ip and network info on this page then it might be your computer.

Right, you will have to go through Cisco, but it is still called an RMA. From the sounds of it you are tried to do all this trouble shooting wirelessly. Have you tried doing it directly connected with the wire?

Well, my IP address if I connect directly using the modem is 64.X.X.X
On the WAN IP info page, I see 192.168.1.2

The ethernet cable which connects the modem to router is fine. I used it to directly connect my PC to modem and can get connectivity.

No, computer is fine, else I would not be able to connect like
Modem--->Ethernet cable--->Computer

Thanks for your suggestions.

but no connectivity.

That WAN IP is not correct. It should be a 64.x.x.x address.
Do you have anything between your modem and router?
