Linksys WRT54GL + Tomato 1.27 firmware.. issues?

[Cosmin]

Hy. Since morning this router stopped to give internet for all connected devices (wired/wireless). All seems fine in terms of settings.. I can also connect to it wireless from laptop/phone but no internet.. an " ! " attached to wireless icon..

Wired.. it's an x and gives me : "DNS server may be experienced problems".

- Tomato firmware installed.. by connecting without router (cable) seems to be ok.

So.. my question is..where should I start to investigate?

 

Thanks!

It died? That thing is old as dirt. Just backup your config and factory reset and see if it works, if so then load your backup and see.

yeah I would reboot it - can you get to the gui? What does it show for interne/wan status?

[jrolson]

Stange, mine also stopped working today... Stopped sending internet.

 

I think there's a bug in the firmware.

 

Just rebooted the router and it works again.

Well.. here it is.. I can access it's interface.. all seems fine there. The wierd thing is that the icon show's connected even no traffic available (one drive cannot syncronize).

 

Just rebooted the router and it works again.

 

By using reboot from it's gui ? Nothing happened here :(

[+BudMan MVC]

what Icon shows connected - your OS icon.. that just says you connected to the router, if it says limited means it couldn't talk to the internet or dns is not working, etc. Was not able to see your image.

So status shows you good for internet on the router? If the reboot is not working on the gui - just pull the power plug on it, and then plug it back in.

[Cosmin]

Reboot works on gui..but nothing changed.. tried to pull it out and back and the same.. but I'll try once again now.. god knows :|

 

LE : tried to pull out..and back.. no luck :s

So says your connected to isp, how do you know its not a isp issue? Have you connected something else other than the router and that works? What is before this router? Are you natting or bridging on that device? You have it setup for PPPoE, and shows connected.. Have you called your ISP?

[Cosmin]

It's not an isp issue cause I've connected wired my laptop without the router..and works. So.. all that's before the router (one modem) is healthy. I quess the firmware should be reset or..update it with a newer version and setup all again ? Thanks for given support..

[+BudMan MVC]

So the router in front of this router is doing nat? Is it also doing PPPoE? In a normal setup with PPPoE you would have the device connected to the ISP doing the PPPoE login, etc. In that case your router your connecting should only be dhcp on the wan.

When you connected some other device to the isp device - did this device do PPPoE, or was it just dhcp?

[Cosmin]

There's a modem and a the router..and is not doing  nat..simply the cable from isp. in terms of settings nothing changed since it was ok.. but what should I look for ?.. probably something went wrong without human feedback :D .

the modem looks like this :

[+BudMan MVC]

Well that picture is USELESS, and most every dsl "modem" I have seen in the last 10 years does NAT.. You have it set for PPPoE, this makes me think dsl type connection.

So I find it pretty likely its doing nat. You blocked out every piece of info in your screen shot of your router status that would of given this info.

What is the model number of the device your router is plugged into? And when you plugged in your other device to this device - did you have to do pppoe?

What are the first to octets of your IP address on your router status page

Example

Also, I would make sure your modem hasn't changed its settings.

 

I have had modems decide to reset to factory defaults and take themselves out of bridge mode, which, of course, breaks the wifi router but would work fine if you plug your PC directly in.

[Cosmin]

Well..here is the info required. The wierd thing is that Eset updates it's definitions even internet is not working :|.. or just apparently ?

Thanks a lot for your time and solutions until now..

So clearly windows thinks you have internet, and your antivirus talked on the internet. And still did you have to setup PPPoE on the device you connected to your device to get on the internet - or just dhcp?

Can you ping that gateway under your IP address and mask for your wan - that would be your ISP gateway, first hop on the public internet.

example

budman@ubuntu:~$ traceroute 8.8.8.8

traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets

1 pfsense.local.lan (192.168.1.253) 2.433 ms 1.991 ms 1.952 ms

2 gateway.comcast.isp (24.13.x.x) 10.565 ms 11.359 ms 15.712 ms

3 te-0-5-0-8-sur04.mtprospect.il.chicago.comcast.net (68.85.180.133) 16.613 ms 16.615 ms 16.581 ms

Hop 2 is my ISP gateway. Can you ping it?

BTW hiding anything that starts with 192.168.x.x or 10.x.x.x or 172.16-31.x.x or 169.254.x.x is pointless - these are private and apipa addresses that are not routable on the public net.. That everyone uses - there is no personal info given a way from this if you let others see this.

example - here are some boxes on my network

budman@ubuntu:~$ arp -a

esxi.local.lan (192.168.1.40) at 00:1f:29:54:17:14 [ether] on eth0

pfsense.local.lan (192.168.1.253) at 00:0c:29:1e:18:ae [ether] on eth0

i5-w7.local.lan (192.168.1.100) at 18:03:73:b1:0d:d3 [ether] on eth0

What you going to do with those macs? Other than maybe looking up who the maker of the nic is from the first 3 numbers. Now if you want to hide say the last part of the mac on your wireless AP radio - ok, that is sometimes available to lookup location from if its in a war driving database.. Ie someone logged your wireless network. But your macs on devices on stuff inside your network is not anything you need to worry about hiding.

n the device you connected to your device to get on the internet

 

don't know exacly what you mean with "device connected to my device" but on the router II had setup PPPoE.

 

Can you ping that gateway under your IP address and mask for your wan - that would be your ISP gateway, first hop on the public internet.

 

cmd.. ping .. ? newbie on such things..

[+BudMan MVC]

so from a cmd prompt type ping and that IP, same with tracert. Start, run, cmd will give you a black box see below

so example

C:\>ping 8.8.8.8

Pinging 8.8.8.8 with 32 bytes of data:

3 9 ms 9 ms 9 ms 68.85.180.133

Try the IP address that is listed as your gateway in the picture showed off the wrt.

As to device

" I've connected wired my laptop without the router..and works"

So did you have to setup PPPoE on this - or did you just have it setup for dhcp? What IP did you get?

[Cosmin]

Tried to ping gateway (10.0.0.1) adress an gives me request timeout. It was with PPPoE cause isp gave me username & password for connecting. The ip that i get is : 192.168.1.146...

[+BudMan MVC]

So your gateway is is

"Tried to ping gateway (10.0.0.1)"

That is a private IP and not routable on the internet.. So no I would not expect you to be able to ping that ;) What about the tracert ?

Your private address 192.168.1.146 is what you get from your wrt router - not what you get from the ISP.

Still didn't answer the question - when you connected your laptop wired to the isp device - did yous setup pppoe on the laptop?? What IP did you get then - do a ipconfig /all from cmd prompt when this laptop is working - ping the gateway it shows. Tracert to 8.8.8.8 what do you get?

So have you bought/borrowed a new router yet??

[Cosmin]

- now I've connected the pc to the modem. and here are the details..

- haven't bought/borrowed a new router yet.. I'm still trying to find out what's going one here.. I'm pretty sure this oldie is still alive :|

- I'll try to ping..

[+BudMan MVC]

I can not see this image you posted.. Not sure if just me or if just something going on with neowin, but having a hard time with images in this thread.

The url to your image comes back 404

https://www.neowin.net/forum/uploads/monthly_09_2014/post-18459-0-20930900-1411821344.jpg

Well WTF now it is showing up.. Got to be issues with neowin

So you are setting up PPPoE on the client you connect.. what does a tracert look like to 8.8.8.8 from the client that works?

Then try and ping hop 2 or 3 in that trace from your router. Power cycle your isp device, wait til it fully comes back. Then connect your wrt and turn it on - let it fully come up and connect a client to it and try and ping and trace to that same IP.. What do you get?

[Cosmin]

Well.. here's the result from pc being connected directly (without router).  I'll try also what you recommended with it connected.

 

[Cosmin]

& with the router :/

[+BudMan MVC]

well that sure looks like you have internet to me - you ping googledns with you router - so what is not working??

Its odd that you have rfc1918 addresses in the path.. But you clearly are on the internet and can get out with that router.

[Cosmin]

this means there's something wrong with the settings on the router (tomato firmware).. username&password are excluded from the list but which should be :/ .. don't want to replace this router if it's still alive..
