Can't access the internet.

Post by groundzero348 »

As of today I can't access any websites via my router. I have a wrt54g-tm. It had intermittently not allowed me access in the past. I have been using 1.3.7 for a while now without an major problems other than the intermittent inability to access the web. The odd thing is that utorrent on my computer is still using bandwidth so the problem seems to only be with the web. I spent the last several hours doing factory resets and upgrading and downgrading firmware to no avail. Can ayone help me with this?

Thanks,
Matt

What version are you using now?

If you know how please get to the command line of your router and post the output of the following commands.

iptables -vnL
iptables -vnL -t nat
iptables -vnL -t mangle

Also a screen shot of your status screen would be cool.
Linksys WRT1900ACv2
Netgear WNDR3700v2
TP Link 1043ND v3
TP-Link TL-WDR3600 v1
Buffalo WZR-HP-G300NH2
WRT54G-TM

I'm using 1.3.8. At times I won't be able to connect to the network at all even though I can see that its broadcasting.

Here is the output from what you asked for and the screenshot. This seems to happen intermittently so I have no idea whats going on. However I have also noticed that while it only rarely completely cuts off my internet access my lag will spike through the roof when I am playing on my ps3 and it will take a long time to access webpages. Thanks for the help sorry I didn't reply sooner but the problem seemed to be resolved for a while and then it happened again last night.

Re: Can't access the internet.

Post by pbix »

Can I assume the data you posted was taken while you were having the issue? I cannot see any problems with this information. I use the WRT54G-TM myself and have never had such an issue.

You never mentioned how you get out of this situation. Knowing how this situation is resolved might give a clue.

Is it possible that this is an intermittent problem on your ISP's side of things?

I see you are using quota's which is something I do not use. While I have never seen a report of problems with quotas you might try disabling that as well.

Other things to try the next time it happens.
ping your wan gateway 128.208.47.100
ping your DNS server.
post a screenshot of your connection table and your status page. Did you WAN IP change?

The key to solving this is some detailed investigations while the problem is happening.

Thats all I can think of and good luck.

Re: Can't access the internet.

Post by groundzero348 »

This data was taken immediately after the issue had cleared up.

Usually nothing I can do really speeds up fixing this issue I just have to wait it out. Although this time resetting the wireless adapter on my laptop would let me access the internet for a few seconds before it went out again. I would suspect my laptops adapter as well except this happens for several different devices , my laptop, a PS3, my girlfriends laptop ect.

At times when this happens sometimes I cannot reach the router at 192.168.1.1 at all. I've triend power cycling it and changing the firmware but that doesn't seem to have much of an effect.

I would suspect the ISP except I can disconnect the router and plug the Ethernet into my laptop and it works just fine.

Next time this happens I'll try what you suggest. How likely is it that this is the router hardware itself going out?

Thanks again for all the help.

Hmm,

Well screen shots and iptable dumps while the router is working are not very helpful. You need to get these while the router is not working.

It seems to me that it is very likely some kind of hardware issue. There are no know firmware issues like this.

Another interesting place to look would be the dmesg and logread outputs immediately after a reboot. That is of course while the router is not working. If the router starts working again then these are not helpful.

How can you update the firmware when you cannot access the router?

Might be the cable between the modem and the routers.

Or you can go buy a new router on Ebay for $50 and be done with it.

Dang I was hoping it wasn't hardware related oh well.

How do I get the dmesg and logread outputs?

I can't update the firmware unless the router is at least intermittently working.

Thought it might be the cable too so I switched cables a couple times with spares I had lying around.

I think I might try and get you the outputs when its not working one more time before I throw in the towel and get a new router.

Just type "dmesg" and "logread" at the command prompt.

Pipe the results to a file. You can practice on your router while its working.
