View Full Version : Is my router dying or something?

I don't get this. Recently some sites have been crapping out on me, that haven't before. This happens on all the PC's on our home network.

I was just testing sites at random here.
linuxforclinics.org throws back a bunch of mysql warnings
modfree.org doesn't load at all (shows sql errors)
any SMF forum with reverse DNS lookup enabled takes at least 30 seconds to load any page.
some things on the Angry Nintendo Nerd website will not load properly.

BUT

At work, all these sites work properly (haven't tested all of them at work)
If I connect through a proxy (i.e. myspaceproxy.com) or Tor they work fine.
If I connect the cable modem directly to my computer (bypass the router entirely) all the sites work fine.

One thing I did notice, my WAN ip is entirely different when connected directly to the cable modem and when connecting through the router (in my testing, it gave me the exact same IP each time I was using the router, and a different IP from the router when I used the cable modem).

So here are my two guesses:
My router is messed up.
Something at the ISP is messed up, maybe for the random IP they've assigned me that I keep getting when I connect with the router.

Can anyone share some expertise here? I'm stumped.

EDIT: I should have mentioned, I've restored the factory settings on the router.

If there's ever any question about your router or your modem, just reboot them by power-cycling them. Unplug the power, wait 20 seconds or so, plug back in, wait for them to reboot and get going again.

Most routers have a reset button too, which you can push with a pen or other small pointy implement. That will do the trick without unplugging power.

Can't hurt to try it.

Firmware updates for routers can sometimes solve problems.

When you're plugged directly to the modem, you get an IP served to you by the ISP's DHCP server.

When you plug into the router, you get an IP served to you by the router's DHCP. The router gets the one from your ISP.

Did all that

Yeah, the reset button is a factory settings reset button, which I've done.

Done that too :)

I know, I was referring to the IP address that the router got, not the one that my PC got. I know my way around networking, but this one is stumping me.

What kind of router you got?

TravisNewman

Network Everywhere nr041

Piece of crap but it's served me well for a few years.

EDIT: I just tried DOWNGRADING the firmware, because... why not? That didn't help either.

Just getting the basics out of the way, in case you were a newb. So you get a different IP depending on which device asks for it? Router gets one range and computer gets a different range? That's odd, isn't it?

Not only a different range, a different specific IP. For example, every time I connected with the router the IP was 1.1.1.1, every time I connected straight to the cable modem it was 2.2.2.2

Obviously not the same IP's as I was getting, but it was significantly different. Not even near the same subnet, or even the same network. The first octet was different by 10.

And yes, that is very odd.

Have you tried viewing the page on a different pc?

yes, as I said in the first post, it's the same no matter which PC on the network I use.

I'm thinking it's a dns problem that router has setup to...

hmm... try making your router use opendns's dns servers

if that fails...

TravisNewman
April 9th, 2007, 05:33 AM
Yep, I've tried that too :)

Question....Does it show wrong on both Linux and Windows?

TravisNewman

yep.

Question 2: Did you call both your router's manufacture and your ISP about the problem?

TravisNewman
April 9th, 2007, 05:53 AM
No, I haven't yet. My ISP's tech support has never impressed me one bit. At work I'm on the phone with equipment manufacturers and software companies for about 3 hours a day, I've lost faith in them to an extent ;)

that's fine, I won't be getting on for a while though.

I have narrowed down all the possibilities I could think...try accessing the sites by their ip if possible also.

TravisNewman

At this point I'm thinking of buying a new router... I would like to have wireless, and one port on this one's built in switch is fubar anyway.

So if any of you have any ideas about how to fix this, now's the time to share :)

linuxforclinics.org throws back a bunch of mysql warnings
modfree.org doesn't load at all (shows sql errors)

The fact those two sites aren't working is very odd. (I'm an administrator on both sites, by the way.)

They are both hosted on the same server, so there may be a server problem. If you encounter the error again, could you please PM me any details of the problems you might be having? Also, on the linuxforclinics.org site, is it the forum that isn't working, or the whole site? The rest of the site is powered by Joomla, but the forums are SMF.

I'll get in touch with the owner of the server and see if there could be a problem there.

Thanks.

It's not a server problem, it's happening on my own webserver too. But only when I'm using the router, connecting directly works fine.

And it's not just those sites, there are many, many more.

If it works properly without your router I can only come to one conclusion... get rid of it.

If your router supports MAC spoofing, you could try enter your PC's MAC address in the router. See if your router then gets the IP address you would get on your PC.

Hmm. Well my only question there, I have to register the mac address of the cable modem with the ISP. Spoofing the mac of the router wouldn't cause that to mess up would it?

If your setup is like this:

CABLE MODEM ---- ROUTER ---- PC

then no, you wouldn't. Since you have said earlier that you can also connect your computer directly, I'm assuming this is the setup you're using.

In this case you can safely modify such a setting in your router, the only thing it does is to make it look for your ISP like this:

CABLE MODEM ---- PC

I'd rethink it if your cable modem and router are one device, though...

TravisNewman
April 9th, 2007, 07:24 PM
No, you're right, they are two separate devices. I'll give that a go this evening.

If that works, would you suggest just changing the router's mac address and see if that fixes things somehow?

altaaa

If that works, my guess is that the lease in your ISP's DHCP server is somehow messed up. That would explain why your router gets a completely different IP that your PC.

If it should work, just leave it like that. Once the lease that is registered to the MAC of your router expires (could take up to a week), you can have a second go at using the original MAC of your router.

But, not all routers support MAC Address Cloning. If your router doesn't you should call your ISP and ask them to release your router's WAN IP... Maybe that helps.

TravisNewman
April 9th, 2007, 07:35 PM
I'm pretty sure it does support that. I'll give it a go and let you all know. Hopefully I won't have to buy another router (but I was kinda looking forward to some wireless :P)

Hey! I think I've now figured out the problem!

I posted this question at Broadband Help, and I did get one reply.

I didn't sign up for an account, and in that case it shows your domain. If you notice, it says charter.com for the first post, and the post that I sent back to say that all was working, it says suddenlink.net

Well, the charter location in the area was bought out by suddenlink recently. I guess something got messed up in their merger or something. Either way I don't care, it works now. :)

That would explain the different IP range. Try in a week or two to remove the MAC cloning, so you can use the router's MAC address once again. Or just keep it as it is, at least it's working :)
