Repeated random internet loss
« on: October 02, 2010, 07:45:02 PM »
Hello.  I've had some issues before, so I figured I'd come back and try again.  Trikein!  Furry!  Heeelp!

Here's the thing:  I have a problem with the router intermittently losing internet access.  It will have no problems with pinging local IPs, but when I lose internet Windows says there's a DNS problem and the router cannot ping the DNS I have it set to.

Some background info:  I called Time Warner Cable and had them help me set it up.  I removed the router, got the DNS servers listed for Time Warner (they confirmed those were it), and set those up in the router's options for Primary and Secondary.  I've also tried using the Advanced DNS though, and it loses those DNS servers as well -- intermittently.  Here's the setup right now:

Connection Type: DHCP Client
QoS Engine : Active
Cable Status : Connected
DNS Status : Online
Network Status : Established
Connection Up Time : 0 Day 0 Hour 17 Min 44 Sec

Authentication & Security : 

IP Address : 76.174.198.215
Subnet Mask : 255.255.240.0
Default Gateway : 76.174.192.1
Primary DNS Server : 209.18.47.61
Secondary DNS Server : 209.18.47.62
Advanced DNS : Disabled

Another issue I'm having is the wireless laptop is suddenly having some serious issues staying connected, even if my desktop is fine.  Another example, not sure if the two problems are related...

Well I will need to research your previous post to freshen up a bit, but yea..Welcome back :-)

Ok, well a DNS issue atleast is a defined problem, so thats good. After reading what you said, here are my questions:

1. "but when I lose internet Windows says there's a DNS problem and the router cannot ping the DNS I have it set to." Could you provide the exact error verbatim?

2.  "Another example, not sure if the two problems are related..." What is that ping from and to? Router to laptop?

3. "Also not sure what caused the bolded anomaly of 80ms difference. "A latency spike can be caused by several things. Do you just see this from router to laptop? What about wired connections? It could be how the router is prioritizing DNS traffic. I found a bug with DNS relay a while ago with something similar. I think DNS goes from TCP to UDP when the response is over 512b. I don't want to start giving randoms things to try though without know the info above, but yea, I have some idea's

1.  "There may be a problem with your Domain Name Server (DNS) configuration. Windows failed to find the well known host "www.microsoft.com" using DNS. The server may be down."  When I see that, I cannot get the router to ping the DNS address, but it can still ping my wired and wireless connection.

2 and 3.  The ping I displayed was from the router to the laptop (wireless).  It does not display the spikes toward the LAN, nor does it have ANY failed attempts.

Part of me wants to suggest turning off DNS relay, since if thats failing, that might explain why you lose connection to your DNS servers. However, DNS traffic is usually TCP over port 53, while a ping is ICMP traffic. I could see DNS relay blocking or delaying TCP, but ICMP? Then again, theres another bug which effects domain look up on tracert when DNS relay is enabled so...they could be related. I just don't know how. Oooh, this is a good one. I am going to have to chew on this one. Good info though. Maybe some sleep will help. I will look at it tommorow morning.

Oh, and I've also noticed that sometimes my computer displays that I do have a full connection.  It clearly states "Local and Internet"... however it doesn't actually have internet.  I can try to hop on a website and it'll time out.  And I can go into the 4500's Tools and ping anything outside without getting a response.  But the router can still ping the IPs of the local comps.

Sorry, I am actually doing the testing for a piece of Dlink hardware. Cant say much more but it has me very busy. In a good way :-)

Anyway my thoughts:

1. Local is when it connects to a DHCP server, and Internet is when it has a DNS suffix. So that might mean your connecting to DNS, but you can not query it.

2. Next time it happens try to
A. Ping a known IP (IE 173.194.34.104) from the router
B. Ping that same IP from your computer.
C. Ping your DNS from your router
D. Ping that same DNS from your computer.

3. I could see using static DNS causing problems, since technically they could change at any time. Granted, it usually doesn't happen all that often. But if your ISP is doing who knows what, it could cause issues like that. However, if your having the same problems with AdvancedDNS, I doabt its that.

4. When I did a google search, it seems thats a problem alot of people get when their winsock needs resetting, or dns cache needs to be flushed or some other problem inside your computer. But before we do a 180, and go down that road, are you having the problem with all computers, or just that one?

Cool beans on the new hardware!  Hope it comes out well!

Ok, the internet loss is happening with both computers, though more frequently when both computers are online at the same time.  For instance, I can play World of Warcraft or StarCraft 2 alone and only disconnect a few times, but if my girlfriend logs in as well we start losing internet more frequently.

The other portion of my message, where I ping the computers' IPs, only has an issue with the wireless connection.  Pinging my wired connection shows no issues, but pinging the wireless has those anomalies.  Here's another one I did right now for it.

I should point out that the wireless is in the same room as the router, as is my desktop.  We about 4 feet from each other, the router mounted up on the wall.

Do you have this problem if you save off your current configuration to file and do a factory reset? Your on good FW. I don't see a need for upgrading FW right now.

Ok, sorry for the delay -- I did a factory reset and then reloaded my configuration.  Gave it a few days, and I haven't seen us lose internet and end up "Local Only", but I'm right back to us disconnecting incessantly on World of Warcraft (see http://forums.dlink.com/index.php?topic=14325.0 for reference).  Grrr

Sounds good on the Internet disconnection. Hope it stays working. I'm wondering if there is a possible setup configuration issue having to do with the WoW gaming though. Have you gone thru all the settings and made sure they are set up correctly? I presume you have been using Gaming and or Gamefuel? Wheres Tricky when you need him.  ::)

Actually, no I haven't been using Gamefuel or Gaming.  The problem we ran into with that is it couldn't handle having the same info going to two separate computers at the same time (like when my girlfriend and I were in a raid instance together) and we'd get repeatedly dropped.

What happens if you put both PCs on Game fuel and put one of the PCs on Gaming? Gamefuel should be able to hand both PCs however you can only use one PC in gaming...
