A multicast issue with the switches, impacting the cluster behavior. Wireshark windows thing connector unplugged update#(I'll update this list with new suggested issues): To narrow down the circle, I'm specially focusing on networking issues, but every idea is welcomed.ĭo you think it would be useful to elaborate such list? What issues do you usually find? Of course, assuming the firewall side is properly configured (which would be a "firewall issue" but due to a bad configuration). But what I would like to point is not the troubleshooting, but the issues themselves. Probably there are several simple tools that one should use first, like: traffic logs, fw monitor, tcpdump/cppcap, etcetera. It's a quite generic topic, and in terms of troubleshooting it's probably even more generic. I'm looking to build a brief list of typical or somewhat frequent issues we face, where "the firewall" is reported as the root of the issue, but finally it isn't. A security gateway (a "firewall") do a lot of "intelligent stuff" more than just routing traffic (and -in fact- many network devices today do also "a lot of things") so I understand there is a good reason for thinking about the firewall but, at the same time, there is a big number of times where it's not anything related to it, or when it's not directly related. If it still does not work, ask them to replace the router.We all know that "the firewall" is one of the first things people blame when there is a traffic issue. If it still does not work, unplug the other internet connection and repeat the test. Please ask the router admin to disable WAN balancing for a while (unplug one internet connection). Well, the whole behavior (as you described it) does not make any sense and thus it looks like a bug of the router to me. The computer I said that can connect to internet without any problem is Macbook Air. That makes the router more likely to be the source of the problem. Wireshark windows thing connector unplugged Pc#Last thing is I borrowed my friend's desktop PC for test, and it's have a exact same problem with mine What are they balancing? Several internet connections? According to google the RV042 has two WAN interfaces. No, it replicates your problem with IE for a yet unknown reason.īut I see that they're using Linksys RV042 for load balance, is this relate to my problem? I tried Fiddler, but when I use Firefox it's doesn't show a web page, just only loading like the other programs like IE, Is this normal? If it works with the proxy and with Firefox, and you already replaced your router, then go ahead and ask your ISP regarding this problem. It could also be a transparent proxy at your ISP that causes problems with certain kinds of 'User-Agent' headers.Īnother test would be the use of a local proxy like Fiddler 2. I have no explanation for this kind of behavior (maybe there is some kind of Layer 7 filter enabled), so I recommend to replace the router for a test. So, I conclude the problem is somehow related to your internet connection. Maybe some web servers have a problem with that, although that would be rather unlikely, as a lot of people would have similar problems then. The only thing in common is your router and the version of Internet explorer (sent a 'User-Agent' string). Wireshark windows thing connector unplugged driver#If this is really a plain Windows installation I would say it is a problem with the network card driver.īUT you connected via LAN and Wifi, and you can download via Firefix, so a driver problem is rather unlikely. Data exchange stops in the middle of the communication (large parts of the javascript text missing). There is something weird going on while you download via IE.
