Total network failure and sluggish performance.
Posted on 2008-11-12
Our network suffers from sluggish performance, web pages take ages to open, intermittent packet loss etc.. Furthermore we lose total internet connectivity, this only happens say once every 2 days and only for about 60 seconds - but it is enough to annoy my boss!
The problem is very hard to track down, as it only happens intermittently - I did however manage to try to ping the default gateway (a Router installed by BT on a business pack - I can not even access the settings of the router) when a full network wide internet failure happen.
The first try, I could not ping the default gateway and got a "host unreachable" ICMP error message.
I managed to catch a network failure again, the ping this time showed 75% packet loss. This only lasts for about 2 minutes.
I now have to install a wireless network, but want to sort out any possible errors before I do this - so I have to call BT.
Now, to my question: Do I say to BT that I believe the router is at fault here? I mean there are many variables to this, but I do not know where to start to be honest. I could get them to come out and change the router, which is old. I mean if the whole on the internet went down - it is not a localised problem with the server, or individual workstations. And it could not be the switch? I mean, all the Ethernet ports on the switch could not go down at the same time.. Thanks for any suggestions on this one.
I know I should install Wireshark, but it would take me a week to learn how to use the program and interpreted the results - I just don't have the time for this at the moment (I will do that at some point though).
So, any suggestions. Should I call BT and ask them to come and change the router based on the fact that we keep losing our internet connection, all workstations, and I cannot ping the router during this event. What else could cause this and the slowdowns experienced.
