I have a network composed by:
28 x PCs
4 x Axis network cameras
2 x WRT-54G WiFi routers
1 x Apple Airport N
2 X Apple TVs
2 X D-Link 10/100 24 port switches
3 x ADSL Routers at 6Mbps each from the Telecom operator connected to the switches
All goes well and actually has been going well for the last couple of years, but since summer started and randomly the network "jams" and until I don't restart the DSL routers no networking functionality can be achieved, and computers can't see each other, etc... not just internet goes, but all the network.
If you look at the network devices ports or the switches themselves you see the less flashing like crazy (until reboot the routers). It's not internet traffic even, just like echo ping ongoing throughout the network that disappears after the reboot of those devices.
We've replaced them a couple of times by new ones without luck and since is a random thing, we can't never check until it happens...
Any idea of what could be causing this? At least how to determine what the problem is?
Note: I've sniffed the net traffic with Wireshark and found out it repeatedly produces the following: http://skitch.com/cyborg/fq6k7/dock
