Hi Pinguino1. I have no streaming between the computers, only one share folder on each computer for moving files when needed. Network and internet traffic is quite low here. I disabled IPv6, and I'm waiting to see if that has any effect. I won't know for certain until tomorrow night but I'm not too optimistic about it. When the internet is about to slowdown or stop all together it's almost as if the router loses is ability to lookup host names. It seems sub domains go first, e.g. ad1.cnn.com, then top level domains fail to resolve a few minutes later. Very strange effect it has on the router. Also, some web sites will load as if they are mobile versions. Everything on the left as links and no images. I should say that without rebooting the router, the net/router or DNS function will come back if we wait approx 10-15 minutes. When this first appeared I thought my ISP's DNS servers where having trouble but after a few days and switching to OPenDNS, I realized it wasn't the ISP or the DNS servers. This happens with a new router also. One other weird fact, this does not effect online gaming if it's already being played. If my son is playing COD online, his ping is still excellent while the other PC's can't browse/lookup hosts or it's very slow. If he stops playing he can't lookup hosts either. Same thing if he is on runescape and playing. I'm thinking it's because the games don't use/need the DNS lookup as they already have a connection to the IP.. strange. BTW all the computer are clean, no unknown processes on any of them. This definitely has something to do with DNS function. A download already in session will get good constant MB/s speed... once a connection to the desired IP is made. I have not tried typing an IP directly into the address yet when the net bows out but I will try that next time it happens. I also switched everyones network adapter to use opendns servers without being assigned one from the router as I thought this was the problem at first, (the router's ablility in the DNS dept). Still the same results.
