I recently switched from Verizon Fios to Brighthouse Cable (time warner) internet as I was really not using all the bandwidth I was paying for before. Unfortunately I have had nothing but problems in the month since installation. After significant troubleshooting I have alleviated several of the internal network issues I had with the new modem, but am still having a DNS problem. Essentially at seemingly random intervals, or immediately if I open bittorrent, websites will not connect. I reset and renew and dns flush but nothing helps. Some programs will stay connected (skype, dropbox, etc) and some will not (games seem to suffer the same as the web browsing). Resetting the modem does not seem to help. The diagnostic report through windows troubleshooting says its a problem communicating with the DNS server. The router receives dynamic IP and DNS information, so I can't change anything there, but I put some free dns servers on this computer's list instead of finding them automatically. This did not help though. This leads me to believe this is some networking communications issue, not a problem with the DNS servers themselves. I disabled DHT in Bittorrent but the problems still occur, so I just have stopped using it. Oddly enough when I open it on another computer I can still browse the internet on this one, though the dns problems do become more frequent even when its open on another computer. To emphasize the point though: the problem occurs at seemingly random intervals regardless of what applications are running, I am only noting bittorrent since it seems to trigger the problem very quickly. From all of this it seems like there is a problem between the new modem and my network (its just two routers with dhcp disabled hooking up wired computers throughout the house). I would be very glad for someone elses input on the matter, hopefully its a simple setting, but could be a defective router or modem I suppose as well. Thanks in advance.
