Ok I got Cavalier DSL about 2 months ago. I've had problems getting a router to work properly with it the entire time. I have 2 D Link routers one is a DGL-4300 the other is a WBR-2310. At first I thought it was a problem with my router so I exchanged the WBR-2310 and still had the issue so then I bought the DGL-4300 and its still an issue. So basically I set up everything and I connect my DSL modem to the WAN port and connect all my computers to the wireless connection yada yada. When I renew the IP address I can make one connection to the internet weather it be a messenger or a webpage. After that only that connection will work I can browse that webpage as much as I want but I can not go to another web page. I called Cavalier about it and they said it was a problem with my router and to call the router company. It works flawlessly if I have the modem connected straight to the computer but through wireless or wired ports on the router from any computer in my house it does what I described previously.
