This problem still occurs if i use my ISP DNS servers and my computer is the only one connected to my LAN (password protected) I've used both wireless and wired still the same thing SOMETIMES it will start working. But like 20-30 mins later it starts acting up. I've used different laptops to test to see if there was something wrong with my wireless card or ethernet port. But no it works fine but its the same problem and this isn't my first router that this has happened to. I'd used to get disconnected completely and the router would randomly restart. This is very frustrating because my ISP or router company can't help they just advise me to un plug my router and plug it back in.
