problem is sometimes while download is finished the connection goes down.

even pinging the routers Ip: 192.168.0.1 gives me time out
Answer #1
connected to the router by WiFi or ethernet?
Answer #2
ethernet..regular cable
Edit: router is Dlink DIR-100 Firmware Version : v1.12
Answer #3
try replacing the cable, check to see if the router is intermittently turning off and back on again. Might be overheating from the high activity, it shouldn’t do this so make sure the airflow around the router is good. The time out when you ing your router point to something internal (not your ISP). Failing this try re-install/updating your network card drivers, then your routers FW.
Answer #4
well router is fine cause my other roommates have no issues with it
this is what i see in error viewer on the pc
The value for the NwlnkIpx parameter Export was illegal.
The NWLink IPX/SPX/NetBIOS Compatible Transport Protocol service failed to start due to the following error: The parameter is incorrect. TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.
The device, \Device\Ide\IdePort1, did not respond within the timeout period.
dunno what the problem is
Answer #5
me neither, a guess would be a setting in your registry needs changing
