network connection disconnects, no http access but can ping

[rookie1010]

Hello,

i have got a wireless router at home.

every few days, the net connection seemingly snaps. when i visit a site, the firefox browser says there is no connection and i have to restart my router and my machine to get the net connection back again
but when i ping the site, i get a response. can you guys tell me what is happening, is there some way to restart my connection without restarting my machine, and also my machine. is it some sort of malware within my machine which is flooding the network and hence i am not getting any http connections.

is there any way to check if my http connection is down but not the rest of the network?

First try to connect directly to the modem to rule out Router problems.

If you have few computers that are network connected check if the File transfer is working once the Internet is down.

This program can help in monitoring the TCP/IP stack if the Internet goes down due to Malware it would show the activity.
