cisco 871 games keep dropping or lagging out

Not sure if this is the right place to put my problem but I have a problem with my cisco router and I have no clue what is causing it. I tried using QoS and the problem still occurs. Any time during a game or streaming video I would lose connection for example in wow I will be able frozen can't cast or do anything. If I'm watching a streaming video it would lose connection.

I had a linksys WRT54G and it would work fine. No disconnects or freezing during gameplay.

Also if i'm using pandora it works fine. When I get a DC or frozen game I can still surf the internet.

here is my config.

Try to remove the following commands from int fa4:

ip nbar protocol-discovery

ip inspect MYFW out

service-policy input sdmappfwp2p_MYFW

Try this both one by one or in any valid combination and see if the problem disappears.

This will lower your security but if one of these is the cause, its the only way to find out.

In general, always triple-check your security settings when something from the Internet is not working.
