Re: Xbox Live
My first guess would be your router, that is assuming you are using one.
If so and if able try connecting your Xbox directly to your modem and see if that fixes it.
My guess would be that either yours, your friends, or both routers are blocking one another. Make sure that you NAT settings are not on either strict or moderate and see if that helps.
Either way if it does work you may have to constantly tweak your router.
