Keep getting disconnected from xbox live party chat

So the getting disconnected from live part seems to be resolved thanks to some help here.

But I'm still getting dropped from private chats and party chats.

I am having the same issue and it's starting to make me become very agitated. Sporadic disconnects from XBox live when I am not actively playing an online game. If I am playing a single player game, Skyrim for example, within 5 minutes I am disconnected
from Live. If I am in a Party Chat I am disconnected from the chat but not Live. Then I have to reconnect to the Party. Or, my friend are booted from the party and not me...the party issues happen every 2-3 minutes or less sometimes. Starting to get very aggravating.

Then we can rule out the "map packs" as an issue. Could you tell me how you've setup your network equipment. Are you still using the Motorola SURFboard and the D-link router at the same time or just the Motorola?

just tried it and within about 5 minutes of connecting to a friends party we got disconnected again, my god this is so annoying
