Just upgraded up Internet upload Speed!

With 35/35 you shouldn't be getting much lag due to lack of bandwidth. If you upgrade it'll help. Keep in mind though your xbox wont be able to handle any speeds higher than 100Mbps (Up or down) as the network adapter only supports speeds up to 100Mbps.
Another thing you might want to look in to is limiting the bandwidth your other devices are using around the house. Your router should have some sort of settings in there to either limit bandwidth by IP or at the very least have an option called "QoS", which
essentially prioritizes internet traffic coming and going from each device connected to the router.

Hi I Hammer I. No matter what you upgrade to, the Xbox will only use 10/100. That is all it is capable of. It's like wireless network speeds... A wireless N adaptor can only handle speeds of around 40MB down, so thats all it takes from the network, leaving
the rest.

In short, if you upgrade to 65/150, then the Xbox will leave 55/50 spare for your family to enjoy their viewing.

Hope this helps!

Usually it's the opposite.... Services can't handle what the xbox can take.

Trust me, you can't overpower your console with internet speeds.

With Internet, you want a faster upload speed than download. 0.5 upload is near the bare-minimum for being able to play online and with BF4 being such a vast multiplayer experience with up to 64 players, your Internet may be stressing to keep up. Now,
I'm not saying it's your Internet's fault. BF4 is having tons of server issues ATM so it most likely is their problem. If, in a couple months, your still having trouble, you may want to upgrade to faster Internet.

I'm not sure what you want to be told. What are your download and upload speeds? Have you considered upgrading your internet speeds, or just plain old joining a private match on CoD with a friend and seeing if you have this issue? Honestly, sometimes I think
my internet is the issue, when it's really my lack of shooting skills. I've become better though.
