I have found replacement batteries and replacement WLAN cards but I'd like to know if there are upgrades for either of them? I want a longer lasting battery if there's one available and I want a gigabit speed card. My battery is starting to fail, so I'll be purchasing a battery in any case, but I'd like to be able to directly plug my CAT7 cord in and take advantage of the gigabit speed I have available to me. It's so frustrating to pay for that speed and not be able to work in what I'm paying for! Thank you to any and all who can help or have suggestions.
