[Q] Anyway to boost Wi-Fi Connection? Oh, and Root? topic

I'm running the lollipop update on my 16gb shield (which I'm surprised it's not 5.0.2) and I get a very poor Wi-Fi signal on both my 2.4 and 5ghz Wi-Fi signals compared to my other devices. Is there anyway to give the antenna a little bit of a boost instead of having to reposition my router? Also, is rooting the shield tablet worth it with unlocking the bootloader and then rooting?
