Chosen Solution

I followed a guide from here, what doesn’t say anything about this, so this happened:

Is it a WIFI antenna/booster? Where can I get a new one if that’s possible? Is it important for the perfect working order, can I use something else for (wire etc.)? I asked straight from Lenovo, they don’t let me know. I also asked the Lenovo forum with no any luck. Thanks for any help guys. I couldn’t test it yet, I’m waiting for a new battery.

It is strange and interest as well…the tablet just works fine without that part.
