Yo Nikita, i basically solved the WiFi issue by opening the tablet and put the antena on the outside of the tablet (i put the adhesive part on the outside of the tab and I put the the plastic flip cover on it. The antenna didn’t needed to be soldered since it was a little connector like for laptop wifi cards. The problem was the alloy shell that was blocking the signal (plus my house have thick walls in top of that)
In the process i fucked up the power and volume rocker (when removing the adhesive on it it simply teared the very flimsy connector) so i soldered a DIY power button that i put as well on the outside of the tab. WiFi signal is now outstanding, the look is completely homemade, now the little issue is the speakers but you basically use your tab with headphones anyway.
Overall great tablets, great LCD, good touchscreen, great performance and all connectors work great. I bought it 120 euros on gearbest and even with the DIY stuff it worth the deal
