Wifi signal become very weak

[ithinkunome]

Today I dropped my galaxy s7, everything is working fine but wifi signals are very weak now. It just says searching when I open my wifi.
If I move very close to router than my mobile can detect it and connects successfully.
Any help would be highly appreciated.
Thanks.

Could be the WiFi antenna has become disconnected or damaged. If so, disassembly and professional repair required.

Can you please share an image which shows where the wifi antenna is in galaxy s7 ? May be by pressing that area it starts working in case of loose connection.

Look at ifixit.com that should have all details for S7, including antennas. You may not be able to press too hard, because this phone is glass front and back, and not plastic.

Pressing hard enough to actually do something like re-seat a loose antenna connector to the motherboard would require quite a bit of force. Enough that you could damage nearby components and enough that if you're pressing in the wrong place you could do something like physically damage the battery (very bad thing to do).
With phone like a S7, this requires partial disassembly to get to the insides with the additional factor being there's a lot of waterproofing measures added to this model (special seals, bushings, etc.) so to do this at home you do need all the correct tools, and a replacement kit with new seals and such.)
