Hi @vcit ,
My mistake, apologies.
Check that the antenna cable shown on the right in your images is still connected at both ends of the cable.
The antenna connection near the top right side of the battery looks OK but the other end is obscured under the speaker module. I think that it is connected to the USB board
If the antenna connection is faulty then you will get the symptoms that you describe i.e. WiFi only works next to source of signal
Hi @vcit
It may be that the WiFi cable is damaged internally as it is actually two wires like a co-ax cable. An inner conductor (which is the antenna wire) and an outer braided shielding wire.
Also make sure that the flex cable from the USB charge board is plugged in correctly. I’m not 100% sure but I think that the WiFi chip is on this board next to where the antenna plugs in. Usually the WiFi chip is close to where the antenna plugs in so that the maximum amount of signal is provided to the chip and I can’t see a chip near to the other end of the cable up near the battery in your image
If you have a DMM (digital multimeter) and a thin enough wire to connect to the inner conductor, you can use the meter's Ohmmeter function to test for continuity of the inner and outer conductor from end to end of the cable.
If you don’t have a DMM or if the cable tests OK then you may have to start replacing parts to try and isolate where the problem is.
If you can’t test the cable then first try replacing the WiFi cable (supplier example only).
If the cable tests OK with a meter or if the WiFi doesn’t work OK with a replacement cable then try replacing the USB charge board (supplier example only).

Thanks for answering. The model in the guide is the N7100 and mine is the N7105, the N7100 and N7105 apparently have different motherboards. If you look at the picture I uploaded, you will notice that the antenna hole is not on the left.
