One of the antenna cables cutted and solded. No WiFi connectivity.

Hello.

Few days ago, the sim tray of mi old iPhone stuck inside, so I had to disassemble it.

I had a lot of problems to do it, and, in the proccess I cut one of the antenna cables, the one that is connected in the middle of the antenna ribbon sheet.

Edited: Read the actual situation below the first image.

The cable is cutted very closed to the metal cable support in the side of the phone (see the arrow in the photo), and I'm afraid that if the cable make contact with the support, the comunications board (or something else) could be damaged.

What do you think there is the best solution for this problem? maybe cut the cable in the other side of the metal support, and replace this fragment with a new cable?

Thank you very much for the help!

I've read that the two wired are "the same", they are connected to each other and connect the comunications board with the antenna ribbon and the rear case.

I've solder the cutted cable and I've check with a tester the connectivity between the comunications board (1 and 2), the antenna ribbon (the two connectors) (3 and 4) and the rear case (5), all ok. The points are marked in the image.

The problem is that I don't have WiFi connectivity. The GSM coverage is fine, but none the Wifi.

I have the phone disassemble, and I have connected the parts with a wire.

Any suggestions about the Wifi coverage?

Thanks!

agree, these are made without using soldering. cannot remember correct phrazeing, basically, solder in this case works as shielding. means, no signal gets through. you need to get a new set of antennas. these cost about 3USD, ebay...

Thank you very much for your answers, I'll buy a replacement cable set.

But... I think that the antenna cable is solded to the metalic support under the battery, am I right?

You may try just cutting off the ends of the broken cable and running the new cable along side the remains of the old one. You shouldn't need to solder the new cable along the middle. Perhaps just use some thin tape to hold it in place.

Last weekend I received the new cable and replaced the broken one.

WiFi now works perfect.

Thank you for the answers!

These are coaxial cables. They have an inner conductor that carries the signal plus an outer ground shield. Your best bet is to completely replace the broken cable.
