WIFI signal is weak, which part should I replace

My iPhone 6 wifi is very weak unless I'm RIGHT next to the router. I've tried all the software fixes, and determined it's hardware.

Will simply replacing the antenna or the antenna cables fix it or is this a common issue where the chip on the mother board is bad?

If it's the antenna cable or module, which one is better to try first? I don't want to buy the wrong one.

Is it more likely this: iPhone 6 Top Left Antenna

or this: iPhone 6 Logic Board Antenna Flex Cable

Thanks!

Replace the antenna flex cable that has four connectors to the logic board compatible with the iPhone 6 model A1549, A1586, A1589 smartphone. Image

Not sure why @tomchai said none of those because replacing this:

iPhone 6 Logic Board Antenna Flex Cable

should certainly fix the problem. Everytime a customer comes with wifi being weak and all on my own phones for re-sale I replace the antenna in the top left corner (under the logic board) and wifi range is back to normal.

None of those.

First you have to tell us if the wifi is 2.4G or 5G, they use different antennas.

How can I look this up?

by

Someone on the Apple forums said that changing his router from 2.4Ghz to 5Ghz did the trick. I will try this.

by

2.4ghz is better for long range, but it's worth a shot

by

Also understand many devices are not 5ghz compatible, so this may not be the best long term fix.

by

My iPhone 6 is working on 5ghz but it's not long range. I have replace 4 hole antenna (gps+wifi). But still the same. 2.4ghz WiFi is not working good it is very weak.

I have replaced the F Cable antenna and it does the job, Wifi is running at full strength.

You can buy from eBay for cheap just for $2-3 only. Does not have any quality issue.

Great, I will try this.

One thing more, scratch the holes of the screws, the edge of the holes in the metal housing, where the head of the screw sit.

by

The screws at the bottom of the phone? What does scratching the holes do?

by

It works for me too

I know this doesn't really answer your question, but is the phone still under warranty? I would try to get a new phone under warranty before replacing any parts with your own coin.

Basically if your wifi is greyed out then it's a problem with your wifi module on the board. If the signal is weak its either an antenna issue or a software issue....or a communication problem with your router.

It does it with any router, including one I use my 6+ on constantly on same bandwidth at my house.

by

So it's most likely one of two things. Either the antenna connected to the board or your housing, if bent , could be causing a weak signal. I'd first try the wifi signal antenna...much easier and less expensive, then possibly a new back metal housing.

I corrected this problem recently. The first repair shop replaced the customers damaged chassis with a used one. This is when the 2.4GHz signal evaporated just as described. After I got the device history, I replaced the chassis with a nice straight one and that corrected the 2.4GHz signal problem. If you're 5GHz signal is strong, it's not likely to be the F-cable. You can further narrow it down by testing GPS and BT which use the same antenna. If they both work well, it's probably a bent chassis.

Flexing the frame brought the wifi back for me too.

I applied pressure with my thumbs one on corner by wifi icon and other thumb diagonal corner.

I supported other corners in the back with my fingers.

Hold the phone like you watching a movie:)

It works!!!!! Yeah !!!

my phone have inaccurate gps location and weak signal. First I replaced the wifi antenna (quite easy), only GPS function improved. Then I replaced the F antenna cable which connecting the antenna to the logicboard (you have to take the logic board out to replace it). Then both GPS and wifi work at full range. Good luck

I tried to do this, but it did not work anyway

My problem is

2.4GHz Wifi - does not work - weak signal - need to stay near the router

5GHz Wifi - works perfectly - full signal - even away from the router

Bluetooth - does not work

How do I find out if my wifi router is 2.4GHz or 5GHz ??

I dropped my phone and it started having this problem on both my work and home networks, so I knew it was probably not the router.

After reading David Rowe's response above I flexed the phone in a few different ways and the signal popped right back to full strength!

Worth a try...

I had this problem too, and I was trying all of these complicated solutions I was finding on the internet. In the end l, however, it ended up being my new phone case blocking signals on my phone. Take off your phone case and see if it makes any difference.
