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!

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?

による

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

による

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

による

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

による

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.

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.

による

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

による

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.

による

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.

On a iPhone 6 that has a weak 2.4ghz wifi signal and 5ghz works fine, also it has problems with gps. What would you think the problem is? Thx for the help!

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 !!!

i have the same problem. i cannot see 2.4ghz wireless networks. I changed many components including f tri chip on the 2.4ghz antenna line. still weak. my last resort is replacing the wifi chip. Any suggestions would be appriciated. i also check up top near the standoff screw where small silver antenna connect to phone frame. all inductors and caps have been replaced including f tri chip.

5ghz works perfectly I'm happy. So this is not a hardware issue a software glitch because the 5ghz is working like a charm with full range better than my android unlike 2.4ghz

Not yet, but I'm going to try what David F and sasha recommended.

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 ??

による

コメントを追加

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'm so proud, I have to brag to someone! Hopefully I can help someone too. First, my backgroun: I'm a 49-year-old mom. I drive a Subaru station wagon, for God's sake. I have no tech background, but do admit to a DIY gene I got from my dad.

Anyway, both of my kids' iPhone 6 phones started getting little to no wifi connection. They could maybe get three bars directly next to the router, but as soon as they moved away, they'd lose it. I bought a GPS Antenna Signal Flex Cable Ribbon Replacement Part for IPhone 6 (4.7'') for $4.90 (actually, I bought two, hoping to fix both phones...glad I did, because one came defective and I didn't look to find out until I had the phone completely open and dissected. Maybe order two, since they're cheap, just in case) and a $7.99 tool kit off Amazon, and fixed it!! I followed two different youtube videos, but ultimately only needed this one...there are a bunch, though. The phone works perfectly with a strong-as-new wifi connection!

Notes:

1) The first video I used ended after removing what the instructions called "wifi receiver" and I thought, "F*&K!" thinking I had ordered the wrong part. But the second video went on to remove that part, calling it the "cover" and the "mother board" to reveal and replace the antenna, which looks sort of like an "F." This is the only part I replaced and it worked to restore the wifi signal completely.

2) There are roughly one million screws ;) to remove, and they're minuscule. I drew pictures (using #s to track the order in which I removed the parts, and labels) and also took pictures and used the "mark up" editing tool on my phone to make notes. It wasn't pretty, but there's no way I would have been able to put the phone back together had I not done that. The hardest part was removing two stripped screws...I found a youtube video with hints for how to remove those too...finally I did it with a combo of the tools I bought and tweezers (which the tool kit doesn't come with, and I recommend having). Altogether, I watched the videos on my iPad, used my phone to take pics, and used a pen and paper for notes and laying out screws by my labels. I also used a really bright bedside/task lamp, my reading glasses, and a glass of wine!

I think this is all of the hints I have. It's a little scary, and there are some connectors that are so tiny, it's amazing you can snap them back on (like the battery connector), but you just have to go for it. If your phone doesn't get wifi anyway, and you don't have unlimited data, I'd go for it! It took me two hours (would have been 1.5 if it weren't for the stripped screws). Good luck!

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.
