Chosen Solution

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.

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. F Cable Antenna

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.

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 !!!

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.

Did You Repair It? Im having The Same. Problem For Ages

I have the same problem. what can we do? Is there a solution?

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

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 replaced both parts i own an iphone 6, and after i replace both parts the phone started working just like new, i would recomend to try it, now both the wifi signal is super strong, and the gps is pinpoint accuracy, change both parts, you can find it cheaper on ebay

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.
