Sudden Weak WiFi signal on 3Gs

that's great news chris.

Anyway i hope i have helped you guys. That's why forums exist to help each other 😉

Hello Rocky,

i bought it from a website in Cyprus which is located in Limassol (town in cyprus)

I bought it for €15 and the website says that the deliver worldwide.

If you want the site, reply to me.

But on ebay you can find it much cheaper.

Hi, Just wanted to add some input on what worked for me when my iphone started experiencing loss of wifi connection.

My 3gs wasnt picking up any connection at all even when standing right next to the router. I started tinkering around with some settings. I turned the "Airplane Mode" slider to ON and then back OFF again and suddenly my wifi started working again. I have no idea why or how this worked but just thought I'd share what worked for me.

I cured my 3gs "battery munching" problem - but the wifi only works when right next to my router. I have another 3gs the same on 5.0.1 that works fine - picks up my wifi and the neighbours no probs. I have replaced the antenna in the phone - done resets / udf resets turned on and off various things - same wifi issue! The bluetooth is working fine but makes no difference to poor wifi if BT is on or off. Connection in phone is OK. I can't revert to earlier software as I have no saved blobs (****!) ......... any other ideas guys?

Hi All,

Some of you may still have this issue, so please see what I have found out minutes ago.

I also had the same Wifi problems for weeks and was just about to believe that the only solution is to buy a new antenna...well, it might solve the problem (and I am sure it does) however there is an other solution which you should try before making any investments on apple products or accessories.

In the past couple of weeks I've tried everything, read all forums, changed settings, reset then restored my iphone 3GS and nothing happened.

Today, all I did was removing the sim card. I stung a paperclip into that little hole and took the sim out, switched the phone off, put the thing back in and restarted the phone and tadamm: Le iphone 3GS has stronger Wifi sign then ever...(at least much stronger than it had in the past few weeks).

I think in case you exchange your antennas, you also do these basic steps, as you need to remove your SIM card before you open the phone.

Try this out, it is simple, but after 4 weeks of struggling with a useless phone, I have Wifi again after just a simple action....:-)

And now an official letter to whom it may concern at Apple:

Dear Apple, it's time for you to send me my I-phone repair expert certificate together with an offer letter, since it is not the first time your so called experts cannot do anything and I have fixed this sh*t on my own. And I am a woman. Not an engineer.

Did everyone find a solution to the issue yet?

I've just tried removing and re-inserting the sim card, but that had no effect. Will check connector 6 tonight and if that doesn't work will get a new antenna and try that.

I'm running iOS 5.0 (9A334) with modem firmware (baseband) 05.11.07 which is the original baseband on iOS 3.1.2, so can catagorically say that this is not a firmware issue. It's either software (driver) or hardware (which somehow could have been caused by the software, given the number of people that this has happened to).

I didn't start getting problems until upgrading to iOS 5, which were mainly GPS based, but over the last couple of weeks my wifi has gone from intermittent to useless. Shame, as everything else is better under iOS 5 that ever was when using iOS 4.

--UPDATE--

I have checked connector 6 and it was firmly attached. I disconnected it, blew away any dust and re-connected it. I seemed to have better WiFi briefly but it was very shortly back to how it was before.

I stumbled across this http://www.snackyserve.com/iphone_3g_wifi_fixed/index.html which suggests that the problem is related to overheating and gradual de-fluxing of the WiFi IC. I can believe that, it seems like a plausable reason to me.

I'm going to try the antenna replacement first as I don't really want to screw up my logic board, however I may give this a go when I get my iPhone 5 (in June/July please Apple)

Nice find. I didn't know that dust can still get inside in this area.

Hey eagle,

The only solution is to change the wifi antenna. Don't puzzle your head and i am telling this to anybody in this discussion, just replace the wifi antenna.

don't be afraid to open your iphone. There are a lot of "how to" tutorials in youtube or ifixit.com

My iphone (when i purchased it) had a cost of around 650 euros. 10-15 euros after 3 years to repair my iphone is nothing. But now i have my precious back again for another 3 years (i guess).

Yep, changing the WiFi antenna did it for me. My iPhone's back to normal for only £4.99 (UK people google parts4ipods), brilliant 😁 I did notice that the new antenna had a more positive click when connecting it to the logic board too. Hopefully I'll also see improvements in my GPS too now.

There was a ton of dust in my phone, my guess it creeps in through the silent/loud switch, as it looks pretty open around it and there was more dust in that area of the phone. That switch certainly works better now I've cleaned it out too.

For the record, I smacked the back of the phone into my hand, and that fixed the problem - and got an interesting stare from my wife. I guess that's technology for ya. At nearly 4 years old, I'm not going to buy new parts if I can help it. If this thing can hang on until they release the next iPhone, I'm gonna wait it out.

Good luck everyone!

To all u guys out the witnh iphone problems in more ways than one, i was a iphone avocate from the very first one all the way up to iphone 4, and even with all the headaches with software problems and updates, and that rediculous itunes i loved my iphone, But like every other person i eventually got fed up and started looking elseware for my phone needs and to my supprise while iphone is still the best (for now) the rest of the world is catching up,i did alot of research and comparing before i made a decision and bought a Widows 7.5 mango, phone from HTC and never looked back, i absolutely love it, i t gives me everything i need without even a hicup, sure they dont have hundreads of thousands of apps, but how many apps can u really use on a phone, pc comnection is great, sky drive is simple and user friendly, not to mention u get more gbs of free space and cheaper rates than the icloud, all i'm saying is take a look around, theres alot out there to meet everyone's needs that does'nt have and apple sticker on it, apple's prices are getting rediculous, service and support is lousy and and there software arn't as reliable as it used to be, sorry to say but i've had enough, cause its always something.

I had this problem since two days ago, today i read somewhere you have to give it a good smack in the palm of the hand, tried that and it worked for me! at least for the time being...
