Strange WiFi problem on iPhone 3G after 3.0 update

hi

as reported previously, they offered me nothing when i booked an appointment at the genius bar at my local store, as it's out of warranty they've said there's absolutely nothing they can do and suggested i wait for a new update...which may...or equally, may not, fix the issue, oh and that's an update that they don't have a release date on too. so from the day 3.0 was released i've been with out wifi and will continue to be so until a magic fix materialises at some point...that no one knows when (although estimated september sometime)... so the problem that, conincedently was introduced after an offical software update from apple. no 'dodgy' software installation attempts. every possible thing 'above board'. all i am 'guilty' of is connecting my phone to my computer to sync, seeing an update was available for the handset, and agreeing to update. really put out with the response i got. i fully appreciate it wasn't the employees fault as such, but to walk away with the answer that basically i have to 'suck it n see' indefinately wasn't the most confidence boosting.

still really frustrated by this. struggling not to loose it with someone...really am...
😟

I tryed 2 of the 3 step of yonido (downgrade baseband and drain battery completely). In my case (iPhone V1), the first time I tryed to downgrade baseband (04.05.04_G to 04.04.05_G) AND firmware (3.0 to ... 1.1.4 !), the Wifi came back ! I try after to keep this baseband with a 3.0 firmware but it makes my iPhone crash. I try a lot of combinaison (2.0, 2.0.2, 2.2, 2.2.1 firmware with baseband 04.04.05_G) but no Wifi. The second time I tryed the same operation, I had Wifi signals but no connection.

The battery test did not give me the wifi back.

I don't know how to think about this issue ...

Well I took my phone to the Genius Bar and he reset my network settings. Seems to be working ok now, but he said if I had any more problems to let him know & he'd replace my phone. Fingers crossed!

Very Genius man, at the Genius bar ! I reset my network settings many and many time and it never works for me ... But I know other iphone users who try this and wifi works for them. Lucky guys !

OK, now I am on my third iPhone - all replaced in the warranty period. All my iPhones worked great with 2.x software.

Now I am on 2.2.1 and I AM AFRAID to upgrade to 3.x again. Now it works perfectly with 2.2.1, no trouble at all. WiFi stable everywhere - even for hours.

However, as Apple decided not to tell us is it a software or a hardware problem I have doubt what to do next month! My warranty expires on September 3th!

If it's only a software baseband problem, then it should fine with 3.1 once it's out, right?

If it's a hardware problem that shows only with 3.0 update - I should update and kill it again, right? And to try my luck with 4th iPhone?

The problem is that we don't have Apple Stores here and so we must wait for weeks for a replacement iPhone... 😟

What would you do?

Well my issue is that its not detecting any networks after working fine for a few days WITH the 3.0 software. I've been scavenging around forums but don't have a solution yet...anyone else?

Davor, I've now got my 4th iPhone after Wifi issues. I called up my service provider (o2) and told them that I wanted to cancel the contract as they weren't providing the service that they should've been. After a chat, I was eventually offered a replacement phone, seeing as this was my 3rd iPhone, and asked for a 16gb 3GS. I got it, but, and this is the only but, I had to start a new contract for 24months, which I'm not too bothered about.

Received the 3GS and all working fine (been a day so far)

As far as I'm concerned, if this wifi happens again, then I will be cancelling the contract and not paying anything to get out of it because as far as I'm concerned, if you can't use the services through no fault of your own, then what are you to do, warranty or not!

ok Dam2-7Tem you're the only one cooperating here, thanks!

Would LOVE to hear more details:
- what was your exact wifi problem? 'no wifi' (gray in options), weak signal, or it just didnt find networks?
- after u re-installed 3.0 wifi was gone again?
- did u ever try the freezer test? what happened?

Hi,

I have OS 3.0, had the same problems everyone was discussing, tried "Forgetting this network" then rejoining and it solved my problem perfectly!! Thanks.

dam27 - i saw your reply, and after a while it disappeared. i hoped you're the one deciding to remove it and not some mod here...

anyway - as for your results it seems more like a hardware problem to me, because the first time the downgrade worked and the second it didnt.

plus - you have an old gen iPhone, and a negative freezer test so i dunno how much you're like 'us' 🙂

I did not decide to remove my post ... It's a mod operation.

No, I don't think it's hardware failure because I can see Networks sometimes, for few minutes. But I can't connect. It is possible that the 3.0 firmware decrease the sensibility of the Wifi to increase battery life ... So, I wait for the 3.1 update ... Wait and see ...

i remember your post very clearly. there was nothing there that justifies a removal

weird

Yonido : Send me a mail : dmauran AT gmail DOT com ... Modo removed my post and I don't like this. I will not come back here.

I was one of the lucky few that was able to get my iPhone 3GS on wifi shortly after resetting it... I just set my base station to a manual channel... Then recently I upgraded to 3.0.1 and it showed it was connected to my network, but the actual wifi logo was greyed out with no Internet... So I reset my network settings and I've been back online ever since... Now my issue is with the battery... It drains really fast, down to about 30%, then it all of a sudden jumps back up to 60%... Very weird. A fix really soon would be nice! I couldn't imagine it without wifi though!

I have the same problem with wifi. Initially after 3.0 update everything worked perfectly, but recently I noticed this annoying bug that once I start downloading something using wifi network, iphone drops the connection. Once I pause the download, wifi signal is back to normal.
Today in the hope of getting this bug fixed I upgraded my iphone to 3.0.1. However, to my pity, it didn't solve the issue.
Btw, I followed Apple instructions and tried to reset the network connections, alas it didnt help either.
I just hope Apple will soon do/suggest something more helpful about this issue.
