I think this might be the router's problem ..

I have a LinkSys AP router, i can find it but i could never access internet no matter what i set .. WEP or WAP or no password ..

But i can use my WiFi in Big Apple or Starbucks .. weird eh?

i dont know bout u guys..
mine already updated to 2.2.1,JB..wireless works like charm..
and connected even faster than before..i've already connect my iphone to several wifi spots..
office,starbucks,my home,my fren's home,my cousin's home..
all works..

strange mine just hangs the phone. Nothing works at all unless I off the wifi and then it is back to normal. 

Was thinking of restoring it back to original and send it back to Maxis. I will restore it back to factory setting and see if it works. If it still hangs I am going to send it to Maxis. Wonder if they will do a one to one exchange.

Hello all,

My wifi problem started few days ago and till today its still the same, I have problem connecting to ANY wifi networks, home or outside, secured or unsecured, it just shows 'N/A' status at Bosspref. I never experience this problem before since Jan 09 when I got this phone.

My wife and myself each got an iphone 3G and her iphone got no problem detecting and connecting to wifi networks, while mine can't even detect, let alone connect. My laptop is able to connect to the wifi network and I can conclude that the problem comes from my own iphone.

I have done reset network settings, turn phone off and on and it does not help. I dare not restore my phone now as my phone is yellowsn0w unlock and worry after restore my wifi problem still persist I will have no chance to use my phone again.

I have done many hours of online research for answers but can never get any sure solution to resolve my wifi problem?

Do you think its the most feared wifi hardware failure?

Appreciate some help here.

Thanks

I worry after restoring it, if my wifi problem still persist, then i am unable to download yellowsn0w, then my phone will be even useless, losing wifi ability now is better than losing the use of phone in my opinion.

Having researched on the net, many people are having serious wifi problems and I don't think there is a sure way to solve it unless returning it for a 1 to 1 exchange, for me, this is not an option my phone came from aussie.

I am basically out of options now,

Hi Guys... I want to share my problem with u guys...

iPhone Generation : Iphone 3g, 16G , about 10 months in age
Unlocked? (or Part Number): Singtel Set, MB496ZA ( I bought the phone from someone, in lowyat.net)
Current Firmware : 2.2.1
iTunes Version : 8.1.1
PC/MAC : PC
Jailbreaking software : Not Jailbroken yet

Problem Encountered :

My problem started two days ago, whereby my iphone refused to connect to the net. When i switched on my wifi, the signal appears, then when I want to surf, it says, it is not connected to the net. I tried with edge, and it has no problem as compared to my wifi. I am currently using wifi in my college, and it doesnt need any WEP settings, or specific password or whatsoever. Previously, I was happily using the college wifi without any problem..

Steps Taken So Far :

I had tried soft reset it,  hard reset it and reset all network settings prior to this. Initially, the phone still can detect wifi signal, but it still failed upon surfing the net. After one network setting reset, the wifi it suddenly switch back to my edge when surfing. Then I reset all network settings again, and suddenly to my worst fear, the wifi has became GREYED OUT.. I resort to restore my phone back to previous backup, no improvement.. And last but not least, I tried restoring back to factory settings, but the wifi still become greyed out...

Through my reading in this forum and other sites, the only possible solution is the one to one exchange. My iphone expires on 22 August 09 (about 2 months from now) from the apple site. The age of the phone is about 10 months now..But i dun have any official receipt because when I bought it 4 months back, the seller didnt provide any receipt.

Now, in the state of despair, I am asking for opinions. Can I do one to one exchange WITHOUT the official receipt? Have anyone ever done it? Ive tried contacting my seller, but still no reply. How is the procedure exactly? I have browsed the forum, but i didnt get the ways to do one to one exchange without the receipt right. Right now, I am waiting for my seller reply, but if no response, I am willing to travel to singapore to do it myself or to give some incentives for whoever (that is trustworthy) to do this one to one exchange..

assuming it's a Singtel unit you own there (based on the blded part), there are chances that Singtel will honour a warranty exchange without the official receipt as few members did and claimed that they are able to obtain warranty without receipt. do approach your seller for clarification anyway.

The only time when I had problem with WIFI was the SSID issue. This when you first connect to an access point let say 'ABC'. Then you decided to protect this access point by giving it a WPA2 key or you change the attributes of this access point. Bang! iPhone can't detect any 'ABC' access point or it won't connect to it.

The steps I did was to restore access point back to normal then iPhone can connect. Then on the iPhone, I press 'Forget Network' so it would disengage. Do the necessary settings on access point and let iPhone rediscover the access point.

Sometimes I have to change the SSID name to something else so it can connect. Then press Forget Network and then change the SSID back to something I want before letting iPhone rediscover. Very sticky problem.

the same problem occurs to me as well. whenever i change the passkey of a particular wireless access point, the iPhone just won't connect to it even if i typed in the correct new key. so my solution to this is to "reset all network settings". (sometimes even "forget network" won't work).

After i update my phone to 3.0, the iphone magically can use the wifi again... I was about to inquire about warranty exchange that time... It is weird though, but deep inside I felt relieved that my wifi is back... Anyone has any thoughts on this?
