WiFi - Connected but not working - Page 14 - iPhone 3G

sartoric · 08-21-2008, 04:35 PM

My Wifi works great at home - at work it says I have a signal - I am right next to a wifi box - yet nothing works? Cannot send/receive email; Pandora is choppy at best.

I work on a large university campus and I know the signal is strong - why can't I use the Wifi??

If the WiFi is security enabled, you may not be able to connect without either providing a key, or having an approved MAC. I had problems with my V1 iPhone and my Netgear wireless router when I tried keeping my SSID hidden and having to use security encryption. After keeping the SSID visible, but filtering by MAC address, I've had no problems since.

Keep in mind as well, that some WiFi connections such as that at hotels, require you to "sign in" before you can use the connection for data traffic.

I can't get WiFi to show up on the phone. I used the Pwnage tool to unlock and jailbreak the phone with 2.1. I go into setting and it says no Wi-Fi. I can't even go into Wi-Fi settings. Any idea of why this is happening?

im having same probs but that did not fix it, I made a new topic!

Here's a question : Is a connection to your mobile service provider (i.e O2 in UK) a necessity when trying to connect to the internet wirelessly?

Cesto · 10-05-2008, 09:53 PM

Yeah, its going through 02 UK and trying to connect to 3G or Edge, even though im connected to wireless WIFI at home. Im not too sure how to fix this, and the closest apple shop is in london that over an hour away

Here's how to fix that issue. First run cmd on your desktop machine where the internet connection is coming from. Type ipconfig/all then hit enter. Note the DNS number that will come up (There are going to be many other numbers, you just need the DNS).

1- I have the iPhone connect to the wifi using default DHCP query.
2- After that, change the wifi setting in the iPhone to use the Static mode (DHCP, BootP, and Static modes for each wifi connection)
3-Then fix the DNS address to the DNS address we obtained before.

The problem is solved.

My router: NETGEAR WPN824
iPHONE : 8GB
Wireless security : WEP
Authentication type : Auto
Encryption strnegth : 64bits
Key : 1
Network Channel : 6
Mode : 108mbps

First i reset all the network setup in the iPhone. Then i set the router up with NO wireless security. Without security, the iPhone connects inmediatlly to my network. On the iphone i went to Settings-> Wi-fi and on my network setup and i verified that all the info under DCHP, BOOTP, STATIC were filled in, as they did, then i changed everything to MANUAL, so the information already there does not change after i change the wireless security back to WEP on my router, then i went to my router and set the wireless security as stated before. Then on the iPhone try to connect using the Key #1 as password and BINGO ! I am CONNECTED to my network and using my home internet connection as soon as i walk into my house. Good Luck to all

Thanks so much! A slightly modified version of this was the ONLY thing that solved my problem after many other attempts. Too bad it took so many hours to find it! Sadly, swtiching the wifi settings to manual didn't work for me.

My router was set up with: 128bit WEP-manual encryption, no MAC approval needed. I was never able to get the Hex/ascii security option so couldn't take that route. Resetting the router and the iphone, turning Wifi on and off, switching to airplane mode and back, inputting the DNS from my router settings, on and on... nothing worked.

Here's what did work: chose option to "forget this network" under iPhone's Settings>Wifi>my network; turned off Wifi; put iPhone to sleep; turned off the wireless security on the router and restarted it. Restarted iPhone; turned on Wifi; selected my network. After several seconds, the iPhone's network settings were completely and automatically assigned with correct IP address and correct Subnet Mask (now matching my router settings, unlike before), filled in router setting, and filled in DNS server address!! Next, I reset the security on my router to WPA-PSK and reset the router. When the iPhone asked for the password to connect to my network, I used the WPA-PSK Key I'd set on the router.

And, voila! Stable Wifi connection after HOURS and HOURS of angst and frustration. No defaulting back to Edge. Just stable, FAST Wifi connection to the internet! Now this is the iPhone I paid for!!
