iPhone 3G / Wifi problem / 4.2.1

Same problem here with iPhone 3Gs.
I tried resetting network settings, resetting the router, resetting the iPhone …
Nothing did work.

Unfortunately I can’t set the MTU of my router. But it seems to be a iOS-problem so, Apple has to fix it!

Same problem here. I see the two WiFi APs in my home, connect to them fine and obtain all the correct IP address, DNS and gateway information, but cannot get any application to connect to the net.

I reset my router, my wireless gateway, double reset my 3GS and still no luck. It obtains and IP address, but goes nowhere!

Come'on Apple, get it right will ya!

Same problem hee I was hoping 4.2 would fix my iPhone 3G wifi problems.

Done everything - come on Apply lets get wifi fixed for 4.2 on the iPhone 3G !

I can buy stuff on the store so you are loosing revenues too !

getting the same problem with my wnr2000 netgear router. I hope apple are listening as this needs addressing. I hate to think what my vodafone bill is going to look like i only noticed this today

i am having the same problem. I installed the new iOS on tuesday and did not really mess with my phone till the next day when i noticed the wifi problem. at first i thought it was my router so i restarted it and my phone connected. then later that day i was at my friends house and could not get wifi there at all. when i got back home once again i could not get wifi on my router so i restarted it again but this time it did not work. since then i have not be able to get my phone to find a wifi network much less join one.
i have tried resetting the network setting on the iphone an went as far to suffer though the 2 1/2 hour restore process and still nothing works.
other than the wifi issue there has been no other problems with the ios... yet.

Boo apple for releasing an ios update that kills wifi on your devises. Do you even test your software before you release it?

Same problem with 4.2.1 on my 3GS iPhone and iPad. I changed the dynamic settings to static IP under settings and this gave me Internet connectivity. But this clearly can't be a long term solution.

I've tried everything to solve: reset settings, restore, pray but there is no way to make wifi working.

Apple, please, we need a solution!!!

If I can suggest that you dot point the steps you took and the order in which you took them so that someone is able to help you resolve the issue. Problem solving is simply a process of eliminating the possible issues. If no one knows exactly what you have eliminated in the process it is quite difficult to help you try and resolve the matter.

Start the download process..
Then..
Then..
Then..
Then..

the other option make an appointment with a Genius and have them connect the device to their WiFi network at least that will eliminate the device.

Ant..

I have the same problem. After install 4.2.1, my iPhone 3G shows in grey -without possibilities of selection - the WIFI option. Tethering has dissapared too.
Apple, Steeve Jobs, whats the matter?

Hi, I'm having intermittent wifi disconnections on both my iPad & iphone4 since the 4.2 upgrade. My network at home, where I broadcast the name, disconnects & is always visible but won't reconnect unless I reboot the device. I've tried forgetting the network & reseting network settings too. At work, where the network name is not broadcast, it's even worse, requiring a hard reset of my device & several attempts to reconnect each time the device goes to sleep. Many times on both networks my devices see the network, ask for a password but then refuse to connect. This is clearly an iOS issue.

I have a iPhone 3G and 4 and an iPad 'delivered in Australia' all have been upgraded to 4.2.1 without any WiFi issues. If you want to eliminate the device as the point of failure go to an Apple Store and have a Genius look into your issue. If you are not near an Apple Store then many Big Mac stores have 'Free' WiFi connections. If you cannot connect at either of those locations then I might be swayed to think that you have a hardware issue. You appear not to have commented on how you have eliminated your router as the issue..

I have exactly the same problem and it makes me feel crazy! I have restored many times, and only saw my Wifi one time. Unfortunately, after 5 minutes, it disapeared, so I decided to restore again, but I've never seen my Wifi network again.

Exactly the same for me on my 3GS after upgrading to 4.2.1

No more Wifi available !!!

I can connect within the option menu but no Wifi sign in the tool bar and no connexion.

I hope Apple will soon give some explanation about this blocking issue...

i have iphone 3g MB model. I tried freezer technique, reset network settings and still no wifi. It keeps circling and doesn't scan for any network and if it do manages to find my wireless network it wont connect. Is it hardware problem or software problem? Does anyone have a proper solution for this?

Please help

thanks,
