Wifi problems

I've had no wi-fi problems.

Try resetting the network settings on your iPhone. Go to Settings > General > Reset and select Reset Network Settings. This will erase all wi-fi network settings from your iPhone.

This will require re-joining your wi-fi network along with re-entering the password as when your connected to your wireless network for the first time.

I've been having the same issue, sometimes it connects, sometimes it doesn't. Very buggy. I have tried everything, i am on wep only router, it's an old router but my 3GS never had a problem with it.
I can connect most of the times, but sometimes it won't, i'll usually have to reset the router or change the channel for it to hook-up, very frustrating.
I hear it's a driver issue

Me too. Really really annoying.

Its got to the point where I don't even have wifi switched on in my home any more, I'm using the 3G connection, as it means less faffing around switching wifi off, on, try again, off on, switch phone off, etc etc..

BORING!!!!!!

FFS, can't anything just work as its supposed to these days?

Is this a problem with your wi-fi network at home only, or with any other wi-fi network you connect your iPhone with?

What troubleshooting steps with your iPhone have you tried?

Using WEP or WPA with your router?

Have you checked if you are running the current firmware version for your wireless router model?

If no change after resetting network settings on your iPhone and after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, more than likely this means there is a hardware problem with your iPhone - with the wireless card or something else. If you can't connect with any other wi-fi networks, this would be another confirmation of a hardware problem with your iPhone.

Take it to Apple and ask them to trouble shoot it.

There is something wrong with the wifi on the iphone 4. I was at a restaurant where they offer free wifi. I had been there before and connected to their wifi before with my old iphone. I noticed that I could not connect after getting my iphone 4 and it would not connect even though I see it on the list and selected it. The menu bar still say 3g. I took out my old iphone that I gave to my son to use essentially as a ipod touch, it connected without hesitation. The iphone 4 also had issue at a McDonald's trying to connect to their attwifi setup. This problem is not uniform. For example, I can connect at home and at work without issues. I don't know what the problems is, but I hope Apple can fix it on a software update.

There is something wrong with the wi-fi on your iPhone 4.

I've had no problem connecting to the free wi-fi network available at a restaurant I frequent often with my iPhone 4.

Did you transfer the backup for your old iPhone to your iPhone 4, or did you set up your iPhone 4 as a new iPhone the first time you connected the iPhone 4 to iTunes on your computer after being activated?

I have had this only a couple of times and turning WiFi off and on and reselecting worked. I have noticed if the public WiFi has a login page sometimes it won't pop up immediately and then you can't seem to get the coign page back.

I'm also have a wifi problem. My wifi has worked at home for the two days I've had it at home. I left yesterday evening for the first time with the phone (into 3G land 🙂 ). Ever since I've been back home, my phone has said 3G. I went into my settings to try to see if my home network will even come up. It won't. I tried to enter it manually and it won't even recognize it now even when I'm sitting right next to the router. My laptops are working just fine so I KNOW it's just a phone problem. This is very frustrating. I don't even know where to begin to address this as it WAS working and now is not??

If no change after turning wi-fi access off and on and after powering your iPhone off and on and/or an iPhone reset, on your iPhone, go to Settings > General > Reset and select Reset Network Settings. This will erase all wi-fi network settings from your iPhone.

If your wi-fi network still doesn't appear to select, try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup.

If no change after this, your iPhone has a hardware failure with the wireless card or with something else.
