iPhone forgets my Wifi Password

Same problem here. Irritating to have to keep re-entering the WEP. Worked fine without issue for 1.5 years.

Here is the generic Apple support on wi-fi issues:

There are some comments re WEP keys at the bottom.

I've seen that its when the WIFI Signal is in a strange or low level... Usually when I get the password box I will cancel it until I get closer...

Also I think that recently someone in my neighborhood has generated a WIFI station with the same name, therefore the iPhone looses the connection with my device and connects to thiers!

A good way to help ensure that this is not the case, is make sure that your Wireless router is named uniquely... Hope that helps...

Yes I am having this same problem. I have tried generic help on the above link, but did not help. I now have to reenter my password every 7-10 days. My user user experience has dropped because of this.

Have you tried a WPA password protection scheme? It's much more secure and I've NEVER had a problem with my IP 3G or my new IP 3G S remembering my WPA password.

Yup, almost 7 days exactly for me.

Excellent advice. My experience, too. I never have to re-enter my password, even on other networks I use once every couple of months.

I thought I would humor you and try your idea. Updated my Airport with WPA last night and this morning my iPhone had forgotten the password. What's strange is I was connected using the web and then instantly while surfing it forgot the password. I have 2 other computers constantly connected to my Airport, all indications point to the iPhone and the 3.0 update.

Not to bad. It only took 10 days to forget the WPA password.

Maybe if you use a shorter password, it will remember it longer. Works that way with my memory 😉

I have a Wifi network protected by a WEP key. Every now and then, the iPhone prompts me to enter the key - all works well for 24-48h then I get prompted to re-enter the key. Any fixes to ensure it is not forgotten?

I too have been experiencing this exact same problem. However, for me, it did not just recently start happening...it goes back at least 9 months, shortly after I got the phone in Aug '08. And yes, this is very, very annoying!

Also, I cannot change from using WEP for router security at this point. I have too many other devices configured to use it and they cannot change. Those devices do not have any problems connecting to the network.

I have the same problem. The network used to remain above 'Other' but now disappears every time.

I'm using a Belkin 54g, WPA, with SSID hidden. Still works fine with PowerBook, iBook, and Apple TV.

This has been happening for about a week, perhaps since 3.1 (not an option in OS below!).

One thing that might have a bearing. Someone on an iPhone forum said they couldn't see how to enter a WEP or WPA password. In order to describe the steps, I needed to force mine to prompt for the password so I used the 'Forget' option. It's as if I can't make it "unforget"!

I think I might have an answer, found here.

Go to Settings > General > Network > Cellular Data Network and note any changes you've made to the default settings. For me it was just the APN (3 instances).

Then Settings > General > Reset (right at the bottom) > Reset Network Settings. You are prompted for your passcode then there's a confirmation button.

I had to reinstate my APN settings, as expected. I've reconnected to my wifi and *so far* it's not forgetting it. 😀

I have the same problem too.
I will try the suggesting the last post here,
Really hope it helps.
This is really annoying.

It's been over 2 days and the phone is still remembering my network.
