Hey there all, I installed os 4.0 on my 3GS and everything seems to be working fine except my WiFi. It askes for my password, I enter it and it says "Unable to join"?>????

2 Laptops, 2 iPads and my wife's iPhone are all on the wireless? I know the password is correct....

WTF????

It's almost as if it's a dev preview that's going to be prone to bugs and not a final golden master copy.

Strange that.

Try re-installing. Might help, if not, it's an early build, it's to be expected that it's not going to be 100% there otherwise we'd all have a lovely update waiting for us the next time we plugged our iPhones into iTunes.

Yes. WiFi is broken for me. 3GS, Linksys dual band router running dd-wrt. Fine with everything else including iPad. Was fine prior to 4.0. even with Setup as new phone and no restore.

I'm having the same problem. I can't login into my wifi network at all. But, it connects the the wifi network at my Mom's house without any problems.

Same issue here

I have a Linksys Plain vanilla Firmware WRT110 router setup with WPA2. Keep getting message "Unable to Join <SSID>"

Can't connect to my home network (Wireless N - DLink DIR655)
Can connect at work to our Cisco Wireless G Network.
Can't connect at work to out DLink Wireless N Network.

So maybe the problem as something to do with Wireless N (or DLink stuff ? ).


Both N networks have a b/g fallback

Found A solution to wifi issues.

Looks like the OS 4.0 has IPV6 set to automatic. Disabled this settting and changed the home wireless network from Mixed Mode to Wireless G only. Now the wifi seems to connect fine.

I didn't test this with Wireless N only as my router (Cisco WRT110) always seems to have problems in this mode.

I'm on a 3G phone and had wifi issues, I restored and then restored from backup and when I ran echofon and facebook even though I had a wifi signal full bars it kept saying my wifi had gone offline (which I knew it hadn't) but after a few tries I think it's working properly now

Where is this setting to change IPV6 to auto in the iPhone? Are you talking about the router?

Same Issue

Exact same thing happened to me after i upgraded my 3G to 4.0. At week or so later i upgraded to 4.0.1 thinking it might resolve the issue and at that point it got worse as it no longer even sees my wifi (or any wifi) SSID. I've searched on the web and seeing MANY other reports of this issue along with other problems. The only response that I have seen is that "Apple is investigating..." ... I really don't think that Apple is taking this seriously (or perhaps it part of a bigger plan???). I'll live this the problem until my cellular contract is up for renewal (~2 months). If it isn't resolved at that point my plan to move to another product ...

My ip4 has same issue on 4.0, it comes and goes. Sometimes it'll keep asking for my password, I enter it (correctly) still says it's wrong, or unable to join. Never had this on my 3GS pre 4.0. Must be a 4.0 thing.
