Sometimes i have to manually connect 5-20 times my WLan in the settings screens before the connection is up and working, a second iPhone of my friend with 2.0 has the same problem.

With 1.1.4 there was no problem at all.

The chipsets of the WiFi access points are different (a AVM Fritz and a Belkin)

Any suggestions for this problem?

BTW: Both are fresh pwned iPhones with Cydia and Bossprefs to disable EDGE, mine has 2.0.1 (since yesterday, had the problem also under 2.0 and hoped 2.0.1 will solve that problem), his 2.0, both with BL4.6

I have had a similar problem connecting to my WiFi on various iPhone’s. I sometimes help people out with their iPhones, and because of this I see a lot of iPhone’s

I have two 1. Gen. iPhones running 2.0 and 2.0.1. Both these iPhone’s can connect to my router (Edimax BR 6504n, WPA-2) and have an IP assigned automatically. This is great so far.

My problem is that when i upgrade older iPhone’s (pre 2.0) to 2.0.1 they all have problems getting an IP assigned. If I enter the IP, gateway and DNS manually, they connect just fine. These iPhones that won't properly connect to my router connect just fine to my neighbor’s router, which has no password protection and they automatically get an IP assigned.

This is quite a conundrum. If anybody can shed some light on why this is, that two seemingly identical iPhone’s don't react the same way, I would be a happy camper

Is there maybe a way to the real error on the commandline in a terminal?
I've allready searched for this, but sometimes i can't find the right words to describe my problem

i have the same problems... cannot find out a soltion anywhere and its driving me mad!!!!

pleeease can someone help?

@Coward626 & Nuttynuuter123
what are your Accesspoint configured to? WPA or WPA2, TKIP or AES .. or just WEP64 or WEP128.

I know my Belkin is configured to accept connections in WPA / WPA2 TKIP & AES ... i will test if it's better when i just allow one encryption!

I have the same problem. I'm using WEP, and 5 times out of 10 my phone won't connect to the network. On another (open) network, I can connect everytime, but can never get an assigned IP. It's driving me nuts.

On a Russian iphone forum I saw people speculating about the Wi-Fi instability being due to skipping restore to stock 2.0.1 before DFU restoring to custom 2.0.1. They also have a guide there with that extra step (no English language guide has that step built in, btw). Reasoning it may hold some truth, I stopped off at stock 2.0.1 on my unpwned 1.1.4 before restoring to custom 2.0.1 I made. Went flawlessly, restored as a new phone in iTunes and can confirm EVERYTHING's working like a charm now (knock wood!) -- WiFi is as good as it was on 1.1.4! Youtube, Mail, Edge, Location, everything's 100% working! I'm not claiming that's the exact reason of all Wifi issues, but it never hurts to try... In your shoes, though, I'd do something with my baseband first (kiphone) because restoring to stock 2.0.1 will not reflash the baseband for those of you already on 2.0.1, so your WiFi won't be any better.

thats intresting. do you think it could be winpwn/pwnage hasnt flashed the baseband properly in some cases then? i never had the stock i went straight to a custome 2.0... that custom 2.0's baseband may have been a bit dodge you reckon?
whats the easiest was for me to lower my baseband and then reflash it to the latest one?

Use kiphone for downgrading your baseband, though I can't vouch for its reliability.. My last baseband downgrade was a VT-100 powered business back in 1.0.2/1.1.1 days... Again, there's no hard evidence that the WiFi issues are due to skipping the stock firmware, just pure speculation.. And if you think about it, the stock restore shouldn't even matter, as you have bootneuter popping up and reflashing your baseband over whatever you might have had there... But then again, who knows?....

Well I have to admit I did not think this through too much. Deciding that it made no sence that two almost identically iPhone acted differently!

I turned my eyes to the Acess point and the router. I reconfigured both of them, and now both old and newly upgraded iPhones can connect, and have an IP assigned automatically. I configured my acess point to use WPA preshared key only, the DHCP server runs from my router. Think I was a little unclear about my setup in my earlier post.

It seems that the problems I had were not similar to yours. I hope that you find a solution to them though
