wifi not staying connected

im going through the same thing right now. I was looking for an answer but havent found anything. Its like its dropping wifi to pick up edge when it should be the other way around. And this is only at work, my home wifi works fine. Plus it worked fine about a week ago. Let me know if you figure it out, and I'll keep this post updated as well.

 

I recognize this aswell.. do you guys also have 1.1.4? It wasn't like this before I updated. I have tried everything except going back to older versions - I've reset it, restored and the whole thing... -_-

 

I've been having a similar problem. So far rebooting the phone has worked to reconnect to wifi. I had been thinking it was because my phone (Day1 1.1.4) was jailbroken (ZiPhone). Those of you who have been having similar probs - is your phone stock or have you jailbroken it?

 

That happpened to me too. It's not my iPhone, it's my home broadband connection. I reset it and my iPhone works.

 

I had a very similar issue and I found that it was being caused by a cheap netgear wifi card in one of my computers. After removing that device from the network the iPhone wifi seemed to work great. All my other computers worked fine though for some reason the iPhone had a problem with it. Maybe this will help someone.

 

I have a similar problem with a jailbroken 2G phone. I had it with firmware 1.1.3 and now with 2.0. The wifi connection is unreliable, connecting and dropping off with no apparent reason, even when I'm sitting right next to the router. Sometimes it remains connected for 20 minutes, sometimes for 20 seconds. When I try to reconnect I often get the message, "Unable to join the network XXX". This happens both with airport express and another router in another part of the house, as well as with hotspots out in the real world. Incredibly frustrating! This seems to be a widespread problem. Can anyone offer possible solutions? Thnx!
