my S2 ICS was working fine with my home wireless until a few weeks ago now all i get is authenticating, optaining ip address common problem apparently. Allocating a static ip address to the phone i supposed to work. I don't know what's changed

Thanks for the information. I have exactly the same issue. I just did not understand whether a factory reset of the router alone has resolved the problem ? If so, why did you do the same with the phone ?
I am having the same problem. Just updated my SII to ICS and now, it takes ages to connect. The only way to quickly connect I have found, is to reset my router. Immediately after I reset my router, my SII connects immediately.
I have two home wifi routers. SE arc S upgraded to ICS 4.0.3 can't connect to one of them (which, as usual, I need more). Router resetting helps connection only ONCE. After breaking connection, it can't connect again. Any action on the phone doesn't help. I think I will downgrade to Gingerbread.
I upgraded my Galaxy Note with the new ICS firmware and also did experience wifi connection which took ages to connect or else says no connection. Then I read the threads on this forum and found that it is a problem with other users too.
So following one of the suggestions along the thread, I went to
then to the applications
then to my facebook
and cleared the cache.
and facebook connected easily and so did my internet explorer.
I THINK I HAVE THE SOLUTION. This same problem has been making me CRAZY for nearly 3 months, but I think I have solved the issue to Galaxy SII dropping wi-fi after updating to ICS. In my situation, there were some networks where the wi-fi stayed on and worked without any problem, but then there have been many (probably 60%) others where the wi-fi would consistently get dropped right after connecting or within 30-60 seconds and it wouldn't save the password. It had been playing well with my home network until I upgraded it about a month ago with completely new hardware and then it basically stopped working with my home network. I thought maybe it had something to do with ICS and certain kinds of hardware since it had been working fine on my home network before the upgrade. To some degree I guess this is true, but I think I have figured out the ROOT of the problem. Tonight, I was looking at my apps and read more closely what AT&T Smart Wi-fi app does. I UNINSTALLED it and my wi-fi has now been working for a few hours completely fine on my home network. I hope the same solution works for all of you. I suppose if you don't have AT&T Smart Wi-fi but some other similar app you should try uninstalling that instead. There may be some kind of setting within the app that would fix the problem, but I didn't try that. I just got rid of it.

hey guys , a few days back i wanted to connect my galaxy s2 to a new wifi network , and before doing so i deleted all the previous saved wifi networks and since then anytime i am turning on the wifi , the phone doesn't find any available network !! have you got any suggestion for me ??
1) You need to assign static IP to your device in the router settings (fixed host). Search for the router specific instructions online. You will need to enter phones MAC number and then assign ip. You can find MAC number settings>about phone>status>wifi mac address.
2) Not sure if necessary, but on you phone you need edit WIFI details for your router. In advanced settings for the router you need to change IP settings from DHCP to static.
Not sure why it works. Must be something related to dynamic IP in DHCP network.
