Hi there, I am having a "the light are on but noone is home" issue with my Samsung galaxy SII:
At home, in my apartment, my phone can connect to my router in 2 ways. First I can deactivate "static IP" and it has no problem connecting, secondly I can activate static IP and simply type in the following information:
I do not type anything into the DNS areas, If I do then I cannot connect at home. However at work no matter what I do I cannot connect. I can get "connected" to the wireless by activating static IP and typing:
I can acctually type pretty much anything as long as all feilds are filled out with the appropriate amount of numbers. But even though I get connected to the wireless I do not have connection to the internet. I am a consultant where I work so I cant really go around telling them to restart routers or all this nonsense just so i can use my phone. So I was wondering if there was anything anyone would recommend me doing? If I cant use the wireless internet then so be it, just annoying to have a "smart" phone that isn´t very smart.
All my patients Iphones can connect while they are in my office, but my samsung can´t...
following this advice (from another forum for another phone):
Scroll down to the ‘IP settings’ drop down and switch it from DHCP to Static
In the ‘IP address’ box enter the same IP address which is shown higher up the same form
In the ‘Gateway’ box you will need to put the IP address of your router, to find this out I opened a command prompt window on a PC on the same network and typed ipconfig this will give you a Default gateway address which is what you need
In the the ‘Network prefix length’ box put 24 (this assumes the subnet mask from ipconfig is 255.255.255.0)
Finally in the ‘DNS 1′ box put the same IP you put in the Gateway box
Following these instruction I enter the numbers that I got, being:
And I can again, connect to the wireless network but still without any internet connection. I did also try various variations of those numbers, with and without the DNS inserted etc and nothing has worked.
I will keep this post updated with different solution that i attempt, for anyone who has a similar problem.
So I did as you said, removed all the wifi connection by "forgetting" them, reset everything to default setting without static IP, rebooted the phone and now I just hangs in "Obtaining IP address from <network name>"
As I stated in the original post, I am a consultant working in a large building I dont have access to the router information at work, at home I have no problems connecting. I cannot do anything with the router from work, unless it can be done from my PC.
Any other suggestions?

I have no idea, All I know is that I have access to a wireless connection in the building and the secretary gave me the password to connect to it. I get this same problem alot of other places though. My other job same thing happens, on the train same thing. I connect to the wireless but I cannot get internet access at all.
This happens to me every once in a while (I have separate DSL Modem netgearDG834 + rounter DIR-655) and it is usually the DSL modem not the phone or any other device which is connected that has the problem. It looses track of the DNS server which is actually relayed from your ISP ie. even though windows sees DNS server as the primary PC IP address, if you go into the router settings the DNS server will have an address that corresponds to your ISP's server. Suggest you reboot the modem and router and verify all wired connections are working first. After that it may have something to do with the wireless channels the router is using that may need changing to a different one but this is usually automatic.
I was having an issue with my SGS2 running 2.3.4 connecting to my Linksys WRT160N running DD-WRT v24-sp2 (08/07/10) vpn-small firmware that use to not have a problem. In the wireless settings I had both Wireless Channel and Channel Width on Auto and the security was WEP. I would see the phone loop from scanning -> connecting -> obtaining IP -> disconnected -> (repeat and repeat). I set the Wireless Channel to 8, the channel width to 20 Mhz and the security to WPA2 (TKIP+AES) and it is now working.
The OP has already stated that he has no access to the router's setup, unfortunately.
It may be something fixable with a firmware update, but it could also be that the router is using the TKIP rather than the AES encryption algorithm. Trying to connect to my own router when it was set to use TKIP showed exactly the same symptom - handset would connect but not complete authentication and therefore not obtain a valid network address.
