Cant obtain IP adress...please help. - Galaxy S II General

FINALY today i get my galaxy s2. now you will have my suportt guys
But i have a "problem"
My router is set to WPA/WPA2 PSK...when i enter my password it will not connect,just obtaining ip adress.
when i manualy put my mobile's MAC adress in router then its working,but its scaning every 5sec...
So can someone please say why i canot conect trough my password and why it keeps scaning after im allready conected(but only trough MAC adrees) tnx

You seem to be confusing a few terms, but it would appear you have MAC address filtering set up in your router. That's generally a false sense of security. It's normal for the wifi to be scanning even when connected.

ah so...i didnt know this. But altough im conected,i canot access internet...it must be something with my router...anyone knows?
i conect to my laptop normaly...

sometimes my router doesn't connect to my phone but does to my laptop as well, and sometimes visa versa, try rebooting router and devices. that usually works for me,

Wifi Problems On Cingular 8125

Hello to all
I have problems trying to connect through wifi on my new 8125.
After reading a lot of threads, i downloaded a program called hitchiker, who solves the wifi connection a lot easier and faster, but i keep getting the same error, the wifi connection appears, it connects but can not solve the ip address with the dhcp server and fails...
Can anyone told me if this is a hardware problem or a firmware issue?
my router is a netgear WG602 v2 with the last firmware available.
Thanks and happy new year to all!!
ddo you have mac filtering on? if so try turning it off
No, i used to have a wep security password, but i reset all settings on the router to factory, to try to connect.
i also have a laptop and a psp and both connect great!!
dont know what the problem is here, but its frustating...
I make it to work
first i did a hard reset, then i check on the log of the access point, and it was going through and forwarding the connection to the adsl router, but the problem apparently was on the dhcp server on the router.
i add a fixed ip, and now it works
still not working on dhcp but at least its working...

I'm having almost the same problem.
First I've tried to connect on my open lan in my house. I could connect, but couldn't get an IP automaticaly.
Today I went to the mall to try some open wifi lan. A friend of mine, with a Nokia n80 succsessfully connected with one of the hotspots. I've tried and couldn't get an IP. Suddenly, don't know why, I got connected, but couldn't surf at the web.
Then I realized that the fixed Ip that I've set before was still on. Changing it for dinamic didn't work.
So, I still can't get an IP.
Any Ideas?

Wifi but no Internet

Since I bought the HD2 before 2 month and after 2 Rom upgrade I still have the same Wifi problem. I can connect to my home network and the Router can see the HD2 but I can not connect to the Internet through the Wifi. All other computers and PS3 connect just fine. Ip adress seems also ok.
Please help ?
I did have the same problem a while back, and it occured after I used the wifi router. Have you ever used that, even just to try it?
No I never tried the Wifi Router even once and changed rom twice.

Probably not the same issue then. For some reason I had it trying to give me a static IP address that my router wouldn't allow (I've got MAC forwarding on my router to make sure that nothing other than the 4 things I have can connect to it).
When you connect to the wifi, can you open the router admin on your HD2?
Thanks for your help. No I cannot access the router from the HD2, could it be a proxy issue. I am not using a proxy for the internet

No worries mate - I hope I can help!
It's not a proxy issue, if you're not using a proxy server. Could you try this and let me know how you get on?
Start your wifi connection
Go to all settings, connection, wifi, wireless networks, network adapters tab
Select the Broadcom DHD adapter
It should be set to use a server assigned IP address, not a static one. It probably is, but it's worth checking.
When I open Wifi settings I can only open advanced no wireless networks or network adapter tab. How do I get there ?

After you've started wifi, go to the settings tab, menu and all settings. Then carry on the instructions in the last post.
Found the all settings, the DHD adapter is set to server assigned. Any other ideas ?
...
Well i think we have the same problem.. If you try to connect your wireless, do you get the failure after pressing get IP: Cannot obtain serverassigned IP....
http://forum.xda-developers.com/showthread.php?t=627654 my thread was this..
I found out that if i you go under WIFI>ADVANCED>press on the NETWORKCARD under the field "SSID"> then go to the networkcard>Broadcom 802.11 DHD network adapter>remove the pin in use serverassigned, and write a static ip: example: IP: 192.168.1.23
UNDERMASK: 255.255.255.0
STANDARDgateway: 192.168.1.1
That helped for me, though i cannot use that fix because my college wont accept the static IP. so it works for like 2 mins and then it disconnect. hehe.
Heh - that would be pretty much my next suggestion.
Try a static IP address and see if that works. It's not a long-term solution, but it would determine whether it's your phone or the router that's having the problem.
Last time I set a static IP address, I liked it and left it like that, but I found (after a couple of days with no internet access) that it tries to assign the same IP address when you use your data connection for internet access. Your service provider is very unlikely to allow you to use the same IP address, so you probably can't connect.
Like I said, it's a test to see if you can connect - not a solution.
Do you know what IP addresses your router will allow you to use? Do you have a specified range of addresses, for example?
I have this exact same problem. I can connect to wifi networks at home, office, etc... But no network access. It connects to the AP's, gives me an IP Address, but I can't ping anything!
This thing gets more and more frustrating daily.

It also happened to me. Turns out it was the router I was using. I bought a new one earlier today and problem solved!
Hi!
I got a d-link dgl-4300 router, and had problem getting a IP adr. from it. When I gave my HD2 a static IP it worked, but very slow. After I changed from DHD network adapter to NE 2000 compatible ethernet driver it get IP from router and I can browse internet through wifi fast. Maybe it can help u 2.

Wifi Works At Outside Wifi Hotspots but stopped working at home wifi... Please Help..

My HTC Desire HD Wifi has ALWAYS been working at my home wifi network.
Over the last few weeks, it has stopped working for no apparent reason. My pc as well as 3 other laptops work perfectly fine...
When I try to connect to my own wifi network at home now, it REFUSES to obtain an ip address and simply keeps disconnecting...
It however works fine elsewhere....
Anyway I can fix this problem or a simple way to manually connect to my home wifi network?
Thanks in advance...
hi
Have you checked that your security settings are the same on the router? also try and reset the router i.e. unplug for 2 mins blah blah. I know the lappys are working fine but this is what I would do.
I use to have issues like this with my HTC Hero, how i resolved it was by adding the phones MAC Code to the router software. Found in ( Security>Mac Filter ) depends on router! but is something like that. The down side is thou, you will have to add the mac codes from all your other devices to the router also, so everything connects to your ISP. It has the benifts of a more secure network.
Hmm, thanks for the possible answers so far.
It is strange. I just went to a friends house who also has wifi, I connected as normal.
It immediately connected with full reception. It seems that EVERYTHING connects and works as normal accept for my own home wifi...
I have tried resetting it, turning it on/off, it still does not want to obtain an ip address...
what is your make is your router?

It's Siemens Gigaset SE568
I would advise you against using MAC security on your router. Instead try to "forget" your home network (Settings->Wireless&networks->WiFi settings, then hold your home network and "Forget network") and then re-add your network. If this doesn't work try assigning static IP address (Settings->Wireless&networks->WiFi settings then tap "Menu" and "Advanced" but this will make connecting to hotspots more difficult (you'll have to uncheck the static address every time you need to connect).

Thanks for the response. I tried the forget wifi network and readd it, still a no go...
Strange how my phone works ANYWHERE & EVERYWHERE accept for my own home network...
It's not important/urgent so I'm not too bothered. I just think it's strange why it refuses to obtain an ip address...

Did you try to asign a static IP address (don't forget to test if you are connected to the internet after/if this seems to work)? Then you'll know if the problem is with the DHCP service or something else.
Ok. Sorry, I miss understood your problem! First is the router assigning ip address via dhcp as you don't state?. So the static ip method, You can try, Im here to help not say what to do and not to try..But as your pc and laptops are working I don't think the problem with dhcp.
A very quick test is to set your router to a open network and try to connect. Does this now work when you try to connect? We will work backwards to solve your problem. Also are you using a wizard cd software from the router? Or connecting to the router software via the internet explorer?
e.g 192.168.0.1 ? etc.

Just tried the static ip address, still refuses to obtain an ip address...
As for the router, it's automatic, we simply turn on wi-fi on the computer/laptop, click the wifi network, put password and simply connect as normal....
Strangely my HTC Desire HD refuses to obtain an ip.
A few days ago I went to my brothers friends house for the first time, turned on wi-fi on my phone, went onto his network, put the password and it immediately connected without any problem...
I'm 100% sure the problem lies with my old piece of **** router, well it's not mine but my fathers and I cannot exactly tell him to throw it out the window it's complete ****...
What can I do simply to make the router work with my phone?
Is there any new device in the network? If there is turn off all wifi devices restart the ap and try to reconnect.
Try changing the ap name too.
Hope it helps!

Last resort might be to factory reset the router, then putting all the settings (e.g. WPA keys) back on.

The simplest way is to set your router to a open network. Then no key is needed by the phone. The phone SHOULD connect with no problems.
You then no its a key issue.

If it's not DHCP issue then it looks like authentication one. So wipe the router's configuration and if this doesn't work either I have another solution for you. It involves a hammer and an alibi

Can't log in to my own wifi

Hi my problem is that, I can't connect my own wifi network. It stops at "obtaining IP adress from...". My laptop can connect to it and i can connect with my phone to other wlan networks too. Could anyone help me? Thanks
Are you sure that you typed password correctly?
Maybe you have mac adress filtering?
I guess u have DCHP enabled and not static IP right? Try push and hold your network's name on the available networks list and then "Forget Network". Then rescan and try connecting. Sometimes it works.
go into you router and set the DNS?
hi the password is correct I've updated my phone to the latest version because i thought that maybe the software in my phone gone wrong.

log into your router (normally 192.168.1.1), and check if you have DCHP enabled.
or you could try rebooting your router and connecting your phone first then your laptop.

Can't connect tablet and phone to same wifi

As stated, when my phone (HTC One S) is connected to my WiFi network, I can't connect with my tablet (A500, Thor ICS v170). It just keeps trying to obtain IP address and never connects.
Weird thing is, if I turn both devices off, connect my tablet to the wifi first and then connect my phone it will work. This only happens when my phone is connected first.
Is this a software issue? Is it something to do with my router and maybe a lease or some network thing? Please help..this is very annoying.

Did you check your router settings? It sounds like your DHCP is not set Automatic. Which router do you use? Making sure that you don't use static IP addresses.
Looks to me like you have a static IP configured for your a500, which conflicts with your HTC. Check settings on a500.

If he had static IP set in tablet it wouldn't try to obtain the address at all. It would just connect to the Wifi skipping that part.
@tgtoys:
I think that this can be a router incompatibility problem. Unfortunatelly not every wifi equipment is built with 100% conformance to the standards. Sometimes two devices just don't want to work with each other (and, for example, they both claim that are 802.11g compatible).
If you have a possibility then try with another router.
Other cause can be a router software misconfiguration. Router factory reset would probably help in this case but you would need to reconfigure your WAN and wifi settings. But this won't eliminate the problem if it is the hardware incompatibility.

Another problem I could think of is you have your phone's hotspot setting turned on that's why your tablet couldn't connect when there are two different Wi-Fi, that's just my guess.
Thanks all.
I am not currently using static ip on either device, and this seems to happen whenever I try to connect to Wi-Fi (home, work, and friends house), which is why I'm so confused. I will check settings on router when I get back. I haven't changed anything on the router other than add a wpa2 password...

The issue I experienced was the following.
I entered a WPA Password that had a large number of characters. Although the router accepted the number of characters, once I wanted to connect more than one or two devices I experienced the same problem as you.
I did get a WiFi connection but did not receive an IP and the connection was dropped.
After reducing the number of characters (but increasing the complexity) it worked fine.
Btw. it was a Netgear router.
I resolved the issue at work by assigning my phone and tablet with different static IP addresses on the router. How will this effect connecting to other routers?

When you say "other routers" you mean at your home? Or at other places like public wifi? If at your home, you can assign static IP addresses but not at public wifi because you can't control the router settings.
