Obtaining IP address - Sony Xperia P, U, Sola, Go

Hello guys, my phone model is Xperia P LT22i (unlocked and rooted) When it auto connect to saved AP, sometimes failed to connect. It stops at the stage of "Obtaining IP address". It's difficult to observe that because the problem does not happen each time. I also found that it only happens at home. I don't know the reason but I have done a lot of things:
use Static IP
change Channel
use 11g only
assign auto IP if DHCP fails
and even reset router
the problem is still here. I found that the only method is to manual connect. My friend told me that it might be nearby noise caused by other routers. Then I change to Channel 13 which fewer people use it. My phone got connection smoothly but the internet speed becomes strangely slow. Obviously, Channel 13 can solve the "Obtaining IP address" but also bring a slow speed problem. And one more thing that I consider is why my other devices, such as tablet and laptop, don't have this issue if it really caused by noise? Is it a Xperia P ROM bug? Anyone experienced this?
Thanks

can u help me by telling me what is channel 13

I have the same problem with my phone. Anyone found a solution ?

How to set Phone's Identity for WiFi?

Hi all,
I'm having a hell of a time keeping my X10 connected to my home WiFi router (a Netgear DG834). If I reset the router, the phone connects and is happy for as long as you like.
turn off the wifi, or move out of range, and it will never connect again ... unless you reset the router.
*sigh*
Been trying lots of stuff and it seems okay to connect over an open connection, but that's not satisfactory.
On further investigation, I've discovered that the Router detects the phone, but doesn't issue an IP address and I believe this is because the Phone does not transmit an identifier name, just a MAC address.
SO ... HOW DO YOU SET THE WIFI IDENTIFIER NAME?
Thanks for any help offered.
regards,
S.

DG834 the same router as i have, I have the V5 version, anyway I had exactly the same problem, will not connect to it once you turn off wifi or move out of range, just says scanning on the phone.
Anyway the Fix is to download the latest firmware for your router, make a backup first but i didn't need a backup, install the latest firmware and it should be ok, I know mine is
I've been having the same problem as you with the wifi, with the router not issuing an IP address, but didn't realise that was the problem.
Just tried resetting the router and it worked. However, when i got back to my laptop, i noticed that there had been an IP address conflict between the phone and the laptop.
Just something to throw in there...
Cheers both.
Router firmware is at the latest according to Netgear (I have the same model, just couldn't remember the version number)
I'll check the IP Address conflict, but with the router set as DHCP, along with all my assorted PCs all set to ask the router for an IP address this shouldn't happen, unless the Phone has a fixed IP address in it somewhere.
Hmm.
Weirdly I turned the wifi on this evening on the phone and it connected immediately and had no problems. Will have to keep watching and checking I reckon - there's not a consistent fault here...
Just plugged my headset into my X10 and bang its lost the Netgear 834, there is defo something wrong with X10's and the most popular router in the world lol
I am going to try and see if it loses my [email protected] fast 24 router provided by Sky Broadband, will let you know if it's Netgear specific.
Must be a Netgear thing, my sagem works flawlessly, I install 834s all day in work, we have approx 150 of them out there with customers, I cannot belive this phone is not fully tested with it Can someone try adding the MAC address to the list of permitted devices and see if it holds connection then?

wi-fi connection

hello
i was so looking forward to getting my new x10 mini pro only to find a few faults some of which i can live with until 2.1 comes out (should really be 2.2 & sooner) but i cannt seem to connect to my wireless router.
i have tried several different methods, including going through all the wireless channels on the router, enable mac address filter and have only my x10 set, try all the differents security settings - but still i cannot get my phone to obtain an ip address before it gives me the unsuccessful message.
so went to mcdonalds tried their openzone and connected fine to their network.
now my next guess would be is my router is old (about 4 years maybe more) linksys WRT54GS so anyone know of any problems with specific routers at all?
i know i had problems setting up my godsons ipod touch with my router, but didnt dig any deeper on it as he wasnt fussed about it at the time - so think it could be that but will hold off rushing out to get a new router for a while yet, probably to test some other peoples routers first.
Is you SSID hidden?
I have found that on some routers, Android phones in general won't connect if the SSID is hidden.

The WRT54GS should be a perfect router to use.
Make sure you are running latest dd-wrt firmware on it, setup wifi security as : WPA2 Personal Mixed, TKIP+AES
I have these settings and phone connects easily.
Its a good router, do as above poster advised and definitely get latest firmware on. Try going on just G mode if there's no B-only old wifi gadgets in your house.

I noticed my wife's X10 mini won't connect to Channels 12 and 13. If your router is on one of those channels, try moving it to 11.
I have difficulties connecting to my wifi router at home, SMC Barricade N2, WPA2 authentication, it works only after resetting the router.
Now after turning off TKIP cypher suite (only AES), it works perfectly
update: and also helped to enable static IP... but I am using wifi only @home
Had the same problem. Changed to Channels 11 and detected imediatly my wifi network.
Hi, I have a different problem with the wifi.
At work and some other connections I've seen to have an open wifi, which i can freely connect.
However, I am still unable to browse the internet as it requires some browser authentication.
I've seen other fones (Nokia and Iphone) have their browsers popup a webpage to input the credentials.
but my mini pro doesn't display this page.
i've already tried going directly to the login url manually but still doesn't display the login page.
someone told me that this might be a limitation of android but haven't seen any reports about it...
i also saw and tried 2 apps (Open Wifi Login and Browser Wifi Login) that should have solved this but did not.
Has anyone else had this experience?
Help please....
shameless self-bump
other fones seem to have the same issue but no solution...

Ip adress problem

Hey all, my problem is this; each time multiple devices try to connect to my router, it starts to fail after assigning 3 or 4 ips, meaning the next device trying too connect doesn't get an ip assigned, which really sucks for everyone in my family, since we al use wlan on our phones, and when the router is unplugged and plugged back in, it does it job again, until the problem appears again. Anyone can help me on this? All help is much appreciated
Check the scope range in the dhcp settings on the router.
Check your router manufacturer's website and see if there is a firmware upgrade.
The range is big enough I think I will check for firmware updates tx for your input

Galaxy S2 is able to connect to wi-fi router but can't access Internet ??

hi,
I've linksys wi-fi router model WRT54GH in my home & it has a good amount of signal strength to cover entire area.
My recently bought galaxy S2 is able to identify linksys wi-fi access point & connects too with the IP assigned to it, also at wi-fi settings connected being displayed.
Now when I try to access Internet (any url google/FB), it doesn't connect at all.
I tried almost everything about router configuration, restart etc. but with no success
can someone plz help on this ?

In my case the problem was with frozen "WiFi sharing" in combination with juicy defenders "Location" fearure. It seems such combination is dangerous. Solutin (in my case):
1. defroze
2. remove all wifi networks
3. reboot (for "clean" frozing)
4. make WiFi sharing frozen
5. reboot again just for fun
Try to check your router's MAC address restrictions. In my router, as security, I have to add MAC addresses of each device to share internet. They take IP's, connects etc. but does not have accesses to internet
as above, check that there is no MAC filtering set up.
one other thing it may be is the security settings, if you have a WEP Key to access the router it may need the Hex conversion of your key depending on what level of security you have (64bit or 128bit for example)

Try setting up a static IP address for your phone, I presume your network is a 192.168.1.0, go into router settings and LAN setup, give your phone the address in a static DHCP assignment of 192.168.1.5, or any other address in the same subnet your in. Some SGSII's have problems with dynamic DHCP for some reason, some NS had the same problem too,

I have a similar problem and I fix mine temporarily by turning my wifi off, then in wifi settings > advanced, I change wifi sleep policy from 'never' to 'only when the screen is off'. However I have to do this every time I want to use wifi so it can become quite annoying sometimes.
So I can get through however only for a short period of time as it seems as long my Galaxy S2 keeps turning off my wifi even though it's on :/
I had exactly the same issue on Linksys E4200 with my laptop, could connect to network, even to router's attached storage, but not to internet. Restart helped
On SGS2, I couldn't connect to the router at all at first, but fixed this by switching from WPA2/WPA mixed mode access protocol to WPA2 private. But I guess this is not exactly your issue.

Yes, you are right this is not an issue for me.
In fact my SG2 being assigned with an IP address from 192.168.1.xx subnet.
Also at a same time my laptop connected with an IP from same subnet able to ping SG2.

My SG2 being assigned with an IP address from 192.168.1.xx subnet.
So I think IP addressing may not be an issue.
Also another thing I tried was, at a same time my laptop connected with an IP from same subnet able to ping SG2.
So wi-fi router may not be an issue here, whats say ???
Even I am facing the same issue at my office network. I am able to connect to the wireless network but if I try to access any app I cannot browse. This is really frustrating looks like some issue with the modem drivers.
I was able to browse on another wifi created virtually by mobile tethering. This looks like a major bug with the current firmware. Another interesting thing to note is that the Wifi network has a hidden SSID and uses WPA2 auth scheme.
I have seen a Galaxy S able to connect to the same n/w without any issues.
Has anyone figured out a solution to this one ?
Hi, thanks for your reply.
I am yet to figure out a solution for this
Even I am also agree on the probable issue with modem driver.
I've D-link modem.
Are you aware of anything about this modem that can be reconfigured to get this worked ... ?? pl let me know
The wifi router at my office is Cisco Aironet 1200 Series, anyone else facing this issue ?
I'm having the same problem at work connecting my SGS2 with v2.3.3 Official Firmware (customized for Orange service provider) to a Cisco Aironet 1130 AP. I can see that the Galaxy authenticates with the AP correctly and gets IP from the DHCP server, but it cannot send or receive any traffic, although the phone stays connected and authenticated. At home, I use an Atheros based Fonera with DD-WRT without any problem.
As I'm the company's network administrator, I will try to further investigate this problem, but it seems like some kind of incompatibility between the devices or misconfiguration ....

try turn off the wifi, turn off the mobile data and turn on the wifi again
It seems the SGS2 sometimes has problems with DNS.
Try a static IP and use 8.8.8.8 as second DNS server, which is a free Google DNS server.
This fixed MY problems
I rooted my SGS2 and voila wifi worked at my office finally I have been able to find a solution.. love my SGS2 the Beast...
I'm having this same problem..
I think I've tried all the solutions above, but one (Sorry - noob question):
Rooted?
is there a firmware patch or something that I should know about?
Anyone got any other ideas?
ETA:
I can connect to hotspots (DHCP) and at home (Have to set it to static tho)
No internet
AP works - Laptop and i8910 (had to set static and advanced settigs etc). I've rebooted it a few times, set DHCP on and off. DHCP seems to be running on the router

This is an issue with SGS2 with wifi server using authentication protocol TPIK, if you use AES as encryption then it will work without any issues.
That should be a setting in my AP? I can't see it...
If I get a new non-crappy AP is that likely to solve my problem?
ETA:
Ah - that's a WPA thing? Mine only seems to do WEP - is that right?

S3 can connect to WIFI but no Internet

Hello everybody.
Since last saturday i'm testing a Galaxy S3.
I want to test if everything works properly before buying it.
I have some problems deling with the WIFI stuff.
I gave him a static IP (192.168.1.15), configured the gateway as the ip of my router (192.168.1.1),
the network class is 255.255.255.0 (network prefix = 24), the DNS points to the IP of the Router (192.168.1.1)
It connects without problems. form the S3 i can ping any device in my network and from other devices i can ping the S3.
I can connect to the configuration site of the router and from the page of connected devices i can see that the S3 is connected
with the correct ip and also the MAC adress is correct.
And for now everything is fine.
Problems raise up when i try to surf internet. The answer is always "Page not found"
If i open the browser and try to navigate to google] the answer is "Page not found". Same for any other site i try to connect with.
I cannot ping external adresses from the S3. Only the ones inside my LAN.
On the same LAN there are 3 laptops, 1 IPhone, 1 TV, NAS NETGEAR , home automation screen, all connected in WIFI.
All of them configured in the same way. (static ip, gateway=ip router, dns = ip router, network class 255.255.255.0),
And they all access internet without any problem.
The network is protected with WPA2/PSKey, encryption AES.
I tried to configure channel with WPA, WEP, without protection, but no changes.
The S3 connects to router but does not connect to internet,
I also tried to make it point to a public DNS 8.8.8.8. No WAY!
Works for other devices.
I tried to reset S3 to factory parameters, same thing i did for the router.
I reconfigured everything from scratch but no result.
I do not have any filtering based on IP or MAC adress on my Router.
I tried with DHCP, with reservation of IP adresses or without reservation. No change.
Other devices can access internet. S3 does not.
I have to say i'm quite desperate.
If you guys have some good ideas to solve or diagnostic the problem i would be grateful.
Cheers,
Fabio
I get that around my office as I walk around, I find that when I change AP in range my internet connection drops. I have to constantly disable/re-enable WiFi.
Even around my house, I have the handset to WiFi always on, yet when I wake up in the morning the internet connection is not working yet there is an IP. I couldn't be bothered to telnet to port 80 etc., but I hear that the Jellybean update will resolve this issue.
Same problem

Oh poor fellows ....try to add DNS manually according to your ISP...not add public DNS
Try forgetting the network and connecting again and make sure all the other devices are using different ip address
