[Q] Serios WiFi Problem since ICS -unrooted - Galaxy S II Q&A, Help & Troubleshooting

Hey,
I got a misterious wifi problem with my sgs2 and ics... some remote server aren't reachable after a while using wifi. Rebooting fixed it, but only for a while.
These server are, for example: ing-schwab.com, heise.de. All ports aren't reachable.
Using edge or 3g i can reach the server.
I tested this on 3 wifi i have access to. On two I sniffed a bit the network traffic with tcpdump. If my mobile want to reach on of these server the sgs2 sends following arp-request:
07:59:37.083813 ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 172.17.19.1 tell 192.168.0.20, length 46
172.17.19.1 was my router in former time.
192.168.0.20 is the sgs2.
In these net the gateway is 192.168.0.1.
I'm using dhcp, but also a manuel set of these data will cause the same issue.
I did a factory reset, but it make the same ****
Thanks for reading.

I forgot to say i'm using the orginal Rom i got per Kiesupdate.

X10 wifi SCANNING - DISCONNECTED loop! HELP!

Router information: Linksys Wireless-N WRT120N
I have done everything that i could think of to get this working. i have done several google searches and they all say to do specific things.
For example:
-Reset router
-Enable B/G only or G only set at channel 11
-turn off router firewall settings
-and a bunch of other random sh*t
i have done all of the above then some and i still cant get it to connect. all i get is *scanning* then *disconnected* thats the only two things it says. except right after i reset the router. every time i reset the router i get * obtaining IP yadadada* then goes to *disconnected* then back to the "scanning, disconnected" loop.
there have been some people that have said flashing a custom firmware on the router would fix the issue with mobile connectivity on Wireless-N routers.
please someone be helpful with this and please dont tell me i need to reset my router. i have asked this same question on several forums and the only replies i get are "if you reset the router and turn off security it WILL work fine" thats bull****. im not an idiot. thats the first step any computer literate person would take before asking questions.
**Update: same as from General thread. i had to repost because it was closed for some reason there. also here are the answers to the other two guys to responded.
"not standing close enough" -i have been standing next to it. i have yet to test it more than 10 feet away lol so it cant be there
"flash another rom or reflash current rom" -it has nothing to do with my rom, kernal, or radio. this issue is also happening on my girlfriends xperia running Wolfxperia and mine is the blackeditionHDv2. its also an issue with her sisters xperia. hers is still stock 2.2(i think). their stepdad has an iphone and it wont connect with that either. from what ive gathered... its a mobile issue. i know all these phones say (b or g only) but even setting the router to broadcast in b/g it still wont connect. it notices the routers name with full strength on all devices. also i might add that their laptop is an older laptop. does not support N but still can connect to the router and have internet.
Same here. Xperia mini x10 pro. When on it says connecting even thought I nothing appear visible.

as for me it just started, before that when i was at col i was able to watsapp as usual, the phone is currently not with me but when i get i will post some ss for you to see.

Here are the ss
any idea on how i can solve this?
I'm guessing this is an ip issue. The mobile devices are not able to get one. This usually happens to me on a public network and I even get a " limited or no connectivity".
The work around I do is to assign a static ip on my phone. Its very simple to do and if you need help doing it, let me know.
There's no clear explanation I can tell you, but it seems some mobile devices have a hard time pulling ip's from different types of routers. Hope this helps.

Will ask my gf to give it a try. It happened so abruptly, it was working fine when she was at col then when she came back it won't detect any wifi, whether it's her house or mine, and now that she is back at her col she still can't connect.
I know how you feel.
I have had this issue ever since I first upgraded to Stock 2.3.3 last July. On 1.6 and 2.1 (both stock also) I never had issues.
Basically, in my case, resetting the router DOES solve the problem, but only for a limited time. This limited time is random, as sometimes it will work for a few days, and then sometimes it will cut out a few hours again after I have reset my router. I am also using the static IP method (and an app called WiFi Stat which I initially thought had solved the problem, but it hasn't) I'm not sure what triggers the WiFi connection to be lost, but there must be a trigger. Like I said, I never had this issue in my previous old Android versions.
I had hoped (somewhat naively) that moving to a custom ROM would solve the issue, but after installing Wolf's latest ROM, I still have this issue.
Have you tried anything based on 2.3.4 or above, to see if this is an Android 2.3.3 issue? Are there any good ROMs people could recommend that are based on higher versions than 2.3.3?
WEP/WPA key issue?
If its not the kernel/ROM/version of the phone, it could have something to do with the way the security is set up for your router. I had the most frustrating time logging into my university's wireless (think it was encrypted with 802.1x EAP) which required username and password. Though most home-owned router are equipped with WPA/WPA2 PSK or WEP, you can try the steps below:
1. Go to Settings ->Wi-Fi Settings -> Add Wi-Fi network
2. Type in the network SSID (yeah this is the manual part)
3. Open the "Security" drop-down box and set the following:
Security: 802.1x EAP
EAP method: PEAP (default)
Phase 2 auth.: MSCHAPV2
CA cert.: leave unchanged
User cert.: leave unchanged
4. Type in username (if any) and password.
Once again, this would work 99% for 802.1x...not sure about WPA/WEP. Good luck!
Try Channel 6 in router option and hope it works.
Solve
setting a static ip doesnt seem to work.. any idea? i wish not to re-flash as i dun think that would be a permanent solution.
again i dun think it has anything to do with my router as other gadgets are able to connect with it and i didnt fiddle with the security.
It is unable to detect any router as i have tried it different hotspots.
Hope to get some help.
------------------------------------
I wipe clear the settings and it worked again.. hope the problem doesn't persist again.

Wifi-Issue with OpenWRT-Router

Hi everybody,
I'm having problems with my Tablet S when connecting to an OpenWRT wireless router (D-Link DIR-825). Half of all pings are getting lost (it's working for 10 seconds then for 10 seconds no pings are getting answered).
When using browser, i often have to reload page, because it is not allways loading at the first time.
Now I tried to temporarily connect my old Fritz!Box wireless router (on the same network). This is running flawlessly
So my question: Is somebody else running his/her Tablet with an OpenWRT device (with or without problems)? Any suggestions what could be going wrong here?
It's not openwrt, but I'm using a linksys wrt54g with ddwrt (v24-sp2 micro) and only having disconnect issues when large playing videos trought SMB sharing. Everything else is working fine. It's seems to have issues with high loads.
In others routers I didn't get this problem.
I'm also using DD-WRT and no problems at all, even with ICS , if anything I have slightly better reception now
I'm not running OpenWRT, but my custom *nix router is working flawlessly.
Check that you don't have any QoS rules or weird firewall rules set and see if that fixes your problems.
Hey guys I've recently checked that there's a new version 15 of openwrt........so I want some things to be cleared..
1.) Is there any size increment with this version..
2.) Will it be updated over Stone age version(3.8)
Lol...
My router is iBall-baton iB WRA 150 N adsl2+ single band router (best most selling and 30$)...
Ok it is nothing but a clone/rebranded version of TP-Link TP-WR741 and some guy at wrt forums posted mod file but the user is inactive and his links too..... i just wanna know if i am good to go... im over stock firmware.......and main concern is that WILL THAT ROUTER HAVE ENOUGH INTERNAL MEMORY TO FACE AND STORE LATEST WRT VERSION 15.**** ......IM Impatient to try out but is covered with dark cloud of fear of bricking......and if i did such thing,dad will kick me out of the house...seriously..thats why consultancy was the best option i was with....im on stock firmware version 3.0.0 and thats barely 2mb....and the version on site and the factory default version is same.... I'm not sure that is it full or a patch.. but i hope you can answer this question..

[Q] IPSec VPN Xauth PSK Connects but no data

I just got the evo as my new work phone. I attempted to connect vpn via IPSec VPN Xauth PSK. Everything connected perfectly but i can not ping my work network or connect to devices on the network. So its made a secure connection to my asa but is not sending or receiving traffic. this seems to be a similar issue that the transformer prime had. here is a link to google issue. has anyone else had this problem? please help!

PPTP VPN has come and gone on different Radio Firmware all the last 3 Sprint Android phones (EVO 4G, EVO 3D). But initial release of EVO 4G LTE got that right.
You need to narrow things down.
Are you VPNing from the PC or From the phone itself.
I suggest trying it with Phone on WIFI and see that works first (assuming your VPNing from the Phone).
If everything works on WIFI and then fails on 3G you may be in for a wait.
If it fails on WIFI you may have a setup issue or something that might get addressed in a Custom ROM or future Custom Kernel.
If your doing it from say a PC and WIFI Tether. WIFI Tether apps can influence things.

thanks for the reply. it doesnt work on wifi either... it would help a lot if someone has gotten this to actual work chime in or someone who is having the same issue as me chime in.
When your connected through the vpn I see you tried a ping, but can you try running a tracert to one of your PC or servers on the network and let us know what you see?
I'm looking to see where is your connection going to once your authenticated (if your fully granted network access)
Another thing you may want to check is what IP address is assigned to the phone when you connect.

Wi - Fi Problems, obtaining wrong IP [SOLVED]

Attention!!! I found a fix for getting wrong IP using your router!!!This should help you if internet worked at first day on phone or sometimes works and sometimes not after reconects. This thread i created is about my routers not working with SG3 and other devices. Router fails to assign right IP for my SG3. Example: 192.168.0.100-199(last digit from 100 to 199) should be IP in that range but phone aquires 192.168.1.6 or 192.168.1.8 and it can't get internet acces! I could connect but not surf the internet. To make device get always same IP and most importantly get GOOD IP wich would not be broken and you could surf internet. You just need to reserve IP in router's network settings. This fixed my problem instantly!!!
Thank me if it worked for you!!
----------------------------------------------------------------------------------------------------
Everything below is history!!
Pure stock, not rooted SG3 international version.
I have strange wifi problem. We have 2 routers. One is main(dlink) it was working fine for 5 days and sudenly my SG3 can't connect to internet. I saw that my SG3 is aquiring wrong IP 192.168.1.8 instead of IP192.168.0.(range of 99- 199) so it won't get connected to internet, but connection to router is good. Tried 2nd(linksys) not main router and it works, i can connect to internet (aquires right IP 192.168.0.138) something like that in right range from 99 to 199. First tried wifi fixers. Didn't work. Then tried factory reset didn't help too. Then hard reset from recovery with data wipe ( correct me if that isn't hard reset). That helped, but not 100%. Now i can connect. To main (dlink) router with right IP IP192.168.0.(range of 99- 199) and internet works, but tried with 2nd(linksys) and now problem has transfered to that 2nd router. I only can ask you. Why? What socery is this? Maybe custom rom i install from stock would fix this. Or i need to fix my problem without roming first? Strange.

Update: i lol right now. I went with my SG3 to googleplay via (main dlink router) downloaded angry birds seasons to see download speed. Speed was okay, played few mins. Tried to go to store again. Internet was gone. Internet works fine on my pc but on phone throught wifi not. And changed IP from 192.68.0.(last digit range 99 - 199 ) to 192.68.1.8. Now both routers have 192.68.1.8 IP as i connect to them with my SG3. Connection is strong but internet does not work, because of that freaky IP. I don't imagine how to fix this. My only thought is to flash my SG3 to custom ROM, because other devices works fine with these 2 routers.
So i flashed custom rom and it worked for a while. I guess because i did data wipe/factory reset. I thought i have solved the problem. Recently i installed FoxHound Rom wich is absolutely briliant. Then getting started app asked me to find wifi network. I sat near my router and... it again aquired wrong IP --->>> 192.168.1.8 <<<--- INSTEAD of 192.168.0.( from range 99 to 199). I i don't know what to do next! HELP ME PLEASE! :/
Our other device Galaxy Note works fine as ipad works fine too with those 2 routers.. But not SG3. Arrggh..

Now i have flashed other custom rom and SG3 aquires right IP. For now. Internet works fine. Will report later. Any advices appreciated.
-----------------------------------------------------------
Update: found this thread http://www.dslreports.com/forum/r22...-wireless-devices-aquire-the-wrong-IP-address.
He says:
"Everything connects to the router but getting internet working is only accomplished by manually changing the settings to those described above."
Maybe that's because my SG3 can act as modem too? Can galaxy note 4.0.4 act as modem or iphone4?
Unfortunately problem back again. Browsed internet for few min and got wrong IP as i came 3rd time to connect to wifi dlin router. Then i tried another router linksys and got instantly bad IP by connecting to it too. What to do now?!? It's definitely something wrong with my SG3. Do i need to reflash to original, reset counter and take it to warranty post?
Or maybe there is else i can do? Help!

why dont you use the [1 to 99] host byte range? I know range doesnt really matter but if your phone wants to connect to the lower part, why not change that? Plus, did you try giving your phone a static IP address? thats the first thing I would do
I tried doing static IP on my phone and I think I did it wrong. Now I have flashed again I didn't connect to my main dlink router firstly after I flashed new rom, instead I connected to 2nd Linksys. Downloaded 300mb game and few more apps from googleplay, installed, restarted, reconnected and it still works. Will report later how it's going.
Sent from my GT-I9300 using xda premium
All those few days i was connected to 2nd linksys router. So it worked flawlessly until today when i tried to connect to main router dlink. First time i connected today it worked fine. Second time i got that EPIC FAIL IP 192.168.1.6 now. What the F***?! I resetted that router like 5 times to zero and reentered ips. All other devices works fine with it. Why not my SG3?!?! And my computer threw strange internet connection error but it wasn't affected by it. Internet works on my computer as it should. Error was about double ip. It said that other computer in the same network had the same ip. But it works fine after that error. I'm carring my SG3 to warranty post. I don't know any other options.
Edit: After 5 min tried to connect. It works now again just by reconnecting. Previously it didn't work that way. If it stuck, it was always stuck with that ip even if i did "'forget network" then "wifi off" then phone restart and wait some time. It could only work for some time if i did hard reset. Will see what happens next.
After another 5 min i tried reconecting to 2nd linksys router and now it has wrong ip 192.168.1.6 (not 8 at the end). But i get good in on main dlink router now! So main working and 2nd - not. Wtf... So this problem isn't caused by main router dlink. I now really believe that my SG3 has something wrong. I i will lose my connection again (can connect, but no internet), i will take phone to service.

if you somehow get your phone to connect to the internet again. Just go to the router's configuration window and increase the lease time to max (say 1000hours). That way, your device will get the same IP for at least 1000hours

What's point of doing this if i go to other place and same thing happens. I will increase time there too or smth? I need to fix roots of the problem. Other devices works fine, but not SG3. Do not know.. Will installs few new roms and take it to service. Internet works now with main Dlink router but no linksys (other connected after main). I first thought it can be main router only. I thought when main locks with bad ip so other router gets bad ip too, but i was wrong. So no point in fixing routers, because if i go to anywhere else and there my SG3 lock with bad ip what then i should do? That's the point
This time i tried onother samsung galaxy s3 wich is not mine. Gues what. It bugged the same way. LOL. But somehow unbugged to correct ip after 5min when i did reconnect on that phone. Same thing happenned to mine with new rom. I jst installed new rom on mine and instantly as tried connecting got wrong ip again. But after 5mins~ turned off wifi and back on and it started to work again. Same s*it with both SGS3. I gues that's samsung fail with wifi. Wich cause with some routers to work wrong. And again all other devices have no problems with these router wich have SGS3s. I think i will have to live with it or buy other router.

So router with my sg3 worked for some time for few day and locked again. BUT FINALLY I FOUND HOW TO FIX THIS PERMANENTALY!!! YES!!!
To make device get always same IP and most importantly get GOOD IP wich would not be broken and you could surf internet. You just need to reverse IP in router's network settings. This fixed my problem instantly!!!
Reverse IP, what does that mean?

Is it password protected? If so try making it 'open' or change the encryption type.

Hi,
first thanks for the quick reply,
yes the network is password protected...I changed the encryption type for the WPA not the WPA2 and the problem still persists...
the thing that kills my brains is that, to connect to the bridge I must restart the the access point every morning,....
thanks
Do you have DHCP enabled on the 2nd router?

yes, I guess so....., should DHCP be enabled or disabled?
sorry but this situation is driving me crazy.....
I cant connect to the brigde/extender network right now with both my android phones and android tablet, however with my laptop running windows 8 I can......
wth??????
this is so frustrating!!!!!
Are you sure the second device extends the main access point and not just create a new WLAN?
Have you updated the firmware of both devices?
What devices do you have?
Am I understanding correctly that your laptop does work even though both Android devices don't (before you reboot the extender)?
Nope...its not creating another wireless lan... it extends the main plan correctly cause my laptop connects perfectly to the Wi-Fi from the extender even prior to the restart of the extender....
The devices are...main router from the ISP- Thomson
Range extender- tp link 701nd
Thanks

Both have latest firmware? Might be a bug in the WiFi driver of the AP/ROUTER... or it's in Android.... you will need to test by trial and error I guess...
Ok..
Do you guys know anything if I must have my IP static or dynamic?

Dynamic would be the friendliest to work with... you could try if it's a DHCP issue by setting a fixed IP when the problem occurs, but I don't think it is.
This is not a problem with the phone(s)....is with the router config. Contact the manufacturer for further assistance...

If you got a router and a range extender, there's nothing you need to fiddle with because the range extender will just Relay DHCP requests between client and master router.
Two routers* pushing out IP addresses is a no go, there will be a conflict in your scenario, and all range extenders will of course take this into account.
If you had two "real" routers*, it would still be possible to set everything up, although then there's a lot to take into account.
* Router is a inaccurate term used for the consumer grade combination devices. They're in fact a router, a switch, and a wireless access point bundled in a neat package. Sometimes with a xDSL modem or something on the external interface of the router.
Try setting the IP to static and more important, try giving it a default gateway to the routers IP. That should make it easy for your phone to directly look for the gateway it is looking for.

I have three routers, one main, one extender, one repeater (creating a whole new network for other building). Both main and repeater are the same network. All is config as per DD-WRT documentation. All three have latest DD-WRT.
After trying many things, all I can say is the (or mine at least) S3 always has trouble when many APs are nearby. I don't use VOIP because of that (it could disconnect at any time).
Next step on my list is to have 3 different SSIDs (only two now) and try using tasker to debounce the wifi switching (if that is even possible).
