WiFi data transfer problem

I have a ZyXEL P-2602HW-D1A Wireless router. I have tried all combinations of security, even NO SECURITY WHATSOEVER, and still the device won't transfer data.
Not working;
Firmware: 1.5, Build: CR817
Wifi Router: ZyXEL P-2602HW-D1A
Security: Tried All; WPA2, WPA, WEP & None.
Problem: Connect under all conditions but no data is sent
Please help.

Have you tried another WiFi access point to check the devices WiFi module actually functions?

No, I haven't tried that yet, but don't really see the point... I've connected effortlessly to the same WiFi network with my HTC Touch Diamond.

For some reason my N800 wouldn't connect to MY ZyXEL P-2602HW-D1A unless I set the device (N800) to disable any kind of wifi powersaving features it had.
On another note, how did you get your hands on the device so early? I'm guessing you are using a Cybercity internet connection? (I'm in copenhagen myself)
edit: I actually came to that solution when i noticed I could connect to OTHER accespoints, but not the Zyxel ones.

Same problem here in France with a Freebox as router

I've noticed under the router's WLAN client list that the device does not have a "Host Name". Would that present a problem?
It is assigned an IP address by the router without any problems, though.
Also the device seems to lose connection and reconnect constantly (every 5-10 seconds).
I done some digging around in the router settings and found an "AnyIP" feature. Would that possibly help?

There are a number of issues floating around. Support for WPA2 seems iffy and some people can just change to WPA or WEP and all work fine.
There are however a number of people (such as me) who can get a connection perfectly, it shows connection OK, they get an IP from the DHCP server etc, they can even browse a page for a few seconds... but after that no data is sent and everything times out. This is happening on any security from none through to WPA2.
I have seen no solution to this anywhere and believe me I have looked. Some people have given up and got a new router, but this is not a solution.
Can someone confirm that this has been recognised as a fault with the magic and is being investigated, rather then assuming it's a user or router error. There are far too many instances of this across many brands of router for it not to be an issue with the HTC Magic.

What I mean is have you tested the device on ANY other AP except the ZyXEL?

No, but since I'm by far the only one having this issue (try searching the web; see my last post), I didn't feel it was necessary. Just want some input from xda-dev that might solve the problem, if any.

I've had exactly the same problem earlier with the N800 on the zyxel. Exactly how you describe it.
Did you find out if you could turn off any powersaving features on the HTC?

same problem here
in france with a freebox
I don't exaclty know what router is in the box
but I have excalty the same
I set on never the wifi sleep(powersaving) mode.
i found it in setting wifi menu button then advanced and "never"
but the problem is still here

I have the exact same problem on mine. I just hope it is not a hardware issue...

Could be DHCP lease time problem. Did anyone of you tried to set up Magic with Static IP?

Yes, I tried that also - didn't help one bit.

I also have this problem. Im in Denmark with a Zyxel P660HW-p1.

Another user of Cybercity in Denmark with the same problem.
ZyXEL P-660HW-D1
The android is the only device that doesn't work. I have tried with Iphone and laptops.
I've tried to change the settings on the router to no avail.
Enable 802.11g+ mode [on/off]
RTS/CTS Threshold [2432/4096]
RTS/CTS Threshold [2432/4096]
Max. Frame Burst [600/1800]
The device shows up in the device list with no hostname, the HTC Magic gets the right ip address (using the program WhatIsMyIp to view it)

I had the same problem before, when I set my TP-LINK draft N router with WEP security my HD can see it, connect to it (but speed was slow tho), and my HTC Magic just keep saying its not in range. However, when I set it to open security it works, so I recognise its probably the security setting... so I changed that to WPA2 and then it works.
In my case, I see different device have different tolerance to some settings (in my case, draft N + WEP is OK with laptop, HTC HD, but not Magic), so its still worthwhile to try a few different settings, and try a public wireless access point also to double confirm?

Power save?
I have Zyxel (P-2602R-D1A) router.
I had exactly the same problem with my HTC Vox (winmo)... but that was solved by boosting the WiFi in the phone.
WiFi -> Best performance
So Im guessing magic is in some WiFi "power save" mode...
I dont know how this works, but I thought maybe you could change some WiFi settings behind the hood - that is if the hardware is capable of it.

Zyxel (P-2602R-D1A) router
I am having the same issue with this router as the other posters. The phone connects perfectly and reports an excellent signal, but barely sends or receives any data. I have used a terminal emulator to ping the router and it reports an 82% packet loss. This must be a big problem for many Danish users as it is the standard wifi router provided by two of the major ISP's.

same issue here with my vodafone uk magic.
wifi connects and i can browse for a few seconds then get a connection error and can't browse until i re-start wifi on the magic...
i've actually given up using wifi at home now due to this.
router is a talktalk supplied Huawei Echolife HG520b using 128 bit WEP
i can connect fine via wifi at the office so i don't think it's an issue with the handset, just with certain routers or router configs...
this issue has been reported on the vodafone uk forums but as yet no solution.

HD2 cant connect to wifi :(

Hi All,
Just got my new HTC HD2 from Virgin, however I cannot for the life of me seem to connect it to my home WiFi (I've not tried it elsewhere yet).
I've still got my MDA Compact IV here with me and use the same settings as the HD2 and that connects first time no problems, but the HD2 isnt playing ball!
It sees my wireless network at home (full strength) and starts to connect then simply says "Available". No notification of incorrect wireless key etc...reported.
I have used my Compact IV side by side with the HD2 and no issues so I am puzzled as to what I need to do now
Any help would be appreciated.
Thank

Are you sure you didn't set up some MAC address filter in your wireless access point?

I've not enabled MAC address filtering on the router at all, just simple wifi security key access.

Flash a new radio?
(check my sig under hspl flashing guide)

if you are using wep, heres something to try.
routers can be set to three types of wep key
open
open or shared
shared
in my experience if you areset to the middle one, "open or shared" mobile devices can have trouble connecting.try setting it to just "shared"instead.
course it could just be my router but I have seen this behavior in three mobiles including my hd2.

Current router settings is WPA-PSK [TKIP]. I even tried turning off security and got nothing My router is Netgear WGR614v9 - it came with my Virgin broadband deal.
Current ROM version is 1.48.405.2 (71294) WWE and radio version 2.05.51.05.2
Its most annoying that the HD2 on the face of it seems like a really good handset but then I cant get the Wifi connected which most basic handsets have no issues with
Any other possible solutions?

I got the same problem
I have the exact same problem.. Cant connect to my AP with my leo... got no mac secure on, even if i remove my security(WPA/wep or whatever), it will not connect...

I had the same issue when I applied hint 39 from http://forum.xda-developers.com/showthread.php?t=583638
Result: couldn't connect to my network with WPA2.
After restoring the parameters everything is OK.

Right finally got it working!
Installed the Touch_X_Wireless_Draft_N_ON.cab cab and then uninstalled it and now it seems to work.
Cab can be found here: http://forum.xda-developers.com/showthread.php?t=584415
Hope that helps others out too

I had this issue too, could see my home Wifi network, but the device would just say, "Incorrect Network Key". But it was correct!
I now have it working strangely by changing router Security Options to (WPA-PSK + WPA2-PSK)
Connects with no hesitation now!

my advise is disabling WEP password in both HD2 and the router.
it works perfectly.

"Incorrect Network Key" problem
Bro you made my day! I spent whole day to figure out a solution to the exact problem. I wish I had seen your reply before. When I changed my cable modem's setting as suggested and encryption to AES, it worked
Thanks again.

Wifi obtaining ip address....

My Wifi connected to my home router perfectly until I flashed the custom rom.
Now it wont work. the phone recognizes my network, then tries to connect but it pauses at the obtaining ip address bit and doesn't connect?
I tried to restart the router. It doesn't work.
I tried to reflash the rom or offical rom (KE7). It doesn't work.
I also tried to delete the file /data/misc/dhcp/dhcp_list, but there are no "dhcp_list" file inside 'dhcp'
Do anyone have another way to solve this problem?
Thanks

Could be a problem with the router, are other devices able to acquire IP addresses from it correctly?
Perhaps you should assign a static IP to see if that makes a difference.

I am on KE7 stock rom with root and had this problem too. It just started yesterday and got stuck at obtaining ip adress. So I switched WIFI off and flight mode on and after some seconds wifi on and flight mode off and it connected. I also noticed that now sometimes when it is in standby it disconnects from the wifi network (but wifi is still ON) and when I wake it up it connects to my network.

Me too, same problem.
If wifi is ruled on "sleep when screen turn off", it don't wake when screen turn on.
It stay on " searching for IP adress...".
For the moment, I'm forced to leave wifi on "never" and I use Juice defender for disabling wifi on screen off.
I really think it's a common pb with SGS 2. May be it will be fixed with 2.3.4.

Same problem. I 'fix' it by turning off wifi then turning it back on and it gets an IP address immediately.

same problem here with a dlink dir-615 router. from time to time the phone can't get an ip, and it only works if i reboot the router. didn't try with another router yet ( well, i connected to a few more but not frequent so i can see if there are problems), but i ordered a new one anyways since the dlink also crushes my battery too.
try posting the brand/model of the router you have problems with, maybe there's some specific ones that are troublesome.
d-link dir-615 here / ke7 stock - rooted

I also have a dlink router. But I get the same problem with a Belkin.
With my first SGS, no problem. I really think it's a specific issue on SGS2.
I'd read in some place that 2.3.4 will fix some wifi problem known for the moment on 2.3.3...
Let's see...

I'm seeing this with both my home router (Netgear WNDR3700) and my office router. Disabling & re-enabling WiFi on the SGS2 solves it -- fortunately, it's easily accessible on the notifications panel.

Same thing with Dlink dir 815.

Same thing here with Draytek 2820 router, all other devices (PC's Phones, PDA's etc) have no problem. SGS2 however needs WiFi turning off when waking from sleep to get it to obtain an IP address again. However my HD2 also running Gingerbread 2.3.3 works faultlessly.

KF2 seems, for me and some others, fix the problem...

hi
lucky me, i thought im the only 1 having problem with wifi
my problem, same as the others
the wifi try to connect (obtaining IP) and then disconnected
it will scan again, same thing will happened
try with all type of protocols, wifi b,g,n wep, wpa, no passwd
results still same
try to connect wifi at my office, results also the same
im on KF1 using dlink 615
hopefully someone can help us
tq

Just got my Galaxy S2 today. Cannot connect to wifi network on G or mixed mode, with or without security - just tries to obtain an IP address. Ridiculous.
Any help ? Quick search on Google doesn't bring up too much. There does seem to be an app called "FXR Wifi" but I don't expect to use that on a brand new phone.
Update: Upgraded my router's firmware (WRT54GS) and it works !

I have the same problem with my SGS 2. I can't connect to an AP - NETGEAR DG834G.
I found a partial solution to use my phone with my AP until I solve the problem. In the Wi-Fi settings menu enter Advanced mod and set the IP address, Gateway, Netmask, DNS1 manualy (by touching <Use static IP>). If you don't know what IPs you have to set for IP address, Gateway, etc. just connect with you laptop or desktop and use the settings from your computer. Just make sure you type a different IP address in your mobile (not the one from your computer - for example in you computer you'll find something like this: 192.168.0.3, you'll have to type in your mobile something like this: 192.168.0.10). The rest of the settings have to be identical.
Good luck!

To solve this "obtaining ip address problem". Set the following manually in the advanced configuration and save it.
1. ip address(your choice).
2. subnet mask(255.255.255.0).
3. default gateway(192.168.1.1).
4. dns servers(8.8.8.8,8.8.4.4)
Note: The above given values are the most commonly used, you change it if you want so.
After entering these values manually(and correctly), it will connect to the networ in 1 or 2 seconds.

like mine SG s2, wifi connects works perfectly at home and friends place,
but stucks at obtaining ipaddress for wifi, at the mall and college, ( where it needs first login page for authentication) ( or to agree user terms and regulation),
any idea, how to fix this issue.
Thanks

mine also does this where it doesn't get an ip. Reboot your router or just disable and re-enable the access point feature on the router and it should work without having to reboot it

Hey guys! Did you find a fix for this problem? I have the same thing happening right now. I tried at different places, home and country house with Zyxel P660HN and Cisco E4200 respectively. Stuck at obtaining IP address...

Xperia "Limited Connectivity" problem on Wi-fi

Hello. I'm new to xda. I have problem with my Xperia X10i. When I try connect to a wi-fi network it take forever to get its ip adreses and i don't know if it succeeds or not because after that is say's connected with limited connectivity. I have searched the web and xda but nobody has a solution to this problem. I am running Android 2.3.3 updated through SEUS. Not rooted or anything. What can I do?

I had the same problem, so I feel your pain. Go into android market search wifi fix..if the app doesn't solve the problem,reset the router. Hope this helps.

the only issue i am having with wifi sense ive had this phone has been connecting to linksys wireless N routers. i have turned off N functionality of the router using b/g only but all the phone does is alternation between "scanning/disconnected" doesnt try to obtain IP address or anything. its only those routers i have issues with. belkin wireless N works fine (with N turned off of course)

I had a similar problem, I solved it with wifi fix, thanks.

If you updated your x10 through the SEUS...its probably problem on your wifi router..try to reset settings and power off your router..

Okay, so I'm trying to help a guy with his Xperia X10a. He doesn't have wifi working and does not a have an account for the phone so no 3G. He needs to download wifi fix, can he just download it on his computer and then tether it and sideload?

1.make sure that ur access point has internet access.
2.if there's no server then ask ur ISP about static IP & gateway
3.if there's a server..then ask if u can get a static IP
4.also try "forget" then reconnect and if the wifi with a password then it might be wrong

don't connect ur modem in bridge mode.......

Still not working
I have tried the wi-fi fix app and nothing changed. I have found a temporary solution in witch you use static ip on your phone. But this solution is just for home because in a pub or any free hotspot it still doesn't work. Now I have flashed CM7 to my x10 and the wi-fi seems to work a little bit better but not perfect. And the wi-fi range is also poor on X10 compared to a Iphone 3GS or even a Optimus Black.

i think problem is your wi fi modem , try to setting your modem again ,
Go to setting >Wireless > Security
and
Select SSID: Modem Name

WiFi connects to my router and stays connected at excellent signal strength without any trouble. Internet connection however, always disappears after a minute or so. Then my Dolphin Browser either keeps loading a website forever or gives me some error like "Webpage not available". Same story with stock or any other browser. I'm not sure since how long I have had this issue. It surely existed already when my phone came back from warranty service (and I had sent it there because of very short range of WiFi commonly known problem which they fixed by giving the phone new hardware). I think that upgrade to Android 4.2.2 might have caused my problem, but it was such a long time ago that I don't remember now (I don't use/need WiFi that much, mobile data internet is enough for me).
What I've tried so far:
-rebooting phone and router obviously
-factory formatting the phone
-WiFi analyzer app
-changing all the network parameters and re-setting it up
-WPS connecting
-playing with all the WiFi settings on my phone (proxy settings, ip settings, wifi optimization and other)
-finally, today I unlocked bootloader, rooted and installed custom ROM hoping it'd help (but it didn't and now I lost my warranty lol)
What I have:
HTC One X Endeavor
Android 4.2.2 HTC Sense 5.0
Android Revolution HD 33.1
3.1.10-g7f360be Kernel version
TP-LINK
N750 Wireless Dual Band Gigabit Router
Model No. TL-WDR4300
I'm thinking about installing other ROM, some that works on Android 4.0 or KitKat, could it help?
Oh, and I should add that two different notebooks, Galaxy S4, S3 mini, Xperia X10 and a tablet all work fine with this network :>
I can provide any screenshots, photos, names of devices etc., just tell me what is needed.
HELP!

I have a similar problem with my device, but I just reset my router and it's fine. Maybe your problem is that your phone doesn't receive an ip address. You can check out if you have received an address via settings->wi-fi-> advanced, and check the 'ip address'. If it says ' not available, reset your router and your phone's wi-fi until you get one.

Nopes, IP reception is fine. Here are all my settings:

Signal strength: Excellent
Link speed: 26Mbps

As I said earlier, I have been playing with all the network settings above as well as with the phone WiFi advanced settings and it didn't change anything.

Hm…it may be a hardware problem.
