HD2 WiFi problem **HELP**

Please help, ive had my hd2 for a few days now and have had nothing but problems, might just give it back!
It picks up my home router but simplify wont connect, it just displays a small rotating circle likes it working but nothings happening.
When i remove the settings and retype the key code it keeps saying incorrect code but it isnt,
Anyone any ideas, can i some how reset the wifi settings, its taken me a few days to customize the phone so i dont really want to do a hardwear reset. Ive already a software restset.
Bloody htc!

What protocal are you using on your router? WPA, WEP?
Oh if your using an older Belkin router, I know of about 3-4 models that used to have trouble with WinMo, an update Router flash fixes it though.
Give us some more info on your router etc and Im sure we can help though

Sure your using the right password/key? if it says its wrongs it is probably wrong lol. Maybe try changing it to a more basic password as a test? like "password" and see if it can get connect.

Hi
Calm down. Give some information about your router and the type of security You use.
try these
1. Reset the router once
2. If you use MAc access list on the router then add your device's MAC to the list.
3. If you use N router then in the settings untick N mode protection.
Give more details about the third party software on the hd2 using radios (eg: tomtom, igo,gpstuner like these)
Good luck

HI guys thanks for helping out.
Obvious first - yes the key code is correct i use it on my laptop and iphone.
security mode says WAP-PSK/WPA2-PSK. Its a siemens ive been on the ip server addres and cant see any issues, im on my laptop using the wifi now and its working perfet.
Ive tried everything, changing passwords, settings both on the router and on the phone.
The hd2 is full of really stupid bugs!

Try to hardreset the PPC.
If it won't work, try to update your ROM to the latest available.
If it doesn't want to work, then try to connect to another WiFi without password and see the connection is successful.
If it works with an unprotected WiFi, try to connect to a different router but with protected WiFi.
If it works, then there is a problem with your router and I suggest to update your router's firmware.

funny wifi
the problem wit my hd2 is most of the time it shows wifi connected but i cant surf the internet and sometimes out of the blues it connects to the internet,cant figure out wats happening....

HI kholk, thanks for the help, ill work my way through it and hopefully get it sorted!

Have you found the solution? I can help you my friend i had the same situation

I tried to connect yesterday my hd2 with my router. First it wasnt working aswell. Then i set the next things. Channel 9 (was auto), Encryption AES (was tkip and AES). Network mode is Mixed. Further have you installed Mac Filter? I installed this also. So if i have a connection thats it. I must fill in my macadres from my phone for i get fully connected.

Hi guys thanks all for you help call HTC UK support and their amazing advice was to do a full hard reset!
I really am having a lot of problems with this phone and i cant understand why their have been so many issues?!

Hi guys,
I have the same problem- HD2 shows it is connected, but no access to Internet(other- laptop, SE990 phone is connected and working OK)
For not to write about all, now situation is:
1. On router wrt54g2 temporary disabled wireless security, only mac filtering is on(laptop mac, SE mac, HD2 mac is allowed), router firmware is up to date
2.HD2 is like new after hard reset, no settings is done for connection to home network. HD2 wifi is on, looking for access points and connecting to only one available open network in my area- to my home network and shows it is connected but no access to Internet.
3. In router I can see all connected clients by mac. All 3(lap, SE, HD2) are connected. I use Network Magic software too but it is showing only my laptop and desktop are connected. SE is not connected according NM, but it is working OK.
P.S.
Do not know what else can help you in my problem(maybe some other router setting, but as other devices are connected without problems so maybe it is not important for now)
So only my HD2 can not access WWW
Can You guys help somehow please

I've got a similar problem with an HD2 over here. Wifi does switch on, but it just won't connect to my router. The cirkel that is supposed to show when connecting to a network doesn't show either. I'm using WPA2-AES security, and yes, i did use the proper network key. I haven't tried connecting to other networks/using an alternative encryption method because a lot of other devices will then have to be reconfigured and it's not my own place. My Touch HD and 2 laptop connect to the network without any problems. The only solution I came across until now is doing a hard reset, which I would rather not do... I'm using a stock dutch rom (V1.43). Is it possible that upgrading to the newer 1.48 will solve this problem?

Have you tried removing the wireless security password and trying again? Test to see if maybe you are indeed typing in the password wrong.
Also check your exception list on your router, it might be blocking any other devices coming in.

I have the same problem.. Get the spinning loading circle and thats it.. But if i turn my belkin wires g router running wpa2 off then straight back on again the phone connects fine. But if i then leave my house or disconnect from the network then try and reconnect it wont and have to do the same process again. Luckily im also running a speedtouch 585 modem router which the phone connects fine to.

hey maybe it takes only a WEP key and not WPA as most people have. this is certainly the case as mentioned in the Wifi router article below -
http://www.mobilityminded.com/5438/wi-fi-router-on-htc-hd2-application-overview

Again me
It seems that it is problem with my router. HD2 was able to connect to open wireless a.p. in my town and all sow to my friends router which is using WPA security. So my linksys is not compatible, or i will try some other settings on it, but as other router clients have no problems, i am loosing my hope to have my HD2 connected at home unless i change router. But then another problem- which router will be compatible with all my devices in prise range of 100$
And replying to blackheart2925 my friend is using wpa not wep, i do not know other settings on his router but it is not security problem.
One thing is strange for my HD2 shows it is connected, router shows mac of HD2 among connected clients, but only HD2 do not have access to internet

how are you connected to internet is it router which dials to isp or you have made a broadband dial up on your desk top ...
if you have dial up shortcut on desktop then you can not use internet via hd then change setting in router
better way is hard reset router and then reconnect hopefully it will solve your issue ..........

Router "dials" to my isp and share internet for all connected devices...
Yes, i am going to hard resset my router, but have not much hope i sucsess

PROB:
If your HD2 connects to router but you cannot enter any web site, do this:
SOLUTION:
enter your www router settings - wireless - access control - MAC Address Filtering Table ->>>>> add your HD2 MAC adress
enter your www router settings - firewall - access control ->>>>> add your HD2 MAC adress
so, you have to add your MAC adress of HD2 into router TWO TIMES into TWO PLACES!
I had the same problem and..... solved

[Q] wifi problem with 2.1

wifi problem with 2.1 seem the same as x10. Cutting wirles on week signal. Any other have the same problem?
youtube.com/watch?v=wT3gruYWWVo
blog.se-nse.net/xperia-x10-wifi-bug-cause-found/
The bug Im pertaining is that the connection fail for seemingly no reason, even whil in use, then reconnect and operate normally after 10-20 seconds or so.
Sent from my E15i using XDA App

I had this problem on 1.6 and still have it on 2.1.
I don't get it though. My phone behaves better with some wireless hotspots than others.

Moved to general.

That isnt bug.
Phone says that router isnt in range because mobile cant find it in first second.
PS I dont have that problem.

The problem is that the ruter is in range and the connection is at 30% then I try to download somting from net or retrive somting from dropbox and the wifi connection broke for 2-5 sec. and then it connect again.. all day long.
I try to change SIDD, chanel and the problem is the same. The problem is that wifi shout down and restarts.

Repair your softwer.

software is 2.1 rus. flashed 4 time and the problem persist. now im back to 1.6 (rooted) and waiting for the wifi to go mad ;-)

can help for you a new (not from original site) firmware in your router (dd-wrt) - serch HERE

try changing security mode on your routter from wep to wap and vice versa it might help

I'm having problem with the wifi too. Icon is there, but connection is lost. I have to refresh the page multiple times before wifi starts to work again. I configured my wifi setting to never...It's making me mad because I didn't have this problem on 1.6...
And it happens in close range to the router with full signal. I hear that lots of people have this kind of problem...

Yup, I am having it. I can be right next to my wifi hotspot, and it still drops.
But like I said, other routers seem to work better with my phone than others, strangely.

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...

[Q] Upgraded MS2 Froyo to Gingerbread, now Mobile Hotspot doesn't work any more?

Has anyone got Mobile Hotspot to work on their MS2 after the upgrade to Gingerbread?
I've been having problems - Tte MS2 properly assigns an IP address to PCs that try to connect to it over WiFi, but the connection doesn't seem to go past my MS2 to the Internet. Same thing whether USB or WiFi.
I'm on T-mobile on the USA - could that have something to do with it, some kind of authentication is being performed now (that wasn't being performed on Froyo?)

I had this problem too.
Now I use the app "barnacle wifi tether" and it works fine.

Thanks for the suggestion. If I root my phone I'll consider that option. Has anyone found any other fixes? I tried playing with the APN settings as suggested by some online, but it doesn't seem to help.

Usb sharing is f*d up - dnsmasq does not launches properly and phone gives no IP in response to dhcp req from pc. I don't remember, if setting an IP and gw manually solves the problem.
However launching _both_ sharing method at once helped. DHCP worked fine. Maybe launching wifi hotspot alone generates similar problem?

Did a factory reset and now Mobile Hotspot works!
Haven't tried USB tethering yet, will report back when I do.

Great! I also had this problem and this tip helped me.

Mobile Hotspot works but haven't got USB tethering to work properly yet. The computer can get an IP address from the phone, but no connection through to the Internet. This is after the factory reset.

Same with me here.. Already did FR but still no go..

Old thread I know but anyone sorted this yet, as its doing my head in, I even changed to a tethering plan in case i was being blocked.
Barnacle Tether doesn't work either same symptoms also says DHCP:Could not bind to DHCP port Address already in use

Could it be your carrier blocking 3G tethering?

Hi
3G tethering is not blocked by carrier as I am on a tethering plan and have spent a long time on the phone to an Indian call centre to sort it.
But joy of joys after trying everything I could think of including re-flashing and wiping all data etc. I have managed to get it working using wifi tether for root user

[Q] Problems connecting to wifi network: looping "obtaining IP address"

There appears to be a problem with new versions of Android and old routers. Many people have reported the "obtaining IP address" loop problem.
Let me explain. I use the leisure facilities in a local hotel. It has a public (open) wifi network. I believe it uses an old router. My Galaxy S2 (Gingerbread) and AsusTransformer (ICS) both connected to this network without problems. I recently replaced the S2 with an S3 (ICS) and my Transformer with a Nexus 7 (Jellybean). Neither of my new devices connect to this network. I have had the same problem in a local cafe.
I have researched this problem. It is not uncommon. It appears to be caused by an odd mix of hardware (router and wifi chipset) and software (later versions of Android). If you are unlucky (like me and some others) you will be unable to connect to some networks.
The solution is to use static IP addressing (since your device is unable to obtain a dynamic IP address). This will allow your device to connect to the network -- but you need to know the correct settings (for static IP addressing) before you can actually use the network.
This problem has been reported by many people. Does anyone know if there is a fix or a workaround?
The only one I can think of it to get hold of a device that does connect to this network and copy the (static IP) settings. But this would only solve it for one location meaning that I will run into it again the next time I try to connect to a network with old hardware.

Sometimes when I get that problem it's due to IP address conflicts on the Windows 7 computers.
I go to the computer and:
http://helpdeskgeek.com/networking/release-and-renew-an-ip-address/
Otherwise I just pull the router out and refresh it, should work for another few weeks or so.

I don't have access to the PC. It is owned by the hotel. I need a solution that I can apply client (Nexus) side.

Solution
I found a solution. I asked the guy to reset the router and both my Nexus and S3 immediately connected. Someone advised me to do this. I have no idea why it worked. Not really a solution since i cant go round cafes asking people to reset their routers for me.
Is there a way to find out IP, DNS, gateway etc values on Nexus when they are dynamically assigned?

I sometimes have this Problem when starting my accesspoint after enabeling wifi on my N7.
I have to reboot my N7 in that case to get an IP.

Happened to me quite a few times when I went out with it to a restaurant or something. It just loops and loops.

My Nexus (and S3) now connect to the hotel network every time now. So it looks like you only need to ask the owned to reset his router once.

Resetting the modem solves the problem if you don't make any change to the router settings. I don't understand why the hell google is not solving the problem yet...
many users are found to face the same problem..
eve I can connect with my Nokia E72 but not with my N7...
I can get the IP from my cell phone. But come on, what's the point of doing so?? Are you gonna assign the IP for each and every WiFi you connect?? Or if the IP changes everyday??

Static ip won't help, yes you can connect to wifi, but cannot get connection to internet. This is a bug of android, and ITs in Princeton univ. had some investigation. 412 should have fixed it

I just started having a similar problem. I have a samsung galaxy tab with Sprint. I've had it for a year and this is the first time I've had this trouble.
The only difference is, I cannot connect to any wifi network at all. It keeps hanging on "obtaining IP address" and then disconnects. It doesn't matter if it's my home wifi or school or free wifi in a restaurant.
The only possible connection I can make is that I downloaded Lookout to check it out as a possible security app, I have since uninstalled it but that did not fix my problem.
Continuing to research this but any ideas on how to fix this would be fantastic.

I'm having this problem on my HTC One S. It happened yesterday without warning and it's really annoying. I went to a nearby cafe and the wifi worked perfectly, so it's something wrong here.
Static IP solution connects to me to the network but I can't actually use the internet, so I'm stumped.

i'm getting the same error with AOKP 4.2.2, and also know people with stock 4.2.2 with it.
the only way i found to fix it is to reboot the phone..... and wait for it to happen again and reboot it again
i cannot use static IP since in my university (and some other public places) it is not possible to connect it like that :S
