HTC Tytn Wifi Drop Connection

Hi,
I experienced some problems wih my HTC Tytn (R 1.03.03.10).
At home I use a wifi connection with WEP 128 bits authentication.
The wifi connection procedure goes ok every time (with regular Ip adderess assigned).
After connection I can normally surf with IE (or use other other applications as MSN) but only for few seconds. In fact after few second it is not possible to surf anymore although it seems to be connected to wifi AP with regular IP address assigned (the icon and the specific menu say me that). After other few seconds It is possible to surf again, and so on..... The connection seems to drop and raise randomly.
I tried to modify some settings (eg. Power save mode) but with any result.
Thank you in advance to anyone could help me to solve this problem.

Couple of routine things you may already have done/tried/checked:
Try best performance setting in the "power mode" in Connections>wireless LAN.
And the range of the wifi is only around 10 to 15 metres are you within this without large obstructions?
Could also set a fixed IP address.
Mike

Thank you Mike,
I've already tried to set power performance to "power mode" and I performed my test near the (2-3 meters) without any obstructions.
Later I'll try to configure a static IP address and/or to deactivate WEP authentication. I could try a mac address based access too, instead of WEP.
I'll inform you later !!!!

Ok - can't see problem with WEP though - I use that with 128 encryption without problems.

I'm facing the exact same problems with my home network.
Connection up and down.
At office network never faced such a behavior.
Since I realize I'm not alone with this problem I'll try to investigate it more.

I've had the same problems at both my home and office. I use WPA-PSK w/ TKIP for security on both devices, though each of the access points are of different manufacturers (home is a Linksys, office is a Cisco 1231). Both routers run compatibility modes for 802.11b backwards compatibility and thats the only thing I can think of that is common to both. My WiFi connection usually associates with the AP but always ends up with a 169.254.x.x IP and the only thing HTC has been able to tell me is that the 8525 only supports 40 bit encryption (which is blantently wrong if it's even detecting the WPA-PSK). Has anyone come up with a solution or even seen the same problem? If needed I can post logs from the Cisco AP that show what occurs when the 8525 tries to associate.

Just out of curiosity, when you say backwards compatibility do you mean the router is capable of "g" rather than "b". If so have you tried "g".
Mike

I m having the same problem. I connect to Wifi, i can surf a couple of pages and then i just cannot browse anymore. I have to turn off wifi and then turn on wifi to continue browsing from where I was at.
Any help on this would be greatly appreciated

When I say compatibility it means that the radio on the AP can fall back to "b" speeds if necessary. And no, I haven't switched them to only "g" mode as that should not be necessary if the wifi implementation on the Hermes is up to spec.

Same problem here?
I have a Cisco N router, so does that mean its useless for WIFI for my phone?
I also tried to change the settings to Best Performance but it wont allow me to change them? Any suggestions please anyone would be greatly appreciated please? Must I have only a G router? And whats the SSID in current configurations? Should I enter the Routers IP? And where should
I enter it please?

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

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

thanks in advance!

thanks!

ok, so since no one tried to help me here, i tried every single thing on my router and it seems that the phone can't handle b+g standards, so i switched to g allone and now i'm able to connect. i hope this will help someone else too.

Nice tip
Hey man,i guess no one had the problem or didnt know what to do,anyway i had a differrent problem,when i was close to my router (no more than 8 meters) my phone connected normaly to the wifi,but once i was in my room which is further away from the router the phone wouldnt connect although it showed the wifi router signal had two bars,i tried your method in switching to g only and it worked ,now i connect to my wifi with no problem,thx for the tip ,hope they fix the issue in mango,cheers.

I have the same problem with my wifi router.
My phone is HTC 7 Throphy.
I have to reset my router every time my phone needs to connect to it.
My router is configured for DHCP.
I noticed that if there is a wireless device connected to my wifi network,
my phone gives that error and cannot connect.
If I try to connect to a wifi network which is secured with a password,
I always get 'Incorrect password' message.
I try reseting my phone with no effect.
I'm still looking for a solution.

no problem man.
it seems that there are many troubles with wifi on windows phone 7 and many users are complaining. i hope too that mango will fix most of those issues. mango will bring possibility to connect to hidden network.
for other users posting on this topic, i suggest that they try switching to g standard only, becose i too had this incorect password message allways poping up before the switching. it can be done in the router web configuration interface. u get in usualiy by typing 192.168.1.1 in your adress bar.

My router is on g standart only but I still get that error.

well, if you know what you'r doing, you could try different configurations in your router. play with the settings and see if it will work, but again, only if you'r sure you won't screw up anything.

I found a fix.
In my router settings I changed the Chanel from 6 to 10.
I think the problem is that I have too many wireless devices in a small room.

you lucky bastards with wifi connectivity.. i have a pppoe account on my wifi and there is no way for me to connect to it whatsoever.

if you have access to your router settings, you can change briged to routed connection.

for some reason, i can't access router! i tried contacting my ISP, did not want to die waiting for an answer.
but i remember trying to do that before, and not knowing how.
Could you post a link with the instructions, zemljak?

I have this intermittent connection on a netgear wireless router too, its set to use dhcp, and only fix is a reboot of the router.
I think the phone is storing an ip (dhcp assigned) which when you reconnect to your wifi may have been re-assigned (ip lease) to a.n.other device in the meantime.
So, lets say on Monday I obtained 192.168.0.2
didnt access the wifi for a day or so
lease expires (router)
a.n.other device connects, e.g. iPad, obtained 192.168.0.2 via dhcp
then you try and use your wifi on your phone and it doesnt connect.....
so I think it might be storing the ip address, rather than checking for a new one each time it connects, or something similar.

Over a half year I had the same problem. But now I fixed it, by simply change the wlan-key, because in my old key I had letters like ä, ö, ü. That didn´t work. May be this works for you.

FIX!

I started having the same problem with the phone prompting me that i had the incorrect password. I changed the channel in my router and now my Surround is connecting without hessitation! Thanks!

Hi,
I have Nokia Lumia 800 with Windows Phone 7.5 and also have problems with my home wifi connection. Firstly I had an old pentagram router and couldn't to connect with it, I tried WPA, WPA 2, WEP, WPA 2 mixed or even no security, always had the same problem, shows "network don't respond".
The phone itself connects to other networks, but not my home network.
I thought that it was problem with my router (but every other device had no problems with conenction, ipad, galaxy s, laptops or even TV), so I took another router (techniklab) and I have the same problem.
On both routers in "active clients" I saw the phone when it was trying to connect, logs looks like:
Code:
Aug 20 22:13:31 wlan0: WPA2-AES PSK authentication in progress...
Aug 20 22:13:31 wlan0: A wireless client is associated - 50:2D:1D:E2:8A:87
Aug 20 22:13:31 wlan0: Open and authenticated
Aug 20 22:13:53 wlan0: A wireless client is disassociated - 50:2D:1D:E2:8A:87
Windows on my phone is up to date, router firmware also.
I can add that from couple of days I have Windows 8 (on PC) and it also cannot connect to my router, could it be some problems in new microsoft windows??
Any suggestions?
