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.

Wifi sucks :(

Hi all,
I just got my device, and still thinking whether to send it back in 7 days. My main complain is the wifi. I have never seen more than 2 bars (out of 4) signal strength, even when sitting 2 meters from the router. Moreover it always drops the connection. I realized it when I tried to use IE for browsing, since that doesn't tolerate it and I keep getting the connection lost messages. Seems that Opera can live with it, but I see when the connection dropped during the page load. Youtube watcher also cannot manage to download videos when the signal is dropped.
The Tx/Rx rate also changes chaotically from 1Mb/1Mb to 54Mb/36Mb.
Before you ask: the Power Mode of wifi is set to "Best Performance", since this is the only way it is usable.
Anybody else with similar experiences?
Any solution?
I really appreciate any help, I would like to keep it!

I have no problems what-so-ever with the wifi on my D2...
It runs very well, in all applications that can use it.
- and I have full signal when I am within 5 meters of the router.
I haven't changed any settings on the device, and the router is running on WPA2-PSK at a channel not used by any of my neighbours.
Maybe you have many wireless networks in your area?

Hi,
I have more or less your problems (I opened a thead about it the day I unpacked my D2 but wasn't really condiderated). Here's my condition: I have 3 HTC devices...Artemis-->regular functioning (balanced power), TytnII-->Power Performance MUST be set to high performance, Topaz..well I could connect with balanced power but since I upgraded radio I have to keep it set to best performance, otherwise I would get "fake" connections (connection established but no data taffic). I don't really bother to have to set it like that because the connection is dam fast, which compensates the higher power consumpion.But beside this, I must say that my router is not very friendly with my D2,e.g. when I don't get a connection,I restart it and it works (this must have to do with DCHP service). I have much less trouble connecting alsewhere. So ,what to say? Try to change radio...Do you have other wireless devices working regularly in the same area?Do you have an original rom?You could also try to change wifi channel..would be happy to help

Hi,
Thank you for the answer. I have original ROM, just checked the radio, it is: 3.43.25.19. I didn't experience "fake connections" when it is connected, it is so .
I cannot change the wifi channel, the same router is used by others. However it cannot be the cause of my issues since my notebook's network works fine on the same router.
Changing the radio... seems a good idea. It is my very first smart device, I even thought that this version number was for the hardware, not the software . I will find out how to do it, maybe give it a try. Hope it is an officially supported action .

Hi Lamsebamsen,
The TD2 sees 4 wifi networks, my notebook sees 8. Is it many or not? I think the 4 which the TD doesn't see is many .

I'm afraid not, as you would have to HardSPL your device first. There would still a way to get back to your original configuration but I don't know if you are prone to do so, that depends on how much responsability you can take on your device (is it from work or..). Another thing to try is to manually configurate your connection (e.g. assign D2 always the same IP, but watchout for network collisions!router should be set aswell)

Cannot connect to WEP secured network

I have done about everything. I can connect to my Android phone (using tether), my house, other open networks PERFECTLY, but unfortunately my gym uses a WEP network and I cannot get my tablet to connect to their network.
I have rebooted, forgot the network and set it up again (a million times) I have done EVERYTHING. My Android phone can connect to the gym network perfectly. Any suggestions?

Anyone have any suggestions? Does anyone connect to a WEP secured network and know that this works?

I had the same problem and found out the solution changing some values in the set up router.
Sent from my X10i using XDA App

I'm connected to our home browser which uses WEP. I think it's a matter of settings/wireless and networks/Wi-Fi settings/add wi-fi network. Once you are in the 'add' page, it asks about security, you should be able to input the data.

I have had same problems, honeycomb handles WPA and WPA2 enterprise networks weird compared to gingerbread. I have had problems with connections too. Try to use the "wifi advanced config editor" and make sure settings are correct for that network (after you attempt to connect to it in settings app). I hope google fixed this problem in ICS or i will be furious. Most of these kind of bugs are laziness on coders or just people who missed lines of code and then don't want to release an update (or wait till next update release rather than a hotfix).

So just to make sure I understand...
Basically the way I originally connected was that I let the tablet scan for networks, and it found the gym network. Once it found the gym network, I selected it and entered the password. I left the proxy and DHCP settings alone and pressed connect, and cannot get it to connect.
What you are suggesting that I do is delete the network, and add the network MANUALLY (where I input securtiy, SSID, passcode, etc.).. Is that right?

So I installed the Advanced Wifi tool, to no avail.
Here is the funny thing. I have a Samsung Epic 4G phone which uses Gingerbread, and it connects to the WEP just fine. I installed the Advanced Wifi on there as well, and went through the settings that were autoconfigured for the gym. Each setting matched my tablet perfectly, yet my tablet cannot pull an IP address, but my phone can.

I'm having the same issue. Thought it was the tab, just received replacement and still a No Go! Every other device in my house connects to this network. And the Gtab also connected perfectly until recently... no clue what to do now.

[Q] 4.2.1 unsupported wi-fi?

I realized that my University's wifi somehow does not support 4.2.1
I've asked them about it, and they said 4.2's kernel might be different and it might not recognize the wifi.
What can i do about that without downgrading? (My device is rooted.)
Thanks.

Perhaps you should say a few words about your University WiFi. Same goes for what you have done to your N7 (as you stated that it is rooted). Maybe you could mention whether or not you personally had it working with a 4.1.x-derived ROM on the phone - reading between the lines it sounds like that might be the case, but it isn't clearly stated.
"Does not support" is not very descriptive.
First - does the WiFi scan on the N7 display the network? (e.g. the N7 does not support Ad-Hoc networks, so they won't even show up in the first place)
What details can you provide about the WiFi network?
- Ad-hoc or Infrastructure mode?
- is WEP/WPA/WPA2 in use?
- if Y to above question, how is key distribution performed?
Are there any other relevant symptoms, such as the N7 connecting, but then fails to get an IP address - or gets an IP, but still acts as if not connected?
If you are convinced that it is in fact a 4.1.x vs. 4.2.x issue, could you not just install a 4.1.x-derived ROM?

Note also that the n7 does not support WiFi N band. Make sure the university provides G support.

The N7 absolutely supports 802.11 b/g/n. Take a look at the tech specs in Play store.

I know that, Wi-Fi works with Galaxy S 3 having 4.1.1
And the setting used to access Wi-Fi are as follows:
Security: 802.1x EAP
EAP Method: PEAP
Phase 2 Authentication: MSCHAPV2
... And I put-in my username and password in the followings.
I tried to connect, it shows the signal much weaker then it actually is, then it tried to connect, but just fails...

That's all well and good, but it doesn't necessarily mean that 4.1.x vs. 4.2.x is the cause of things. Different hardware, different OS, and presumably different WiFi radio hardware and firmware. Could be any of those things, the OS being one of them.

Association and Authentication to a WiFi AP have lots of moving parts. It is possible that the problem is with either of them. (My WAG would be the authentication process) Without a super-geek that can help you with wireless sniffing (to see if the fault location can be inferred), or your campus IT help desk being able to look at authentication logs, you don't really have much recourse but to:
- do something drastic (e.g. install new ROMs)
- experiment with the settings in the WiFi "Add network" page, and look to see if you get any meaningful or diagnostic messages in the system logs. I tried it just now, but I don't have an 802.1x AP available to test (a failed PW, for instance) with to see if anything diagnostic shows up in logcat. Is it possible that it is just a bad password entry? (I have had problems when I cut and paste in android with various apps inserting a leading space ahead of the paste).
The 4.1.2 factory image for the WiFi N7 (grouper) is still available from Google - I think the form in which they provide it to you needs to be flashed using fastboot though, and managing that seems to cause newbs trouble. You might want to just find an older ROM which is based on 4.1.x and try it to see if it fits your hypothesis. (If you fool with a factory ROM install, make sure you have backups of EVERYTHING first).
Good luck

I have taken my nexus 7 to IT they looked into it and they said its possibly that it not compatible with 4.2.1
I guess downgrading to 4.1.2 might do trick, but I also don't want to leave the awesome features of 4.2.1
I guess I will firstly try different kernels and see if they change anything.

This thread contains reports of problems with both 4.1.x and 4.2.x N7's
I suspect that just reflects a diversity of different wireless networks; but anyway - see the logcat entries with "I/wpa_supplicant" in them? Your tablet (on 4.2.1 or whatever) might have similar things in it that gives clues as to where the errors occur.
You can get logcats with adb - or failing that, there are free market apps you can get which will dump the logcat to a file of your chosing.
Good luck

Thanks I will take a look at those.

Miss-statement on my part earlier. Nexus 7 does support 802.1n operation - but only in the 2.4ghz band. 5ghz is not supported. My router supports both - and the faster ssids are not even visible on the Nexus 7.

Is that all about hardware, or is there a software wise solution to it?

802.11n specifies channel bonding techniques as well as optional use of the 5 Ghz radio band.
So, marketers can safely say "Wifi N" or some such - as long as the hardware/software can do channel bonding (but possibly not operate in the 5 Ghz band).
Here's Asus N7 Spec Page, as you see they do not mention 5Ghz Wifi.
My thinking is that if the hardware had it, it would also show up proudly in the specs.
A to the Q: hardware.
It now occurs to me that Zhoene earlier had said

A university setting probably would be a WDS (Wireless Distribution System) with many AP's. Possibly Zhoene was sitting close to a 5Ghz-only AP, and "seeing" a multi-band AP at a good distance away? Sure would be consistent with rmm200's observations on his/her router.
Also, I see reports of 5 Ghz service achieved on Galaxy S3 (Zhoene prev mentioned)
Perhaps this is exactly a 5Ghz AP vs. Nexus 7 issue.
And, oh crap after all this writing I did a search
http://forum.xda-developers.com/showthread.php?t=1777431&highlight=5ghz+802+11n&page=3
Zhoene you could ask your campus IT if there are any A/B/G- or B/G-only APs in their network & see if you can connect at those locations. If it was something weird like Beacons only in 5Ghz-band channels (I think that would violate the IEEE specs), then you could have been trying to connect to very remote APs - all the while getting clobbered by other devices sitting nearby doing 802.11n in the 2.4Ghz band, but also the nearby AP as well if it was operating in multi-band mode.

Thanks a lot for all the information, I'll try to find out what the problem really is using those informations.

Some of this talk of networking is over my head, but what I would try is flashing a 4.1.2 ROM/image and seeing if that fixes it. 4.1.1 had a bug that prevented the Nexus 7 from connecting to WPA-Enterprise networks, which is what my university uses (I know because my Kindle can't connect to it). 4.1.2 fixed this, and my Nexus 7 (on 4.1.2) can connect to my university's network. I have been rejecting the update to 4.2.1 after hearing about issues, so I don't know if it works with 4.2.1.

NexusHD2-JellyBean-CM10 V1.4a - Networking issue

Hi
I just installed the NexusHD2 ROM today, and I experienced a bug/issue with this ROM.
The problem is that my wireless network is hidden (doesn't broadcast SSID and doesn't show up on list of available networks) and therefore no devices will see that it's there, unless they know it's there. I did have the SENSATION XL v3.0 Android 2.3.5 on the device before and that one did not have the problem. Before that I had some PACman JellyBean ROM, which also didn't have that issue.
My HTC One X with stock HTC 4.1.1 ROM also registreres my hidden network without any problems.
Now in order to get connected to my network, I need to tell the OS (doesn't matter if it's Android, WP, iOS, Windows, OS X, Linux) that it's there, and also tell the type of password-encryption and what the password is. This proces is just the same on every single ROM I used, but only difference is that the NexusHD2 JB ROM doesn't recognize the network when it is hidden. If I then go to the setup of my Wireless router and turn off the hidden network, so that anyone, within range of the wireless router, can see it, then it also is recognized by the HD2 and it automatically connects. When I then hide the network again, it stays connected, until I reboot the phone or until it turns of Wi-Fi to lower power-consumption. When it then tries to reconnect, I have the issue again, where it tells my that the network is out of range/not available.
Does anyone else have this issue, or does anyone know how to fix it, without having to change the configuration of my router.
I have the HTC HD2 EU 512MB Version

Just go to settings and add the network manually. The plus sign at the bottom of screen!

I use the same setup - hidden network - without problems. Not sure what the problem is but I would try a lower channel number and/or set a different encryption method on the router to see if one might make a difference.

Appreciation is a wonderful thing. It makes what is excellent in others belong to us as well.
