Wlan Problem, can´t connect to former AP - Acer Iconia A500

Guys,
I had an issue connecting to my day to day wlan AP. I had this issue on serveral Android devices now. Android just does not find the AP you connected to the last week days moant etc...but you find all other kinds of access point and you can connect to others and so on.
Here is how i fixed it, login to your Wifi router and just change the channel by one number, only remark is stay below channel 11.
this is not new found it serveral times on the web. no factory reset needed.
cheers

Can't connect using WiFi on my MDA Vario 2

Hi there,
My WIFI connection worked fine with a Belkin router I had. After upgrading to a 'Netgear Next Wireless ADLS2+ Modem (router)', I cant seem to lock onto the router.
I type in the WEP Key, but then the arrows of the indicator on the top continue moving showing that no connection has been established.
I am not as good as I would like to be with networking, so I need easy step-by-step advise with how I can set up a connection.
Please help.
Many thanks.

Anyone?
well since it worked before maybe the question should be posted in the Netgear forum
i would at first upgrade the firmware of the router if possible
Hi
I've not long had my Vario 2 and I had the same problem, it just refused to connect. I looked in the active Station List in my routers config page but there was no sign of my vario's MAC. I thought maybe the wifi was busted so I took it to work and connected fine. Back to my router then, eventually it appeared in the station list but was being reported as failing the WPA authentication. I must have put that key in I don't know how many times before it finally let me in. I don't know how it happenned but I just sat there repeatedly entering the key and refreshing router config screen.
I suggest you try connecting to another wifi network to test your device. Try connecting to yours with security off, then switch it back on.
I just had to seemingly bully my router into letting me connect, but after some time (several sessions over a few days) it did.

How I solved Wifi problem

Lately I have been reading many post related to Wifi problems in the HD. I had the same. Even I was very near my router I couldn't connect to the net and the signal was very weak.
So I entered my router configuration and I found a solution.
Before, for security options I had: WPA-PSK [TKIP] then I changed to WPA2-PSK [AES] (of course you also have to change your HD connection configuratoin), and now it works great¡¡¡¡
Now I have all the bars for the signal and I can connect very easily.
Hope it works for other people
I have a similar WiFi connectivity problem, but after reading of the poor service provided by most vendors and HTC itself, I will try to gather some more experience with the problem before I contact HTC or my vendor, and hopefully find a solution. Bellow is my experience so far:
I own an HTC Touch HD since January and have a similar problem, only it surfaced last week. Before I had only used the WiFi connectivity briefly. The problems started after I installed an AP on my house expressively for the new PDA. The node is fully open and set to B/G/N protocols.
After a couple days of medium (couple hours per day) use the WiFi connection suddenly quit, the device would try to connect (the top bar showing the WiFi connection animation continuously) and after a few moments gave up with a dialog box stating the current network settings were wrong (even thou they worked fine a few hours earlier).
I tried several hot and cold resets, but only solved the problem after flashing a new ROM; even then the same symptoms reappeared after a couple of days of regular use. Again no re-setting would cure the problem, and now not even flashing the ROM again would work. Nonetheless, some hours latter the WiFi would connect perfectly with the same nodes it refused to before, and in very short time.
I have witnessed this cycle twice and have yet not been able to find a trigger for it, but will keep my eyes open for any tell tale signs, and post any findings here.
I could add to the above mentioned problems.
i got a new hd just few days back.
The wifi worked great. But now it doesnt.
I have disabled wifi, so can start it whenever i require.
I click on wifi button to enable it.
Then open opera, try any website.
it will open fine.
For instance say my email at gmail.com
Now after that if i try to open anysites or even continue with my mail, it shows error saying connection not available.
One of the workaround is to go back to toggele wifi off and switched it on.
Not sure if anyone faces a similar issue.
I's been about a week since my last post and I have already witnessed a couple of cycles of WiFi connecting perfectly and then not connecting at all.
No matter the settings I try after it decides not to connect, it won't. Even to nodes it had connected perfectly and fast jus minutes before.
I thought re-flashing might help but so far has proven ineffective. Once I thought some part of the non-volitile memory was causing the problem since after I cleared the memory I could connect for a while.
Any thoughts anyone?
Same problems here.
For the last hour I have been reading 10ths of threads here concerning WiFi problems.
My HD's WiFi worked fine on my home and outside for about 2 months. Now it doesn't. It reports connection, but no program can use the internet. At best, it seems to be able to exchange some Kbytes the for just a few seconds after a connection is established. Then nothing. Connected but unusable.
Tried everything Internet/My Work/My ISP, WAP enabled/disabled, soft/hard reset, everything.
When connected through ActiveSync everything works fine, all programs see internet.
Has anybody taken their HD to the service? Has any HTC service worldwide identified the problem as hardware and solved it by replacing something?

I have just encountered a similar problem, but already used wpa/wpa2 with aes. Have tried a hard reset with no joy. My old HTC Touch has no probs connecting via wifi nor does my laptop so I would surmise that the prob is with the HD and not the router.
I am going to try flashing with the latest version of Duttys 6.1 rom and see what gives.
Edit: Tried flashing with new rom with no success. Take a look at this post.
http://forum.xda-developers.com/showpost.php?p=3769339&postcount=7
There are a couple of files to download but i only used the second ie this one.
http://forum.xda-developers.com/showpost.php?p=1363759&postcount=2
Now no problems and can connect via wifi no probs, ip address assigned by dhcp.
Try to go into WiFi settings and move the power slider to max performance. I need to do it here to access my router. This happened also with my HTC TyTN II, with any recent radio firmware. The original WM 6.0 ROM and it's radio work fine in low power mode, but the new ones appear connected but are always at 1 Mbps and there's no traffic until you move the slider to performance mode.
You go into WiFi settings and you configure manual IP and DNS so as router.
DNS is important.
Whit manual configuration, Wifi work always.
(sorry for my english)

This is not a solution. I didn 't buy the device to be able to connect to my home WiFi only. What about public hotspots? Or hotels? Or whatever outside your home?

Can't connect to WiFi using Touch HD

Hi everyone.
First off, I know there are a million and one other threads.. believe me.. I have searched!
Basically my phone won't connect to my network. It was working fine earlier today. I've tried changing all the security settings in my router (turning off encryption for example). I've tried soft resetting and hard resetting the phone.
Nothing seems to be working. It finds the network fine, but it just says 'Connecting' then goes to 'Available' but it won't use the wifi connection.
Any ideas?
Thanks!
Have you tried connecting your device using a friends wifi router to see if this connect you
Nope. I forgot to add that I will try connecting to work's WiFi tomorrow!
Anything to try in the mean time?
Try these:
1) disable frame bursting
2) disable big packets and other methods of wifi speeding
3) force 11b
4) use WPA-PSK TKIP only
5) check if you have MAC or other access filtering
than let us know

1) Can't see any settings under my router.
2) Tried disabling gnitro (Belkin router), no difference.
3) No difference
4) Already on that.
5) Turned off.
It's so odd. Works fine with an N95.
I don't think it's anything to do with my router because like I said it worked fine earlier on in the day then suddenly stopped. The router settings hadn't changed.
Edit: I've tried turning the router security off altogether also. I really don't feel it's an issue with my router.
Tested the phone at work. It works fine.. so I don't have a clue why it's not working at home? Surely the router can't be incompatible with the phone.. especially considering it worked at one point.
Very weird! I got fed up with my router so decided to restore the factory defaults and start from scratch.. worked straight away! So I restored the settings back to exactly how they were before (using a backup file I made).. and it worked!
Just posting incase it happens to anyone else anyway.

Maybe uve tried this already but could be the fact that your home internet access point is listed as Work rather than internet, used to have an issue with mine cause of that.
I also have this problem.
Reset did not help.
Listed as internet or work did not help in both cases.
Real weird!!
I've got the same problem, all of a sudden my hd won't connect to my router.
I can connect to open networks (wi-fi hotspots etc) so i know the wifi in the phone is working ok and my partners diamond can connect ok to my router, so the router is obviously ok.
Have reset the router as well and haven't changed any settings on the phone.
Don't understand!!!!
as other users point out within other threads, it seems that Blackstone has a problem connecting to wifi networks when WPA Authentification is enabled
try to disable it. it worked for me and soem other guys
good luck!
I could connect to my router fine using my laptop.. but I still had to reset my router to the factory settings before it worked again on my Touch HD.. then I could enable WPA and everything back again. So try that!
i thought i had a similiar problem, mine wouldnt connect to wifi, kept switching itself off. figured this is normal when its connected to usb. unplug usb and it turns back on!

Hi
I used to have problem using any secure wireless connection. Then I realized that you need a personal certificate to use secure wireless networks. It uses certificate to encrypt connection between access point. I have access to a windows certificate server so I created a personal certificate with private key and import it to my mobile. Now I can login to any secure wireless network.
A solution has been posted for data connection problems. Can be found here
This may help, may not. Let me know

That solution doesn't seem to work for this problem.
Resetting the router does seem to work.
I don't get why resetting the router works.... other devices can still connect no problems before resetting, so it only seems to be aproblem with the hd.
It also sux when you are using a public router with this problem that you can't reset.
Connecting to Belkin router
Guys, I had the same problem as well. HTC touch HD used to connect to the router fine but after installing an update/upgrade it would pick the signal from the router but would not connect. (I was using WEP authentication at this time)
SOLUTION:
Go to belkin router configuration on the web.
Under security change the Securtiy Mode to WPA/WPA2-Personal(PSK)
Change authentication to WPA-PSK
Select Encryption to TKIP and enter your password.
GO to your HTC touch HD's WiFi setting and turn Wifi ON. Select your home network SSID and edit it using the information you used on the router i.e. WPA-PSK ; TKIP, enter your key/password and click next, next and finish.
Worked for me....hope it helps.
WIFI not connecting
That truly is extremly nasty.
I have the same issue - wifi found, correct password (WEP, WPA all settings) but no successful connection.
Took an old HTC 3xxx - runs immediately.
I can not reset the router - there are too many users, they will kill me then.
So I installed an Access point (Sparklan WX 7800A) to play with.
Notebooks (HP, MSI and ASUS) have successful internet access, also the old HTC 3xxx.
But still the HTC HD does not connect.
Tried "WIFI Monster" - shows the wifi, but does not connect.
(But it deletes all wifi entries easily - so you can set them up new)
Tried with NO security/password: same issue.
WEP, WPA (all kinds): no connection
There must be something to be changed in the registry - but I have no idea what & where.
Or is the wifi that useless ?????
Maybe someone can help
Ciao
Mike
I had the same problem. But the problem stopped when i connect my htc HD to my laptop and used activesync to connect to internet. After i disconnected it, open wifi and... works ok!!

[Q] DVP not recognising home WiFi anymore.

Hi, I recently bought a 16Gb DVP on WinMo7 and for three weeks had no Wifi problems at all. It recently stopped finding my home WiFi router.It finds both neigbours routers but mine is missing from the list.
I then got an update notification for the Mango update which I competed. the router didn't return in my list of networks immediately but about two days after.
It has now dissapeared again but 'Mango' has the added 'Advanced' button to see 'known neworks'. My home router is in this lst but I cant access the settings or force any paring.
I've tried the obvious of turning it off and on. I've reset my router, reset my phone back to a clean boot of windos 7.5 (mango) and still no results for finding my router. All the other phones in the house and all laptops find it fine so I can only presume it is the DVP.
Details:
OS version - 7.10.7720.68
Firmware Version - 2250.1800.7720.219
Don't know if this helps.
Does anyone hav any idea why and what I can do to resolve it.
thanks
Jock
Try changing the SSID (name of your wireless network) to something else and see if your DVP can see it and make sure the SSID is not hidden.
Thanks, tried that last night. No luck I'm afraid.
On the router admin now and It's all as it should be fom my service provider settings.
I have a full signal of my neighbours router and just don't understand why it's chosen mine to not even find. When it appeared last time it was after turning the router off all night. I tried that again last night but it didn't appear this morning when I turned it back on.
Confused !!!
Jock
have you been able to connect to and maintain future connections to other wireless networks? if the same problems happens with other networks, I'd run a factory restore on your phone as it seems there might be a software issue. However if you can connect and then are able to re-establish a Wifi connection to other networks then I'm stumped!
I've just changed the SSID to something completely different and it's appeared and I'm now connected again.
All I can say is that it connects to the router for around a week and then the network dissapears.
Short of changing the name every 7-10 days I can't really see another resolve.
In answer to your other question, I haven't really used it on other networks.
I'll see how it goes with this new name.
Thanks for all your help and suggestions
Jock
After reading other posts, this might be an issue with the .219 firmware that you are on. Just keep checking for updates. You could try a hard reset of the phone and then a reboot of the router
Also make sure your router is set to either B or G mode. Check my post here: http://forum.xda-developers.com/showthread.php?t=1324949
Thanks, I did a hard reset when it first went off, still found nothing when it re-booted. I'll keep an eye out for the firmware update.
Thanks again.
My phone just started doing this as well. Very frustrating as I cant download large updates and I dont want to exceed my data cap. I am totally fed up with this phone!
Fixed. Called Dell. Long press network name. Press delete. Press network name when it shows again. Reenter password. Works!

Unable to connect to internet, failover set to baidu.com

Since yesterday, my Samsung galaxy tab 2 7.0 [GT-P3110] with CM 9.1.0 refused to connect to the internet over WiFi, so i thought of some issues with the tablet and installed wififixer and noticed something strange.
In the log i saw a lot of time this
Code:
>Network Check:
>I/O Exception{gateway ip address}:HTTPFail:Xms
>Network Check failed: trying again
Another strange thing was that it was trying to connect to baidu.com.
Being installed an older version i then did a factory reset and upgrade it to the latest CM11 nightly.
The update went smoothly, and now the wifi tried to connect to google.com [goodbye baidu.com] but as before, no internet connection.
Then i tough about a modem problem, and deleted the modem profile of my tablet [did the same on my tablet for the wifi profile]. still nothing, then i decided to change modem and connect the tablet to my phone via tethering, as ever nothing.
I searched a bit the net and downloaded some wifi fixer, changed the ip setting to static, changed some setting but nothing.
Sometimes the tablet seems to connect to the internet [in fact i was able to configure the google account and download a single app], but this last for a couple of second and then nothing [i don't even know what happened for making it to connect].
I hope someone have time to help me and thanks for the attention
EDIT: my fault, sometimes it continue trying to connect to baidu and not google
