[Q] Hero won't connect to WiFi

So, I've searched for a bit, on here and Google, but not having much luck. My phone has always been good at connecting to WiFi hotspots. However, I am currently visiting a house that has a Wireless N router and using WPA2 security, and it won't connect.
Is it true that these phones have issues connecting to that or is there a fix?

Well the hero only has b/g wireless capabilities, change the wireles router to also brodcast in g mode, since n will not work.

Here is the odd thing. I mentioned about it to the person who setup the wireless network, and he said that the router is broadcasting in B, G, and N. My phone detects it, but when it attemps to connect to it, it says "Disconnected". Am I doing something wrong or is there something missing in my phone?

My phone connects just fine to my N router. There might be setting restrictions that need to be changed on the router via the administrative computer

WIFI router not working on Tilt 2 with Energy rom

I have been using the WIFI router on my tilt 2 ever since I got it, I even bought the WM WIFI Router program in the Windows Market, and that doesn't work either. Iam using the energy 27.dec.2010 and I even tried using another energy rom also, no luck. Everything goes with the startup, the device connects and I see I have a good connection, but when I try to use browser/data its saying its not connected to the online signal. Its seems to pair fine and connect but I can't use any features with data even though I have full WIFI bars and all the icons are correct. I even tried it with another sim, nothing. Anyone else having this problem?

Have you tried any other roms here on the forum to see if any of them have same issue?

fwiw the WiFi Router included in every Energy version I've flashed works fine, latest is about mid Feb I think.
Are you sure the device you're trying to connect to the phone fully supports adhoc connections? I had a Linux distro do that to me not too many years ago... everything appeared fine but wouldn't communicate through a legit version of router software that worked fine with a Windows laptop (same one actually). When I emailed tech support they apologized and told me that "feature" was still in development.

Yes they do support adhoc connections. They will both connect fine but its like its somehow not getting a signal. I can use usb to teather to media net and.connect. but still can't get the wifi router working. And also after I connect with wifi router but before I connect a.device the wifi icon that's is supposed to be blue is blinking blue before I connect a device I don't remember this happening before?

Droid can't see wifi router

I have an unrooted OG Droid running on stock Froyo (2.2.3). It's off-contract, but I have been using it by connecting to my wifi router (Netgear WNDR3700). Everything has been working fine until Friday when it stopped connecting to my wifi router. I tried reconnecting, but it cannot seem to find the router at all, even if I'm standing right next to it. My router does not appear on the list of available wi-fi networks when I look at Settings -> Wireless & networks -> Wi-fi settings. The strange thing is that it seems to pick up all of the other wi-fi networks from my neighbors without any problems; it just can't seem to find my wifi router.
All of my other Android devices (Nexus S, Evo 3D, Galaxy Tab, Logitech Revue) can find and connect to my router without any problems. It's just as though the router doesn't even exist from the perspective of the OG Droid. I haven't made any recent configuration changes on any of my devices or router. My other wi-fi devices (laptops, printer) don't have any issues finding and connecting to my router either.
I've tried rebooting, pulling the battery, etc. without any luck. Any ideas?

By chance did you unplug the router, my og DROID loses wifi sometimes and even though phone sees it won't connect but usually resetting router gets it to reconnect.

I haven't done that yet, because as far as I can tell, the router is working fine. The issue that I'm seeing differs from yours as the phone doesn't even see the router right now.

It's a bug in Android. Delete all the remembered wifi accounts on the phone and then you should be able to scan again. Once you scan, it should pick up the router again. Had this happen on a couple different android devices.

I gave this a try, but it didn't work. I can still see all of the other available wi-fi networks near me, but not my own router. Any other thoughts?

I've had this with my router whenever i reset it.
its because there are too many routers in your area on the same wifi channels . change the channel your router is on until its one with less or no routers on it and it will appear eventaullly.

I have same problem with you.
My LWW cannot find/detect the home wifi, but another device (laptop and samsung galaxy mini) can work well with the wifi network.
but my LWW can find another wifi network except my home network. but sometimes when I don't use the LWW for long time, and when I started to turn the wifi on, it can work well. but after I stopped the connection and start to use the wifi again, it cannot find the network again

I just had the same problem and fixed it.
Sometimes routers are configured to select and use the less crowded wireless channel. That can cause your wifi to eventually use channel 12 or 14. Like sleepyguy007 said, it is more likely to happen if there are too many wifis in the area and all channels are crowded.
As far as I know, Android devices are by default configured to scan only up to channel 11. So if the wifi is in 12 or 14, it will not be recognized.
Go to the wifi config screen, where all the networks are listed. There, with the menu button, go to "Advanced"->"Regulator domain" and set Android to scan all 14 channels, that should do the trick.
I hope that is the cause of the problem and you can fix it... Otherwise it could be a bug, and the solution may be harder

I'm so happy & surprised!!!
I had same problem and with your helps(phobophille & sleepyguy007) my problem solved:laugh: :fingers-crossed: :good:

Had a look round seems to be a problem on the Galaxy SII also. Just for info I have not added any new apps for days.. must be the phone buy why?
Any ideas?
Thanks

Lets try this:
Check whether your laptop can get an IP from your wifi.
I. YES
- Turn on wifi on your note.
- Go to Applications -> Settings -> Wifi settings.
- Look down at Wifi network.
- Touch into the name of your wifi then choose "Forget network".
- Turn off wifi on your note.
- Turn it on again.
- Enter the key and see what's happen.
II. NO
- Check your router configuration.

If you hav have enabled mac protection on router, reset it.

Hi,
Laptops x3 and other peoples phones can get onto WiFi ok, both at work and at home, my Note Will connect ok to the BTFON / BTOpenzone (off of the same routers) with no problems again both at work and at home. We have changed nothing with the routers (BTHome hub 2 and BTBusiness hub at work).
Can you advise what to check with the router as all seems to be in order for all other WiFi devices, it's just my Note that is having a fit and wont connect?
Many Thanks

Hi, Re mac protection, the routers auto set up and I am unaware how to check re mac protection. I cant understand why has my Note decided to stop connecting out of the blue?

I have similar issues.
I have setup a WIFI hotspot and all my non-Android devices can login without any issues (Notebooks x2, iphone3, iphone4, ipad), however my Note and my Blade (all running 2.3.6) and an Acer A500 Tablet (running Android 3.1) cannot connect.
The android devices see the hotspot and will attempt to get an IP, but most of the time will not succeed.
Any suggestions?

I'm having the same problem with the "stuck at obtaning IP address" problem.
Just got my Note 2 weeks ago and am still not able to connect to the internet using wifi.
I can't connect to my home wifi nor starbucks nor any other public wifi. When i use static address, i was able to connect to my home wifi BUT could not use the internet. I really do not know what to do...PLEASE HELP!!!

I too have experienced this. Running stock 2.3.6 + root. happened with lots of different routers. Usually solved with power cycling router & note wifi. Very annoying.

I think (personally), it has nothing to do with the Note at all, BUT on most samsung smartphones...
I read somewhere that Sammy's phones have a weak side in detecting and connecting to any wifi device...
I personally tested this also with my Note, side by side with my friend's Nokia, a Blackberry and a Galaxy Nexus as well.. both Samsung phones stucked at "Obtaining IP address..." for some time, while the two phones (Nokia and the blackberry) connected thru wifi with ease... no problems at all..

I have same problem periodically at my sister's house, especially when a lot of other mobile devices using the router. If you google the issue there are many with same problem.
Simplest way to solve it for me has been to unplug & then plug the router back in. Rather annoying.

I had same prob with my galaxy tab... Forgetting a network won't help..
Nor there is fault of router...
Google this problem you will find results with solutions for xda only... (did the same but don't remember the link)
Al t bst!!

HELP: No WiFi Error: DNS_PROBE_POSSIBLE

Hi,
I'm at a conference and I've lost wifi access from my XPZ (C6603). I'm on stock 4.2.2 build 10.3.1.A.2.67
The phone connects to the main network, but then there's no internet access. My colleague has a XPS and connects without a problem and mine was working yesterday. I have access when connecting through LTE but I'm paying roaming
Google chrome tells me error: DNS_PROBE_POSSIBLE. I have tried many things already google search for the problem, restart phone several times, forget network, changes in DNS from DHC to static, ...
Any solution before trying to re-install the phone firmware?
Thanks a lot!:crying:

In the meantime, the problem solved by itself. When I returned to the hotel I had no problem in connecting to the hotel's wifi and then the next day I could connect at the conference site.
So it seems that some how the problem is in between the phone and the router that gets stuck to an IP address and the solution passes trough either connecting to a different hotspot or reseting the routers.

As it turns out for my situation is that the hospital has been having Internet issues. Perhaps all they need to do is reset the router. Considering I'm hooked up to several machines, I'll continue to use my mobile data.
