Can't connect to wifi router after changing SSID - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all,
I used to connect to my Vigor 2900Gi wifi router with my S4 without any issues. Today I reset the router to factory defaults, reconfigured, used the same SSID, but different password and I wasn't able to connect to it anymore. I tried to forget the network, restart the phone, restart the router, but nothing. All other devices at home connected without any problems (win7 laptop, macbook, ipad, iphone). I decided to try with new SSID, so I reconfigured the router again. This time I was able to connect with the S4, but had a problem with the windows laptop. So, I reconfigured for 3rd time, completely new SSID. Now I'm not able to connect with the S4 again. I see the network, but it gives me "Authentication error occured". I am 100% sure the password is correct. I tried to forget the the network again and everything, but still no go.
Can anyone help, please? It's really frustrating
(And i still have the problem with the windows laptop anyway)

WiFi and GPRS frustration

I have a belkin router. It works well with several laptops.
I can connect to it with my JASJAR and get an IP address.
If I sync pop3 email it uses WIFI and works as expected.
If I sync journal bar it uses WIFI and works as expected.
However if I try to use internet explorer it alway tries to start a GPRS session and refuses to work through WIFI. :evil: Why??
Ive sent hours trying every setting I can find.
Anyone have any suggestions? :?:
Jon
At least your Wifi network doesn't crash as soon as u connect the JJ. Mine doesn't even get that far...
Anyone who can help???
Hmmm I wonder if this is something in the Telstra settings Cab.
Re those having problems all on Telstra?
Might try a hard re set and then manually build the settings.
Jon
Try de activating the phone. this allows you to use IE via your wireless router.
Tried that, thanks.
I just get the "Cannot Connect" message and if I dismiss it. Nothing!
However I can sync the weather without getting the "Cannot Connect" box. SO the WiFi is working, its just that Explorer can see it.
Im running the O2 UK firmware and it works fine (auto gives prefernce to the WiFi if I am in range, try loading on the genuine Imate firmware.

I know how you feel. I can't get wifi to work. Heck, I can't even use IE when synced to the computer via USB :evil:
Have you tried messing with the settings in start/settings/connections/connections?
I finally got it working.
You have to chose the "Telstra Internet" setting in Network Managment.
Its in Settings, Connections, Advanced, Select Networks, select "Telstra Internet".
I then did, Settings, Connections, Manage existing connections, Modem, and set it to "Auto"
It uses the WiFi first and then only uses GPRS if there is no WiFi.
Hope this helps someone else !

Can anyone help me with just getting my JJ connected to the wifi network without crashing the router?
Have you tried turning off any encryption etc and re booting the router.
Then try to connect at the most basic level?
Now I'm totally confused
I don't know what is going on!
I have finally managed to use IE via Activesync, using "Telstra Internet" as my My network connects to...
I tried again to hook up to the wifi network. The router is connected to my desktop via a physical cable, and my tablet pC is connected wirelessly (my JJ syncs with the tablet). I turned to tablet off, and then connected the JJ to the desktop wirelessly. On the desktop, I am no longer able to connect to the internet, but for some reason, the JJ is able to connect to the internet :shock:
But, even if I disconnect the JJ from the network, my desktop is unable to connect back to the internet until I reboot the router. What does this all mean????
I have the same issue with my MDA Pro! i done even have the sutp option in the modem settings. I can connect to my belkin router with encryption but no response when in IE!
Anyone else got any other suggestions?
I'm beginning to think that nobody has a solution to such connection problems. Is there any hope on the horizon? Any chance of something being sorted out by MS?
BTW, how well does BT syncing/internet connection work?
Ok frustration rising.
I can connect to my Belkin wireless router with no problems but I can only log onto the router and not browse the internet!
I have checked that the proxy is not configured.
Anyone got any ideas?
Nope

unable to connect to WLAN

Hi!
I do have problem to connect the device (o2 xda mini S) to WLAN. It recognizes the network, asks for the WPA-PSK key and then attempts to connect - but fails.
If I configure the device with a static IP this IP shows up during the
connection process after a while but the device isn't connected anyway.
If I use DHCP I get no IP ever.
I also tried a very simple 8 alphanum character key.
What may be wrong here?
I hope you get an answer soon, because I have the same problem. Enter the key, then no connect. I also tried it with security turned off on the router, no connect. This thing connected every time before 2.26 ROM update.
bump - having the same issue

Hope there's a reply; having the same issue but I think it's router specific too. I am on Dlink DI-614+ and a friend of mine who has DI-524 (i think) has no problem connecting reconnecting.
if you figure out a way to get it to work, please PM me... I have not figured out this problem yet.
I might try to disable all of my router settings (WEP).. but that would only mess my already configured other devices up.
Stupid question, but is it a B/G router or is it configured to only do one of them ?
Well, I got it to work by disabling encryption and leaving the AP all open...
So, apparently the software has some WPA-PSK-related bugs
Same thing with 2.24a Mr.Clean. Open AP works fine, and any encryption messes the whole thing up. The connection is done, it even gets the IP - and continues to blink arrows and no data comes through.
Windows Mobile only knows TKIP but as I was using AES and wanted to continue using AES on the other machines I configured the router to provide "TKIP and AES". Well, this didn't work but TKIP only actually works now.
I've been having the same problems, could connect to unsecured networks, no problems. The thing would just refuse to connect to my home WLAN (Belkin 54G set to B/G), secured with WPA-PSK and TKIP data encryption. However, just updated the router's firmware from the Belkin website, and BINGO!!!! It found the router, I entered the key and immediately connected, fast too. Just try updating the firmware of your router!
I agree on the router upgrades. And some routers are just crap, sorry to say. I've had bad luck with Belkins and Netgears. Linksys and D-Link typically give me much less problems. You also need to make sure that you installed the registry settings to enable G networks on you device (of course)
I have a Sonicwall using WPA-PSK with no problems.
I personally like molski's tweaks to make the necessary registry settings on my device ... http://forum.xda-developers.com/viewtopic.php?t=58438
Hope I was of some help.

connecting my XDA to a different router

Hello,
I have got two wireless routers at home and my XDA Exec is connected to wireless router A.
i am trying to change the settings on my xda so that it connects to wireless router B, but i cant find the place where i can change the settings,
can you guys help me.
hi
i have managed to find out how to delete items from the list, by pushing hard on the stylus, i get the option of removing from the list.
I can't connect to the network which i want to connect to, originally i had it connect to my network "BTHome-hub" with no problem, and i wanted it to connect to my netgear router which is an unencrypted network, not connected to the internet.
to force it to reject the BTHome_hub, i changed the WEP key(yes, i am a noobie), so that i could get the next network, and then i started getting this problem of the xda showing all the devices in the neigbourhood as available (and some old devices which is shows as unavailable), and it runs through each of those available devices, trying to connect to each of them, and it fails to do that.
i have gone through a number of the posts on the forums. and have tried the following.
1. change Power Mode to Best Performance !! in my Wifi Settings.
2. i had no mac filtering on any of my routers, and have turned on mac router on one of the routers and added the mac address of my xda
3. i tried the following start-settings-connections-network cards-my network card connects work and rest to internet, this time around i was prompted for a password, whereas neither does my router have a password and the authentications i open and data encryption is disabled
(does connects to (in configure wireless network) the internet/work make any difference?
if one of the routers has a strongers signal than the other, would the xda wireless get confused and try to connect to the router with the stronger signal?
i was thinking that channel 11(on which i am) is quite busy and hence i changed the channel to channel 1, do i need to make the channel modiiications on the xda as well
what does the soft reset rest?
a) soft reset is like turning your desktop/laptop computer off and then on again. hard reset is like reinstalling the operating system on your pc.
b) if one router has such a bad signal that the universal loses the connection, the uni will look for another router. it will ask you which new one to connect to unless it already has settings for a new one.
c) if you're getting interference problems, set the router to channel 13. it's europe-legal only so american routers don't usually use it. your clients (pc's and your universal) will scan for the right channel.
d) at the pc shop where i work, we get LOTS of problems with BT Home Hubs' wifi - so don't think it's your fault, it probably isn't.

VERY strange WIFI problem on Wing

Guys,
I have had my wing for almost a year. The WiFi has always worked. Something strange is happening to my wing now that I can't quite explain. Now when I try to connect via wifi, it connects to my router, but no IP adress. What's worse, when it does connect to my network, my laptop's connection gets screwed up. The laptop no longer can connect to the wifi network.
I changed the IP address on the laptop so that it isn't in the DHCP range thinking that the router is just giving the same IP adress twice. No dice. It's just weird since I had this exact same setup working a week or two ago. Obviously, I've soft reset the device. I would like not to have to hard reset the phone. It's almost as if the Wing is messing up the rest of the network.
Any ideas?

Failed to obtain IP (HELP)

It might be a problem with the router itself, or the passphrase you're entering could be incorrect? Please try connecting the phone to another WiFi hotspot when available and see this works.
the problem might be with the router because i was able to connect to the router where my dad works, but my home one it won't.
I use belkin router and not sure how to fix it anymore though
Some basic troubleshooting questions:
1. Can your phone connect to other routers? If so, are they secured or open?
2. Can other devices connect to your router reliably?
3. Is the error actually that it fails to obtain an IP or that it fails to connect or authenticate? IP address assignment happens after successfully authenticating with wireless security, so if the actual error is that it can't obtain an IP, that implies that something is wrong with your DHCP configuration, likely on the router.
