Hi,
I have a problem with the wifi on my Samsung Galaxy S2 after I changed some settings on my home router. The wifi works anywhere else, just not at home.
What I changed was the router ip and wireless channel. Since then I have cleared all the wireless and browser settings in the phone and reverted back to the old settings on the router. Still doesn't work.
I've also tried having static IP. It doesn't work as well. It's only the internet. It connects to the router fine and I haven't had any problems with other gadgets and computers connecting.
Your tried turning on airplane mode for a few then reboot?
Your router doesn't have a sync button does it?

One thing you can do is delete the connection to your router on your phone, and connect again with new password from router. Do you have any other device beside your phone connecting to this router? If no, you need to test it. If yes and not connecting check the connection security, like wpa or wpa2. If all fail, reset router. This mean you will need to reconfigure your router. Check manual for more on your router.

Yes. View available wireless connections. Click your router. Then click "forget".
Then view again, click your router, and type the passphrase.

Just tried this and it didn't work.
My router is a cheap basic router that came from my internet provider. No such thing on it.

I've already reset anything wifi related on my phone. It hasn't worked.
Do you have something else that you can connect to wifi to see if the problem is your router?

Not in my home no. But like I said in the OP, the wifi on my phone works fine in other houses and hotspots. It's most definitely some kind of communication problem between my router and phone only but I'm not familiar enough with routers to know the problem and I haven't stumbled on anyone else on google having the same problem.
Two laptops, one Win7 and one OsX, are connected. Unfortunately I'm new in the area I live in and my girlfriend doesn't have a smartphone so I haven't been able to test if it's just my phone or just android or iPhones in general.
I can't think of a logical reason why it's like this
Maybe router is configured with wifi 802.11n and the galaxy only runs on b/g ?
If you're using WPA/WPA2 security, check that the
router is set to use AES encryption.
If you think you did your best. Its better to buy a new router then. )
maybe you could try unplugging your router?

I didn't change any of that. It's got a WEP encryption only as well.

I'm having a technical problem with my home Wi-Fi router, and my Fuze. I just recently set up a wireless network at home, and have my PC connected to the router through Wi-Fi. Whenever I attempt to connect my Fuze to the router, the Fuze hijacks the connection, and disconnects my PC from the network. I have tried to contact the tech support for the router, but nothing they suggest seems to work. Has anyone else experienced this? Is there something I am missing in the router configuration? Any help would be greatly appreciated.

i've used my fuze on multiple routers and it doesnt do this. Get a new router
If you give static ip on both pc and ppc check if you gave the same ip. If not, check the dhcp range on your router.

First thing I would try is updating the firmware, and doing a factory restore.
If that doesn't work, try changing the router to force 54g connections only. It's possible, but unlikely, that the Draft-N spec used by the router doesn't play nicely with the WLAN chipset in the Touch Pro.

agreed, i would try this first. makes sense that if they both have the same ip that that is the cause of your problem. if you're set to assign dynamic ip's on connecting to the router, then i'd try upgrading the firmware. good thing to check first
Still having problems with this issue. Tried everything suggested so far.
Make sure the IP's are not conflicting and the dhcp range is at least 10 addresses.
It could also be a neighbor screwing around, make sure you encrypt your wifi with wpa or wpa2 or anyone in range can use your wifi.
When I first read your problem I thought it was an IP conflict with both devices like some others have said....but if you've checked everything and tried all possible solutions posted in this thread I think it might be pretty safe to assume that you need a new router. If its new, just bring it back and exchange it for a different one.
I'm using a D-Link DIR-655P and have connection types (B, G, N) on auto, dynamic IP address assignment set, and I have the latest firmware installed and I have no issues whatsoever...I have a quick lock and fast speeds.
I've got a few questions, because to me this sounds like a possible issue with your network adapter on your PC, rather than a DHCP "hijack" issue.
What is the ip on your PC after it gets "hijacked"?
Do you use sleep/hibernate modes on your PC?
Have you turned off Windows Firewall or any other security/virus/malware software on the PC?
This router is new, did this setup work with a previous router?
What security protocol are you using for wireless connections, WEP, WPA, WPA2, or none?
-----------------
Hope you can figure it out, that's gotta be a real PITA.
Got it fixed. Did some more research, and found that the firmware updates do not work with Firefox, so I used IE to do the update, and it works fine. For anyone else that uses or is planning to use this router, check the firmware. The firmware version that mine came with (1.0.4 build 10) does not work with multiple versions of Windows (ie: cannot have a computer with Win XP and another with Win Vista connected at the same time). Thanks for the help.
Ahhh...well there you go. Glad its fixed.
I had issues today connecting the Inspire to my home Wi-fi.
Initially I had my Wi-fi setup to not broadcast the SID. When I add the network to the phone it is listed as "Not in Range".
As soon as I change the router to broadcast the SID, the phone connects as expected.
Anyone have any insights? Anyone able to confirm?
--wookiefoot
I also hide my SID on my router and my Inspire connects just fine.
Try rebooting your router? I had an issue the other week where my Captivate wouldn't get an IP address from my router, but I just rebooted the router and it worked fine after that. I figured it was just a glitch.
i just cant connect. says obtaining ip address

Make sure the IP its trying to connect to isn't in use by another device.

Connected to the 802.11n router fine.

I'll give the router reboot a try. Seems odd that I can toggle SID visibility on/off and watch the phone disconnect and connect based on that.
My temp fix was to leave SID visible then lock down MAC filtering. Not very convenient when new devices need to connect though.
Will update with results in a bit.
Sounds more like a DHCP issue rather than a SID issue. Check your DHCP settings. That is where it gets the IP address from. You could also give it a static IP or create a reservation for it so it forces the IP. Good luck.

Setup DHCP Reservation for the phone. Still no luck. As soon as I switch the visibility of the SID, the phone disconnects and lists the network as "Not in Range".
Not doing anything special with security:
Mode: WPA-Personal
WPA Mode: Auto (WPA or WPA2)
Cipher Type: TKIP and AES
FYI - router reboot didn't resolve the issue either. (Model: D-link 655)
Any other thoughts?
First of all may I say I have searched for this problem on google, as well as xda forum. I did find several threads about this problem, but none of the solutions presented appear to be my case.
So, basically the problem is: I cannot connect to my home router, a Linksys WRT300N N-router. I could not connect with a N1, HTC Desire, nor with my actual NS. My previous Galaxy S was connecting fine though. I'm talking here about stock ROM, no rooting, no custom kernel etc. Also, using static IP address works like a charm, but then WiFi cannot be used on other outside routers, since Static Ip setting is not setup PER router, but rather per WiFi connection, meaning the phone will try to use the static IP defined for any WiFi I run into.
From My experience, it seems it could be related to wireless N router as opposed to b/g. This happened since I replaced my router with the actual one. Ever since this happened, my phone would not connect to my router. Also, this problem seems to be presentfor any N-router, since I cannot connect to WiFi in other locations as well (which might have N-routers as well).
Assuming that it is a problem with N-routers, I don't understand why the Galaxy S would connect, but NS not, since they are almost the same hw.
Does anyone have a clue on this? But please skip solutions like reset router, reset phone, reset modem, use different ROM etc. I am talking stock ROM for all the examples above.
Thanks.
I use my NS with three 802.11N routers without issue (D-Link, Belkin and Netgear).
Have you checked if MAC filtering on the router is active? What security mode are you using? Who makes yr router and does it have latest fw?

Just seen you use Linksys, I have a wag160n and I find it unsusable on terms of wifi, dreadful hardware, despite the parent company being Cisco
Check Linksys forums for problems.
Try another router for whether it's that or phone at fault.

MAC filtering is disabled, I've checked it. Security is, on the router, PSK-Personal with TKIP encryption. Key renewal: 7200 sec. Not sure if this can influence anything.
I've checked on linksys page for fw upgrade, they only have pdf manuals.

Have you checked that you set up the router with b/g/n protocols? not only N..
Try to change the password encrypting method, to WPA or WPA2 or WEP, try also to change the default password.
Have you tried to disable the firewall (DMZ)?
I have exactly the same issue on my stock Desire.....
I have recently upgraded my router from a Belkin G+ to a Belkin N+ and using the b/g/n setting the desire WILL see the connection but will NOT connect to it, NO MATTER WHAT settings you try. Changing it to b/g and it will connect without any issues.
It is my understanding that the Desire/Nexus et al doesnt have the access to the N ability enabled (it has the correct chipset but for some reason it is not active).
Maybe when broadcasting the tri-band the chipset only sees the stronger N connection, therefore tries to connect but gets conflicted (due to lack of N firmware) and instead of switching to b/g it just loops to the stronger signal. IF that makes any sense

Well, the funny part is that I don't even know how to disable the N range to my Linksys 300N.
Anyway, it is weird that the Samsung Galaxy S had no issues with this, while Nexus S (still Samsung made, brother-in-law to SGS) has this issue. For HTC, all have had this problem, including Desire, Desire HD, Wildfire.
Still no explanation or resolution to this matter.
I may have fixed this issue (well I have for me anyway, so yay).
After posting this I decided to apply some weird logic to it. So I reset the router back to b/g, to do this you need to log into the router IP settings, for Belkin it is 192.168.2.1. On linksys routers I think it is 192.168.1.1 but check to be sure.
Once you are logged in there you can change the broadcast settings from N, b/g/n or b/g etc.
Okay, so here is what I did. I reset the router to broadcast b/g only, my Desire would connect. So I decided to try resetting the router to broadcast b/g/n (because I use N on other devices) and then switched the wifi on the desire off and back on again. Low and behold it connects.......Tried it loads of times now and connects everytime!
Might be worth a try?
You guys should just check the logs on the router and see what they say. Should give you a much better idea of what the issue is. You can then Google the error line.
Mine is fixed now, been connecting to various N routers with NO probs since I did the workaround.
My guess would be a protocol conflict (wireless handshake if you prefer) when N routers are broadcasting (based on the fact that the Desire/Nexus etc dont have N protocol enabled in the chipset firmware).
To get around the conflict connect to an N router using the b/g only setting in the routers IP settings and then check you can connect okay and switch the b/g/n back on in the router. I've done this twice today (different N routers, a Linksys and a D-Link) and it works on both where it wouldnt before, so it wasnt just my router.
hum... i am having the exact same problem as described only my router is already using
802.11g&802.11b
i have no idea why it keeps trying to obtain ip address
then it scans agains because it can't connect and tries to obtain the ip again
after trying for a minute or 2, the home ssid becomes:
"disabled, secured with..."
(device = motorola atrix)
I have tried everything and still not working... do routers block Mac addresses if it doesn't connect right away?

Make sure your router has the latest firmware available, then power cycle it and try connecting with the TP again.
Might need to change it to WPA for it to work.
Coincidentally, mine wont connect to my netgear router for wireless N - sees it, but won't connect to it regardless of settings, connects instantly using G.....

I will try this also, thanks for the advice
This is a strange one, because it used to do it and nothing has changed.
The WiFi can obtain an IP from the router, it can connect to my PC via the router.... but it just cant connect to the internet via the router?
If I disconnect the WiFi and just use data, everything that has been waiting comes flying through!
Any ideas what is going wrong, the phone says it's connected, but I could swear my WiFi symbol used to go green, but it is just staying white.
Running 21E OS.
TIA.
Couldn't really understand (no offence) but if this happens to me I usually just restart my router and it would work again.

Do perhaps have a Netgear router ?
If yes reboot the router
Change wifi Channel from Auto to 6 or 7
if not try the above also try setting up a static ip
Do you have Droidwall installed?

Yeah I do have a Netgear wireless, I left everything off all night but no joy... I will try your channel change thing and see if that works. It's strange because it used to work and i haven't changed anything that I am aware of and the PC has no problem. But obviously nothing is being sent to the Cisco CM. Hmmm....
Thanks for the input guys. :good:
Sorry OptimusTM, it probably was a bit garbled in my original post.... basically the PC gets to the internet (probably like most folks here) by contacting the wireless, then the wireless contacts the cable modem then it goes to the internet.
However my O3D can contact the wireless, but the wireless doesn't seem to contact the cable modem for some reason, however it will contact the PC.
The phone says it's connected to the wireless. It has been given it's IP address.
Check your DNS server address.
Put manually 8.8.8.8 and tell us if it works.
