[Q] Wifi problems

I'm having an issue where my wifi can't obtain an IP address from my router. I've reset both the phone and the router and it still can't connect. The password is correct. Any ideas? THanks
Edit: It goes into a loop where it tries to get an address for a while and then disconnects and then starts over

Same here. I'm rooted and get the same thing on different find including stock.

Try turning your encryption off and see if you can connect. If it connects then start working up through the encryption levels. Some devices can't handle higher level encryptions.

I'm trying to connect to open networks. So that's not the problem. hope we don't have another case of the captivate on our hands. I'm kind of in the middle right now with this phone. Possibly returning it and keeping my captivate with all its Rom flashing goodness. I know its early but this thing seems a little buggy to me and the battery isn't helping any.

I'm also having this problem. It tries to connect to the network, fails, and tries to connect again. I love this phone but I may return it and get the Attrix

Just connected, and fast!

Turning off the wifi encryption worked for me. Not ideal but ok for now.

Hate to sound noobish but......how do I turn off the encryption?

Log into your router and set wireless security to unsecured, then save changes

If get on wifi networks in different locations but have same SSID, it could cause connectivity issues (e.g., wifi SSID at my gym is "linksys", same as one of my neighbor's. My Inspire attempts to connect continuously without success to my neighbor's encrypted wifi after I've been at the gym which is an open wifi.)

Could you please fill me in on what you did to accomplish this. I am having the same exact issue it goes into a loop of trying to "obtain ip address" then disconnecting.
I have a stock inspire 4g, sig is outdated. Router was using wpa/wpa2 however i have switched through all the other available security settings (wep, no security) and the same issue persists.
Ok so now i went to the advanced settings and checked the DLNA auto-IP box, this allowed the phone to connect to the network however it still will not pull up any websites through the browser.

Been having the same problem here i can connect to my network but it times out trying to obtain an IP address disconnects and tries again. Any suggestions would be great because i can't seem to find an answer anywhere. My inspire is stock by the way never been rooted or anything

Is your router on IPv6? Needs to be on IPv4.

For those having problems with WiFi...
Change security to WEP
Put wireless router on channel 11
Try these settings first!

Still can't get it to obtain an IP address, however I got it to work by setting up a static IP address on the inspire. I would really like to get to the bottom of this problem though.

You might be having an IP conflict.. does your router allow you to assign IP per a connected device MAC address?
It basically holds a certain IP for a certain MAC address

Hmmm not sure I'll have to look into that. Havent tried to connect to any other networks yet guess that could help a bit

Have u updated the firmware on your network gear? What is your setup by the way?

Ok, tried to use a laptop today on my network and it had the same issue so I reset the whole system (i have at&t uverse) and that fixed it. Don't know why I didnt do that from that start but after I did my inspire connected first time with no problems.

I had a problem with my wireless router and my Verizon router using the same DNS gateways. I checked to see what my DLink routers DNS server/default gateway was using the commands in the run when you hit cmd+r on my PC. I then had to manually assign my phone to a static IP in wifi settings>advanced.
Example;
IP.(phone) 192.168.1.197
Gateway: 192.168.1.1
Subnet: 255.255.255.0
DNS: 192.168.1.1
For some reason my phone was automatically reading 192.168.0.1 on the DNS and gateway.

Transformer does not detect my Wifi network

Hi,
I bought my TF while I was on holliday and I was able to connect to the internet using a 3G pen connected to a router.
When I arrived home I tried to connect the TF to my home network and it does not detect it! I already restarted it several times and can't find a way of TF detecting my wifi network. All my other wifi equipments (laptop, PDA, PS3, etc) detect and connect to my network, the TF is the only one that doesn't even detects my newtork (however it detects other wifi networks form my neighbours)!
I tried to connect the TF to the router with the 3G pen and it worked only my home network is not detected!
Any explanation for this??
Without being able to connect to my broadband network the TF is useless to me...

If I was in your situation I'd either return it our root & flash a rom. When I bought my nexus s at launch i faced the same issue but fixed it by rooting & flashing

wifi setup
If it can see the networks around you then the WiFi on the tablet is working. It is either all or nothing (learned from personal experience with my transformer after a bad RMA). Since my router is set not to broadcast its SSID i had to manually setup the network info on my transformer to get it to work.

any chance you live in europe and you're router is set to channel 12-14?

THX!
any idea why that is?

You'd need to set the tablets "wifi regulatory domain" to UK or another country that allows Channels 12 & 13
Not sure if stock ROMs let you do that, KatKiss does, then you can use all 13 channels

For all who are searching for the right "wifi regulatory domain" in KatKiss - "EMEA and Rest of World" works with Channel 12 & 13.

[Q] Tab 2 7.0 WiFi Blockage?

WiFi connection reported in settings with office wifi network - says "Connected", shows 4 bars, but no data passes - no internet data, no Speedtest.net connection, Talkatone can't connect to its servers - this on same network that my Galaxy Note, and my iPad 3 connect without difficulty.
My Galaxy Tab 2 7.0 connects to my wifi home network fine, and works fine when tethered to my Galaxy Note.
I am baffled by why it says connected but no data will pass - maybe a firewall issue, but why do Note and iPad have no trouble?
I can connect to a different wifi network in our building, and data passes normally.
Any thoughts/comments/remedies?
Thanks!

This is probably not going to help much, but I had the same problem trying to tether to my phone. My solution was to install an app on the phone that configured hotspot in an infrastructure mode.
In your case, maybe your IT person can offer assistance?

Does the wireless network you're connected to have MAC filtering? I've had that happen before where the device will say it is connected and have an IP, but can't do anything because the MAC address isn't in the allowed list.

The IT assistant found that his Android phone also wouldn't pass data. I will pass along this info, maybe the chief IT guy can sort this out.
Thanks!

[Q] O3D + WiFi doesn't connect to the internet?

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.

Thanks again for all your help guys...
I ended up fixing it buy changing the IP address that the wireless router was giving it (set it to static) and also the default gateway to the same as my PC's and it worked straight away.
Still no idea why it had such a dizzy turn in the first place though!?!? :silly:

same problem please can you explain steps

Dhcp ip wont update
I have a Note 10.1 GT-N8000 running 4.0.4 but I cannot connect to our home network. We moved to PI but the note maintains the DHCP IP we used in Kuwait. I have done the following. Factory Rest, Hard Reset, statIc IP (but wont recognize), After changing the IP to static rebooted Statis IP remained. Shut down again then changed to DHCP again back to the old IP address. On the router reset, shut off,
I have another note same model no issue, an S3 No issue, A Galaxy Note1 no issue. laptop no issue. So I don't believe its the router. Any thoughts or ideas?
