Problem connecting 2 tablets to the internet at the same time - Eee Pad Transformer General

Hi All:
I recently bought a Nexus 7 in addition to my year old TF101. I am having problems accessing the internet (via wifi) on both devices at the same time. For example, if I were using the TF101 while turning on the Nexus, the Nexus would not be able to access the internet (all connections would time out). The LAN works on both devices at the same time so it is not a problem with the router. Internet access would start working on the Nexus a few minutes after I turn off the TF101. I am using the same Google account on both devices. Could that be causing the problem? Any suggestions to resolve the issue would be much appreciated.
Thanks. .. KS

Its a not the Google account. I am currently in logged in on 3 devices. Chances are your router is set to only allow you one wifi device at a time, Some are like a that. Try Google your router's, make to find instructions how to change it.

Thanks. It was indeed related to the router... somehow the 2 tablets were using the same static IP but they were shown to have been assigned different IPs when I checked inside the router. Now resolved and working well.

Galaxy Note disrupts connection with Wireless router and Desktop computer

Hello
This just started today after 1 day after I bought my Galaxy Note. Sometimes I'm on Wi-Fi on the Note and I'm on my desktop computer, my computer connection to the internet gets disconnected. The WiFi on the phone still works, but I can't visit any websites anymore.
I just received a call and talked for a minute, then my computer connection didn't work for a minute as I tried to load up different websites. Now it's back on. I find this strange. I tried two different routers as well (Cisco and Linksys). Both of them experienced this issue. I tried different ethernet cables as well.
Has anyone else experienced this? Is there a setting I need to change on the Galaxy Note? I'm new to Android.
I guess the problem is on your router / modem. I haven't heard of a similar problem before.

I have a similar problem on the phone sometimes. WiFi signal will be activated on the phone with full bars, but the phone is still unable to connect to network or visit any websites. Sometimes I get the message 'could not connect to network'. This problem is intermittent but annoying.

Probably best to set a fixed IP address for each device. I find that solves a lot of problems. Sometimes as devices join and leave (like if WiFi goes off) they take each-others IP addresses, and when re-joining the hookup fails.
Sometime I am facing this issue also. Then only I have to reboot ADSL router. Mine is Netgear.

I remember one crazy incident in the past. I had one pre-sample Acer Android phone and randomly some colleague in the same room wouldn't be able to browse in their laptop. After lots of fiddling around, realized that phone was running DHCP service on its own and it was leasing out different IPs to laptops connected to parent wifi router. (So there were two DHCP servers, one in wifi router, another in android phone and laptops connecting to the wifi router were sometimes getting IP issued by the phone).
News to me and i have a lot of devices connected to my router

[Q] Problems connecting to wifi network: looping "obtaining IP address"

There appears to be a problem with new versions of Android and old routers. Many people have reported the "obtaining IP address" loop problem.
Let me explain. I use the leisure facilities in a local hotel. It has a public (open) wifi network. I believe it uses an old router. My Galaxy S2 (Gingerbread) and AsusTransformer (ICS) both connected to this network without problems. I recently replaced the S2 with an S3 (ICS) and my Transformer with a Nexus 7 (Jellybean). Neither of my new devices connect to this network. I have had the same problem in a local cafe.
I have researched this problem. It is not uncommon. It appears to be caused by an odd mix of hardware (router and wifi chipset) and software (later versions of Android). If you are unlucky (like me and some others) you will be unable to connect to some networks.
The solution is to use static IP addressing (since your device is unable to obtain a dynamic IP address). This will allow your device to connect to the network -- but you need to know the correct settings (for static IP addressing) before you can actually use the network.
This problem has been reported by many people. Does anyone know if there is a fix or a workaround?
The only one I can think of it to get hold of a device that does connect to this network and copy the (static IP) settings. But this would only solve it for one location meaning that I will run into it again the next time I try to connect to a network with old hardware.
Sometimes when I get that problem it's due to IP address conflicts on the Windows 7 computers.
I go to the computer and:
http://helpdeskgeek.com/networking/release-and-renew-an-ip-address/
Otherwise I just pull the router out and refresh it, should work for another few weeks or so.

I don't have access to the PC. It is owned by the hotel. I need a solution that I can apply client (Nexus) side.
Solution
I found a solution. I asked the guy to reset the router and both my Nexus and S3 immediately connected. Someone advised me to do this. I have no idea why it worked. Not really a solution since i cant go round cafes asking people to reset their routers for me.
Is there a way to find out IP, DNS, gateway etc values on Nexus when they are dynamically assigned?
I sometimes have this Problem when starting my accesspoint after enabeling wifi on my N7.
I have to reboot my N7 in that case to get an IP.
Happened to me quite a few times when I went out with it to a restaurant or something. It just loops and loops.
My Nexus (and S3) now connect to the hotel network every time now. So it looks like you only need to ask the owned to reset his router once.

Resetting the modem solves the problem if you don't make any change to the router settings. I don't understand why the hell google is not solving the problem yet...
many users are found to face the same problem..
eve I can connect with my Nokia E72 but not with my N7...
I can get the IP from my cell phone. But come on, what's the point of doing so?? Are you gonna assign the IP for each and every WiFi you connect?? Or if the IP changes everyday??
Static ip won't help, yes you can connect to wifi, but cannot get connection to internet. This is a bug of android, and ITs in Princeton univ. had some investigation. 412 should have fixed it

I just started having a similar problem. I have a samsung galaxy tab with Sprint. I've had it for a year and this is the first time I've had this trouble.
The only difference is, I cannot connect to any wifi network at all. It keeps hanging on "obtaining IP address" and then disconnects. It doesn't matter if it's my home wifi or school or free wifi in a restaurant.
The only possible connection I can make is that I downloaded Lookout to check it out as a possible security app, I have since uninstalled it but that did not fix my problem.
Continuing to research this but any ideas on how to fix this would be fantastic.
I'm having this problem on my HTC One S. It happened yesterday without warning and it's really annoying. I went to a nearby cafe and the wifi worked perfectly, so it's something wrong here.
Static IP solution connects to me to the network but I can't actually use the internet, so I'm stumped.
i'm getting the same error with AOKP 4.2.2, and also know people with stock 4.2.2 with it.
the only way i found to fix it is to reboot the phone..... and wait for it to happen again and reboot it again
i cannot use static IP since in my university (and some other public places) it is not possible to connect it like that :S

[Q] HELP!!! N7 3G wifi tether IP address conflict HELP!!!

So, I'm deployed right now and I got the N7 3G specifically so I could tether to my computer and phone. After getting the device and realizing that it did not have native tether I rooted it and flashed it with the image(?) I found here.
http://forum.xda-developers.com/showthread.php?t=1995737
Everything went smoothly and I thought I was good 2 go. When I attempt to log on with my devices I get a IP address conflict. My computer (WIN7) is smart enough to manually assign itself an IP and connect to the internet but nothing else will. It's driving me nuts. Obviously, I can only imagine that it is something to do with the DHCP. I would have posed this question on that thread but based on not having posted before I did not have the permissions. Thank anyone ahead of time for any help.
Still no luck. I've reapplied everything multiple times and nothing. I've also flashed the monoco(?) rom hoping that their tether would work but nothing. Only thing I haven't done is factory restore and start from scratch. This is really sucking. I'm looking for any suggestions. I'm sure 90% are more experienced then I am with this. I have absolutely no programing knowledge.

Hmmm. Yea its DHCP from your Nexus handing out IPs. I'm not sure what your DHCP RANGE is but it should be a pool of about 10 IPs. If your Range is only set to 1, then it will only hand out one.
Oddly there aren't any options on my Galaxy Nexus (I don't have a 3G N7).
What I would do is take your other devices and tap and hold on your tethered WiFi network and select forget. Disconnect everything completely and forget all settings. Change your WiFi Tethered name.
Try to connect one at a time before moving to the next. The devices keep the connection settings in memory and will try to use the old IP address they used before.
This could also be a bug with the tether section also. Most roms share the same development features.

but when i went to next i logged into my gmail account and i get this
"Couldn't sign in

Expected it is not any Hardware issue, it seems your pb is related to your PW. try desabling it from your router (just a short time for test) or go to a free wifi place to check.
Also keyboard issue, do you use the standard one?
good luck

The obvious thing in your router configuration is that connections are being restricted to a list of hardware mac addresses.

Nexus 4 Wifi Issues - connects to router but no internet

Just want to know who else on XDA has a similar problem to me on the Nexus 4.
Recently moved country and took my Nexus 4 with me, got a data plan, no problems there. I was also was given the stock router for my ISP (Movistar) when taking out my broadband contract and my Nexus 4 is the only device that won't connect to wifi.
So here's what happens:
1) Network can be seen on the Android 4.2.2 Wifi Settings
2) I can connect, either by WPS or by entering the password, and Nexus 4 shows connected with indicator
3) Indicator instead of being the standard blue is grey, which seems to be no internet connection. I can get some access but at very, very slow speeds (about 9kbps)
The Nexus 4 is the only device in my house with the issue, no problems on PCs, iPads, etc.
Google have acknowledged this is a bug and there is a fix which involves root, but I don't want to root at the moment. Google also say it'll be fixed in the next update, but they've said that and we've seen 4.2.1 and 4.2.2 come out in the meantime.
Google Support also sent me a rubbish response to my questions about when it'll be fixed, telling me what Wifi is and how to turn it on and off..
So just want to know, are you having the similar issues with certain routers on 4.2.2 (stock)? I know I'm not the only one but I couldn't find any other threads.
Thanks!
I started having this same issue man! care to show me whats the root needing fix?

There are a lot of fixes in the Android Development Section.
Typically this can be a DNS problem if your router is not correctly set up to relay DNS requests (windows/OSX tends to be a lil smarter about it if it can't get the appropriate response from the router).
You could try to set a DNS yourself such as google's public ( 8.8.4.4 and 8.8.8.8 ) in the advanced properties when you long press the SSID you're connected to and see if that allows for internet access. If it does, then maybe you just need to log into your router and correct the DNS info.
Thanks for the responses guys

Tried that I'm afraid :/ No luck. According to Google it is the fact "they have no drivers for that router" considering they will probably have a generic driver for the average user to connect whatever the router.
Sadly I've had to practically try everything to get it to work. Thanks so much for your response though!

Hi! It's an annoying issue, I'm currently tethering through Mac to get it to work. The root fix does work but drains battery life a lot more (instead of 0.5% per hour drain it's 5%). If you want to look I'll pass the link, but wouldn't recommend it.

See if you're able to do a traceroute from within android when connect to the router to see where it's failing.

And about changing routers, not possible at the moment. I've just moved abroad and have my old router somewhere too hard to find. Google are no help with this which is the problem, but if it persists in the next update I'll get a new router whatever the case.
It's strange since my iPad and all my other devices work with no problems!

The Nexus is a great phone, just a few odd issues which hopefully will be fixed.
This issue is persistent but dependant on the router. For example, my extender works perfectly whilst the main router doesn't - let me know what your router model is and I'll check to see if this will be common for your router

Hi!
Taken a quick look and doesn't seem to be any problems with your router. What you can do is to purchase the device and test to see it works on WiFi.
If it works, you're good to go!
If not, try some troubleshooting, so change channels, IP address, or even just a reset of the router could work.
Still not working? You can try what I did and buy an extender, but that'll set you back a bit of money.
You could wait until this is fixed, which we don't know when yet, or if you can't fix it you have a return period on which you should get a refund from Google.
Let me know what you decide to do, personally I'd try it out since it's likely to work, but I would return if not. But the Nexus 4 is a great overall device for the price.
Hope this helps!

OP, have you checked to see if this is an issue with the wifi access point of your router, or actually a routing issue?
To do this, set up ftp services on your computer or phone and login from the other device and copy a file from one to the other. If the bandwidth is good, your problem isn't with wifi but rather a routing issue that can likely be addressed in its settings.

I'm about certain this is to do with the router itself and not a routing issue, this is a common nexus4-my router problem and various other models.
I've adjusted every setting possible in the router settings to no avail, and all of my other devices which include other android devices work perfectly.
Sadly it seems to lie with a Qualcomm driver from what I've seen, and hopefully Google can fix in the next update

If you don't bother to check if you have good throughput over your LAN, you'll never know whether this is a wifi issue or a routing issue.
Drivers talk to hardware, i.e. Your wifi chip. That is all local, and has nothing to do with the routing (Internet) part of your router. Without knowing where the actual issue lies, you're just guessing if a new wifi driver will help.

Sorry, you seem to have misunderstood me and you're obviously making the assumption that I haven't already checked for routing issues.
As I said, my Nexus 4 is the only device in my house with this problem, all others work perfectly. From what I've gathered from these issues, it lies within the drivers of the phone.
WiFi works perfectly on every other router I've used with my N4, it's only my home router with the problem. It's a Movistar default router and other users have the same problems with this router (the brand is fairly unknown).
And I'm definitely not guessing that it's a driver issue - I've had this problem for over a month, I've tried everything I can: changing router settings, resetting, etc. So I doubt this is a routing issue but more an issue with the device, and from what I've read on other forums, this could be down to a Qualcomm driver issue.
Thanks for your help anyway!

I am not assuming anything. Simple troubleshooting 101. You're not getting a decent Internet connection. Could be wifi or router. I merely offered a simple method for determining which one.
Don't know who you spoke with at Google, but first couple of support levels don't have the stones to try and solve these things. And while I have no doubt other folks with the same setup are also experiencing this issue and that Google has recorded this info, that doesn't mean that a workaround is impossible.
