Note 7 on Wireless Network - Vega General

Hi, when I log my Tegra Note 7 onto my wireless network it shows up as 2 devices, 2 IP adresses, 2 MAC adresses and 2 host names. Does anyoune know why this is? It doesn't seem to affect performance but my other Android devices don't do this.
Cheers,

Hi
i'm not sure if you mean that the device shows up twice on the network or the network shows up twice on the device?
my Virgin router has two network id's and passwords because it has 2.4ghz and 5ghz modes. ( i set up the network id's and passwords myself). my N7 2012 only shows the 2.4ghz id but my N5 shows both and will connect to either
dual band wifi isn't supposed to be available on the Vega 7 (i had the original Vega before my 2012 N7 and am looking at buying one next time it's sub-£100 so i don't have any device to test yet) but i presume that could allow it to connect to both at the same time and give the Vega two addresses on your network?...

Can't connect to wifi - "avoided poor internet connection"

I've been having problems trying to connect my friend's Nexus 7 (32Gb) to my home wifi. I tried 4 (yes 4) wireless routers, and it refused to connect to any of them. It would prompt for my (WPA2) login credentials, then spend a few minutes trying to connect, then give up and try another access point. It would mark the AP just tried as "avoided poor internet connection".
The routers I tried were:
- Belkin Play Max N600 HD
- Buffalo WHR-G54S
- Draytek Vigor 2920n
- O2 Broadband wireless box 5
The signal strength from all of them was shown as excellent. I tried the O2 wireless box with WEP encryption instead of WPA2 and that didn't help.
I was able to connect both a Samsung Q330 laptop and a Galaxy S3 to all of these routers, so they all appear to be working fine.
As I'm shortly planning to buy a Nexus 7 I'm keen to understand what sort of problem might stop it connecting to my routers!
Any ideas?
avoided poor internet connection
Hi,
I have the same issue and i foud that it is due to the inferior frequency of my router wich is 2.4ghz.
so i you did found a solution please share it,thanks in advance.

All routers use 2.4 GHz unless they are branded/advertised as being 5 GHz. The Nexus doesn't even support 5 GHz. The warning is more about the actual internet connection anyway. As for removing this warning, you can easily disable it under advanced WiFi settings.

I subsequently acquired my own Nexus 7 and had no problem connecting it all of the routers that my friend's Nexus 7 wouldn't connect to. I'm guessing that I was running a newer ROM. I still have no idea why my friend's unit wouldn't connect
Your friend should return his faulty N7 for a replacement.
If you can access the router, do a reset or reboot, sometimes a refresh would get the "hand shaking" working again, switch to an alternate wireless channel as it could be interference from other nearby routers.
after some research i found this .
and for the "avoid poor internet connection" in the advanced menu ,in 4.1.1 the is no such option in the menu .

Your custom rom is not the same as the OP. There is no option you suggest on a stock rom.
I had the same problem with my PC...
usually the problem is with the router, restart the router,

SOLUTION
Figured it out...go to the WiFi settings, hit the menu key and choose "Advanced", and uncheck "Avoid poor connections".
There are lots of android phones without the above mentioned option(The place where you can uncheck your "Avoid poor connections" )
If you're in that case I've got an alternate for you
1. run command prompt and type ipconfig
2. note down your ip address
3. now what you do is change the last digits after the last point and give the command
ping 192.168.1.xx(changing the last digit or last two digits)
it'll say pinging and BLAH BLAH BLAH
It'll give details about the sent and received packets of data
And also LOST packets
NOTE: If the lost =0( 0 % lost)
4. Then note down the ip address which you've given after the command ping **192.168.1.xx**
if the lost= (100 % lost) or may be some other percentage of lost... it means there is some loss of data packets
so never note down that..... repeat the process 3. changing the last digits of your ip address
5. Now once the lost percentage is 0 %
6. go to settings->Wi-Fi-> And long press the network to which you wanna connect your device
7. Choose modify network
8. Enter the password(If there is any and do not press save)
9. Enable show Advanced options
10. Change the ip settings to static
11. Enter the ip address which you've noted down in steps 3 & 4
12. Enter the noted ip address in the ip address
13. Also Enter the gateway address in the column below which you find from your cmd prompt giving the command ipconfig
14. The network prefix length ,DNS 1 And DNS 2 Will be automatically assigned
15. Now click Save
Thats it .......You're Done
incase if the Avoided poor connection occurs again repeat the steps from 6 till the end giving the same ip address which you've noted down
ENJOY ! ! ! ! !
I've fixed it
Hello.
I fixed this bug, it isn't poor conection... it is an error about dhcp server in the android 4.x
First you need to download and install ipconfig app from aptoide
So you need to try to conect to your network, while it is showing obtaining ip adress, you should go to ipconfig app (be as fast as posssible)
Finally you should find your ip number and your gateway, if you don't, click in refresh.
Now go to settings and long click into your network, so click in advenced settings and change dhcp to static IP, here are the recommended settings:
IP- get in ipconfig
Gateway- it will automatically set, the most used is 192.168.1.1
Prefix- 22 or 24
Subnet mask- 255.255.255.0
Dns1- 8.8.4.4
Dns2- 4.4.4.4 (no need to set)
I wanna develop an app to do it automacally, but I need help... I'm pretty noob, I've got only 14 years old
Edited: Oops, I didn't saw your solution, anyway it doesn't work on all routers cause some routers are set to another ip
I'm glad to help you

[Q] 4.2.1 unsupported wi-fi?

I realized that my University's wifi somehow does not support 4.2.1
I've asked them about it, and they said 4.2's kernel might be different and it might not recognize the wifi.
What can i do about that without downgrading? (My device is rooted.)
Thanks.
Perhaps you should say a few words about your University WiFi. Same goes for what you have done to your N7 (as you stated that it is rooted). Maybe you could mention whether or not you personally had it working with a 4.1.x-derived ROM on the phone - reading between the lines it sounds like that might be the case, but it isn't clearly stated.
"Does not support" is not very descriptive.
First - does the WiFi scan on the N7 display the network? (e.g. the N7 does not support Ad-Hoc networks, so they won't even show up in the first place)
What details can you provide about the WiFi network?
- Ad-hoc or Infrastructure mode?
- is WEP/WPA/WPA2 in use?
- if Y to above question, how is key distribution performed?
Are there any other relevant symptoms, such as the N7 connecting, but then fails to get an IP address - or gets an IP, but still acts as if not connected?
If you are convinced that it is in fact a 4.1.x vs. 4.2.x issue, could you not just install a 4.1.x-derived ROM?
Note also that the n7 does not support WiFi N band. Make sure the university provides G support.

The N7 absolutely supports 802.11 b/g/n. Take a look at the tech specs in Play store.

I know that, Wi-Fi works with Galaxy S 3 having 4.1.1
And the setting used to access Wi-Fi are as follows:
Security: 802.1x EAP
EAP Method: PEAP
Phase 2 Authentication: MSCHAPV2
... And I put-in my username and password in the followings.
I tried to connect, it shows the signal much weaker then it actually is, then it tried to connect, but just fails...

That's all well and good, but it doesn't necessarily mean that 4.1.x vs. 4.2.x is the cause of things. Different hardware, different OS, and presumably different WiFi radio hardware and firmware. Could be any of those things, the OS being one of them.

Association and Authentication to a WiFi AP have lots of moving parts. It is possible that the problem is with either of them. (My WAG would be the authentication process) Without a super-geek that can help you with wireless sniffing (to see if the fault location can be inferred), or your campus IT help desk being able to look at authentication logs, you don't really have much recourse but to:
- do something drastic (e.g. install new ROMs)
- experiment with the settings in the WiFi "Add network" page, and look to see if you get any meaningful or diagnostic messages in the system logs. I tried it just now, but I don't have an 802.1x AP available to test (a failed PW, for instance) with to see if anything diagnostic shows up in logcat. Is it possible that it is just a bad password entry? (I have had problems when I cut and paste in android with various apps inserting a leading space ahead of the paste).
The 4.1.2 factory image for the WiFi N7 (grouper) is still available from Google - I think the form in which they provide it to you needs to be flashed using fastboot though, and managing that seems to cause newbs trouble. You might want to just find an older ROM which is based on 4.1.x and try it to see if it fits your hypothesis. (If you fool with a factory ROM install, make sure you have backups of EVERYTHING first).
Good luck
I have taken my nexus 7 to IT they looked into it and they said its possibly that it not compatible with 4.2.1
I guess downgrading to 4.1.2 might do trick, but I also don't want to leave the awesome features of 4.2.1
I guess I will firstly try different kernels and see if they change anything.
This thread contains reports of problems with both 4.1.x and 4.2.x N7's
I suspect that just reflects a diversity of different wireless networks; but anyway - see the logcat entries with "I/wpa_supplicant" in them? Your tablet (on 4.2.1 or whatever) might have similar things in it that gives clues as to where the errors occur.
You can get logcats with adb - or failing that, there are free market apps you can get which will dump the logcat to a file of your chosing.
Good luck
Thanks I will take a look at those.
Miss-statement on my part earlier. Nexus 7 does support 802.1n operation - but only in the 2.4ghz band. 5ghz is not supported. My router supports both - and the faster ssids are not even visible on the Nexus 7.

802.11n specifies channel bonding techniques as well as optional use of the 5 Ghz radio band.
So, marketers can safely say "Wifi N" or some such - as long as the hardware/software can do channel bonding (but possibly not operate in the 5 Ghz band).
Here's Asus N7 Spec Page, as you see they do not mention 5Ghz Wifi.
My thinking is that if the hardware had it, it would also show up proudly in the specs.
A to the Q: hardware.
It now occurs to me that Zhoene earlier had said

A university setting probably would be a WDS (Wireless Distribution System) with many AP's. Possibly Zhoene was sitting close to a 5Ghz-only AP, and "seeing" a multi-band AP at a good distance away? Sure would be consistent with rmm200's observations on his/her router.
Also, I see reports of 5 Ghz service achieved on Galaxy S3 (Zhoene prev mentioned)
Perhaps this is exactly a 5Ghz AP vs. Nexus 7 issue.
And, oh crap after all this writing I did a search
http://forum.xda-developers.com/showthread.php?t=1777431&highlight=5ghz+802+11n&page=3
Zhoene you could ask your campus IT if there are any A/B/G- or B/G-only APs in their network & see if you can connect at those locations. If it was something weird like Beacons only in 5Ghz-band channels (I think that would violate the IEEE specs), then you could have been trying to connect to very remote APs - all the while getting clobbered by other devices sitting nearby doing 802.11n in the 2.4Ghz band, but also the nearby AP as well if it was operating in multi-band mode.
Thanks a lot for all the information, I'll try to find out what the problem really is using those informations.
Some of this talk of networking is over my head, but what I would try is flashing a 4.1.2 ROM/image and seeing if that fixes it. 4.1.1 had a bug that prevented the Nexus 7 from connecting to WPA-Enterprise networks, which is what my university uses (I know because my Kindle can't connect to it). 4.1.2 fixed this, and my Nexus 7 (on 4.1.2) can connect to my university's network. I have been rejecting the update to 4.2.1 after hearing about issues, so I don't know if it works with 4.2.1.

[Q] New Nexus 7 can't connect to wifi (couldn't sign in) help..

I just bought a nexus 7, came home and spent 3 hours trying to connect this to wifi and it doesn't work... meanwhile i have 9 devices connected wireless that never had problems... -_-
when i first start my NEW nexus 7 and get to select wifi page.. i select my wifi (which shows 3 bars) i enter my correct password and it just loops from "connecting.." to "obtaining ip address" over and over after hour of that i got fed up and tried connecting manually .. i tried using ip/dns from ipconfig in cmd didn't work.. i went to my iphone and copied the wifi adress settings to my nexus 7 and it said connected
but when i went to next i logged into my gmail account and i get this
"Couldn't sign in
Can't establish reliable connection to the server.
This could be a temporary problem. Try again or connect to another Wi-Fi network."
i have no idea what to do ARGGGG HELP PLZ!

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?

My galaxy s2 is working and also samsung notebook.. but there is a problem in s4..... i really dont know .... what does it cause by?
my wi fi modem's model is "inca IM-205NX" can you google it? i cannot enter a website link on forum because of new user
i have some news i guess i will solve the problem
when i enter my modem surface, i see modem passward.. as i write before, my modem is inca, and security type Wpa/wpa2 psk..
when i change security type from Wpa/wpa2 psk..to non-security, i can access my wi fi connection. i mean if there is no password on modem, i can reach but it can be dangerous, hackers can intrude....
i will change my modem settings until solve wi fi problem and i will notify you
okey the problem has been solved guys....
i have entered my modem's surface and changed Security type from WPA*Wpa2 psk to Wep and restart both devices
Web is not so secure rather than WPA*Wpa2 psk but the important point is that s4 is working with wi fi

So, you could enter the passcode in hex. There's a small chance this could help. You'd have to do the same on the phone obviously as well. Actually, I just realized I don't have that option on my phone (and old Dinc2) so may not even be an option.

Galaxy S4 WiFi problem too
I dont see why this went to a router issue...?? I am having the same problem with the WiFi on my one day old S4. It is almost like the signal freezes because it still shows I am connected with a strong signal but nothing works. I have never encountered a problem before with any other devices(S2, S3 Note2, multple tablets) and saying that it is a router issue and saying that i have to disable security or get a new router is not a solution!
I have seen this same post on multiple forums and yahoo answers but nothing as far as a real answer to the issue or to what is causing the problem. PS...there are two new S4's in the house and both having the same issue....
I'm having the same problem, Brazilian S4, at my girlfriend's house, I could not connect to Wifi, the modem is a Fiberhome HG110-B.
Same issues here unfortunately. I think it's the router. Wifi at work is fine. Wifi at home has issues. That's a bummer because I love my Amped Wireless Router at home.
Same issue
Hi Guys,
So my S4 is also just a day old, and I am having the same issue, tried everything, only connects when I remove my wifi security(obviously not ideal), I am brand new to Android, jumped ship from Apple .
I dont have then exact model number with me now(at work) but my router is a trendNET something something 335.
All my other devices connect to my wireless without issues accept my S4, it is very annoying, we are still being screwed over by our Mobile Operators in South Africa, hence the fact that my wireless is so important to me..
Thanks for the help!
actually we have to wait for new update... hopefully samsung will solve that problem...
i am now using with low securtiy (wep) but i don have any choice now
My fix
My FIX
Hey dudes and chicks,
I used to have this problem too with my s4. Connecting just a minute or two and after it would just lose connection. At first i thought it had to do with something from the hardware, but i figured that was not the problem since it did have a stable wifi connection at my uni.
So the problem for most of the people is within the router. Here's how i solved it for me. (I have a Sitecom Wireless Media Router 300N WL-350 with 2.4 and 5 ghz, so the steps might differ a bit if you have different router)
-------------------------------------
1. Login to your router
2. Go to the setting for wireless 2.4 (probably radio 1) (For Sitecom go to tab Basic> subtab Wireless 2.4 GHz)
So what i changed here is the 802.11 mode. (there are several modes like: just 802.11b, just 802.11g, just 802.11n, mixed 802.11b and 802.11g, mixed 802.11g and 802.11n ........)
>>> I Put It On: "mixed 802.11g and 802.11n"<<< (it used to be on mixed 802.11b, 802.11g and 802.11n)
3. Secondly i disabled Auto Channel Scan. This allowed me to select a Wireless Channel (frequency/channel).
>>>I Chose the highest channel ("2.472 GHz - CH13")<<<
4. I used to have the Transmission Rate at the option "best (automatically)"
>>>I changed this to the option: "54" (Mbit/s)<<<
5. I have channel width at the option: "auto 20/40 MHz" (but it always used to be this one)
Furthermore i have the following settings:
> Security mode: "WPA - Personal"
> WPA Mode: "WPA or WPA2"
> Cipher Type: "TKIP and AES"
------------------------------------
Now running stable for more than 6 hours (incl heavy use like youtube and movie streaming from samba server). I believe that step 2, 3 and 4 are the most important ones. If this does not work immediately, try to play a bit with step 3 and 4
Im not that technical but if you have questions feel free to ask.
Help out your fellow Galaxy mate by letting them know whether this worked or not ;-p
Ill also post my fix at this thread http://forum.xda-developers.com/showthread.php?t=2253471
Greetings,
ps sorry if i made some grammer mistakes, not my native language

I have two Nexus 10 tablets. 5GHz WiFi is working on one of them but not the other.

Both tablets are running stock Android version 5.1.1 build LMY49J
I'm just using them in my house to monitor some security cameras. That's basically all I use them for. The WiFi they both connect to comes from the only router in my house. I've always had that router (Asus RT-AC66U) setup with a different SSID for the 2.4GHz and the 5GHz.
The first Nexus 10 I bought used about a year ago and it has been able to connect just fine on both the 2.4 and 5ghz signals.
The second Nexus 10 I just got off of eBay about a week ago and it cannot connect to the 5ghz wifi signal. I thought it initially did because that's the network I chose to connect to when I first set it up and it was working... though the SSID is different, I do use the same wifi password on both of them. I don't know if it can recognize that and just switched to the 2.4GHz SSID or if I was dreaming that it ever worked at all on 5.
Anyway, it's definitely not connecting now. It will just say "Obtaining IP address" and never connect to the 5GHz. It has no issues with the 2.4 signal though.
I had searched and found a lot of threads and tried many of the different options suggested like switching my router to only broadcast on certain channels, etc.
I'm just wondering if there is something I missed or if it's more likely that there is something wrong with the hardware on this "new" tablet I just started using.
