[Q] Wifi/network issues (not dhcp related)

Im having some issues with my new galaxy tab.
Whenever I try to use wifi/internet I get alot of network errors/timeouts/dropped packets, no matter what app I use.
whenever that happens I have to press refresh/retry a few times and suddenly it works, after a few minutes it starts giving errors again.
this is not the already known DHCP error, i can connect to the network fine and receive an IP without problems. the problem is the connection itself.
i have already tried to change my routers encryption from wpa tkip to wpa aes, which seems to reduce the number or errors I get but did not fix the issue completely. when I tried to use my htc ad-hoc hotspot with the tab it seemed to work better, could have been coincidence tho
some info:
- its a branded tab from tmobile austria
- the firmware is t-mobile branded PDA: P1000BOJJ3 Phone: p1000xxid CSC: p1000maxjj4
kernel: 2.6.32.9 root at SE-S611 1 build froyo.bojj3
- router is in my room, so the range is fine
so what can I do to fix this? anyone else having this problem? also, why does it say "root" in kernel I dont think I have root access?
ps: your spam check is running amok, cant even use at sign in my posts??

I get similar things sometimes, not sure about the solution. What are the errors you get onscreen?
The root bit means that Samsung build the kernel on a machine that was logged in as root, i.e.: they're stoopid
You get used to the spam filter

It's possible if your in a highly populated area that there is too much contention for air space. There is a great free app in the market called 'wifi analyser'. Use this to test if another wifi is overpowering yours. Also, use the time graph tick away in the background to check for dropouts.
The fix may be as simple as changing the channels of your access point.

Try enabling XPress™ Technology on your wireless router (if option to enable it exists and your routers supports it) analyze your network to see if there is interference from other networks. Finally adjust your router to 802.11 G/N setting I don't think you need a/b.
Hope it helps

[Q] issue with darkrom 3.4

Hello
since installing 3.4 I have had issues with this rom however none so serious I jumped ship however I have problems with conecting to my home wifi which is causing pain...
I have set up wifi on my note as dhcp and my netgear router is also set to give ip address via dhcp however the note will only connect sometimes otherwise the message 'obtaing ip address' is shown then the connection drops to remembered and then Im back on 3G. I have tried various fixes including re-flashing the rom providing a static ip address. I have this issue with any dhcp network the note just will not connect all the time...

It happen even on stock to me mate.What I do is turn off wifi,go to browser and navigate to any site(yeah with wifi turned off still and data network off),when it gives you error turn on wifi and refresh the page.
I know its irritating but I have no solution and it works for me

still trying to find a solution to this. setting wifi sleep policy to Never seems to help I also deleted the dhcp_list file which forces the note to reconnect from scratch each time it connects to a known network rather than selecting it from the list. still not a full fix. seems to be a samsung thing rather than rom based. do the modem downloads available control the wifi functions or are they just for radio 3g etc as I will try a different modem to see if that helps.....

[Q] Cable modem/router: Wifi signal ok but no connection

Hi guys,
My phone: Samsung Galaxy S3, GT-I9305, Android 4.1.2
I changed the ISP (Germany: To Unitymedia) and are now supposed to use a cable modem which as well serves as wifi router. My hardware is TC7200 (Technicolor).
After setting up everything, the wifi connection to Win 7 laptop and Apple iPhone/iPad is working fine (also LAN connection to laptop of course).
The S3 showed a funny behavior: It is possible to establish a wifi connection and it gets IP address assigned. Default gateway, DNS server looks all fine. However, this is only the wifi signal but not an internet connection. It is not possible to reach any website.
The strange thing: If the google site is cached (from a different connection and then switching back to this problematic one) I can run a google search and get results displayed. However, it is not possible to open any websites displayed as results here.
I tried several things based on suggestions in the net, like restarting the s§, using static IP address, changing wifi ports, disabling wifi encryption completely, restart the router, factory reset the modem/router. Finally I performed a factory data reset for the S3 but this as well, like all other things, did not help. The phone was never rooted until before yesterdays factory reset, because I wanted to use Titanium Backup which requires root rights.
Of course, in all other wifi networks so far, this S3 works absolutely fine!
I am not sure if this matters at all, but with the new ISP I got an IPv6 IP address while before I had IPv4.
To be honest, it might simply be a hardware problem which has to be fixed by Firmware upgrade by ISP. This problem is sort of known to them and when I called in they promised a firmware update in November. But anyway, it would be interesting to understand more about it and usually there is a solution for everything Nevertheless, I couldn't find a solution in any forum yet.
Any suggestions / ideas welcome.
Thanks!

EDIT:
Post already moved.

Reads like wrong settings more than hardware .
WiFi is kernel you can flash a kernel .
But i would reboot router and phone then set up wifi with no security first .

Wifi Issue with Nexus 6

I have been doing research on this and it turns out that the Nexus 6 had issues with corporate wifi on 5.0. Corporate wifi is just wifi that requires a username and password to access if you do not know and this is the kind of wifi my college uses. Well hoping this problem would be fixed with 5.1 update I got the update and am still having the same issue it verifies the network but only says saved never connects however many tries it does its just a huge loop and this is getting very annoying. I dont know if there is something I should try to resolve this problem or will just have to stick it out until google addresses it. If anyone knows more about this issue please inform me because I have reached a wall with my research on this issue.

Yeah, ever since I updated to 5.1 I haven't been able to connect either, and I try through the Xpress Connect app like and it never works. I had been able to connect normally when I was on 5.0.1 before.

Hm, my cable company offers local WiFi and I've been able to connect to their userid/password-required routers, then use their network. Did this just a couple days ago when signal in a particular store was really hampered.
Maybe it depends on the particular router and/or configuration they use?

We had to update firmware on our corporate router for the problem to go away.
See my post here for more details: http://forum.xda-developers.com/showpost.php?p=59682044&postcount=12

LEAP authentication.
Try installing the hydra kernel.
I use it along with meanpop and have no problems connecting to LEAP

By username and password I meant one that the company or school gives you individually its not the kind of regular router login because at home I connect no issues but its the school wifi they even checked my account to make sure I wasnt blocked out of it and I was not. My fault for not being specific in the original post.

In my case N6 was able to connect to one password protected SSID without an issue, the subnet associated with this SSID is dedicated to provide internet access only.
The SSID N6 was having problem to authenticate with, was another SSID, whose subnet is bridged to provide access to both internet, and to corporate network.
According to Dell support, the Sonicwall router was failing to authenticate a connection coming through a bridged interface. I guess, N6 and/or Android 5.1 implements something new vis-a-vis authentication, that an older SonicWall firmware was not designed to deal with.
Immediately after SonicWall firmware update the problem was resolved.

Just wanted to chime in on this one... We have a corporate Wi-Fi as you describe (each user has a separate logon to the network) and I've not had any problems with Lollipop, 5.0 or 5.1. Not very helpful for you, but at least now you know it can work...

Issues with WiFi for certain apps.

Nokia 7plus India version. Not rooted. Have been encountering issues with certain apps over WiFi as the app doesn't load data on wifi just keeps attempting to load content. Twitter, Amazon, Instagram, yahoomail, all have issues. All of these apps work perfect on mobile data. But apps like whatsapp, kaspersk,flipkart, you tube, all browsers work well with WiFi as well as mobile data. So nothing wrong with WiFi as such. MAY month update from Nokia had this corrected, but June update brought the issue back. Currently on August security patch, continue to have the same problem . Anyone else facing same issue? Any fixes? Saw some comments in net from users encountering same problem

Unfortunately i'm tired of this problem as well

I am also facing the said issue in twitter and plx app when connected to wi-fi

Looks like it's common issue across Nokia devices. Shocking.
'Search WiFi issues with Nokia' on Google. So many people facing the issue and Nokia hasn't fixed it yet.

I am having the same issue on Android Pie beta. I tried the following to resolve the issue but it still persists!
1. Hard Reset my phone through recovery.
2. Hard and Soft Reset my Wifi Router.
3. Updated Wifi router firmware.
4. Reinstalled all the apps which were not working on Wifi.
5. Cleared Cache and Storage of these apps.
6. Changed Wifi router settings to IPV4 instead of IPV6.
7. Reverted back to Oreo 8.1 (updated upto July Security Patch)
8. Checked if these apps work on other phones on the same Wifi settings and found that it works perfectly!
None of these helped. In the end I have to shift to mobile data to check out these apps and its annoying!
Any other suggestions other than the ones i have tried above?

Learn going back to April security patch solves it. By the way how did u go back to June security patch?

I did when I reverted back to Oreo 8.1. After that I got 2 OTAs consecutively before I could even setup the phone upto June Security Patch. And then updated to July the next day. But the issue persists after the various updates.

After a lot of research into trying to understand the issues that I was seeing, I finally figured out that this was a IPv6 related issue. As it happens, in my case, it turned out that my router was causing the issue and not the phone itself. Please note that you may be seeing either the same issue or you may have completely different issue, but I hope the description below will give you some clues and directions that you may want to investigate.
The primary issue was that my router was returning a bad IPv6 address whenever a device connected over WiFi. I figured this out by running network diagnostics using the Netalyzr app from the Play store. When connected thru WiFi, this app reported a bad IPv6 address, but when connected thru a 4G LTE connection, it didn't report that as a problem. As a secondary check, I also used the IPv6 status widget to verify the network status when connect thru either of the connections. Again, this clearly showed that my phone was only on IPv4 when connected via WiFi, but was on IPv6 when connected vi 4G LTE.
Net, Net (no pun intended), some apps on the phone refused to work via the IPv4 address and required a working IPv6 address to work. Others were probably more tolerant and would fall back to work via IPv4 when they found a bad IPv6 address on the phone. Not sure if the apps should be made tolerant or the phone networking should be tolerant enough to do the IPv4 fallback for all apps. This is something that Nokia could investigate as a possible issue in the firmware.
Anyway, subsequently I checked many IPv6 related settings on my VDSL router (DLINK-224), but couldn't resolve the issue myself. I ended up calling my ISP (Airtel) and asking them about their support for IPv6. Initially, they claimed to support it, but later confirmed that for now, they don't support IPv6 for broadband connections. However, they sent over a technician who was extremely helpful and for no obvious reason, replaced my DLINK router with Huawei HG630. Again, for reasons not clear to me, this router started giving valid IPv6 addresses whenever a device connected over WiFi. My guess is that internally, its doing some IPv6 to IPv4 translation or tunneling, but at least the IPv6 address it was giving out were valid and working. Of course, as soon as my phone got a working IPv6 address, all those misbehaving apps started working and I have no issues any more. Interestingly, after the router change, ipv6-test.com tests now shows DNS6+IPV4 as reachable, even though it clearly shows IPv6 connectivity as 'NOT SUPPORTED'. In any case, as long as all my apps work well over both WiFi and 4G, I am a happy camper !
If you folks are still seeing these issues, please try the apps and sites I have linked above and see if you have the same issues. If so, you may be able to find a resolution thru your CSP or may be able to resolve the IPv6 address issue another way. All the best !

Thank you for the detailed analysis and your work around! I tried to change the required settings on my Dlink DSL 2750u router. I even tried to disable IPV6. But somehow it gets turned on automatically. I think its a problem with the router as you mentioned perfectly. I have contacted my ISP (BSNL) for some support, but I doubt they could help. Now only Instagram wont work. Even I reverted back to stable 8.1 with August Security Patch but still it wont work.
