wifi problem after ics update p6200

i'm experiencing the following problems after ICS update:
wifi connects only once after booting the device that too for few minutes then neither connect to any network nor scan, and it shows the wifi network not in range, then need to restart the device in order to connect to wifi again
is anyone experiencing the same problem?
is there anyone have any solution for this?

Same here.
I did install ICS 4 times (back to HC even) and had the same problem just like you said.
And CSC change from ZTO (Brazil) to KOR (Korea, I think) as Kies shows.
Tried WiFi Fixer from Google Play but no luck. Keep reseting wifi all the time.

it looks like no one have found a solution, i've been trying very hard to fix this issue but no use, still the same

GT-P6200L (Brazil) here.

Don't worry guys! We're working on a fix!

I use WIFI Manager for now and it's working for me.

Thank you very much!
Could you tell us what is causing the problem?
Could be 3G band (900 or 850 MHZ "L" model) or who knows 2,5 or 5 GHz wifi ap's frequencies... I'd like to know the diagnosis

I have the same problem... :-(

That's not the problem, I think, because I have a brazilian model P6200L and it works great, wifi is fine, but some people with the same device are having this problem, I've told them to flash the baseband/modem from a brazilian FW and it still not working.

Same problem here in Malaysia. Wifi doesn't work at all for me and it is a big problem since wifi is my primary internet connection at home. When I switch wifi off and on again it detects my home wifi with full bars and when I try to connect it immediately goes Not In Range. I've tried wifi fixer but all it does is constantly resets my wifi which doesn't help at all. I need to downgrade again..

I saw someone commenting about using static ip to solve the problem. As in my house I have two routers and in all of them i did set static ips prior to ics i didn't get that wifi problem.
But using dhcp I can reproduce it.

Doesnt work with static ip. Flash again ics and doesnt work
Any solutions?

It seems that our ics version of tab is quite picky on the type of wifi router that it would connect. my temporary workaround is to have the wifi channel at the router fix to 1 channel instead of auto..my router is set to 1, seems to solve the wifi problem..you guys should try it..

I did something similar, I changed the wireless region from Africa to Europe on my wifi router, it seems to help but my wireless stops working sometimes and then just reboots on its own.

I had similar problem with other device, so this thread helped me out:

this would be usefull as well:

After root I will bac to the HC and wifi work ok.Again,I flash Austrian ICS and one diferent is here...my CSC code now is EUR,no more KOR.I hope that is a problem.

wifi issue

Okay the wifi router is in the same room 4 5 feets away from phone but still i only get one bar and when i go kut of room i dont get wifi connection at all.is this a hardware problem or what?

Reset
Do you have the latest 4.4.4 update? However, try a factory reset of the phone it can help :good:

Yes i have 4.4.4 and i have tried factory reseting it.

When none of such things work it might also be a setting of your WiFi router. Some of these routers have an option wich allows you to set the strength of your WiFi signal.
I'd suggest you see whether other devices also have the same problem. If this is the case: Try to find a setting which allows you to set the strength of your WiFi signal. If not: It is probably a hardware function since I have not heard any other of such problems with a Nexus 5 on 4.4.4, so I'd suggest you should send it back for repair.

Brand New Nexus 5 Doesn't Connect To Home Wi-Fi [URGENT]

I bought a nexus 5 to replace my galaxy s4 which died a couple of days ago.
My home router is a Netgear D6300 and everything (pc, tv and phones such as iphone, samsung and nokia can connect just fine).
My nexus 5 was delivered today and i spent the last 5 hours to get it working with my wifi but NOTHING worked (and, i'm not joking, i got to the point of almost throwing it out of the window).
I tried enabling SSID broadcasting, changing "security options", changing channels, disabling 5ghz network, i also enabled the guest network with no protection but nothing worked.
The only thing i noticed was the when using particular channels (5-6-7) the phone would say "connecting" for a few seconds but then it would go back to "saved,protected with wpa/wpa2".
I also changed some wifi settings on my phone (i disabled wifi optimization and i forced the phone to use the 2.4 ghz network only)
Sometimes it stays on "saved....." and doesn't even seem to try to connect.
After a while i tried creating an hotspot with an iphone 5s and my nexus connected in a second and everything was working.
So the problem should be in my router settings but i already tried everything (and besides everything else but the nexus works just fine).
I'm really desperate because i use this phone for work and i need to get this working asap.
I also managed to update to android 4.4.4 using my mobile network but i can't update to lolipop because it would use all my remaining 3g network data.
Btw i did some heavy modding on my galaxy s4 so i'm not a newbie to android.
I'm also willing to pay for support but to be honest i'm really disappointed that such and "acclaimed" phone has problems connecting to a wifi network that works with basically everything.

Sorry if I missed it in the post, but did you reboot the router.

Yes but it didn't help.

I've had 4 N5's in my possession over the past year or so, and not a single one had any issues connecting to any WiFi network, including Netgear routers. Your problem is either specific to your particular device or your router and not with the N5 in general. I assure you, the N5 deserves all the praise (and criticisms) that it has received.ave you tried a different router? I know you used it with your iPhone's hotspot but I mean an actual router? Also, have you tried resetting your router to defaults?

Are you using MAC filtering on the router?

I just tried a dlink router on my home network and everything works!!!!!
But i want to understand why my D6300 doesn't work with the nexus (its configured the same way as the dlink).
Any suggestions???
In the meantime i'll reset the D6300.

If your router is handing out DHCP addresses it may have run out of addresses if you have many wireless devices connecting infrequently. But I would thing a reboot would have cleared that up.

Wifi connected, but no internet access

I get connected (no internet access) from time to time when I automatically connect to my school's network. It connects automatically and works in some buildings and doesn't in others. Turning wifi off and on fixes the issue. However, it is annoying to keep doing this. I had this issue on EMUI 4.1 and 5.0 (through charles and dload) so I don't think it's the version of android. Is anyone else having the same issue? Could it be the school network's issue? Thanks.

Have you tried using a different internet browser?

Sorry for the late reply. It's the WiFi in general. Apps that require Internet don't connect either. I did a factory reset and that didn't fix anything.

I have similar problem. When I first got my phone it was on firmware B160 without any problem. I updated to Nougat using firmware finder and the problem started to surface. I rolled back to B160 using their rollback tool, which then got updated to B162. It's much more stable than Nougat but not as good as the original firmware that I was on. Each time I had done factory reset after the update to make sure I am not in some dirty state. (L04 variant)

I have similar problem sometimes on my honor 8, it shows up excellent internet connectivity but failed to lunch apps like facebook or youtube etc(says no internet connection) while other hand samsung A8 run just fine with same wifi network at same time. I have done factory reset but nothing miracle happen still same problem. Frustrating....

If it's been on both 4.1 and 5 its either a hardware issue or the school network is bad

if the wifi works fine when you connect it to different wifi's then its the school network not much you can do. ps you wrote you have the problem from 4.1 to 5 in your OP.....

I have restarted my phone several times, but not the AP because it is at my work and there are about 50 AP's all over campus and I doubt they will restart them for me lol. Amazon sent me a replacement phone as well so now I have 2 phones doing the same problem, just at work.

Then the problem is with the router itself. On my experience, some routers will let you connect but will not give you an internet connection.

Definitely the issue is from the router

There was this point where my laptop can connect to the router but can't connect to the internet. After a few days it got fixed automagically.

Have you checked to see if your internet connection is active? If it isn't then you would need to contact your ISP for more assistance with this issue.

Sticky or Slow WiFi issue...?

Hi Guys,
My return to HTC from the Rezound days to the U11 have been less than smooth, it seems. First I have the strange SD card corrupt issue... And now I've got this "sticky" WiFi issue...
Let me try to explain:
So, I'm on Stock phone, straight set up as I got it from Amazon. My Internet bandwidth speed tests around 250mbps on an average. And the speeds remain the same when I experience the issue. Essentially what happens is that randomly my internet starts to "stick" meaning, I'd click on a link, it'll take forever and a half and then the page loads out of nowhere. Similarly, I'd be syncing files to Google Drive and my file upload or download starts crawling ?...
The fix: Toggle WiFi on and off and starts flying again! I haven't noticed the issue while on data (I think)...
I have optimizations off for WiFi. WiFi stays fast on other devices... So I'm not sure what's going on? Anyone else experiencing this?
Thanks!

Haven't experienced it for now on 11.
WiFi was something "messy" on my 10, but all good so far on 11.
Might be some router compatibility issues, from top of my head and without first morning coffee see if it happens on both 2.4 and 5 ghz frequencies and if you can disable ipv6 on your router..

hi. i have the exact same problem as you but only on the 5ghz band. no option to select just 2.4 GHz band is a letdown. i use a virgin media hub 3.0 CH7465, ipv6 in stateless mode. had to disable 5ghz band from router to use the phone on wifi. no issues with mobile data. another issue, unrelated, is the vibration feedback on key press every now and again.

Thanks for reporting and sharing, friend... I'm wondering why more people aren't seeing this or we just got a bad unit? Hopefully HTC finds out and does something about it... ?

Hello !
I am Naphtaline, owning a Sony Xperia XZ Premium and we are experiencing some of your issues there too.
It looks-like the problem could be related to Snapdragon 835 or Android Nougat but we can't be sure yet.
While our problem are not always exactly the same as you, we can say that it could be possible that there are Wifi issues on every snapdragon 835 based device yet on the market.
So, I made a survey to help us understanding this problem. We could then send the results to our brands to help them resolve it.
Please share this link to every people you know owning a flagship device, even if they don't experience the issue. This is very important !
If there are moderators here, if you could make a pinned topic about this survey, this would be marvelous !
https://goo.gl/forms/xePus2lCrjrBjk9b2
Thank you !

this issue is hard to replicate, I tried doing 20 or so speed tests yesterday trying to get it to fail but wouldn't...I know in the past when the issue was present, I switched to 2.4 with no change...I don't have this issue on most routers, only my home router (TP-Link Archer C7) but there again, the issue is so intermittent that it's possible it could happen on other routers but just not noticing.

Pretty sure I've been having this issue since day 1, but I'm trying to tell myself it's just my router, which it's not, as it happens on any wifi network. Also, phone suddenly decided to drop my Verizon signal, and now it won't reconnect. HTC has no fixes for either issue, and Verizon says it's HTC's fault for the signal. Definitely my last HTC phone.

With 5Ghz, if i go to a room little far from where the router is, it would not work but the Speedtest would show amazing speed. Whereas the 2.4Ghz works fine in that room.

FWIW guys the dropped connection effect is happening on my 2.4 SSID as well... Only, momentary fix is toggling off and on.... Have any of you tried a replacement? Maybe we got flawed units?

I am also experiencing this issue and it's driving me nuts! The quick fix is to toggle WiFi on/off, but I shouldn't have to do that.
I have the Xfinity XB3 router, but I do not think it's the router because I also have an S7 Edge where I am not experiencing this issue. I'm going to try using the 2.4 SSID, but from what I've read in this thread so far, it does not sound like that's going to help.

I too am experiencing this issue on the 5Ghz channel of my router. It seems to work initially, but only after a few minutes, it starts to have connection issues. When I switch to the 2.4 Ghz channel, it works just fine, always, no connection issues whatsoever. I just did the survey. Thanks for compiling this, I hope a fix is determined. I have the US Unlocked version, Viper U11 1.3.0 w/ Magisk v12 and module v1.10.1.

The problem is wifi drop-off. Even though the device is showing a good signal the data throughput is weak. If you move closer to the router the wifi will jump back into life. Its due to not having an iso standard for signal strength displays.

Same here..

For me it happens only with my home router networks (Linksys WRT1900ACS).
I found that this drop issue only happens when I'm far from my router when the signal is below -65dBm and only if the 5GHz network is on 80MHz-bandwidth and 2.4GHz is on 40MHz-bandwidth.
Lowering to 40MHz for 5GHz and 20MHz for 2.4GHz solves this problem completely for me.
Two important notes:
1) This behavior only happens with the U11. With other devices like the G6, iPhone 6s and etc. everything works fine at the same time when my wifi networks are on 5GHz 80MHz and 2.4GHz 40MHz.
2) On other 2.4GHz 40MHz-bandwidth networks that I've connected (other than my home's) I don't experience this drops at all with the U11, even when I'm very far away from the router and the signal is very weak.
So this problem seems to be only between the U11 and some routers on some configurations. Very strange
