Got me a new router from my ISP, of course there were issues instantly! Having problems connecting to wifi. Called my ISP and they said there is a bug somewhere in the router or in android itself. The router is a ZYXEL P-2812HNU-F1. They said I needed to get a static ip adress to each device. I got my Galaxy S2 up and running in no time, however, my HP Touchpad is not being so friendly. It says I'm connected but I get the grey wifi icon. Tried to disconnect and reconnect but no result. Also tried to forget the wifi and so on but no result. Also changed to b/g since it handles /n aswell. I've changed the router channel. In addition, my TP have begun to reboot randomly often in very fast cycles. I've flashed the Supreme mods a few days ago and everything worked flawlessly with my old router. Could the Supreme mod interfere with this maybe? Anyone please, this is so frustrating!

The wifi icon color is blue when you're connected to the Google servers. I remember reading something similar to your situation, I'll post a link if I find it. Meanwhile, you've probably tried this, but in case you haven't, try turning the router off for a while, then turn it back on again. You might want to go to a later build, they're quite stable. I'm one of the lucky ones, only had any wifi issues once, and turning the router off then back on solved it for me.
Good luck.
Edit : Try deleting the Supreme mods, they might be the problem.
As you said, I've tried to switch off the router and put it back on but I tried it once again but no result. I've also removed the supreme mods but there is no difference. I still get the grey wifi icon. Maybe should try a newer build, so tiredsome though but maybe the only solution. Will call my ISP for a factory reset on the system aswell.
Edit: Managed to come up with a solution. My ISP wasn't of any help so I had to do something on my own. So, I changed the security to wpa instead of wpa2 and noticed that my tablet got connection! The thing is, I want to use the /n standard and wpa does not support that. So (again), I had to enable a second wireless network and luckily my router supports four. One network with wpa2 (laptop) and one with wpa (tablet). Not a pretty solution but it works!

I did read somewhere that giving the TouchPad a static IP address helped with a lot of WiFi problems, maybe its something you could try. I personally haven't had any WiFi problems so I have never needed to test it.

Made a little update on my previous post. The solution was that I needed to change the security on my network (wpa2 to wpa). But as you mentioned, I needed to set it to a static IP adress aswell. Up and running now, as I type at least
try running an atheros update. i also prefer wifi analyzer for connecting to wireless networks rather than the android wireless settings. It shows you detail and information that android settings do not. Lets you configure channel options for B/G/N and A. plus more. its avail in google play.
Hi i am having a strange problem with my phone connecting to my WiFi at home on my phone. I find it will not stay connected to my router. I put the WPA2 code in and my phone says connected then it forgets the network and asks me for the code again. My phone connects to WiFi at work so i thought it was my router but my computer and Xbox work fine still on-line. It just seem to be a problem between my phone and router. I have tried lots of things from hard resetting my phone to changing the security on my router and resetting it I am now at the point where i am at a loss and have no idea how to resolve my problem. I have updated the software on my phone but still no joy Does anyone out there have the same problem or able to advise
Thanks
Hi,
I can't find anything relevant for you, so I will have your thread moved to your device section. ?

I'm not sure but I read somewhere this is a bug in the htc software. You can fix it by having a wpa code shorter the 6 characters I believe. Or maybe try changing to other wifi security protocol

If your phone connects at work with no problems, than its not the phone. The problem will be between the connection to your router. If changing protocol dint work, you can try open network (No pass, just for testing) if connects then its the security.
You can also check in wi-fi advance settings "wi-fi frequency band" its set to auto.
As the title says, after update i am not able to use wifi. Connects and disconnects periodically. I thought that data connection may on so switched off mobile data off, but still same. I had factory reset also, no use. Can anybody give me any insight as to how to solve this problem?
No one know the solution to fix this issue?
I got the solution. change the wifi security settings in your router. change it from wep to wpa personal. Now my wifi is not disconnecting. O course you will need to change the password.and restart both your router and phone after changing I got the solution from lenovo forum

Thanks a lot, my wifi works now like a charm.
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.
Hello,
I upgraded my stock MI2 to android 10 and now I can't connect to any wifi. I can see the wifi, but I always get "Failed to save network".
Resetting all network settings didn't do anything...
Any options besides full reset?
Thanks!
I've got similar problem, can't connect to my home WiFi, but at work and at friends home WiFi works well. Network factory reset didn't help.
The problem seems to be at the handshake WPA2 at the moment with Android 10. Change your network to WPA and it should work perfectly. Let's hope this gets patched soon.
same for me. device also freezes quite often, feels like an early beta.
thanks for the hint!
Exactly the same issue for me;
* As soon as I updated to Android 10 on a stock Mi A2, my work, home and public WiFi access failes with "Failed to connect to Network".
* Changing wifi SSID settings results in a "Failed to Save Network" error.
I will try downgrading the home security to WPA.
Kent B
Honestly downgrading the security isn't an option for me. Can I roll-back to android 9 somehow?
I have the same issue. Channing the WiFi network's security settings has no effect. Anyone find a solution? Has anyone tried a factory reset?
after update my MAC has changed and by default it uses dynamic MAC address regarding security. I changed it to static MAC and checked my MAC filtering option once again to ensure the right MAC is set

In my case, I can connect to the home network but not the work network (Eduroam network).
I have also changed the MAC address from random to the one corresponding to the device but it did not solve the problem.
have same issue after Android 10 upgrade, any idea how to fix this wifi issue?
Did your router hide SSID? if so, manual input your SSID and type of network and the password. At the very bottom you'll see Advance Settings then chose Hidden Network to "Yes". If still not working probably there's was a problem during update installation. My Mi A2 doesn't have any problem after Android 10 Update.
after trying many things, only reset to factory settings finally fixed my wifi issue
Update from Late March 2020

Tried a number of things, including resetting all data stored settings, dropping down to WPA and even open (unsecured) network. Still no WiFi connectivity. WiFi apps such as WiFi analyser can see and engage with APs, but not connect.
The "Failed to save Network" error I suspect may be the issue ... each time I try to connect it asks for a password each and every time.
I just updated to the A2 March 2020 update, and this has not fixed the issues. Definitely happened immediately after the original Android 10 update.
I'll have to wait until things settle a little, then try a factory reset. Or a new phone
did you try reset complete phone to factory setting? it should help
I'm with the same problem! I just upgraded to Android 10 today and I can't connect to any wi-fi network!!!! I tried to restart my Xiaomi Mi A2, restart my modem, restart internet settings, add wifi manually, and other things and none worked
Same problem here after March update

My Wife's A2 just received the OTA Update to Android 10, which already contains the March update, and the same issue happened. Tried all the tips, nothing worked (changing the MAC to "Device Mac", resetting WiFi connections, Using static IPs).
The only thing that worked for me was setting my WiFi network (on my router) to use WPA-PSK(TKIP) + WPA2-PSK(AES) instead of just WPA2-PSK(AES) as it was configured before.
It seems there's a bug when using WPA2 (or AES).
Factory Reset fixed it for me.
After spending hours trying various options. I just did a factory reset and my Wifi has returned. What a performance, but wish I had done it earlier. Although it's a pain having to set up everything again, it wont take me as long as I have spent already trying different things.
Same issue here with the Android 10 update in April 2020..
No wifi networks seem to be saved and connecting simply does not work, I have a open wifi near me (payed hotspot) but a 'cannot connect' error pops up instantly when tapping it.
My home network asks for password but after entering it I also get the 'cannot save wifi network' and 'cannot connect' errors.
Pretty lame, I was planning a factory reset anyway but having to rush it sucks.
Will post results of factory reset here, but might take me some days. Especially with all the 2FA misery.
