Hello forum members.
I want to share with You My Mi5 Pro WiFi problems, hoping someone can give advice so i can use my Mi5 Pro again.
The phone's WiFi has some issues:
It scan and display all networks, but can't connect to 2.4GHz networks.
It connects and work fine with some 5GHz networks. Also connect and work fine with 5GHz hotspot networks.
Bluetooth is working fine.
MiDrop can scan, but can't connect and transfer.
Hotspot is working only on 5GHz mode. On 2.4GHz can't share or connect to other.*
What I have tried to solve the issues:
Reset the phone.
Update the phone.
Flash other MIUI.
Unlock and flash other Android.
Rooted the phone and changed the WiFi MAC address (on MIUI).
Erased and flashed the modem (NON-HLOS.bin)(on MIUI).
No changes after all my attempts.*
And also, after all My attempts, I have noticed something. When I try to connect to 2.4GHz network (unsuccessful of course) and leave the WiFi on or off (the WiFi is not connected) , the phone's battery is draining very fast. If I connect to 5GHz network (successfully), and after that turn off the WiFi,**the battery is not draining fast.
If someone have any advice, or something I can check or share more info, I'm here and waiting.*
Thanks.
PS:Correction, 5GHz is not working with any router. More specifically, it's not working with most routers.
Maybe it's hardware problem. WIFI antenas disconnected?
Maybe, bit i hope it's software.
When i remove the antennas there is no wi-fi networks even detected, or only the closest ones are shown very weakly.

I have an unrooted OG Droid running on stock Froyo (2.2.3). It's off-contract, but I have been using it by connecting to my wifi router (Netgear WNDR3700). Everything has been working fine until Friday when it stopped connecting to my wifi router. I tried reconnecting, but it cannot seem to find the router at all, even if I'm standing right next to it. My router does not appear on the list of available wi-fi networks when I look at Settings -> Wireless & networks -> Wi-fi settings. The strange thing is that it seems to pick up all of the other wi-fi networks from my neighbors without any problems; it just can't seem to find my wifi router.
All of my other Android devices (Nexus S, Evo 3D, Galaxy Tab, Logitech Revue) can find and connect to my router without any problems. It's just as though the router doesn't even exist from the perspective of the OG Droid. I haven't made any recent configuration changes on any of my devices or router. My other wi-fi devices (laptops, printer) don't have any issues finding and connecting to my router either.
I've tried rebooting, pulling the battery, etc. without any luck. Any ideas?
By chance did you unplug the router, my og DROID loses wifi sometimes and even though phone sees it won't connect but usually resetting router gets it to reconnect.

I haven't done that yet, because as far as I can tell, the router is working fine. The issue that I'm seeing differs from yours as the phone doesn't even see the router right now.
It's a bug in Android. Delete all the remembered wifi accounts on the phone and then you should be able to scan again. Once you scan, it should pick up the router again. Had this happen on a couple different android devices.

I gave this a try, but it didn't work. I can still see all of the other available wi-fi networks near me, but not my own router. Any other thoughts?

I've had this with my router whenever i reset it.
its because there are too many routers in your area on the same wifi channels . change the channel your router is on until its one with less or no routers on it and it will appear eventaullly.

I have same problem with you.
My LWW cannot find/detect the home wifi, but another device (laptop and samsung galaxy mini) can work well with the wifi network.
but my LWW can find another wifi network except my home network. but sometimes when I don't use the LWW for long time, and when I started to turn the wifi on, it can work well. but after I stopped the connection and start to use the wifi again, it cannot find the network again
I just had the same problem and fixed it.
Sometimes routers are configured to select and use the less crowded wireless channel. That can cause your wifi to eventually use channel 12 or 14. Like sleepyguy007 said, it is more likely to happen if there are too many wifis in the area and all channels are crowded.
As far as I know, Android devices are by default configured to scan only up to channel 11. So if the wifi is in 12 or 14, it will not be recognized.
Go to the wifi config screen, where all the networks are listed. There, with the menu button, go to "Advanced"->"Regulator domain" and set Android to scan all 14 channels, that should do the trick.
I hope that is the cause of the problem and you can fix it... Otherwise it could be a bug, and the solution may be harder
I'm so happy & surprised!!!
I had same problem and with your helps(phobophille & sleepyguy007) my problem solved:laugh: :fingers-crossed: :good:

XPERIA Arc S
my device is not showing any network on my device to connect wifi.
i have tried everything but the problem is same . not a single network is appearing in my device. all others are connected to the same. in my phone in advanced setting it is showing ipv4 address is unavailable. plz suggest something.
Hi folks !
Recently I started to experience some troubles using my WiFis connections. The problem is simple, the connection drops, the WiFi network disappears from all the devices, and a few seconds later it comes back.
At first I thought it was a problem with the router of my work. But then I started to experience the same things at home. Then I decided to test the WiFi without connecting my Razr i to it and it worked like a charm. Now, as soon as I connect my Razr i to a WiFi, it crashes a few seconds/minutes later and keep doing it until I disconnect my phone from the WiFi.
Did someone experience the same thing ? Have you any idea for solving the problem ?
Thanks anyway.
PS : I only use 5Ghz WiFis. I'll try with 2.4 soon but the 5Ghz compatibility was one of the reasons why I bought this phone...
We have also issues with our WLAN at home, which is sometimes (but not always) very unstable in connection with a Samsung 5 Laptop (regular reboots shortly after activating the laptop Wifi).
I did not experience this problem yet with my Razr i, but I will keep it in mind over the next days (we have a complex setup with several computers, phones and Android entities based around a Fritzbox 7390, so error identification and validation takes very long and is not finished yet).
BTW - if you look for help here, please specify your WLAN router in detail as well as your provider and general IT-setup.

Well ! Thanks for the reply.
My router that provides the two WiFis is a Cisco Linksys WRT61N.
My setup is kinda complex but works well. Got another router provided by my ISP, which is the DHCP server. This router is connected to a port of the WRT61N switch. Not to the internet port. Every connection that enters in the ISP router goes to the Linksys, and then is NATed by it. I don't think those informations are very relevant but anyway here they are. That's a complex setup but it works well (needed to do that because I have cable connection, and the cable modem/router have very limited configuration).
The devices that use my two WiFi are :
2.4Ghz : My Razr i right now.
5Ghz : Two iPads, and the HTC 8X of my girlfriend.
I made some other tests, one the Razr i there is an option for switching on or off a kind of network frequency. So instead of both enabled, I enabled only the 2.4Ghz WiFi frequency and connected my phone to my 2.4Ghz WiFi. No problems detected. Stable connection. Right now I'm at work, and everything works well in 2.4Ghz. So there is clearly a problem with the 5Ghz frequency on my Razr i.
Anyway, during those tests, I discovered something very interesting. My battery life had a huge improvement with the desactivation of the 5Ghz WiFi frequency.
Thanks for the details - especially on the 2.4/5 GHz topic.
I am also at work right now, but will check it at home and keep you posted.
WPA2
I had the same problem, I think it was triggered everytime the phone went to "sleep". It was changing the security encryption that fixed it for me. I can't remember what i had on the router as default, and I'm not at home right now to check what I'm running, but I believe it's WPA2. After the change, I had no trouble whatsoever. Hope this helps, good luck!
EDIT: nevermind what i said, i just logged into my router and remembered it wasnt the encryption type settings, but rather the wifi standard used, it used to be 802.11 b+n+g, and now i got it sitting at 802.11 b+g, which equals to 2.4 GHz. Meaning the razr has apparently a problem with the 5 GHz spectrum..
I too have a RAZRi which is connected by wi-fi at home to a Fritz!Box 7390. I noticed that when the RAZRi went into sleep mode with wi-fi connected (keep wi-fi on setting) it would have lost any internet connection on waking, requiring a disconnection/reconnection to reset. More annoyingly there was also a loss of connection (IP address) at laptops also connected to the router by w-fi on both 2.4GHz and 5GHz connections, which needed a reboot of either the PC or the router to re-establish a connection. The router GUI would show them all as remaining connected.
By using the manual setting on the router to restrict 2.4GHz connections to b+g (not b+g+n), it looks so far as though both problems are avoided, and the RAZRi can be set to use either the available 2.4GHz or 5GHz (a+n) connection on the Fritz! successfully without problems. EDIT big problem is though that disabling "n" on 2.4GHz seems to cause wi-fi throughputs to crash by more than 50% on both frequencies (which for me negates the benefit of having VDSL) - they recover if I re-enable, but then the lockups start if the phone is connected. A hobsons choice.
Thanks guys.
i have a nokia 8 for a month now . im facing this problem on my wifi that only 2.4Ghz signal is displayed in my wifi list, it seems that wifi is not working properly because there are times that 5Ghz signal are displayed in my wifi list. its like sometimes it works sometimes not and take note that in using the same router with 2.4Ghz and 5Ghz. Also my other phone (Xperia XZ) is working will with both 5Ghz and 2Ghz.
Some routers simply do not work properly with particular phones. I saw such behaviour in the past. Check your Nokia with different router. b
sir i already try on different router, modem ang portable router but i get the same issue.
Try resetting the phone.
i tried it already. reset wifi and data, also factory reset but nothing happened. i already returned to the nokia store. thanks your response sir.
I had the same problem and I think I found the solution,
first of all I tried rebooting and resetting my Nokia 8 and I didn't fix it, updateing the phone did not fix it, returning the phone for a replacement I found that the new phone showed the 5ghz band then an error message appeared and no 5ghz wifi were shown anymore!
the problem is when you set up a new phone you will choose a country, this option will set not only the language but other settings as well among them the channels used by 5ghz wifi in your country! the router might be set to a different country using different channel!
solution: access your router settings and check your wifi 5ghz advanced settings choose a country matching your phone settings and restart your router.
if this didn't work try an android app called wifi analyzer and check channel settings for 5ghz after choosing your country it will show you which channel are open for 5ghz in your country,pick a channel and return to your router 5ghz wlan advanced settings and change the channel option from automatic to your the one from wifi analyzer and apply and restart your router!
hopefully this will work
Hello together,
I have a weird issue with my Xperia 10 (I3113 with unlocked Bootloader on 53.1.A.2.2).
At work we use Cisco ISE Sponsor Portal to provide WiFi guest access. I login using my credentials and everything works fine.
After a while I have to re-authenticate - this happens multiple times per day.
I noticed a similar issue with my WiFi at home. The phone is connected to the WiFi but has no internet access (same phenomenon as at work).
Has somebody experience a similar issue? Is this maybe related to the unlocked bootloader?
Greetings
I had wifi issues before i4193. It disconnects then reconnect itself automatically. I read some thread for xperia phones sine im unable to find any discussion specific for xperia 10. Luckily i found something saying that it underestimate the signals for dual band routers with 2.4 and 5ghz. My router at home is dual band but sharing the same ssid. I have it separated and now problem no longer exist. I can connect either to 2.4 or 5ghz signal without being disconnected. Hope this help.
Thanks for your reply.
I'm gonna try 2.4 GHz only and give feedback
Hi, when I woke up today I noticed my phone wasn't connected to my wifi anymore. I checked the router after restarting it, and restarting the phone, and all of my other devices are connected normally to both separated networks. I started looking through the wifi list, and all I could see is my 2.4ghz network. It is able to connect to that and it works normally. I checked wifi analyzer and I couldn't see any 5ghz networks when using it, only 2.4ghz. I read someone mentioning a snap in Lego style connector related to wifi, is this a possibility? I'm able to take apart the phone, and I need a battery anyway probably. Thanks, any help is greatly appreciated
