Wifi keeping my HOX awake

After trying variuos ROMs (2 variants of Sense ROMs and this CM11 one) I am still unable to avoid a serious and quite known problem: when connected to Wifi my battery drains fast. After installing BBS I noticed that the phone doesn't go into deep sleep. Something is keeping it awake. The strange thing about this issue is that just a few of the HOX's seem to be affected. I'm curious what do you guys think about it and maybe you have some advices? I really love my HOX, but this is shortening my battery life too much. I'd rather try everything before selling the device. Thank you in advance.

I attached a BBS log. With current settings (location reporting and stuff) if I disable Wifi everything is ok.

P.S. Also tried relocking, reflashing firmware, unlocking then flashing custom ROM but still no luck...

Hi, I had this problem too in history with all my phones. Problem was not on phone, but in WiFi router's settings. Do you have problem only on certail WiFi network or on all WiFi networks? Do you have this problem too when you are not near WiFi (for example in forest...)?

I'm having this problem with my home & office router. Didn't have the chance to test with other routers. I keep wifi on at all times but once the connection to the wifi network is closed, problem is gone. It must be in the software somewhere because my router is way older than the problem. Maybe with the update to JB HTC broke compat with some routers or their settings? Who knows... My wife has the HTC Desire 500 and she doesn't have this issue.

[Q] Wifi doesn't work

Hi there,
Today I recognized that my wifi doesn't work. I can switch it on an there is also a massage that there is a wifi network available in the notification center. But if i open settings/wifi the phone writes no wifi networkes available.
My Z1c is rooted (KK .757) and locked bootloader.
Has anybody a idea how I can solve this problem?

This happens to me sometimes, after a restart works for me. May be next update may solve this problem

I've already restarted 3 times but doesn't help.

You can try: 1. restart your router
and 2. delete the settings for your network in your Z1C and make a new registration.
Is the problem solved?
I think no.1 will solve the problem. What a router do you? Many routers can do a automatic restart after flashing DD-WRT or Open WRT. These firmwares are available for the most routers.
greetings

What do you mean with 2.??
I've already tried to restart my router. But I'm pretty sure that the problem isn't the router because I can connect with other devices to the router.

go to settings - WLan and tap long time on your network and delete it.
It does not matter, that other devices can connect to your router.
I had the same problem with a TP-Link router after few days running. A restart helps only.

Delete the network doesn't help too.

Usually I find also the wifi networks of my neighbours. But now I don't find any wifi network.

For sure you have problem with your router since low cost routers is nothing than an s***t ! I had the same trouble with an low cost router until I come back with an good Dlink DSL2740B router 5 years ago, everything working flawlesly constantly ~5 years, no wifi isues! My sugestion to you is to buy an good home router! I have plan to bye this one http://www.dlink.com/us/en/home-solutions/connect/routers/dir-880l-ac1900-wifi-router which will work for sure perfectly next 5 years (probably more)!

I've solved the problem already. The problem wasn't the router.
I had to wipe DATA and then my WIFI worked again.
Then I tried to restore a backup what I've made befor but then wifi doesn't work any more.
So there was something buggy with my DATA..

Nexus 5X can't find any wifi network

So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.

I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.

my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:

Wifi problem

Hello there, I have been having problems with the wifi of my redmi note 8 pro, everything should be working fine, the signal is strong (I'm next to my router) but when I send whatsapp messages the took many seconds to be sent and when I try speedtest, most of the times it asks me to check my wifi conection anyone with this problem or any possible solution?
BTW the battery management is MIUI default, no battery saver enabled at the moment.
My internet conection is 20mbs, the network is not saturated as in my computer I receive the 20mbs without a problem the upload speed of 2mbs is also working fine.
UPDATE: After trying everything to solve the issue, the problem was in my router config as it was related to a reserved IP Address that caused conflict with my phone DHCP.

having the same problem, what did you do in your router exactly..

How was it exactly fixed? Thank you

It seems he had an ip collision problem : 2 devices with same ip address on his local network.

I have the same problem but a don't have IP conflict into my network. What do i have to do to solve this problem?

If you find out solution for this, post it... As I have same issue and Xiaomi support is not helping me a bit.

Are you experiencing the wifi/Bluetooth bug?

My Redmi Note 8 Pro WiFi keeps on disconnecting. Running on Stock MIUI 12.0.5, Non rooted.

Connectivity issues

Hello,
I have the global version of the mi9SE and experiencing very annoying issues when trying to access certain websites OVER MOBILE NETWORK (WIFI works) which returns errors as per attached screen shots, reporting certain sites (banking particulary) as can't be found or offline.
I temporarily managed to fix the issue by changing APN settings from IPV6 to IPV4 as per a suggestion on the forum of my French network carrier. Unfortunately with the update to android 10 and MIUI 11 erased these settings and now 4g or 3g for that matter simply fails to connect over IPV4 setting after update so I’m back to square one which is immensly irritating.
I can’t work out if this is a carrier issue or a software bug. I’ve tried the following :
- Changing Sim to another phone. No problems there.
- Changing browser. Both chrome and edge are the same as well as the native browser.
- Contacting bank who tell me issue not unheard of but have no solution.
- Contacting my carrier who claim not to have an answer.
I haven’t tried another sim in the handset.
Help would be much appreciated.

Hi
I also use French carrier, bouygues, using android 10 miuimix, just tried ing website and it works fine through 4g.
Have you tried a different ROM? You should have a menu to erase connectivity data in settings may be it could help

Hi thanks for your reply. Vey strange, I too am on Bouygues network and ING website doesn't work for me.
However I must point out that it is the secure part of the website that doesn't work so logging into the "espace client" part of the account, the home page DOES work. Same for you or not ?
I don't understand how it can only be me experiencing this issue which I've had for months now despite doing a factory reset, formatting etc. I'm using the stock global rom OTA from Xiaomi. I surely shoudln't have to flash another rom to get a working phone. I take it Miuimix is a ROM you're using on the Mi9SE ? Just how stable and secure is it ?
tks

MY WIFI hotspot won't work either. It connects to the network but refuses to connect to the internet. No such problem when placing the same sim into another phone and setting up the same hotspot. Could this be a problem with my device hardware I wonder ? I haven't done anything in particular...but these issues weren't there when I first bought the device.

For Hotspot I guess it's related to Android 10 update...
Just tried the secure part of the ing website and indeed it doesn't work for me neither on 4g. But Hotspot works fine.

Great thanks so much for trying at least I know it isn't just and so can conclude an issue with MIUI and the phone. Strange how adjusting VPN settings to IPV4 used to work but now doesn't. I fear the issue is embedded into the OS and I'll probably never find a solution . Wouldn't be so bothered if this was the only site but it's not. I first thought it was just a problem with the websites, then realized it wasn't when the same sites worked over WIFI.
As for the WIFI hotspot issue, still no solution to this problem. The same sim is fine in my Motorola and connects to the internet perfectly over 5ghz band. If I try 5ghz band on the SE, windows simply reports "unable to connect to the network" and over the 2.4ghz the device network will connect but reports "no internet".
It doesn't sound as If the two issues are related from what you say. Is it possible it's the windows firewall blocking the Xiaomi but not the motorola ?
