No internet through Wifi after 2.3.3 update

So I just updated my Desire HD with the new 2.3.3 update. I downloaded the update OTA using the wifi connection here at home. The download of the update and the installation itself went fine. When my phone rebooted after the update I was glad to see all my settings and apps were still there.
However, there is no connection to the internet anymore through wifi. It does connect to my wifi as I am able to use the Unified Remote app to control my computer. None of the apps however can use the wifi connection to connect to the internet any more.
I already deleted my wifi settings in my Desire HD and re-added them, but that didn't do anything. A simple reboot didn't solve my problem either. My mobile network connection works fine, although much slower than wifi used to be of course.
Does anyone know what I can do to hopefully get my internet connection working again?

This is a known problem...HTC gotta fix this with a new OTA ...

Btw, i can connect to my wifi, and also browse market and web with the standard browser..
Ps:Whit new 2.3.3 Ota..

Chefs have found the WiFi problem. It's not really a big problem. But HTC implemented a minimum WiFi signal strength, which is set high.
So if the signal isn't strong enough, the WiFi will be turned off.

Infact, here on my desk the signal is on the max, and i havent any problem..

I am getting problems too with wifi after update.
For some reason at home wifi is ok here i only reach internal network ...
Very Strange problem...

I doubt that's the problem. When I look in the Testing menu (using *#*#4636*#*#) and go to Wi-Fi Status it says the RSSI is between -51 and -76 which should definitely be strong enough I suppose.

You're correct
HTC has set the minimum WiFi strength to -88, which is imo too high :-/
That's why people will experience dropped wifi

So what is the solution?

Whoops. i don't know why I pressed the "Thank you"-button xD
For casual users: Nothing, wait until HTC releases a new update.
Chef gtg465x has provided a fix in "ROM Development"-section, but you need to root your phone and use CWM etc. If you're not familiar with these things, you better don't try to fix it.

I suppose that only helps when you have the problem of your phone dropping wifi signal when it is below -88? Then I don't think this will solve my problem, as my signal strength is ~-60 and the wifi connection itself works fine but just doesn't connect to the internet after the update.
EDIT:
My problem has been solved
It appears that my phone does not get the right information about the Default Gateway when using DHCP as it was set to 0.0.0.0. After setting the phone to use a static IP I could change the Default Gateway and solve the problem.
Now the question is, why doesn't my phone get the right Default Gateway from my server after updating the phone to 2.3.3?

iep thats my prob ...

Where can i find the signal strength of wifi in DHD ??
When i'm near my router, activating wifi on phone, it only tells "excellent" but there are no values.
Thanks for your advice

1. Open the Phone app
2. Enter *#*#4636#*#*
3. You should now be in the Testing menu
4. Click Wifi information
5. Click Wi-Fi Status
6. Look at the number behind RSSI

Wow, thats the reason, why i love this forum. Thank you very much. Your answer came blazing fast.
The value tells -57 to -60 (pressing on 'Refresh Stats') sitting directly near the antenna of my router
I can't evaluate, if these values are good or bad.
Would be nice to know, which range is good and which range might result in connection problems.
Thank you

Those are pretty good numbers I believe. I am usually getting between -52 and -70 when sitting in my room, which is about 6m away from my router (and through 2 walls). Apparently, anything lower than -88 is bad with the new 2.3.3 update as the phone loses wifi connection at that value.

Ahh i understand. So lower values are better than higher ones.
I heard, that it depends on the radio. I flashed 12.54.60.25U_26.09.04.11_M2 used with 2.3.3 (MDJs VivoSense 2.1) and it works very good. (no wifi drops at all).
GPS is fast as well. After some seconds i get about 8-10 satellites.

This is pretty annoying problem, why did HTC changed it when it worked good and making it worse?

try wifi fixer from market.its pretty good.write here pls if u have ay probl.

wifi issues on N4 possible fix?

for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?

still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength

I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

Public wifi and my work wifi working perfect with n4. So it definitely my routers wddrt firmware issues with n4... still gottta figure it
Sent from my TC970 (Wi-Fi) using xda app-developers app

My n4 will not connect to any of the WPA2 AP's around here.

I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.

So this n4 is picky about. Certain WiFi networks.configs
Sent from my Nexus 4 using xda premium

Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.

Set lease time for as long as possible, it normally this is 2 weeks..

can you test to flash back CWM recovery and test again the wifi ?

Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.

I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

will android switch to a better wifi if available?

Heyho, i currently have access to my wifi as well as to my neighbors network as my wifi gets weak while i am in the garden. I feel like android isnt awitching to my neighbors wifi automatically. Only when my wifi is completely gone, android will look for a new one.
I thought about making a task with tasker which looks for another wifi as soon as the current wifi strength goes below 25%.
Or is/should android do that aleady on its own?
Thanks

In wifi -> Advanced settings there's an option to avoid poor connection. I have no idea what it actually does, but give it a try.

I did the test with my router, which supports 2 frequencies.
Assuming both networks are saved in the phone, it connect automatically to the one with better signal or look for an alternative if signal is lost.

Thats what I mean, it will connect to the other WiFi if the connection is lost. But if the connection is crippled (bad) enough to not handle a music stream, but still "availabe" it will not switch to the other WiFi eventhough that other WiFi has 100% signal strength ?
I activated the "use wlan only if good strength available".. lets see how this works

I have multiple APs in my house and the only way I've ever got it to switch is by toggling wifi off and on (or loosing the first signal completely). This is an Android issue IINM, my GS2 and my N4 both have this issue.

I tried the "do not use weak WiFi".. didnt work.

It has never worked for me either. Didn't work on my GSM GNex or with the N4.

I think it's how most WiFi clients work, otherwise if you were in the middle of 2 equal signals, it would spend more time disconnecting and reconnecting creating a DOS attack on the 2 AP's and leaving you with no data.
As for 2 home wireless routers, use the same SSID and authentication settings for both, and put one on channel 1 and the other on channel 11.
Make one a AP only (no router, no firewall, no dhcp server) and connect it to a client wired port on the first one. You can roam between them like people in large offices do.

or I try to make a tasker profile
if wifi strenght below 20% and another wifi is available with more than 30%, connect to that one.. then wait 5 minutes ?

[Q] S4 GT-I19505 wifi issue. "your Internet connection is unstable"

I have recently upgraded my Samsung S4 to 4.4.2. I have discovered that my WiFi performance has reduced and frequently I am receiving message " your internet connection is unstable". I can observe that down arrow on wifi doesn't blink at that time. While on the same time other devices like Iphone, ipad, Laptop on the same WiFi are working fine. Can anyone help me in this regard.

I think it's because too many devices are connected to the wifi router. I get this message as well when connected to uni's student wifi

Errr, no.
I have MAC filtering on my router (so no unnoticed intruders), and it happened when no more than 2 devices (SGS2 and SGS4) were connected...
Do I need to mention that SGS2 does NOT loose WiFi?

In your advanced settings for wifi un check auto network switch. i was experiencing the same issues and this has resolved it. Auto network switch monitors the quality of your wifi and if there are any issues on the wifi it will switch back to mobile internet. Can be a real pain.

WiFi unstable

WiFi is very unstable when you aren't next to the access point. It keeps switching from WiFi to data connection.
Furthermore, when gripping the phone from the upside without a cover (near the camera), the WiFi connection will not work anymore.
Someone is experiencing this problem?

same to me

WiFi works normal here... No deathgrip

Maybe you can try enabling Aggressive WLAN to Cellular handover at developer settings under the networking tab to fix your issue

Well, the problem in my case was that I have two access points with the same name at the two sides of the house, and from my room the second AP has a better signal, but it had some trouble and it wasn't working, so the phone wifi was switching from the first to the second continually.
However if you hold the phone from the upside, there is a very strong loss of signal. A workaround is to use a case.
I can say that wifi antennas of this phone are not that good, like the iPhone 7.
My previously Xiaomi phone had a better wifi signal on very distant access point.

I've changed ssid of 5Ghz wifi (now is different from 2.4) and wifi don't disconnect random anymore.

Yes, the same SSID on different AP / technologies makes only troubles.
Never use the same name for 2,4Ghz and 5Ghz. Unfortunately many providers have the routers that are configured this way.

I've configured my router with same ssid to use band steering (i can't post link: search "band steering avm" from a search engine)
That technology do exactly the trick: switching from frequency bands, but even disabling it Mi A1 doesn't manage WiFi correctly and don't suppose to do that!

Hi Guys
Is there a solution for unstable wifi connections.
thank you
