[Q] HTC Desire WiFi problem after Froyo upgrade

Dear Users.
On monday i have upgraded my phone to Android 2.2.
After update, my phone is unable to connect to secure WiFi routers (even my own, where i got update!).
I have linksys WRT300N.
Is there anyone who knows something about that problem in HTC software?
TechSupport told me that i should twice clear settings to factory settings (without SD card in phone). I did that few times, nothing.
Thanks

Please explain what happens when you try to connect. Is it impossible to optain IP, if so then it is a knowned problem since before Eclair :-(

I'm stuck on "obtaining IP adres", it doesnt show on unsecure routers.

I'm in the same swamp as Mystenes, can connect on various other routers, but can't obtain an ip from my linksys wrt300n. Setting a static ip solved the issue for me, not ideal but can connect at least
Hope it helps (if you need help setting static ip I can help)

I also have a 300n, I used the dhcp reservation to assign a designated up to the desires MAC address, wouldnt connect otherwise. Works fine.

i can connect to a linksys with dd-wrt but not to a belkin and various others...

[Q] DHD keeps refreshing IP until router crash

Hello!
So it all started when I updated my MIUI rom. When I connected my phone to the WIFI my router crashes after a while.
So apprently my phone refreshes the IP adress until it crashes or something. Anyone had similar problem? Appreciate all help!
Ive know this cause when I loggon my netgear and check mac filtering you can see my router giving out like 30 IP adresses only to my phone.
Ive now switched rom to Cyanogenmod 10.1 , but the problem still occurs.
Regards Meyahx!

go into advance wifi settings and give a fixed IP to the phone
if your router is e.g. 192.168.2.1 , give a 192.168.2.x to your phone, so it doesnt ask different IP from the DHCP server (that x must be a number)

[TIP] Wifi connected but no internet connection!

At some points in your life, one of your Android devices connect to a wifi router, but can't connect to the internet. However, your computer, laptop or iPad will connect to that same wifi and use the internet just fine. I've looked everywhere on the internet for solutions, some of them are:
+ Turn off and on both modem and wifi router
+ Factory reset wifi router
+ Battery pull your phone, wait 30s and put it back
+ Reflash stock or custom ROM
+ Change DHCP IP setting to Static
+ Disable security (WEP, WPA) on wifi router
+ Check DNS server, gateway IP address for correctness
Fortunately, I stumbled upon this old thread last night -> http://forum.xda-developers.com/showthread.php?t=1371794
It helped fix the internet connection temporarily, turning off and on wifi on phone caused the issue to repeat.
In summary, he found out the correct MAC address for gateway was mismatched with the one on his phone. Even though the gateway IP address is correct (example: default gateway IP 192.168.1.1)
Upon further investigations, I found out my Wifi ROUTER has the same IP address with my MODEM (192.168.1.1) This IP conflict causes the phone to recognized the WIFI ROUTER's MAC address as the gateway's MAC address. This problem mostly occurs on Android phone, not computer (I'm no tech savvy so I have no idea why)
Simple fix: Go to wifi router setting page, change the IP address on wifi router to different number (other than default 192.168.1.1), and the problem should be fixed.
Please help spread the words to fellow Android lovers, I'm sure a lot of us have struggled with this problem :laugh:

I'm one guy who is desperately looking for a solution to this.
Unfortunately the solution you gave didn't work.

Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
any idea?

Turn off wifi optimization on some android phones help.

Had the same problem for several months. Changed my router and everything became prefect.

2 years after the last reply I am having the same problem. My wife and kids all have internet access on their phones, tablets, desktop and laptops all from the same modem router yet I am unable to use the internet on my Galaxy S2 mobile phone even though my phone says connected to Wi-Fi Network Netgear 06.
The Mac address solution provided isn't applicable to my situation as my Mac address on my mobile is different to my modem router Mac address.
Any other solution?

[Q] Unable to Connect to WiFi

Here is a head scratcher...
When changing the IP subnet from 192.168.1.x to 192.168.2.x (or any thing else for that matter) the HTC One M8 will not connect to the WiFi. It will only connect when the subnet is 192.168.1.x. All the other devices - even an iPhone - work without issue when moving them to the new subnet. Everything on my LAN uses a static IP address. I assign them all myself and write down what devices use what address.
Does anybody know how to fix this? The phone is 100% factory and it is not mine, so rooting is out of the question.

WiFi MAC address 02:00:00:00:00

My S4 mini (GT-9192) running cm13 cannot connect to the WiFi network and the mac address shows 02:00:00:00:00:00 rather that the unique address it is supposed to have. My question is how can I fix this? any help will be appreciated.
EDIT: a soft reboot fixes the problem temporarily. If there is any permanent solutions,please let me know
