Wifi will not activate

After flashing with a new ROM etc..
When I go into communications, and tap on wifi.....it turns on for a sec and then turns back off. Any suggestions?
Here is what I have done so far.....
Started with: Radio v. 1.39.00, ROM V. 2.13.656.2, Bootloader 1.2
Went to bootloader 2.40(via Hard-SPL-MF.exe), Scrosler's Titan ROM 3.26 w/touchflow. and then Radio 3.42.30.
Thank you in advance for any suggestions or solutions.

Try the hardware switch on the side of the unit. The software switch was never able to work under most ROMs that I have ever used.

I toggled that (WiFi switch), and it does the same thing for me.

Should I try another ROM or radio version? I don't want to do a bunch of flashing.......anyone know a good firmware version (and radio v.) with everything working and ready to go in terms of functionality? I don't mind putting all the carrier info in etc, just want all the radios to work afterwards (wifi, eV(cellular data), cell, bluetooth, IR)

Never heard of the problem. I say reflash because something happened.

Changed the battery power option under wireless to best performance.....everything works now

That's odd behavior. Post if it happens again.

When I use the ppckitchen my wifi refueses to work. I'm actually about to reflash it right now to DCD to see if it fixes it

Same Problem Here
The Switch seems to be malfunctioning...WHen I turn it off, it turns on the software for a second, then shuts off. WHen I turn it in the same thing happens. Really weird.
THis happened BOTH TIMES i reloaded the ROM.

im using the Kaiser Comm Manager(10 Buttons), and on it it always appears that the wifi is turned off, but functions fine with the switch

i have used dcd 3.2.6 and 4.1.2
and im currently running ryan 2.0 i think wm6.1

DO you see a MAC address in the WLAN advanced settings?
If not, you just need to write a new MAC address and your WIFI will work, or so I have heard.
so... how do we enter in a MAC address if it is missing?
Anyone?

guys
theres no fix take it to sprint and they will replace it happen to me twice

Mobile Reception Inconsistant after hard flash!!!

After doing a Hard Flash for the first time from 1.43 to 148 and rebooting my HD2. Within several minutes my reception speed would change from 3G to GPRS and back again while on the go, this has never happen before and was wondering is there a way to have consistent 3G speed/reception or was there a fault during my flash?
Any suggestions or help would most helpful.

Did you flash with SSPL / Gold card or with the HDSPL in-tacked?

EITHER WAY:
Press Phone Key>Options>GSM/UMTS Services:
Here select Band....then, "Get Settings"
The first tab should say GSM. Drop down menu option you want is WCDMA. This will force 3G all the time. However I don't recommend this setting as this will consume more battery.
Leaving it in 2G saves more battery and voice quality doesn't change....

hi,
maybe you flashed the radio part of the rom also, when you flash from 1.43 to 1.48?. im not sure, but you should check out this htc update, and try it. its a replacement for the radio portion of your rom only, and maybe fixing your problems. my singnal strengh has stoped to swing between full and no bars, and i have full bars most of the time, with this update.
regards mad.

Stock Roms include the Radio so if there was a change between one stock and the other then a change will occur...
There is nothing wrong with the radio band switching automatically though so unless you have bad reception, everything should be fine.

Thanks

Try if switching to 2G networks only in the settings solves your problem, this did the trick for me.
I only switch it off for fast 3G downloading, solves the missed call issues for me too.

With all tho respect i havnt got an option USE ONLY 2G Networks. I have Downlaoded widget APN ON/OFF. It has switched it off Thanks

For me when I was in Poland radio 2.14 or 2.15 solved the problem.
I am now using 2.14, I can see that you are using 2.12 I would change that to be honest and install other radio, just experiment a little and see which one is best for you

True but i'm unsure if its a network related problem or android because i flashed so many roms with different radio's always experiencing the same data conection drop problem when 3G is on.
So i just flashed back to the stock nexus build to stay.
I wish i could use the full potential of my device too...
(The menu to switch on only 2G network is only available on stock android rom, not on sense roms etc as they use their own menu styles)

Im now definitely sure that its not a hardware related problem as i tried 4 different EU HD2's and they all had the same problem after flashing android.
Now it's only to find out if it's a radio - android compatibility problem or just a flaw in android itself.

Ok,, now again for the 10th time , i started over from task29 , up to installing radio 2.15.50.14,, then boyppc v25 rom,,, and i guess this worked for me, i still have the connection dropping but less often than it used to be. it happens maybe once a day.
isn't there a developer who can help us find out what is the problem and develop a solution for us???

[Q] WiFi issues on almost all ROMs - MB525 red lens

Hi All,
Since I got my DEFY I have WiFi problems. This issue only exists when WiFI has WPA/WPA2 PSK authorisation.
It is going like this: I connect over the wifi. Then connection works fine, I am able to browse www, check the emails etc, and after few seconds, minutes the connection stops working but still exist. I try to reconnect several times. Defy shows that is connected but nothing works fine. Internet apps or Market gives a message like the time is up, connection lost. I have to forget the conection in settings or reset device to get it working properly, but not for long.
And the thing is that there is only ONE ROM that works fine with WiFi on my DEFY. This is Cyanogenmod-7.1.0-RC1. Other ROMs have same issues. Doesn't mater if it is Cyanogen mod 7.1 stable or any MIUI or MS2Ginger. I tried almost all roms but nothing helped. So I had to go back to CM7.1.0-RC1.
Do you know what should I do to make WiFi working fine on other roms?
greetings,
Gregory
p.s.
Please, just don't tell me that I should change authorisation on WiFi router. This is not a solution for me, because I use WiFi in a lot different places.

Same problem
Hi,
I have the same problem with my Defy since a few months, no solutions!

I have the *EXACT* same issue. Was about to roll back to stock and send it in for repair, glad I found your post! I'll install the ROM you suggested and keep hoping this gets fixed

just fixed my wifi issue for the second time. If there are to many remembered networks no more wifi. You can turn it on but it cant find any. delete all remembered networks and back on line. that is the only conectivity problem I have ever had after months of cm7

I think that's a different problem than we're having. It is finding the network just fine (and connecting) in our case. It's just that internet connectivity refuses to work after a few minutes, forcing us to disconnect-reconnect to get it working again
@OP: Thanks a lot! The ROM you mentioned does indeed not have this problem. It's not as stable as some of the more recent roms though, think I'll still be forced to revert to stock

i had exactly that problem with my first defy, no solution man, i send it to warranty and they give me other

maybe changing the regulatory domain channels from 11 to 14 could help. this option is hidden by default, you have to enable it: change the value of 'ro.debuggable' from 0 to 1 in /system/bootmenu/config/default.prop, save and reboot. after that, the regulatory domain setting will be shown in settings/wireless/wifi/advanced. simply change it to 14 channels.

Thank you for the suggestion! Just tried this, didn't resolve the issue sadly
I'm looking into rolling back to a stock Froyo rom but the information is scattered all over the place, I'm having a hard time figuring out if it's possible, and if so, how ;/

Anyone have any more ideas? ;/

OK, maybe I just passed the signpost but... do you still have the problem if you set your "select network" setting to 3G only?
I ask because (and it may be different on my phone as I am USA, stock ROM with wifi calling) if you go into the INFO menu > phone information > set preferred network type, mine toggles between three radio preferences: "GSM only" (when wifi is active), "GSM auto (prl)" and -- if I set for 3G Only, "WCDMA only".
I have noticed that when "select network" setting is at automatic (or 2G only) it often has trouble transitioning from cell to wifi. And, when wifi is an issue, I find that "GSM auto (prl)" has been selected (which on my USA phone prevents wifi connection). However, it seems to have no issue whatsoever transitioning from "WCDMA only" (3G only) to "GSM only", which on my phone then allows wifi connection. Again, this is a wifi calling phone so may be different.

Yep, same here BUT ! I get root browser, found my build.prop and change wifi chanells first time for 14 and it didnt help so i try other and my wifi works in 100% with 13 chanells. Try it

This is a widely know problem, many people are affected more or less. I'm also having nerve-blowing times with wifi sucking all over... Stock Froyo (and now Cyanogen 7.2) seems to be a bit more stable, sometimes everything is fine for a few hours, all downloads go lightning fast - and then suddenly things are screwed up. I tried a lot of MIUI releases as I like it most. MIUI seemed the most problematic so far. I don't know what is the cause, new stock Motorola Gingerbread ROM versions also have this issue (except one I think - look it up in the forum).
Agree, bothering with the router is not a solution. My Nokia E51, my EeePC, my girlfriend's Omnia and Lifebook - all work perfectly with all the four routers we use frequently. Not a single glitch - everything is stable and nice, except Defy.
I don't think is a hardware problem with certain devices, it seems more to do with the way Defy handles wireless connections.
Anyway, it's frustrating but CM7.2 and CEE Froyo gives a bit better experience than others.

No, problem still persists. Sometimes it works flawlessly for hours. Then... suddenly screwed :S In some cases a "switch wifi on/off" workout can help but not always.

Which Froyo version do you use? A few times this wifi-bug occured also under Froyo. I'm thinking about going back myself, as Froyo is the only acceptable release to record hiccups-free videos

ICS issue with modem

Hello,
I installed Sam's ICS RC2 for SGS and it's amazing, however, wifi works but I can't connect to network, the phone fails to connect. I have tried flashing other modem (XXJVT i reckon) without any result.
Any ideas?
Thanks.

I do not see how a new modem will affect WiFi. AFAIK, the wifi stuff is built into the kernel.
Does this happen for any wifi network? Have you tried connecting to some other network?
If nothing connects, you might be looking at a factory reset and data wipe

Data enabled setting is for data transfer over GPRS/EDGE/3G networks, not related to WiFi at all!

I agree. I may have misunderstood the question. The OP said that wifi works and he can't connect to network. I understood that to be the mobile network seeing that he is talking about modems.
Wifi has nothing to do with modems.

Aah! Now that I read it again... I think I understand what you understood. The OP is a bit ambiguous in that case

Perhaps it is an issue with the pin unlocking code. Can you put the sim in another phone, remove the SIM lock pin, then try it back in the Galaxy. It might narrow down the issue for the devs.

I have try ics on miui galnet! It uses JV5 as modem! My signal is the best! I have try more modem but with ics signal is very good! I do not test consume! If you want, you can install other modem! I suggest JPG modem! It works fine and less consume of battery!
My operator is H3g italy!
You can find you modem only trying it!
You measure performance signal (3g, 2g, wi-fi, gps) through apps market about signal and consume with time elapsed.

i'm using the zsjpg modem with ICS (for cyanogen kernels). very good modem.
edit: if the cwm installation doesn't work, try the updated version (like the new thunderbolt scripts).
edit2: it seems like the zip doesn't work anymore for new ICS builds :/
