[Q] Android 2.3.3 wifi compatability problems in custom roms

hi guys, go easy on me its my first post
love the website the guides have helped me to successfully downgrade, s-off and flash custom roms to my dhd
I searched for the answer to this question but couldnt find anything. Is there any plan for custom rom developers to fix the 2.3.3 rom wifi compatability problems with speedtouch modems, as this is the only reason i cant use 2.3.3 based roms? (a lot of people have this problem with the stock rom but it is also in leedroids new one, android rev. etc) Would like to ask this in the android dev section but i need 10 posts for that.
Thanks for the help you lot have already given me, and i love the video!

Hi, welcome and congrats on your first post.
What specifically is the problem with the wifi? Is it specific to a type of authorisation (WEP, WPA/2) issue or something else?

thanks
this is a link to a detailed description of this exact problem: http://forum.xda-developers.com/archive/index.php/t-1063103.html
i really dont expect anyone to go through the hassle of reading this, so summarized it says that ever since the gingerbread 2.3.3 update the phone is capable of connecting to all modems, but cannot transfer data on certain ones (such as the speedtouch modems)
I found a good post on this in a german forum a couple of weeks ago but i cant find it now, (i'll keep looking) but it said the problem was that some modems transmit with n and some with b or something like that. and that the only answer was to wait (ages) for a stock rom update (2.3.4?) as 2.3.3 isn't compatible with these types of modems
i would have expected this had been solved in the custom roms though

this is a qoute from the link below
"It turns out the Be Box router which Be supplied, which is a THOMSON ST585v6, is not compatible but also other versions of THOMSON routers as well."

Ok, just read through that thread. What model of Speedtouch router are you using?
One workaround is to use a static IP. Have you tried this? I can help you set this up if required.
HTC seem to blame this issue on Google, as an Android issue. Not sure about that as any ROM that uses Gingerbread would exhibit the same problem, which isn't the case.

modem is a Thompson Speedtouch ST585 v6
Thanks but i have already tried and the modem only works with dynamic IPs (tried to solve it with a static IP for ages with my dad but it didnt work xD)
This qoute from dioky on page 4 of the link below states (i'm pretty certain) the problem: (i clicked the thanks button for this answer)
"Hi there,
I have the same WiFi problems as all of you.
Furthermore I can confirm that changing ROM (ARHD or Leedroid) won't help, if you stay with Gingerbread versions, that is.
I found out that:
* Data won't flow (although connected fine) to SpeedTouch WiFi access point (b/g).
* Data won't flow (although connected fine) through D-Link DAP1360 .
* BUT: does flow (and connected fine off course) through Belkin G Plus MIMO access point (g)!
I have rechecked it by reflashing back to ARHD 3.7 returning to ARHD 5.1.7 and ARHD 5.1.4 and LeeDroiD 3.0.3.
Which in all, makes me conclude that there definitely is something on the software side concerning compatibility!
For now, I will return to ARHD 3.7 Android 2.2.1 until solution is found.
Regards,"

Does anybody know if the Rom devs.plan to solve this (or even know about this problem)?

any ideas peeps?? this is a major problem for me

You want to try giving a static IP another shot?

i'm pretty sure it wont work as i tried to solve the prob like this but whatever i did i couldnt get it to work. but i'll give it another shot. another idea would maybe be updating the modem drivers if there is such a thing?

What is your routers current firmware version? And is that a branded router?

i really have no idea. i'm a total noob with routers
can you tell me an easy way how i could find out?

Sure, are you using your PC to access the web at the minute?
If you install TeamViewer I could show you.

?????? What is that ?

Its a piece of software that will allow me to remotely control a computer.

I can confirm that I have this problem with 2.3.3 and my Thomson/SpeedTouch 585v6 (FW 6.1.4.3) too.
It seems to connect WiFi fine, even assigns an IP but nothing actually works.

Solution for Wifi problem 2.3.3
Hello!
I have the same problem on my DHD with 2.3.3
Before there is an permanent fix for this You could manually configure the IP adress in the phones Wifi and it works great.
You can not use the DHCP in the phone.

I should have mentioned that I actually have a HTC Desire (not HD). But the ROM is a 2.3.3. It actually assigns the IP via DHCP just fine.
I have already tried manually assigning the IP address (and other fields) but still no luck.
There are those who can connect with a manual IP and a few, even after assigning it manually, still can not connect.

i tried using a static IP but it doesnt work..tried for days now
sounds like i am one of the few it doesnt work for after assigning manually...
i am a total noob but i was wondering if it would be possible for a custom rom dev to take the wifi drivers from froyo and use them in a gingerbread based rom??

UPDATE
I called up my ISP requesting a newer firmware for the 585v6 router (although I know it is no longer supported). Anyway, without any hassle at all, they gave me the newer: TG585 v7 router with firmware 8.2.23.0 (pre-installed).
This connects without any problems to my 2.3.3 ROM (RCMix 2.0).

Router crashing with new Jelly Time rom

Hey guys,
I tried searching and could not find a similar problem.
Since getting the new rom I have noticed that my wireless router has been experiencing connection issues. all my devices show connectivity but i dont have access to the net. Anyways i decided to have a look and the android is creating multiple Ip entries on the router with the same mac address and everytime I turn the wifi off on my phone the problem does not occur.
Any ideas?
Thanks

Have you tried going into development settings and turning of Android Debugging or ADB over network? Just a suggestion, not sure if it will work.

nah cant be that, I had them turned off already.
Thanks for replying anyway. I searched google and its a pretty common problem with no concrete solution, might need to flash the rom again.

Why don't you try binding the MAC Address to a static IP so it's no longer able to create multiple entries on the DHCP Table?

tjturko13 - have you tested to use another standard 802.11 Modus - instead "n"? Just switch it at your phone or router.
What router do you have? Can you update the firmware? ^^

i dont think my router allows this, the only option I have is to specify if I want to allow mac filtering.

Have checked out my last post about the wlan-standard?
I found also another thread about a member with wifi problems after updating his rom. He didnt flash the new boot.img - but dont know if it was the solution.

its a isp provided cablel router that does not let me mess around with FW but i have checked and it seems to have the latest FW

where do i get the boot.img file from?

Did you get your new rom over the air? (Stock rom)
Or did you flash a custom rom?
You have to give us more software informations about your rom. Is your device s-on or s-off?
Stock rom you need the right RUU exe file. Just doubleclick - yes yes yes
Custom rom you need to download the custom boot.img.

There is an update available. I saw another post of an user with wifi-problems. He flashed the update and the problems were solved.
I've also noticed, that the wifi might have some problems with some channels as you can see here:
Broken:
bluetooth - works in beta 7. Broken in beta 8 +
Working:
Wifi Tethering
camera - not perfect still buggy
Mic
accelerometer
audio
bluetooth
wifi - may not support some channels

I'm sorry for you.
- You could even try to change the wifi-channel to 1, 4 or 6 and disable wifi-security in the second attempt for test only.
- Try also to set a static ip in your phone (for your wlan).
- If you are bored you can reset the whole router to its factory defaults and leave all standard. Just enable wlan (and the isp connection) - but dont change the default ssid, wlan-security or channel etc.
Otherwise I have no more ideas.
With google you can find dozens of users crashing their routers with android or ios phones . Good luck dude!

Ive had this problem to since switching to 'randomblame's kernel based ROMS (jellytime CM, jellytime aokp and jellytime by PACMAN - Paranoid, CM and AOKP).
Apparently it is a kernel issue and the only thing you can do is some of the things above or here
I was here hoping there might be a fix... I tried static IP, changing the router channel, WIFI never sleep etc etc etc.
The only workaround I found so far was to turn off wifi when Im done, it only seems to break when the phone is inactive for 5 minutes +.

Exact same problem here. It took some time before I figured out that my phone was overwriting my gateway's MAC address, but I finally saw that message from another machine in my network:
Code:
arp info overwritten for 192.168.1.254 by 91:31:58:5d:e8:34
1.254 being my gateway's IP. I also tried giving my phone a static DHCP entry but it just didn't change anything. Any useful sysctl maybe ?

FWIW, it seems I "fixed" that issue by making my routers MAC address association permanent on my (manageable) switch. That obviously don't fix the real problem, but does not shut down the router's NIC. FYI, on a GNU/Linux machine, this is done with the arp command, i.e.:
Code:
# arp -s 192.168.1.254 00:ca:fe:ba:be:00
192.168.1.254 being your router's IP

[Q] Wifi Issue With Mimicry

Installed Mimicry 1.50 and am having issues connecting to wifi. I read the developer's post (http://forum.xda-developers.com/showthread.php?t=1714187) and tried all the methods mentioned there to fix this issue, but no luck. This included flashing an updated RIL (which was great for improving my reception), flashing the .19 radio, reinstalling the ROM without updating the .19 radio and wifi calling option, installing wifix, and getting a new sim card.
My G2 can detect wifi networks but will not connect to them. Possibly related, it also detects, but not connect, to bluetooth devices.
Is there anything else I can try? I really like this ROM but this wifi issue is driving me crazy.
Thanks.

I just flashed Mimicry 1.50 and I'm having the exact same issue. Quite odd.
---------- Post added at 12:33 PM ---------- Previous post was at 12:16 PM ----------
Oh wait ... nevermind ... I was stupid. I turned my wifi router off and on and everything started working fine.

Doesn't appear that there are other solutions to my problem. I may revert back to the stock rom, re-root, and reinstall Mimicry as a last resort.

Thought I would update with my solution. Turns out my router was set to broadcast in N only. I changed it to broadcast in both G and N and I was able to connect to wifi. Hope this helps others with wifi issues.

Wifi stuck in obtaining ip address

Hi..
Just installed Omega 7.4 ROM, but happened with wifi problem which getting stuck in obtaining ip address..
Tried WanamLite also the same.. Probably it's becaused of JellyBean 4.1.2 caused this problem.
Downgrading to official ROM, the problem dissapeared..
Anyone suffering the same things ?

You're not alone. There is a thread on the same issue here:
http://forum.xda-developers.com/showthread.php?t=2044249
Unfortunately so far there isn't a solution and the only commonality at this point seems to be 4.1.2.

Ok thanks for your reply..
I will revert to stock ROM 4.1.1 as 4.1.2 has some bugs.

Sometimes my pc gets sick at obtaining ip address. A quick reboot of router solved it. No harm trying.

this is not related router problem.. after flash back to stock rom, wifi can connect successfully.. it's the kind of 4.1.2 bugs. nobody can solve this ?

Hi,
if you want, you can try a Marshmallow ROM.
Kind regards

I have the same issue. Suddenly, my GN2 could not connect to any Wifi router (secure or open), while connecting to hotspots by others.
Phone could connect only if it is very close to the router (couple of centimeters)...which i don't really understand !!
My phone was rooted with TWRP, rune KK 4.4.2 and working very fine for almost 3 years without one issue...this is the first
I tried everything could be done....
- Factory reset
- Rom installation (CM 11.0)
- Stock Rom from sammobile (clean one 4.4.2)
- Even install modem drivers of other revision (don't recall it)
I gonna try marshmallow and see!!
Any other suggestions will be much appreciated..
Cheers,

I'm having the exact same problem!
It only connects to WiFi if I am standing less than 1 meter from the router! (otherwise it sees the signal, even from far away; but fails to connect)
I'm on 4.4.2, no changes for months solid as a rock then this issue appeared!
Any ideas/solutions?
