VERY Strange WIFI problem

Ok
so for the last couple of days I've noticed that when at home, if I turn on the HD2's Wifi, my entire home network stops working. The router can no longer be accessed, even by wired Ethernet.
I figure it was a router issue, so I bought a newer better one by a different company - and what do you know: The same problem persists! As soon as I enable WiFi in my HD2 the router becomes unaccessible - and as I turn it off, all is well again.
I'm a computer technician, an MCSA and usually pretty good with those things, yet this issue baffles me. What on earth could cause that?
No other WIFI devices cause this issue, only my HD2.

What is the radio firmware version on the phone and what is the make, model and firmware revision of the router.
2 IT engineers are always better the one

My older router (with same problem) was 3Com 3CRWER200-75.
I replaced it with an Edimax BR-6524N. Same weird issue.
Both have latest firmwares.
My phone radio version... To be honst, I don't know how to check. My ROM version is 1.48.405.2 (71294) WWE - which is the stock rom of the Israeli version as supplied by Newpan.
Also worth mentioning, this didn't happen until a couple of days ago. Everyting was fine for months with the same exact configuration. SOMETHING must've changed, but what?
And how is it possible for my phone to kill two different routers?

I have the same problem with my laptop when running windows 7 but not linux....seems too me at least my problem is a driver issue.could be the damned for you too possibly. Was there a possible divert update on your phone?
I do not have an hd2 so I am not sure.
Edited for auto correct mistake

You check your phone radio revision the same way you check your rom version. Go to settings, about phone, software information and look for the line "radio version".
Your actual rom version is quiet old and if you are still using a stock rom then you may want to have a look at the htc website for your country and see if you can get 1.66 rom or newer.
I personally have never experienced this problem but i always use linksys or netgear networking equipment. The linksys router i have at home i've had for many years (it's a wrt54g v2.0) and it still works perfectly even though it's cpu and networking chipsets are overclocked and it runs a custom firmware.

Well, the ROM is the latest available for my country :-(
But anyway, I managed to solve it by deleted all my wireless preferences and just 'rediscovering' my home network from scratch. Surprisingly that worked and solved the problem, even on my old router.
Now I'm wondering if I should return the new one and stick to my trust good old one, or stick with the new one? It was pretty expensive, and I don't really use an N wireless connection anywhere anyway, so... What do you think, XDA?

You have no need for it, get your money back.

the hd2 is capable of N speeds. You just need to enable it in the registry. Personally i would use the old one till it dies and keep the newer one in a box till then but the choice is yours

The newer one is a lot of money I spent for something I didn't even need eventually. I'll be turning it back, I think.
Thanks to all who helped You guys rock!

great to hear that you've found a solution!
A thought came to mind while reading this thread.
Wonder if it's possible that a certain radio file/setting on your HD2 might've been corrupted and instead of generating the usual wifi signal, it could've generated a signal on the same frequency that completely jammed you're router signal?
Similar to the radio jammer units available in some countries that can be used for GSM, Wifi, etc... just a thought!

Im glad you brought this up because I had the exact same problem (accept I could connect via ethernet just wifi went dead), almost brought a new router after spending 2 days trying to set it up :/ It wouldnt allow anything to see the router wifi wise let alone connect to it via wifi. I havent turned my wifi on the phone since then but ill try reseting my settings later to see if that works. I didnt wanna risk screwing the router over lol. Im on stock 1.48 rom and radio on o2 as well

That's an interesting thought, and if it's true - reversing it could be a tool for evil - just imagine being able to shut down networks just like that...
Anyway, I'm glad my issue was solved. That Edimax N router is really expensive, and I like my trusty old 3Com way better.

My N*kia n95 used to f*ck up the router like this sometimes

[Q] wifi problem solved?

hello there,
this phone is just released in my country. i would like to buy it but i found this video on youtube: http://www.youtube.com/watch?v=ptg6cLdA9OU
is this problem common? is there any software to fix?

this video is too old (the rom is B133), i used both B135 and B136 now, with no Wifi probs at all

that's great. thank you.

I agree. I am also on B136 and no issues at all with wi-fi. Good Luck. I think it is a great phone especially for the price.

B136 is the pre installed ROM?
Or in other words: people that buy the Ideos X5 today will not have any wifi connection problems?

Obviously I can only speak from my experience with my own phone, but it came (3 months ago) preinstalled with B133 and did an update over wifi in the phone's update options and had no problems before or after the update. The update was about 3 weeks ago for me and I have been using the wifi almost every night since I go the phone. I am very happy with it

Can warmly recommend this phone, its great !
The price is nice, the quality is fine and the phone is getting a larger community !
If you find trouble with old firmware always update to the newer ones !
Grab them at Huawei and upgrade your firmware, they have a guide included on each firmware download pack you download.

Agree without doubt. I never experienced wifi connection problem. But only some education institute use PEAP encryption may post a problem with most Android, though not the phone itself .

unfortunately its the phone thats causing wifi dropouts in my case..
i can connect to my wifi router with my iPhone 3GS, my notebook, my netbook, my NDS, etc.. in fact X5 is the first and only device that has connection problem with my wifi router..
though i like this phone very much, i can honestly say that wifi problem does exist, at least in certain instances including mine..

So it has been established that this phone sometimes has wifi issues. The question is; can they be solved? and how? anyone got any experience in that area?

I'm on B136 and WiFi is still broken. B136 seems to have made Wifi connections a little bit more reliable, but it still drops out pretty regularly, usually when I try to update more than one app at a time from the Market. In the middle of the downloads it stops because the WiFi has become disabled and has to be restarted again.
It's less of a problem when there's only one update to download, but if there's two or more it happens quite frequently. It also still sometimes happens (though perhaps less frequently than before B136 was released) while it's not downloading anything, just sleeping (I have it set to not disconnect when asleep) or awake and connected to my WiFi network.
The unreliable WiFi connections are one of the two worst problems with this phone (the other one is the wildly variable battery life).

Nobody has a definate solution to this problem?
Is it part of your insurance btw? it is clearly malfunctioning and perhaps should be fixed by the company you bought it from...

i am using genokolar's b137 and wifi is fine ( i had problems before with stock 135).

Where are you download this custom rom? I only find one V8 in chinese forum. Is this, you'r talking about? Is this multilangual?

yep this is it!
every android version is multilingual!
thats his latest version:
http://bbs.goapk.com/thread-3177723-1-1.html
also use the google apps (GMS) from here:
http://bbs.goapk.com/thread-2875088-1-1.html
be sure to have this installed before doing anything:
http://forum.xda-developers.com/showthread.php?t=1130524
if you find it hard to download them from there i have uploaded them here:
http://www.megaupload.com/?d=IMZBGHIA (use the gapps that are inside this rar)
http://www.megaupload.com/?d=3DOP0APD (use this rom)
i have removed some apps he put in there (like nofrills[something like set cpu], a chinese market etc) to make it a total stock rom. just be sure the 1st app you install is Superuser.

I did some tuning to my wifi configuration file and that's all I did to solve connection problems. Just take a look through my thread in the general section with subject title "Wifi Client Tuning ... Solve Connection Problem "

Wifi connected but doesnt work.

We have 3 SGS2 at home and a Billion 7800N modem
There is a recurring problem on my wifes phone where there is no dataflow. I cant even reach the modem. It will just start working all the sudden for a short period then stop again.
Things I have tried.
1. Using it right next to the router
2. have tried using different channel
3. have reset modem
4. made sure sleep policy is on never
5. Update firmware and hard reset phone - no new apps installed - worked at first but now having problems again.
It never loses wifi connectivity....internet just does not work. Turn 3g on...works fine.
What could be the problem?
Only things I can think of
1. Faulty phone
2. Virus? That phone is sometimes used to check out Chinese websites...and I know some of them can be dodgy. I forgot to ask her not to go to any of those sites after the hard reset as trial and error.
3. Not certain but this problem may only started when we updated to 2.3.4.
If need be Ill hard reset AGAIN when XXKG6 is out - I dont want to flash back to 2.3.3 to try

I have the impression, that the Broadcom WiFi drivers of Android are still buggy, because my Asus Transformer's WiFi also isn't very good.
When using a static IP address and setting Google's free DNS 8.8.8.8 as a secondary DNS server (the router as primary), my SGS2's WiFi works best.
Maybe give it a try.

I have the exact setup and tried all the things you mentioned to no avail. It works sporadically after I reset the phone wifi on and off but it won't maintain data connection for long. Although the signal indicator says it is still connected. the billion 7800 works on my wifes sgs and connects without problem to my work htc legend.

If you google for "galaxy s2 wifi no internet", you'll find out, that several SGS2 owners have exactly the same problem.
I all cases it seems to be the router's firmware, that causes this problem. I found two users reporting, that the only solution was to download a new firmware from ...
http://dd-wrt.com
But maybe it helps to drop the speed from 802.11 N to G?

I have the exact same problem and my firmwire on my router is the latest. What I do to fix this problem is just unplug my router and plug it back in. I find that fixes it for me. Post back if that doesn't work

That's why two guys reported, that they had to download a new FW from DD-WRT, which solved the problem for them.
Sorry, that I don't post links ... it were german forums.

I have the exact same problem. You say that the other two S2's work perfectly? If that's the case then it must be a hardware fault. I'm gonna take mine to be fixed or replaced.

Likely ... maybe different firmware?

Yes....my SGS2 and my brothers work fine. When I update....I update all 3 so we are all using the same firmware.
Thats why I believe its a problem specific to 1 phone....not the router (although I did update my router to latest firmware just in case.....same problem)
As a side note - my brother has a microphone echo problem when using a specific gel case. When my wife and I use the exact same case - no problem. I dont know how Samsung build their phones - but its not very consistent.

That's why we have a thread about the "Made in ..."
But that's not only a Samsung problem ... I know that from the Asus Transformer forum.

Ill see where our phones are made if I have time. If anything though, my brother should be the odd 1 out as his was bought in Australia whereas I got the other 2 from UK.
Ill get to the bottom of this....even if I have to keep doing hard reset and trial and error tests. Not being able to use wifi is a huge deal.

Just to confirm, the problem's not only apparent in 2.3.4. My phone has the same problem with 2.3.3. I've sent my phone in for repair now so i'll post my findings here in a week or so. Have you got any further with it?

I sure hope they do fix it somehow....It's becoming increasingly annoying having to flick wifi on and off, downloading apps is the worst. This never happened on mine or my girlfriends htc's.

Anyone able to find a solution for this problem? Just picked up my Galaxy S2 and have the exact same issue Wifi connects, surf the net for about 10 sec, then nothing.. still connected to Wifi and everything.
At work at the moment so can't really play around with the router settings but will try once I get home. Have been looking forward to getting this phone for a while now and to have Wifi issues right off the bat is quite disappointing..

wifi connected no data flow
i had the same problem
i tried different ways no sucess
i tried Set DNS Pro from market
tried different settings
applied different dns
shift from open , custom to google ang keep checking the internet in browser
after few try it works everytime
its to do with assigning ip address in android
thanks

I posted a solution a few weeks back....but i think most people overlooked it....so the solution is
Go to settings>>>>wireless and networks>>>>>wifi settings>>>>hit menu and go to advanced>>>>regulatory domain>>>>change the channel to 14.....thts it....it worked for me on vibrant,nexus one and even on sgs2..hope this helps

Channel 14 is not allowed in most countries ... my german router e.g. doesn't have channel 14, only 1-13.
I had similar issues with my Asus Transformer and found out, that a static IP works best, BUT only if a secondary DNS is assigned too. I used Google's 8.8.8.8
Give it a try. The Broadcom drivers seem to have a bug, when no secondary DNS is assigned.

The "regulatory domain" setting isn't there on my galaxy s2 ;/ Will give the static IP solution a try.

Wifi problems with latest rom ICS, an idea!!

I notice that a lot of users have problems with "death sleep of wifi" on the new ics rom.
So i remember that when Samsung Italia roll out an update to 2.3.6 (KK1) a lot of users experiencing same issue as ics or even worse.
Then samsung italia sudden release the xila firmware to resolve these issue.
The issue coming from the fact that several models of I9100 have the wifi chip from
Murata Manufactoring
So everyone that have this issue should go on http://hwaddress.com/ and paste his mac address found on Settings -> Info -> Status
I try but i have one from Samsung Electro Mechanics

Mine is from Murata and I am experiencing some problems with Wifi
The only solution is to wait for a new firmware?

For now is only +1 to Murata

Well I have a Murata chip but I do not experience Wifi issues.

I have Murata and didnt recognized any issues with Wifi?
What exactly is the issue about?

Well i'd like to know chip version of People that HAVE THE ISSUE.
Not those that have not it
In anycase issue is that wife toggle stay forever with connecting...and the only solution is restart.

Exactly what happens to me. It does not happen very often. I would say it happens once a week, but it is still annoying.
I suspect that it could be something related to when you enable or disable WiFi with the 3G connection enabled. The WiFi icon freezes and the only solution is to restart the phone.
Another thing is that I used to connect to my MacBook through WiFi using GingerBread without problems, but now with ICS the WiFi disconnects from time to time.

Mine is Samsung Electro Mechanics and have the wifi problem since upgrading to ICS. Basically, sometimes I will turn wifi off but when I turn it on again it won't do anything until I reboot and only then will it connect. I think this is the same issue being experinced by many. I think its just an ICS bug with SAmsung's releases. Hopefully future releases will fix it

Are you guys having this problem all the time? Mine is random. I could go most the day turning wifi on and off and not have the problem and then all of a sudden it will not be able to turn on. I am on LP4 build

I had this issue while on ICS, now back to GB. I have Samsung Electro Mechanics btw...
The problem was random and sometimes I was able to get over it by turning WiFi Direct on and off for a few times.

Hey there, i have Murata, i had the issue.. untill i switched to the latest siyah kernel (later then 3.0.1) since then the issue is gone, give it a try!

i have the murata chip, i am using lps and i was forced to move the router to wap only, in security settings of the router, in order to connect to the wireless network

i have murata, and i had that problem when I installed the second beta of ICS
and so far, no serious problems with wifi, nothing that a change of modem does not solve

The only thing i did with the Hydrogenics ROM, i disabled the 'Network notification' in Advanced (wifi)

Wifi is handled by the kernel (library) and the rom (Drivers)...

Galaxy S8 WiFi issues after Oreo update

Hi,
I just received the Oreo update for my S8 and everything seemed fine from the start. It didnt take long though when
I noticed that the WiFi was acting weird. Even though I had great connection to my modem, my WiFi performance
was extremely poor. The two arrows beside the WiFi logo in the status bar only showed upload and no download when I
tried to open a website. I tried forgeting the network but it only seemed to work momentarily. So I rebooted my modem and
hoped that it would solve the problem. Rebooting the modem only worked momentarily too. I will be checking later if this issue
continues with other WiFi networks.
Has anyone else experienced this?

Same problem with My S8 after Oreo. Occasionally the !-mark next to wifi-symbol and the connecton is lost. By restarting the wifi-router or renewing the wifi connection from the phone fixes this for some time, until it happens again.

This fixed it for me
Mine was doing the same but noticed I could stay connected to a older router I use as an extender so changed my wifi security on my main router from wpa2-aes to the older wpa and it's been fine ever since stays connected on 2.4 and 5 now

Is there a fix for this yet? I just downloaded the newest update they rolled out today, 4/3/2018 and I still cannot send email if I am connected to my wifi. It tells me "couldn't send" and it sits there until I turn off my wifi and use my data. This is ridiculous. My wifi connection is fine. I should not have to turn off wifi every time I want to send an email. So frustrated. Why roll out another update so quickly if not to fix the issues the March update caused????

I am also a an S8 user and noticed my wifi dropping connections throughout the day and reconnecting. This has occurred ever since Oreo update. I have tried all the possible fixes and none of them seem to work. I have sent my phone to Samsung for a repair and they have useless approved centres that lie about fixing the phone. I have sent it back. Lets see what happens. Worst case scenario I will have to install Nougat as it was working fine on this version.

Same here ! =(

Same problem
Sporadic exclamation mark on the WiFi icon
and poor performance .
Opened another thread on too many open ports.
Used sockstat and too many ports are listening.

Me too
(ROM France : XEF)

Did you guys notice this after the Oreo update or on Nougat as well?

I’m having this problem since the Oreo update too. I have to turn the WiFi off and on several times a day to fix it. When attempting to use WiFi, no pages etc will load and then eventually a ! Symbol appears next to the WiFi icon. Only fix is to turn WiFi on and off. It’s very annoying!

Exact same issue. Started occurring right after oreo update

Have you guys complained to Samsung about this? as making noise to them will rectify your faults eventually.

Same here, WiFi unreliable since Oreo. I need to restart the network to make a WiFi call and that isn't always a reliable fix. I started a chat with T-Mob on FB and gave up. They're clueless. Samsung S8+

Hello same issu, I'm from France an online the forum in France an Germany many people have this problem.

I read somewhere to delete the wireless connection from your device and then re-add. I'm not ready to say it fixed things but the WiFi does seem more stable.
UPDATE - Sorry to say there are still issues. Oh well, it gave me hope for a brief moment!

Go to settings- General management- Reset- Reset network settings- Then confirm and restart the phone. After re add your wifi networks. That fixed it for me
Update: It turned out that it didn't work for me... it looks like i may have to try and factory reset as it feels like i have tried everything else :crying:
