Wifi Possibly broken

HI
last night i rooted my phone using the exploid x10 root apk, at first it worked fine and so i left is plugged in over night to transfer all my music onto my new sd card
but this morning it seems the wifi has broken
it connects to the network but will not send or receive data, so the browser says no connection, so does the market etc
i have reflashed its software 3 times even downgraded back to the R1, still no luck, its not even rooted and its broken
any1 had the same issue? i have searched the forum but the ppl with the sam issue have not been helped. please i dont want to spend $$ to get it fixed i have no job

Hi.
No problem with the wifi so far.This is strange.
Do you have warranty?
Sound stupid but did you try to reset your router?
If nothing is working you should go to the service.

yea i messed around with wifi router, nothing, i can browse the net on 3g wich is odd, but 3g is expensive so that cnt be the solution. bluetooth and 3g work obv but the wifi cannot connect itl connect to the wirelss just NO datac exchange?

There is someone with the same kind of problem but on an EVO 4g, but i really do not understand what they reply's mean. Maybe you do?
http://forum.xda-developers.com/showthread.php?t=800910
tried to search on google and came across a LOT of people having this same issue, on laptops, iphones, ipads, which lead to the conclusion that it may not be a wifi failure?

well it cant be a complete wifi failure kuz i used the dev menu and it says wlam enabled and scanning just no connection

thanks

+1 and so much more for all your help man
i managed to fix it, it wasnt my device as such it was my router, too so i fiddled around with both mainly giving my x10 a static ip and bam it worked, cheers!!

I too have a wifi problem, but it is quiet a different one and i have no idea how to solve it.
when I connect to wifi at home my router reboots, but there is no such problem when i connect to my office.
I tried reseting the router at home and still no use, once it got connected and when i started a download from the market the router again rebooted.
How can i solve this????

Tried diffrent encryptions? like WPA2 or WEP?
Maybe switch from G to N standard (or vise versa, if availible?)

see: en.wikipedia.org/wiki/IEEE_802.11#802.11g

The X10 doesn't support 802.11n

no one said that it did..
My router uses N and i still connect fine

Somebody told him to try to switch the router from b/g to n. That was the point of my post.
And your router obviously operates all 3 standards at once

Htc hd2 is "attacking" Wifi

Continuation from here: http://forum.xda-developers.com/showthread.php?goto=newpost&t=1183342
I contacted a "usergroup" for my internet provider and they told me the symptoms I'm having are due to the router thinking my htc hd2 is attacking it and so it turns off wifi to end the connection between the two , anybody else had this or would know how to fix this -_-? Changing my security to WEP was suggested but this is out of the question due to it being very unsecure.
Edit- Are there any apps which let you specify which security type you'd like to choose e.g. wpa only instead of wpa/wpa2.

Have you rebooted the router, that would be my first step, and the second, Look for a firmware flash and update if available
Also try the phone on a different wifi set up as it may just be the phone itself

If you mean turning the router on and off yes, the router gets turned off at night anyways - firmware is uptodate and I'll check tomorrow if it connects with another wifi.

The phone does connect to other networks so it is just mine that thinks it's being attacked

Turning your router off and back on is a reboot, indeed, but it works only on windows based devices Try to RESET it (just do not forget to note some sensitive/important information first - just in case you'll need to manually restore some settings).

What kind of crap is it and what version of firmware it's running?
HD2 attacking access-point - that's something new, interesting

The router is Thomson TG587N Works fine with 2 iphone 4,itouch 4 gen,2 laptops and a computer connected to it on wireless with another 4 computers connected by ethernet cable at the same time but when the htc hd2 is introduced just turns off wifi -_-. I've now tried turning off the firewall, IDS,changing channels,turning off security/encryption altogether...STILL NOTHING

Simple way to tell if it does think its being attacked ,,,, it will create an entry in the IDS log. If there is no entry then its a different issue.

In the event log there was an entry for the IDS everytime the wifi went down... Disabling IDS through telnet however did not do anything : - Just stopped the IDS log :S.

...nothing?

Sadly I suspect the router is the culprit not the Phone.
See if there is an earlier firmware you can flash as you have the latest.
No other options sadly
Oh apart from replacing one of them - routers are cheaper (over in the UK anyway)

Help with fixing Wi-Fi

I have reached my wit's end trying to resolve my problems, so I'm posting here for ideas on fixing this, any input is appreciated!
When this started I was on stock, rooted, ICS 4.0.3 and had been for months. My wife has a nexus s with the same config and hers works fine.
Last week, my daughters sidekick 4G stopped having wi-fi internet connectivity. I turned her wi-fi off, then back on and it was fine and has been ever since. Later that night, my nexus did the same thing, the same procedure resolved it. Ever since then, my wi-fi will only work for 1-5 minutes after turning the wi-fi on. This is the only thing I can think of that changed that could have caused this. This was the first night we connected her sidekick to wi-fi.
The wifi symbol is up there, it'll be blue for up to half an hour, but won't have internet connectivity for long. One thing I noticed pretty quickly was that even though the grey wi-fi symbol is there, I can't access the router settings at 192.168.1.1 from the phone. I thought the grey wifi symbol still indicated I was connected to the router still, but it's not working. Each time this happens, I can turn wi-fi off, back on immediately and it'll work for 1-5 minutes. It appears that the more I constantly use it after turning it back on, it seems to maintain connectivity longer.
Last weekend, just after these issues started, I visited my sister and my phone operated on her wi-fi all weekend just fine.
When I came back home, my problems started immediately.
Here's what I've tried in pretty much the order I tried them:
I started by uninstalling avast, facebook, and autostarts
selected "Forget network" in access points screen and reconnected
Factory reset
Wipe dalvik cache & fix permissions
see if it worked without sim card in (it didn't)
flash GB broadcom driver
Switched router channel from 6 to 1
flash stock 2.3.6 (wi-fi problems still present)
flash OTA ICS (still had problems)
flash stock 2.3.6
flash OTA ICS
re-root
Flash PixelROM 1.60 LiteTouch
factory reset router (No wifi problems on using open network and default SSID for 30 minutes!)
resetup WPA Personal security and rename SSID same as before
Worked for another 15 minutes or so after this
flashed stock 2.3.6
flashed OTA ICS
re-rooted
Restored nandroid backup - quit working after this step
Factory reset router - worked for about 15 minutes, I decided I was ok so I setup security and SSID as before, then it quit working again
flashed PixelRom 1.60 LiteTouch
flashed stock 2.3.6
Flashed OTA ICS - THIS time I did not restore my google backups from the cloud, fearing that this was somehow restoring something that was causing me problems. It did not help.
Changed SSID on my router and reconnected phone
I have spent countless hours trying to fix this. I don't believe it's the hardware because the router factory reset seems to help quite a bit, works fine on unencrypted default router settings, and it worked on my sister's wi-fi.
I have nmap and wireshark and have a basic working knowledge of them. I have adb setup and usable on my computer. I also have dd-wrt installed on my router and have for years. Is there any kind of IP or hardware logging I could perform with these tools to help figure out what's going on??? ANY help is GREATLY appreciated!!

Well i'm no expert with any of this, but it sounds more like a router issue.. If both your sidekick and nexus have the same characteristics of failing wifi, it cant be the devices..
If you've already reset your router and it does the same exact thing, maybe it is something wrong with the router itself. You said it connected fine at your sisters house, so it cant be any hardware within the phone.. The only thing I could think of is maybe try a different router in your house to see if it works? If that helps get rid of the connectivity issue, then you can just get a new router and be happy with the wifis

I don't think a *hardware* problem with the router would only affect 1 device connecting to it wirelessly. I would think that kind of issue would affect all devices on the network.
Which makes me wonder if there's a setting on the router that may be causing it somehow, or some combination of packets might somehow cause the router to block my phone.
But again, I'm open to ideas here and I appreciate your input. I think getting another router will be my next step if I don't hear anything better by the time I get my next paycheck.

Ohh, I thought you had said that both the sidekick and nexus were having problems connecting. My bad.
But yeah have you changed any settings on it lately? Or messed with anything related to the router? Some setting may be kicking your device off after 5 mins, maybe some frequency setting or something dumb like that, I have no clue.
I know how it feels to have funky wifi, so I was only trying to help. good luck

Have you removed DD-WRT from your Wireless Router and back to stock OS? I had a Linksys router with DD-WRT and after about 3 years it started working so weird it became useless with any device. Had to buy a new one.
BTW, are other devices connecting fine to this router?
As swamp goblin stated, I would try with a new router.

It sounds like an issue on your router (or AP) with mixed client settings. I have had this issue with an old Netgear AP.
Try forcing "WPA2 with AES only" if all clients support it, otherwise force "WPA with TKIP only". If you have mixed B/G/N devices, force the fastest mode that all devices support. I use "G only".
Then remove and re-add the router on all your devices.
Also check for router firmware updates, and if you use DD-WRT firmware, find the Wiki page for your model and revision and use the suggested build there. The DD-WRT database they have is a mess and should not be used!

I haven't removed it. I thought I had a model that couldn't go back to stock, but I WILL be looking into this. The other devices connecting fine are Sidekick 4G, Wife's Nexus S, Acer Aspire one, HP tx2000 laptop, and my wife's HP laptop. I also have my satellite receiver connected via ethernet.

[Q] Wifi and me - not happening! Piece of CRAP google!

I'm sure I'm not alone in this.
My N4 won't connect to wifi. Well it connects but Won't keep a connection to complete a playstore app install nor update the system itself?
This is what I posted on "Issue 40065: Nexus 4 and Nexus 7 Wifi Drops connection Android 4.2"
New device just received. Will connect to wifi but unable to install any apps thru play store.... Just shows data transferring but none actually happens. I'm unable to install none of the gapps updates. Left it alone for 2 days did not help. removing password from router and making it an open router did not help. Now trying to decide I should return the device as it is only usable as a phone not a multimedia device which this N4 should be?
There are a lot of people having the same kind of issue on this phone. A little search brings up lots and lots of complaints.
Still unable to connect to my router encore model 2AN3.
Tried to connect to open wifi router at McD and [email protected]#$ - still no go. It will connect think about it and stops. The icon at the top turns green and gray and keeps doing it.
How ever I was able to connect to the open wifi router on another Nexus S (my older phone) and was able to download updates and install said applications from play store.
This tells me that hardware is good. Software coded so badly that it is unable to keep a connection to routers.
So if you need to use this phone on a wifi router - wait until google fix this or get another phone.
As for me - it is a shame I will have to return this phone to google as it is useless media device. Just a phone which I can get a cheap phone for 10 bucks not $400 piece of [email protected]#$%T.
Sorry for the RANT.

Also flashed rom CM10.1 stable and xylon 17 stable. Still same problem repeated. both ROMS can connect to my hotspot on my NS but unable to neither my home router nor public wifi.
A few things I have tried.
1. avoid poor wifi disabled.
2. switch chennels to 6 or 8 - tried all.
3. Resetting routers
4. Assigning static IP address
5. Cleared cache from recovery
6. changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
7. Flashed new kernel Running franko.
8. Flashed 2 other ROMS/cm10.1 and xylon17 both stable versions.
My home router have not trouble connecting to all other devices at home (NS, HP touchpad, 3 desktop and 3 other laptops, Tried with N4 being the only device that was turned on. : still no go!! WHY WHY WHY WHY WHY!!!
Also followed the directions from this thread. Still no candy.
Please take a poll and let post here if you should find a good solution.

Mine works flawlessly. You should contact Google for a RMA.

I guess its the lease period on your router that you need to change... put it to lease expiring n a day or two... shuld work.. I had this issue when I upgraded to 2.3.6 on my Atrix

I just called. This guy treated me like I'm noob. But I digress.. He asked me to turn off GPS and try again saying that GPS and wifi together can not be on at the same time. That still did not work. So there is a request for replacement. Not really sure when I will get it. But keep my finger crossed - that I get a working wifi and gps at the same time ??
Don't really want to return it though since I like the phone form factor and such!
What a shame.

You shouldn't be flashing ROMs to try and fix something as basic as this. You're only adding more variables to the problem. My WiFi has been rock solid, and so apparently is that of most other posters. This would tend to indicate that there is a specific problem with your phone.
Unless there is something seriously wrong with your router it's RMA time I reckon.

Just to re-iterate .....
Wifi works if I connect to my other nexus S's hot spot.
Wifi will not stay connected to allow me to go to play store on any wifi router (home Encore ENHWI-2AN3 firmware version 1.1.3 - Mcdee's open wifi and [email protected]#'s open wifi router.) It will connect - get a blue wifi icon with a few arrows ..... but will go to gray and back to blue and so on ....
Waiting for google to make up its mind about shipping me a replacement.

Wifi issue related to root?

Hi Folks,
I have been postponing this post but nothing ive seemed to do has worked. I THINK after i rooted my issues started. I am unable to browse the net or anything when connected to my wifi. I have reset the router, forgotten and rejoined the network with no avail. All my other devices do not have this issue. Im not really sure what else to say so maybe some of you gurus could pick my brain. Though this is a wifi only issue and on this network. When connected to other networks im fine. My setup is as follows. I have a hard line going from the router the ISP provided in the other end of the house to the router in my room. Like i said my phone is the only device that has issues on this network.
thanks in advance.

That's a pretty strange issue, not sure there is going to be much help... I've had some strange, random issues with my S5. I had issues with wireless, xposed and some other apps after rooting the first time. I got tired of it and used Odin to reflash the stock firmware, then performed a factory reset and rooted afterwords. I haven't had any problems at all after doing this... In all honesty, that's the route I would go if I were you. Sorry I couldn't be more helpful, hope you get sorted out

Just wanted to agree with BadKarma on this. I've not had your exact issue, but I have had some similar stuff after rooting originally. I used Odin to go back to stock and rooted again and have been no issues since. Hope it works out. . .

well i used odin and got back but it turns out it seems to be the router? im on stock with no root and still cant access the net or anything else when im connected to the router. any thoughts on this?

Can you reset the settings in the router via your pc?

Try connecting standing right next to the router. I had this issue with my Note 2 and it ended up being a physical issue with the wireless chip or antennas. It's actually the reason I'm not on a S5.

Not that u want to hear this, but I had to replace my router for the same reason. My router would only pick up certain devices, had to do with hardware and firewall security settings.

Ok so i changed to security in my router to aes and tkip and i was able to connect and browse the net and so forth. but i just got home and connected and wasnt able to get access to the net again. i tried forgetting network and re-entering it with no luck.

First and foremost you have to isolate the issue to either ur phone or the router. In order to do that its very simple.... can you connect to wifi outside of your house like starbucks or friends wfii? If the answer is yes than the issue lies solely with your router. Let me know what you find out and I can help guide you <---- systems administrator Also please provide the make and model of your router as well as your modem and your ISP.
EDIT: I just read the line where you talk about having another router in your room. I can already tell you this is probably NOT an issue with your phone but rather your setup. The secondary router must be setup as a repeater or bridge OR on a different subnet. This gets very tricky for average home user and I do not recommend you tackle it on your own. Also your main router has to be able to play nice with the secondary and if it's one provided by your ISP it's probably a POS. Also your phone is probably not the only device having issues with this setup.... its the only one you are noticing having issues. Android OS is very sensitive to weird wifi setups and anything out of the norm will set it off. It's actually a great tool in diagnosing wifi issues.

Hi there thanks for the reply. Yes i can connect to any other router without issue. The router is my Router Info:
Name N300 Wireless Router
Model F9K1002v5 (01B)
Firmware 5.00.15(Nov 1 2013)
Serial No. 12349GC2508237
Boot Loader 0.12
I use my tablet and other pcs within this wifi. It is under a different subnet as well. (i think so been a while since ive done any networking) The main router that comes in has the standard IP 192.168.1.1 and the IP for my router in my room (basically set up like this since my room is quite far and gets bad signal from the main router, Cable in -> Main Router -> Hardwire hooked into a port -> ethernet run to my room -> Connected to a port on the wireless router) 192.168.2.1. My ISP is Optimumn Online. My wifi was working fine until about 10 mins ago. seems to happen so often. I did change the security a while back to TKIP + AES on the router and made sure it was the same on the phone and it was working fine for days until like i said about 10 mins ago.

This leads me to think that perhaps the router (however old or new) may have a setting, or an actual limit, on how many devices connect to it.
If not that, perhaps if you rooted, and tried removing bloat, you may have been a bit overzealous and removed something related to WiFi and are now having this issue as a result.
I have only removed the list of apps and bloat that have been posted on Ricks Rom HERE. The ONLY problem I have seen since removing this list, was that I can no longer access PhotoVault correctly. Gives me an error saying that it has no connection to the database, but my 4G is working fine at the time as I was downloading via steam and streaming a movie, and playing a PC game at the same time...

Hi there thanks for the reply. Yes i can connect to any other router without issue. The router is my Router Info:
Name N300 Wireless Router
Model F9K1002v5 (01B)
Firmware 5.00.15(Nov 1 2013)
Serial No. 12349GC2508237
Boot Loader 0.12
I use my tablet and other pcs within this wifi. It is under a different subnet as well. (i think so been a while since ive done any networking) The main router that comes in has the standard IP 192.168.1.1 and the IP for my router in my room (basically set up like this since my room is quite far and gets bad signal from the main router, Cable in -> Main Router -> Hardwire hooked into a port -> ethernet run to my room -> Connected to a port on the wireless router) 192.168.2.1. My ISP is Optimumn Online. My wifi was working fine until about 10 mins ago. seems to happen so often. I did change the security a while back to TKIP + AES on the router and made sure it was the same on the phone and it was working fine for days until like i said about 10 mins ago.

You have the right setup with a different subnet. It's possible the main router is assigning the same IP address that your router has to another device. It would be best if you picked up another router that has repeater capabilities and set it up in repeater mode. Also reserve an IP address for your router from the main router to avoid IP conflicts.
Another possibility is simply the wifi on your router is deteriorating and it's time for a replacement. I recommend the Netgear Nighthawk R7000 if you don't mind spending the $$$. If your on a bit of a budget the Netgear N900 (WNDR4500v2) is the next best thing that supports repeater mode.

well its been still working intermediary. I have to unplug the router and plug it back in then i can browse the net on my phone. idk if id like to lay out that kind of money for a new router. there has to be something else thats causing it. i set the router to reboot everyday, also my phone. its odd though. sometimes it works sometimes it dosent.
