[Q] Having bad wifi since I flashed DD-WRT on my router - Android Q&A, Help & Troubleshooting

Hi,
I had no problem whatsoever with my network since 2 days ago when I flashed my dlink dir-300 with dd-wrt.
Since then, I started having problems using my banking app (it gets stuck sometimes during account data retrieval) and more consistently the XDA app fails to retrieve data most of the times.
The rest seems to be ok (on browsers I did not notice connection problems), even though the wifi signal (icon) appears to be quite low even when I am a few meters from the router, while all my other devices (laptop, iphone, blackberry) are working fine.
So, I would need some help to troubleshoot the problem, for example how to check where it gets stuck in the XDA app could help to understand where the problem happens.
I think I set the router with the same values it had before, and I had more trouble with previous FW, so I won't go back there, but I could still try to change some setting if there is some "known" wifi issue with Android devices.
I have a Nexus S with Cybergr v11 ROM and Matrix v19.5 kernel. I repeat, now all other devices are working fine, and this phone was working fine until I flashed the router, so it must be most likely a bad combination of wifi settings (I tried a lot of them already) and Android.

X10 wifi SCANNING - DISCONNECTED loop! HELP!

Router information: Linksys Wireless-N WRT120N
I have done everything that i could think of to get this working. i have done several google searches and they all say to do specific things.
For example:
-Reset router
-Enable B/G only or G only set at channel 11
-turn off router firewall settings
-and a bunch of other random sh*t
i have done all of the above then some and i still cant get it to connect. all i get is *scanning* then *disconnected* thats the only two things it says. except right after i reset the router. every time i reset the router i get * obtaining IP yadadada* then goes to *disconnected* then back to the "scanning, disconnected" loop.
there have been some people that have said flashing a custom firmware on the router would fix the issue with mobile connectivity on Wireless-N routers.
please someone be helpful with this and please dont tell me i need to reset my router. i have asked this same question on several forums and the only replies i get are "if you reset the router and turn off security it WILL work fine" thats bull****. im not an idiot. thats the first step any computer literate person would take before asking questions.
**Update: same as from General thread. i had to repost because it was closed for some reason there. also here are the answers to the other two guys to responded.
"not standing close enough" -i have been standing next to it. i have yet to test it more than 10 feet away lol so it cant be there
"flash another rom or reflash current rom" -it has nothing to do with my rom, kernal, or radio. this issue is also happening on my girlfriends xperia running Wolfxperia and mine is the blackeditionHDv2. its also an issue with her sisters xperia. hers is still stock 2.2(i think). their stepdad has an iphone and it wont connect with that either. from what ive gathered... its a mobile issue. i know all these phones say (b or g only) but even setting the router to broadcast in b/g it still wont connect. it notices the routers name with full strength on all devices. also i might add that their laptop is an older laptop. does not support N but still can connect to the router and have internet.
Same here. Xperia mini x10 pro. When on it says connecting even thought I nothing appear visible.

*sorry for hijacking your post ts*
as for me it just started, before that when i was at col i was able to watsapp as usual, the phone is currently not with me but when i get i will post some ss for you to see.
-------------------------------
Here are the ss
any idea on how i can solve this?
I'm guessing this is an ip issue. The mobile devices are not able to get one. This usually happens to me on a public network and I even get a " limited or no connectivity".
The work around I do is to assign a static ip on my phone. Its very simple to do and if you need help doing it, let me know.
There's no clear explanation I can tell you, but it seems some mobile devices have a hard time pulling ip's from different types of routers. Hope this helps.

Will ask my gf to give it a try. It happened so abruptly, it was working fine when she was at col then when she came back it won't detect any wifi, whether it's her house or mine, and now that she is back at her col she still can't connect.
I know how you feel.
I have had this issue ever since I first upgraded to Stock 2.3.3 last July. On 1.6 and 2.1 (both stock also) I never had issues.
Basically, in my case, resetting the router DOES solve the problem, but only for a limited time. This limited time is random, as sometimes it will work for a few days, and then sometimes it will cut out a few hours again after I have reset my router. I am also using the static IP method (and an app called WiFi Stat which I initially thought had solved the problem, but it hasn't) I'm not sure what triggers the WiFi connection to be lost, but there must be a trigger. Like I said, I never had this issue in my previous old Android versions.
I had hoped (somewhat naively) that moving to a custom ROM would solve the issue, but after installing Wolf's latest ROM, I still have this issue.
Have you tried anything based on 2.3.4 or above, to see if this is an Android 2.3.3 issue? Are there any good ROMs people could recommend that are based on higher versions than 2.3.3?
WEP/WPA key issue?
If its not the kernel/ROM/version of the phone, it could have something to do with the way the security is set up for your router. I had the most frustrating time logging into my university's wireless (think it was encrypted with 802.1x EAP) which required username and password. Though most home-owned router are equipped with WPA/WPA2 PSK or WEP, you can try the steps below:
1. Go to Settings ->Wi-Fi Settings -> Add Wi-Fi network
2. Type in the network SSID (yeah this is the manual part)
3. Open the "Security" drop-down box and set the following:
Security: 802.1x EAP
EAP method: PEAP (default)
Phase 2 auth.: MSCHAPV2
CA cert.: leave unchanged
User cert.: leave unchanged
4. Type in username (if any) and password.
Once again, this would work 99% for 802.1x...not sure about WPA/WEP. Good luck!
Try Channel 6 in router option and hope it works.
Solve
setting a static ip doesnt seem to work.. any idea? i wish not to re-flash as i dun think that would be a permanent solution.
again i dun think it has anything to do with my router as other gadgets are able to connect with it and i didnt fiddle with the security.
It is unable to detect any router as i have tried it different hotspots.
Hope to get some help.
------------------------------------
I wipe clear the settings and it worked again.. hope the problem doesn't persist again.

[HELP] Ray WIFI and GPS problems

So I've got my Ray for a few months now, but ever since I have problems with the WIFI and GPS connections.
GPS:
I used to use Navigon on my Acer Liquid, but that app doesn't work anymore unless there's an active data connection and I don't have a data plan. Now I use CoPilot Live Premium 8.xxxx. App itself works well, but the GPS signal get's lost every few minutes and I have the feeling this is getting worse. Especially in cities it's posible I have to wait for like 15 minutes to have a signal and after that the signal gets lost every 2 minutes or so. Is this just due to a poor GPS receiver in the Ray or what?
WIFI:
I can connect to my router (WPA2-Personal AES) but only for 2 minutes. After that, the icon in the status bar shows that my Ray is still connected to the router, but there is no internet connection anymore, eg in the market pages keep on loading most of the times without saying the connection is lost or so and I have to turn off WIFI and turn it on again after a minute to have it working again for 2 minutes -_- If I do this a lot, it even kicks my computers of my network and I have to reboot my router
I hear there a quite a few problems with the WIFI in kernel related situations and it's often solved by using a custom ROM, but I would like to stay on stock ROM.
What could be causing this? The router, the WIFI security...? I didn't have the chance to test it on another router, maybe tomorrow.
Any help would be appreciated!
For the wifi, if you could test it on another network, we could know if the problem comes from your phone.
For the GPS, if your phone is rooted, I suggest you this application, with every Android phone I have I use it, and I have a some-seconds signal acquisition. It may fix your problem, but I don't understand its origin.

Thanks for the app tip, I will try it!
Try sygic for navigation. It's free and for now it worked with no problems for me.
I have some problems with wifi too. At home i can connect to the router freely, when using my laptop as router it shuts the laptop down, at friends it restarts his router it almost looks like Ray is to aggressive when connecting.
I looked into the problem again today and finally, I got it working.
The things I did:
1) Router firmware update (Dlink DIR-615)
2) Removed Ray's DHCP settings from the router and added them back manually so it never expires.
(Up till this point I still had the same issues.)
3) Changed the WIFI mode from N and G mixed to N only
=> PROBLEM FIXED

The wifi disconnection is genuinely present when i am downloading torrent files... It just kills the connection then connects again... I literally can't download any torrent files especially larger ones like movies etc...didn't have this issue when i had HTC sensation...

[Q] Internet stopped working on wifi on .73 SG build

This is most bizzare. My internet on wifi was working fine until last night, but it is not working any longer. Works fine on 3G though. On wifi I am able to see connected devices on the local network and play files off my HTPC but internet browsing, google play store or anything that uses internet has stopped working and times out. All other wifi devices in my home are fine. I have reset the wifi router as well, nothing. Tried to disable and enable wifi on the phone and restarted a few times as well. Cant really put my finger on it.
Any ideas?
I updated to the SG .73 build about 3 days ago. I noticed batter battery life, no where near what I was used to on my GS2 though.
Anyhooo, any ideas guys, I am concerned.

That's unlikely to be your device. Probably the router or something.

I have also messed around with the wifi sleep policy. No issues there. Power saving is also disabled.
Could it be anything else? An app maybe? I will remove the most recent ones and report back. Badass battery monitor was the last one I installed.

Hi, along with that also try to connect to some other router and let us know if the problem persist.
The wifi connection remains active but no internet. Just thought I would add. I will connect to another wifi hotspot. My wife's GS2 tethering and report back.
I assume that you got "limited connectivity" problem.
If my assumption is true then you should try checking in your Wifi router setting, set encryption method to AES. The problem was addressed when I tried doing this and in addition, changed my Wifi channel from auto to a specific channel.
Right, not sure how this all started but like many others my internet connection (More specifically over wifi) just randomly stopped. After a fair bit of reading on both these forums and Sony's own forum, I downloaded and installed an app called WeFi Pro. Somehow this seemed to fix everything and now have a working wifi internet connection again.
Will do some more reading into this but as a fix i'd recommend installing this app. Oh BTW its free so its a win all round!!

My router hates my phone? Or my phone hates my router?

Ok, so here's the deal.. I have a DLink DIR-300 router... Ever since I moved to ICS (stock and rooted) on my Galaxy S2, I always have some difficulty to connect my phone to the router...
I get "authentication error" or simply try to connect but then stops trying.
There are only 2 ways to fix this:
1-) Forget the network and turn WiFi off during some minutes.... Then turn it on again and reenter password
2-) Reboot my router
This only happens with this router (which of course drives you to think that's the source of the problem) but the weird thing is that my two brothers also have a Galaxy S2 and have no problems (using different roms)
Any idea of what might be happening or how to solve this once and for all? Additional data of my phone:

Make a nandroid backup of your current setup & try one of the roms your brothers are using & see if it fixes the problem. Could be an issue with the WiFi drivers in the particular stock rom you're using not playing nice with the router.
If it's OK for you using one of those roms but you really want to stay on stock, keep trying stock roms until you find one that doesn't have the problem.
They're the things I'd try if I were facing that problem. A router firmware upgrade might help as well, but given only one phone out of three is having problems, I'd try the above first.
Could it be that one of your brothers blocked you on the router?
There may be a limited set on how many wireless connections your router may be set with and yours has just went over the limit.
You could try using a manual IP, Gateway & DNS rather than DHCP settings that the router would give you.

[Q] WIFI home network slows down drastically when wifi on phone swithed on

Hi friends,
My Xperia Z2 is about six months old. Since last month its giving me a hell of a problem with WIFI. Whenver I switch On wifi on the divice, it slows down the internet on the divice itself further also slows down the home network speed (9Mbps to 1 Mbps and gradualy 0). When I switch off the wifi on my xperia, all other divices works great.Initially I thought its my modem issue, hence got a new modem and still the issue persisted. Furthermore this issue occurs intermittently -twice on thrice in a week and persists for a day or two, then suddenly runs fine.
Steps performed already:
1. WIFI and router settings are ok. Infact installed a new modem.
2. Phone repair and software update done on PC companion. ( Whenever I do this, it runs ok for a couple of days and then back to square one).
3. Tried using friends home wifi network and similar experience.
Had any of you guys encountered this issue. I have been asked to send the phone for warranty repair. However I am afraid, since the problem is intermittent , hope the repair guys would actualy able to find the issue.
Thanks for your help,
Regards
Abhijeet
any help friends?
Thanks
Try using a firewall app like AFwall+. Block everything and start unblocking your apps one by one. See if there is any rouge app in your phone
Good luck!

Also check to make sure you don't have conflicting ip addresses. My router would assign my phone and laptop the same ip address which caused issues. I manually set my phone to an address outside of the dynamic range.
