[Q] Strange wifi problems - Kindle Fire General

At some point today I noticed every time I tried to go to google play it would tell me I had no connection. I would try to reconnect, reset my router, reboot the kindle, nothing worked.
Later I noticed only certain apps were not working. When I launched dolphin hd I was able to browse pages, but I am getting a lot of invalid certificate errors when I do so.
My kindle is rooted so I connected to it via ssh and ran tcpdump and I can see data going in and out fine via the browser. However when I try to to monitor port 443 for google play, gmail I see the https traffic, but both google play, and gmail are saying "no connection, retry"
I'm able to ping gmail, twitter, I can browse google. Any ideas what might be causing this?
Oh, also tried fired up twrp wiped my cm7 install and tried to load a old backup, same problems.

maybe blocked some ports on the router ?

I went all through the router settings at the start, even tried connecting to some open wifi thinking it had to be my router, and I have the same issue regardless.

i've had the same exact problems. idk what to do. it wont let me connect to the internet using any app except the browser and there are so many errors with certificates.

Hmm did you try clearing dalvic cache of reinstalling rom.also what rom are you using.

Skyfire will connect to internet, NOTHING else on my phone will??

This is very odd. Suddenly today I'm getting connection errors (GPRS) on every program on my phone EXCEPT for Skyfire. Skyfire can connect and surf the net with no problem, but not one other app on my phone will connect to the net, and I've tried several browsers as well as apps that connect directly (i.e. YouTube, Google Maps, etc).
I'm on AT&T in the US (New Orleans, specifically). I've checked and triple-checked my Media Net connection settings, and nothing has changed that I can see since the last time I was able to use it successfully. I've soft-reset several times, to no avail. I don't know if this is an issue, but while I was using WiFiWMRouter yesterday, it crashed. But I used the "Reset All Settings" function of that which is a crash cleanup of sorts, and still no luck.
What else can I check? It would seem that if it were an AT&T issue, Skyfire wouldn't be able to connect either!
Weird, I have the exact same problem too. I probably wouldn't have known that Skyfire could connect until I saw your post. My problem began (I think) when I uninstalled WMWifiRouter last night. I haven't gotten a connection with any other app since then. I had a hell of a time uninstalling an old version or WMWR I had installed just so I could install the PAID version and now it is apparently causing problems even on uninstall...
To add to this - I've confirmed that devices connected with ICS can connect to the internet through the phone. So it seems to me that the problem is related to some wifi settings (maybe that WMWR sets up) that aren't being "released" when wifi is turned off/disconnected.
If I do a hard reset the connection seems fine. If I then restore a backup from right before the problem started the connection is okay, but only until I try wifi again. From then on it's borked until I restore the backup again... frustrating as hell.
FWIW - I think I pinned down what was going on with my phone. In my wifi settings something (probably WMWR or Phojo) had set a static IP when establishing an ad-hoc network and didn't revert to "obtain an IP address automatically" when I quit/uninstalled the program. I don't know why the IP address of the wifi network adapter affects my cellular data connection, but setting that to "obtain automatically" and turning wifi back off allowed my phone to connect again. So it seems like it was using that IP address regardless.

[Q]gmail and market app not working on wifi

Hey guys, I am facing a weird problem after updating an OTA released yesterday by HTC (2.2.1). My gmail app and market app is not working when on wifi. It works perfectly on Mobile data connection though (EDGE). I get a no connection error in gmail and network error in market app.
I have done the following but to no avail.
1. Soft reset and boot into safe mode.
2. Uninstalled task killer app.
3. Deleted all data for these apps and updated the gmail app and setup the account again.
I have not tried the hard reset as yet. Can anyone help me out please? TIA
Thats not good at all. Is your handset branded?
Hey Andy,
Thanks for replying although your reply does make me nervous :s. I am from India and we only get unbranded sets here. So to answer your question it is a unlocked unbranded phone running stock firmware.
By the way after I posted the question I did get these two apps working once for sometime but since then it's the same problem. I am starting to wonder whether it has to do something with the wifi although all the remaining apps are working fine and dandy.
Is the wifi access point owned by you? You could try turning it off and on again, that may help.
Have tried that. It is my home network that I am connecting to using a linksys wireless router.
UPDATE - I connected my phone using internet pass through i.e. sharing the internet through PC via the data cable and I still get the same error which leads me to believe some setting on the router provided by my ISP is causing this. Although what I fail to understand is that it was working fine till yesterday and nothing have been changed in the router setup recently.
Hmm... that's odd. Did your ISP supply your router? My ISP pushed a firmware update to my router about 8 months ago that broke pretty much everything wireless.
Is it just Gmail & Market that don't work over wifi? Does your browser and other apps work?
Yes indeed, my ISP provides a router which is then connected to my wireless router. The strange thing is everything else is pretty much working including gtalk.
If your router supports DMZ and you know how to set it up, you could try putting your DHD's IP into the DMZ to eliminate the possibility of your routers inbuilt firewall blocking Market & GMail.
Maybe a DNS problem? Ensure you have good ones... You can always test Google ones 8.8.8.8 and/or 8.8.4.4
Thanks for showing interest guys. I for some strange reason cannot access my router settings page. I will figure that out but the stranger things are happening with my apps. After a bit of tinkering I have found a behavior which stumps me.
These are the steps I follow:
1. Sign out from gtalk.
2. Go to manage applications and clear cache and data for gmail, market, download manager, Google backup transport, google partner setup and google services framework.
3. Restart phone.
After this my gmail app starts working on wifi but talk does not start anymore and market also throws an error before even accepting the terms. I uncheck and check the background data services and I am back to square one i.e. gmail stops syncing saying no connection, gtalk works as usual and market starts giving connection error (after accepting terms).
I seriously think now there's a serious flaw in the software and not something to do with my router settings.
Sorry for the long post. Thanks for reading.
Simillar problem appeared for me in Locations. I couldn't list country maps for preload on wifi without 3G. After turned on 3G, it listed the maps - turn off - and i could download with wifi.

[Q] P6810 unable to access any search sites (google.com, bing.com etc)

I have a P6810 I bought from expansys-usa, importing to the USA a device that is not normally sold here. It worked fine for a while, and I very much enjoyed the device.
Then something very strange happened and every time I used the google search bar I got a "Connection to the server timed out" error. Then I tried to go to google.com directly in the browser and I also get the same error message. I tried other search sites bing.com, yahoo.com and each with the same result "Connection to the server timed out"
Other websites (E.g. bbc news), apps including the google play store app (but not play.google.com through the browser), gmail apps etc all work fine, it's just the search sites.
I tried a factory reset and started completely again, the same thing. I rooted and installed a custom rom (Noob 2.1) and the same thing.
I have a galaxy nexus on the same wifi network and that works fine, I have PC (Windows and mac) that also are able to access the search sites, so I dont think it's related to my wireless network.
The only thing I can think of is that there is something related to the fact this is an imported device that means something in the device is stopping the connections, but I cannot for the life of me think of a reason why this does not work. Especially given that it worked fine for the first month I had the device.
Anyone have any ideas?
Have you tried clearing cache and force stopping the built in browser?
Have you tried another browser, such as Opera or Firefox?
If you are rooted, have you tried to fix permissions?
I've also got the P6810 from out of the US, but this has not been an issue for me at all so I don't think it has to do with where the device was intended to be sold.
Hi thanks for the response,
Yes have tried Opera browser with the same results. Not tried firefox though, and I don't see it in the market as an available download.
I hadn't explicitly tried resetting the browser cache but have done numerous factory resets. I have just tried it now though and no difference. Though it also fails to sign into google account at browser startup.
What do you mean by fix permissions?
If you are rooted, then in an app called Rom Manager, there is a menu item to "Fix Permissions" It can sometimes fix some errors.
Another thought, assuming you have Clockworkmod Recovery flashed, then go into Recovery and wipe cache, and wipe Dalvik cache. Other than that, not sure what else you could do.
Sounds more like DNS issues, can you get to any of the search sites via IP Address?
Have you tried another wireless network to see if you can pull them on someone else network?
Try rebooting your router and modem then re-connect and see if that fixes your issues.
I know you dont think its your network, but at least you can clear it just to be sure.
Sorry for the delay in getting back with an update, but my tab went into a boot loop with Noob 2.1 and I have now reverted back to stock, also some not tab related things kept me busy for a couple of days (a new daughter), though that may actually keep me busy for a lot longer
I agree with you, it should be my router I have a Cisco E4200 router, with a Panasonic Cable modem, and roadrunner twc internet, and I have upgraded my firmware to the latest version and checked that there is no custom routing settings (I have never set any, but checked anyway). Seeing as it's more than just a single site that is an error not just google but bing, yahoo also, I don't know where/how that could get set.
When I do reboot of my router it does then work, but only for a short period of time, it's hard to work exactly what that amount of time is, but greater than a couple of hours but less that 24 hours. It is then back to "Connection to the server timed out" errors.
If people have ideas of what to check on the router then I would be interested in hearing that too, but it is just this tablet and nothing else on the network that is having the issue.
I'm stumped. I'm sort of hoping that ICS will come along and magically fix things.

[Q] [SOLVED] Apps not working with wifi but no issue through browser or 4g

So I updated to NC1 and rooted and went on with my ricing as usual but I ran into this unusual problem after about a week. Keep in mind I did not change any settings anytime close to before this happened. Apps like Facebook, Twitter, eBay, Paypal, and even the Play Store stopped working over wifi but others did such as my chanu, Craigslist, email, etc. If I go to Twitter, Facebook, eBay, etc. through Firefox everything works properly but not in the apps themselves. If I disable wifi everything works fine off of 4g.
Here are some of the things I tried in order
- rebooted device
- cleared cache of applications with issues
- booted into recovery cleared my whole cache partition
- uninstalled apps but even Play Store wont work over wifi so I had to load it up in Firefox then reinstalled
- forgot wifi network and re connected
- restarted modem
- tried with the internet at my sisters house when I was over a few days ago and still did not work. She has a note 3 and everything worked properly for her
So at this point I was willing to try anything. I rebooted my device without my SD card just for the sake of desperate troubleshooting. When I booted into it all my active logins were gone. I tried logging into my twitter and it returned an error but not an error like before just saying my network connection wasn't working properly it said something along the line of "Unknown Hosts file"
Now I am fairly familiar with the GNU/Linux system (running Arch Linux for over a year) but I cannot think of a reason why my hosts file could have been modified on my device. Even if it was modified why it would bring issues like this? Shouldn't default to my Routers DNS server then?
Do you have adblock app running?

Click to expand...
Click to collapse
It was running originally but I disabled it and changed my network setting back to not use 127.0.0.1 as a proxy and the issue was still there. I probably should have mentioned this above. Really not looking forward to it but I feel like I am going to have to flash back and start all over with my ricing/settings.
[EDIT1]Alright I just uninstalled it completely and set my proxy setting to none and still have the issue. I am going to clear my cache partition with it uninstalled and see what happens.
[EDIT2]Well what do you know it worked after I rebooting and cleared my cache partition. I think it was more of the fact of rebooting then clearing the cache. Going to go ahead a give you a thanks for reminding me about adblock, I just kind of ruled it out as an issue when I disabled it the first time. Cheers!

Can't connect to wifi that redirects to a login page

Since the MM update (stock verizon, no root) my wife's phone cannot connect to wifi networks that have a redirect to a login screen like you see in hotels and unfortunately her work network. At first I suspected an issue with chrome so I had her clear the cache for chrome which works for exactly one login. Tried different browsers and the problem persists. I sat with the phone at a restaurant last night and after 5-10 minutes of trying to connect I finally got it to work but three different browsers and cache clearing is clearly not how this is supposed to work. Is anyone else having problems like this and has anyone found a solution? I'm about ready to throw the phone away. Also for what it's worth rooting/romming not an option on this phone due to her work software.
Some additional info, on her work network when the login attempts to redirect she gets the errror: NET::ERR_CERT_COMMON_NAME_INVALID. When I was trying to get it to log in on a public network that had a redirect login page all I got was a page not available message in whichever browser I tried.
