Hello all,
I have a boxchip A10 based android 2.3.4 device - the Yinlips YDPG18.
I''ve setup the wifi connection (as this is the only method of communication) and can access most sites without any problem.
However, it seems like there is a problem with certain google servers:
- I can use "google.com", but any searches via "google.com/m" fail after the first try (and have to clear the data for the browser to make it work again)
- while trying to setup my google account I get the "Cant' establish a reliable data connection to the server" message, ADB reporting a "java.net.SocketTimeoutException: Read timed out" error.
- some applications seem to have trouble accessing certain content, like Amazon Appstore (the login works, but does not display any items)
Here are some of the things I've tried so far with absolutely no luck:
- reflashing and reformatiing the device
- changing the DNS servers, wifi router and internet provider (my android tablet work just fine on the same setup)
- upgrading the Services Framework and browser apps
- changing the device name in build.prop
- messing around with various settings in accounts.db, googlesettings.db and settings.db
My best guess is that somehow the device gets selectively blocked based on some criteria, but I can't really explain how.
Any help would be highly appreciated, as I'm starting to run out of ideas...
Thank you!
Sorry to bother you with this, but I could not find anything remotely similar discussed anywhere.
My Sony Xperia S sometimes loses the default route for internet access.
The symptoms are:
- I can access all the local computers on the network just fine
- external web sites do not work
What I see when checking on the command line via "ip route" is
Code:
192.168.0.1 dev wlan0 scope link
Luckily my phone is rooted so I can just "su" and then
Code:
ip route add default via 192.168.0.1 dev wlan0
Afterwards, the internet access is working again for some time.
WiFI settings are set to a static IP address 192.168.0.11 with the default gateway configured to 192.168.0.1.
Why is the device losing the default route?
How can I prevent this?
Is there a file somewhere that needs to be changed for the route to persist?
I did not have this problem with Gingerbread. It started after upgrading to ICS.
Laptops work fine on the same WiFi network and do not lose internet access.
<Princess Leia voice>Please, XDAdevelopers, you are my last hope.</Princess Leia voice>
I'm having the same issue with my S after rooting/updating to ICE WIFI is still connected and LAN works ok, but no internet access turning WIFI on and off is the only way i can get it working
hope the is a fix
Sounds similar to an issue I was having as well. Actually, I was having it prior to the ICS update as well, i.e. with GB.
The only way I found to reliably get internet access on my SXS was to reconfigure my router to use DHCP, which was somewhat annoying. Had to reconfigure all my network nodes as well, of course, which were using static IPs.
Static IP had never been an issue with my old HTC Desire running GB (and earlier versions) or my ASUS Transformer with Honeycomb and ICS. Definitely seems to be SXS-specific.
I do not want to work through the hassle of changing the settings in my more than 20 devices on the network just to get this one working reliably.
Is there no other way than to switch on DHCP?
I tried DHCP and it didn't work for me.
and just because use run DHCP doesn't mean you would have to change all you devices, you can leave then as static.
I've been having the same issue on mine - did it occasionally on Gingerbread but has been noticeably worse on ICS - turning WiFi off then on again cures it 60% of the time, three off/on combos sorts it's 95% of the time
I noticed this week while visiting my parents that it worked first time every time, of course this is a DHCP setup!
I'll be setting my home router to give a fixed IP to my phone tonight - but that doesn't help at work where I need to override the DNS settings (don't care if the IP is dynamic or not - just need to use different DNS servers*!).
* And yup I have permission to do so - Facebook and a few others are crudely blocked using DNS, but authorised people are allowed access (basically so we can delete nasty posts) and this is over-ridden using static IP - gets annoying that Facebook trashes my authorisation when it falls in this blackhole.
Curious if anyone else has experienced this issue? Since upgrading to android 4.3 roms, I have not been able to use my home proxy correctly. Connections to my proxy have been successful, in that, android still reports internet connection, however when using apps (that are blocked on my work wifi) are showing no connection. 4.2.2 roms all work fine.
The app I'm using is ProxyDroid however I also tried setting the proxy in native settings with the same result. Is there a change in the implementation of proxy services since 4.2 roms? Thanks in advance.
Maybe it will work with Drony or SandroProxy

Drony, is the wrong kind of proxy (server not client). SandroProxy isn't working either though (I mean in 4.3), however its very difficult to use; It's possible I screwed up setting it up (still was showing 'listening 127.0.0.1').
Drony is subset of SandroProxy so it acts the same way. You probably need just Drony.

Interesting implementation. Perhaps I will try it again. I'm curious is there a widget for quickly connecting/disconnecting from proxy's? Unfortunately running through my house its not a very fast connection (one of the biggest reasons I went with ProxyDroid, there is a quick connect/disconnect).
Drony will go on if active wifi has proxy set on localhost 8020.
It goes off if wifi goes down.
What can you miss with Drony is that not all apps will work.
For example WhatsApp do not respect androiod os proxy settings.
To have all working you need rooted phone and SandroProxy.
It install his own local copy of iptables to redirect all traffic.
But has more features and it is harder to set up as you find out .
It is more a developer tool than a plain proxy.
There is some wizard to help you out.
And acts the same way as Drony listening if active wifi has proxy set that points to it.

Hi all
I've setup VPn tunnels to my office on my S9+. I've setup a PPTP from the built in client and IPsec and SSL from the Fortinet Client and none of them are working.
I'm sure that authentications are correct as I use same settings on my laptop running windows 10 and on a iPhone 7 plus.
Anyone with the same problem?
This might not help you exactly but there seems to be an issue with the stock ROM and VPNs. Adguard, which blocks ads via VPN, was also having the same issue and the devs have reported it to Samsung from what I understand. The fix will probably come during a later update since VPN issues are a bigndeal, especially for people who need to use their devices in a corporate environment.
My VPNs include one PPTP and one IPSec/PSK, and they both connect without issues on four different Verizon S9+ phones.

Same here, PPTP not working on my s9+. But IPSec/PSK working (slow speed)
Hi
same here . It's little different for me
PPTP work with S9 but in hotspot, i can't connect to PPTP VPN on my laptop with wifi of S9 !
There is a really problem with PPTP ...
I opened ticket here : https://forum.xda-developers.com/galaxy-s9/help/hotspot-vpn-pptp-issue-t3765773 !
New firmware for s9+ and s9
I m waiting new file for my s9.
Bug of vpn pptp is solved ?
not solved with last firmware ...

Hola
I just wanted to give you a heads up that Adguard dev's have figured out a temporary workaround to make the their VPN ad blocking features stick. You'll need to check their forums for the actual setting (or use their nightly release which has the setting enabled by default). I have this setting enabled and now I am able to browse ad free for the most part without issues.
I've just update the phone and it's now working yet. Besides that the problem is even worst because I can't even connect VPNs on my laptop if using the phone as hotspot.
I've reported to Samsung and I'm waiting for a call and a remote assistence but if I can get a fix in a few days the phone will be returned because this is a big issue for my work.

I used this functionality fairly frequently with my (Verizon) S8+.
I've just completed about an hour of testing with my (Verizon) S9+.
I tried the USB tether, the Bluetooth tether, and the Hotspot networking on the phone. In each case I established a network connection to the public Internet without issue.
The VPN connections from my Windows 10 system, however - using that S9+ connection - all fail now with one exception.
The PPTP, L2TP/PSK and IKEv2 connections (that all work[ed] with my S8+) will not connect using my S9+.
The one exception is the Microsoft-specific SSTP variant, which tunnels over port-443. That one will connect with the S9+ in all three networking scenarios - USB, bluetooth and Hotspot WiFi.
This seems to indicate that the new phone does not pass TCP port 1723 and/or GRE 47 (PPTP) and UDP ports 500 and/or 4500 (L2TP and IKEv2) through it's network tethering and the WiFi connections.
Bummer.
At least I can still use SSTP to get to my server resources - which is 90% of my VPN needs anyway - but the other connections are dead now.
Connections FROM the phone, using it's built-in PPTP and L2TP profiles to host networks, continue to work properly on the S9+ -- as they did on the S8+.

That is the Snapdragon version? Does it have a special ROM from Verizon or is the stock Samsung?
Maybe that is the difference

Stock Verizon (SD845 8.0) S9+ compared with a stock Verizon (SD835 7.0) S8+. I suppose the difference might be explained by going from Android 7 to Android 8, but I have no way of testing that hypothesis at this time.
(The last phone I modified was a 2013 Motorola RAZR. I've subsequently switched to using my phones as phones, rather than as a hobby. )
If someone has a different experience with employing a networked platform's VPN while using a similar phone in a tethered or hotspot configuration, it would interesting to know.
My own successes with the phone's built-in VPN (PPTP and L2TP) - as separate from the scenario described above -
apparently differ from those of others in this thread for reasons I cannot explain.
I'm in the same boat - a new S9 and can't connect to my work VPN when using the phone as a hotspot. It works fine on S8 and Iphones. Does anyone know how to fix this? This is a critical issue for me as I work remotely quite a bit.

I think there is no fix yet. I had someone from Samsung support connected to my S9 last Tuesday and they could not find anything so they escalated the problem inside Samsung but until now no further news.
S9+ work with IPSEC!
My Samsung S9+ work with IPSEC - tested on Andoid version 8.0.0..

What CPU does it have? Is it unlocked or from what network/provider is it?

CPU - Exynos 9810 - 2,7 GHz, its on Croatian network - T-Com ( T-mobile ) - locked.
New update in germany : G960FXXS1ARD1
Maybe a good patch ...
My S9 unlocked (SD) can connect to my L2TP/Ipsec VPN but disconnects within a minute or so (even if the connection is under constant use.) I have another Anrdoid 7 device (and a Windows 10 laptop) that has no problem with the same VPN/router/WiFi combination and can stay connected for hours. I don't know how to escalate this with Samsung in a way where they just don't blame my other hardware.

Hello guys,
I have had one specific problem for literally years now and I could never find a solution.
Say I've got a Galaxy S20 and I won't root it. Leaves me with three options to block ads:
- use Firefox and uBlock origin
- set dns.adguard.com as custom DNS
- use Blokada, DNS66 or any other VPN-based adblocker
The problem with the latter two: Chrome will randomly stop functioning whenever I am connected to any wifi network.
It will just stop loading random sites, not show all pictures in Google Image search, not show anything anymore when you click back and forward or just stop loading anything at all.
Go to mobile connection, it immediately works. Disable the DNS/VPN blocker, it immediately works.
Reconnect wifi, it will work again for a while. Can be two days, can be ten minutes. It's completely random.
I am not able to figure out ANY reason why this is happening.
I know Chrome has its own DNS resolver and you should disable it when using DNS based blocking methods (disable async dns resolver and clear dns cache), and while this fixes the problem that not all ads are blocked in a reliable way, it doesn't fix the wifi connection loss.
Using DNS or VPN based blockers only cause problems in Chrome, no other app.
I know I could just switch browsers, its just that I use Chrome on desktop as well and like the synced bookmarks.
Does anyone have any idea why using a VPN/DNS based adblocker would cause Chrome to specifically stop working randomly only in a wifi network, but not via mobile?
I have had this issue over several devices and Android versions for years now and I can't figure it out.
Curious if any of you can help.
