Android + ipv6 = trouble

HairyMcbiker — Mon, 30 Dec 2013 12:29:44 GMT

Having severe issues with my Android tablets trying to get them to download from Play store.
It says there are updates waiting but can't download them.
Anybody else having same issues?

Android phone is OK. Have had a number of updates since being on IPv6.

Well just tried to login using my "real" user id, and failed. Router rebooted and is logged in as the ipv6test user but as ipv4 ONLY. Updates are fine now. Will go back through setting it up as ipv6 again and see if it still fails.

I've not seen any problems myself. Do you have IPv6 working on Android for other aspects eg web browsing etc?
You could try installing an app from the online Play store as this 'push' action can sometimes help resolve certain client-side 'pull' issues.
Edit: Ah, I see you're sorted now.

Nope the tablet is ipv4 only.
Logged in as my normal user and all apps updated fine. I was trying to PUSH an app when I noticed the updates were still trying to download from YESTERDAY, tablet on overnight.
Will reload my ipv6 config again and try to push another app.

OK ipv6 config reloaded. Ping 6 works from pc

But a push install FAILS on the tablet, have dropped and reconnected the wifi connection, the download is just sitting at 0 (zero) % done.

It's the IPv6 on the Android that you need to be concerned about. Try something like Network Stats II to verify IPv4/6 addresses are being assigned (and/or online test sites).

Re: Android + ipv6 = trouble

HairyMcbiker — Mon, 30 Dec 2013 14:08:50 GMT

But since I can't get stuff to install in v6 mode...
EDIT:
OK loaded v4 config, pushed IPCONFIG to tablet and reloaded the v6 config.
The tablet HAS an ip v6 address, and I can ping it from the pc using its v6 address.
Test-ipv6.com shows 10/10 on the tablet.

Re: Android + ipv6 = trouble

HairyMcbiker — Mon, 30 Dec 2013 18:40:16 GMT

Further testing shows the issue is ONLY with play updates/installs.
I can install from Amzon or onemobile fine with ipv6 enabled.
Installs (either from the market app or pushed) just sit there downloading at 0%.

It usually works ok for me using a Tunnel-broker tunnel perhaps a routing issue between plusnet and google?
Is it possible to get a tracert posted?
Don't think android exposes options for disabling IPv6

Re: Android + ipv6 = trouble

HairyMcbiker — Tue, 31 Dec 2013 11:16:46 GMT

Strange thing is it works on my Phone (LG-610) but not on 2 generic Android tablets.
I tried just now pushing the phone copy of Phonesky (the market) on to a tablet and clearing the cache etc. Still just sits there.
Doing a google on it, only shows issues with one phone and it works if you go via a proxy. So not sure what to try next. Anybody know of a free proxy I can try?

For those who need it:
To disable ipv6 in android
echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
I added it to a startup script.

It's a shame you never got to the bottom of this one.

Re: Android + ipv6 = trouble

HairyMcbiker — Sat, 05 Apr 2014 14:48:40 GMT

I really couldn't figure out what was wrong.
Using dns tools I had an ipv6 address fine, I could ping back and forward but play store just refused to download apps using ipv6, Amazon/one mobile were fine.
In the end I just disabled it, life’s too short.

Did you look at lowering the MTU to see if that made any difference?

Re: Android + ipv6 = trouble

paulmh5 — Sat, 05 Apr 2014 14:58:45 GMT

I've never had any issues with my Nexus 5 and 7 that I've been able to put down to IPv6 anyway.
I have had them get stuck installing apps buts its cleared up after a day or so. I'd be interested to know where its trying to download the app from.

Re: Android + ipv6 = trouble

HairyMcbiker — Sat, 05 Apr 2014 15:26:53 GMT

I haven't played with MTU's on the droid's as a simple disable fixes it.
I don't know and without a wireshark of the wifi I will not be tracing it, as I said life's to short.
It maybe different on "branded" devices, but all mine are cheap China tablets that work apart from this ipv6 issue with play store. As I say I can surf the store and it shows in the taskbar as downloading then just sits there. Disable v6 and off it goes, so it is not trying to download from an v6 address. Same thing happens if I push it from the pc via the store, it appears on the tb and just halts until v6 is off. (I need to stop and restart the download to get it to download though)

Re: Android + ipv6 = trouble

MJN — Sat, 05 Apr 2014 15:30:43 GMT

If you do ever get chance to resurrect the troubleshooting you could try and influence the MTU setting on your tablets by modifying the the MTU of the link in the RA messages sent by the router:

=>:ip rt6advd ifdetach intf LocalNetwork
=>:ip rt6advd ifconfig intf LocalNetwork linkmtu 1492
=>:ip rt6advd ifattach intf LocalNetwork

Re: Android + ipv6 = trouble

AndyH — Sat, 05 Apr 2014 15:41:59 GMT

When I tried that on the TG582N, I had to set the MTU to 1400 - for some reason anything above that gave an error.
