Couldn't set tty to PPP discipline: Invalid argument

seems the success very close but i need your help

[Josh]

The problem may be annother missing module ...

I just learned that Samsung users might need the "ppp_async" module as well.

Grab the latest package for GT-P3110 from the sticky thread. You will have to load the "ppp_async.ko" module manually until the next PPP Widget update.

[lecureuil38]

you are right!
insmod ppp_async.ko and ok: i was conected to mockwifi!

[Josh]

Great!

Thanks for the confirmation.

[lecureuil38]

hi josh,
since i update my tab to Jelly Bean (4.1.1) i received 'port wasn't found'
i think i need a new module for my tab 2 7.0 (GT-P3310)
the kernel number is 3.0.31-523998.
thank's by advance

[Josh]

Hmm, I see some number tweaks in your post, like "GT-P3310" ...

I'd suggest you double check that kernel name. It has to be correct to the letter.
Does it not contain a "-user" appendix, for instance?

I googled for the name you gave, and there are no results at all which I find implausible.

[lecureuil38]

maybe, i have updated my tab with odin and a firwmware download from samMobile (P3110XXCLK5 ).
Root with CCF-Auto-Root-espressowifi-gtp3110 from xda; CWM version is 6.0.1.1.
i check the kernel number again : 3.0.31-523998

[Josh]

Unfortunately, I can't provide kernel modules for custom ROMs.

Please ask the developers who made the kernel you are using.

[lecureuil38]

this is not a custom rom: it provide samsung! ( sammobile firmware)

[Josh]

O.K., I have seen the release. It's just a very fresh one, so the kernel name is not widely known yet.

There is annother problem though: the source code has not been released so far.
The latest release on http://opensource.samsung.com/ is still ICS (4.0.x) ...

[lecureuil38]

ok, i need to be patient
i take a look on your link and i see te gt-p5110 is realised to jb, so wait and see!

[lecureuil38]

i see it today on xda forum :
the ota update jb for gt-p5110 share the same kernel number of my gt-p3110 : 3.0.31 -523998 and is available for dl on sammobile, may be Josh, you can extract orcompil module for both gt-p5/3110?

This is log for Aero2 Polish free internet provider. My tablet is Samsung P3100 (I know it is 3G tablet but many of my friends have P3110 and I want to help them to get external modem working testing it on my tablet).

I compiled all needed modules for stock kernel: 3.0.8-1060937, I load ppp_async.ko manually but as you can see it looks provider wants some kind of authentication.
For this provider only APN name is needed 'darmowy' and no user/password has to be entered.
Thank you in advance for your time

[Josh]

Even if no user/password is required by the provider, try to enter anything in these fields, just two random letters or so.

I'm wondering why pppwidget tries to send:

Code: Select all

sent [IPCP ConfReq id=0x1 <addr 0.0.0.0> <ms-dns1 0.0.0.0> <ms-dns3 0.0.0.0>]

IP address should be received from DHCP server.
