This feature is working fine on an
  Unagi
    1.3.0.0-prerelease
    27.0a1
    2013-10-17-04
    unagi/1.3.0/default
    <no git commit info>

and it does not work on an
  Unagi
    1.3.0.0-prerelease
    28.0a1
    2013-11-27-10
    default
    2013-11-20 10:09:26 d2b07c09

Note that none of the phones have a sim card, and the USB tethering can be enabled on the latest.

The use case is to create a local network with no internet connectivity which I use to make multiple computer/phones interact on the same network.

QA Wanted - can we see if this reproduces on 1.2?

Comment 2

[Chuck Lee [:chucklee, Triggered by NI, Review, and Feedback requests]]

I think it's because there's a rule in gaia limits "wifi hotspot cannot be enabled without sim"
https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/internet_sharing.js#L106

There's always discussion about should hotspot can be enabled or not without cellular data connection.
The current behavior is based on partner's request, from bug 868902.

So if we allow enable hotspot without cellular data, there will be another bug says we shouldn't.
I like to have someone, but don't know who, to make a final call, and settle down the issue once forever.

This does not repro on 1.2. Both devices used do not have SIM cards and no Wi-Fi hotspot can be found.

"This does repro"

Comment 5

[Jason Smith [:jsmith]]

Does this reproduce on 1.1?

Comment 6

[gbennett]

This repros on 1.1, but not in the same way as 1.2. 1.2 the wifi hotspot does not show up when searching for a wifi connection. 1.1 other devices can see and connect to the wifi hotspot, but are unable to surf the web or use the connection for online purposes.

You mean this cannot be reproduced on 1.1? This is expected that you cannot browse the Web if you do not have any Sim card on the phone which is hosting the Wifi Hotspot, and unless you mean that the phone which connects to the wifi hotspot cannot browse the web even if it has a sim card? In which case this another issue.

Ah if that is the expected then everything is working fine for 1.1 as I did not have a SIM card in the phone, sorry for any confusion.

Comment 9

[Peter Dolanjski [:pdol]]

I think this would be classified under WiFi, but feel free to re-categorize if I'm wrong.

Comment 10

[Vincent Chang[:vchang][changyihsin]]

Per comment 2, I think this bug should be marked as invalid because it is by design.

[Michael Vines [:m1] [:evilmachines]]

Seems like the behavior should be customizable by a preference, as I don't think there's uniform agreement on this across OSes and operators.   But as the current behavior is WAD, adding such a preference or flipping the default is not blocking for us.

Not a blocker per this above comment.

Comment 16

[Ken Chang[:kenkai]]

According comment 2, 10, and 14, It is by design and not a real issue.

Comment 17

[Tarek Ziadé (:tarek)]

I am confused with the output of this issue. I understand that this feature is not a blocker for a given release, but I don't understand if we're planning to have it one day or not.

Comment 18

[Tarek Ziadé (:tarek)]

I don't understand why you are marking this bug as wontfix - what about the case where I do have a sim card ? does the wifi hotspot works in this case ?

Why you need this? May you please provide a user scenario?
We can base on your scenario to think if we need to add this feature in firefox os.
But now this bug is different from current design of firefox OS. That is why I mark it wontfix.

to create a wifi hotspot ?

User creates a wifi hotspot...

One question you have not answered, is if it will work with a sim card ? does the wifi hotspot still works in this case ?

> We can base on your scenario to think if we need to add this feature in firefox os.
But now this bug is different from current design of firefox OS. That is why I mark it wontfix.

I don't understand these two sentences. If it's decided that the wifi hotspot won't work when the phone
does not have a sim card - that's fine and that was explained.

I would just like to know if this feature will be present when we do have a sim card. If not there is probably a good reason and I'd love to know what is that reason. Please don't answer with more questions ;)

Comment 21

[Ken Chang[:kenkai]]

Comment 2 has answered your question...:-)

Comment 22

[Tarek Ziadé (:tarek)]

No it's not as far as I see. Please answer to this question by yes or no:

will wifi hotspot be supported on a phone that contains a sim card ?

After testing on a recent build, it seems to be working if there is a sim card in the phone which serve as hotspot.  I don't know if phones connected on one device can communicate between each others, as it was before, or if this is only used for tunneling.

Thanks for the testing Nicolas
