Hi Benny, someone posted some information about an incompatibility with the
Blade and the Netgear DG834G v5 router, this seems specific to this router so
I’m not sure if your developers can do anything if they don’t have one of them?
Are there any logs I can ask this person for to provide extra information for
your developers?
Regards
Rob
Could this please be fed back to ZTE as a specific reproducible wifi anomaly?
On disconnecting (whether because of sleep or manual disconnect) from the
Netgear DG834G v5 the SF will not reconnect successfully unless (until) the
router is rebooted.
Phone wifi off/on is not sufficient to reconnect to that router.
The problem seems to happen on every disconnect from that router.
Its not about DG834G v5 compatibility.
Its about the reconnection activity of the SF/Blade not working properly.
The DG834G v5 gives a solid demonstration of where the problems lie. (The v5 is
important. I know the v3 behaves differently.)
If the cause of this were to be determined, it might incidentally be very
helpful to the many many others suffering occasional failures to reconnect.
This is a solid problem in the same area and might well shed some light on
other reconnection difficulties.

Hello Rob.
That's comes from our developers. for you issue about the " Blade Sleeping "
In most cases it's not a hardware limitation. It's about power consumption.
Power consumption is a very important aspect of user experience. If you keep
everything working when the phone goes to sleep, you will definitely suffer a
battery drain. I think Android has provides you UI interfaces to control the
behaviour of some hardware modules when the phone goes to sleep (if it makes
sense to have that module on during sleeping). For example, you can have the
bluetooth module working when the phone sleeps. But surely it will incur a
power consumption penalty. It's up to you. For many other haredware modules, We
don't see any reason to have them on when the phone is suspended. For example,
the light sensor. What's the point of having light sensor working when the
phone sleeps? For these modules, users don't have any chance to control their
sleep behaviour. So technically you can do anything you like, surely at the
risk of a shorter battery life.
When USB cable is connected, the phone doesn't really sleep. Only the LCD and
some other modules are turned off. Generally the LCD(including the backlight
module) consumes most current on the phone. It's not necessary to go to deeper
sleep other than turning off LCD because after turning off LCD, the USB cable
supplies far more current than the amount that the phone consumes. There is no
need to perform a full sleep. It might take a little bit more time to have the
phone fully charged than in a full sleep. But it's not noticable.
WIFI module is special. The chip has a limitation. It must be totally powered
off and brought up again when the phone wakes up.
Concerning the key issue you may have some misunderstanding. ZTE handsets
highly conform with Android conventions. What keys can wake up the phone and
what keys can turn on the screen? They are different things. You must first
wake up the phone and then turn on the screen. 7k_handset.kl is only
responsible for defining keys that can turn on the screen. You edit that file
but it takes no effect because these keys you add are not even eligible to wake
up the phone. Keys that can wake up the phone are defined by the manufacturer.
Users are not encouraged to change it.
Best regards.

Hi, I am still being asked the source to the wifi driver, you mentioned that
you couldn't provide it because it was given to you by a 3rd party, can you
please provide contact details for the 3rd party so that I can ask them about
it? Also, can you check the license that came with that source just in case it
is open source in which case you should be ok to release it?
Thanks
Rob
