Punkin PX5 AE0273-02A WIFI wont turn on

[Robjones]

Hello Jammy,
From your answer to question 2 you are saying that the AE0273B has a driver for the TP-Link dongle. Please tell me how to use this driver with the WN823N dongle.

Hi,
sorry that i don't know this field of knowledge well . But our engineers tells me that you can use the wifi dongle only while the build-in wifi module is broken,or there will be any conflict which lead to the wifi dongle unusable .

Hello Jammy,
Although the build-in wifi is not broken it is very weak.
Would you please ask your engineers if there is some way to disable the build-in wifi so that I can use the WN823N dongle.

Hi,smile,you have a good idea.
However ,we don't do that.Hope your kind understandings.
Get to the original issue, did you flash that firmware i gave you ? is it helpful ?

Hello Jammy,
Yes, I have flashed the firmware you recommended. Here are details of this version which is now installed:

Kernel Version: 4.4.93+
rocky@mctr930 #239
Fri Apr 27 15:16:42 CST 2018
Build number: px5-userdebug 8.0.0.OPR5 170623.007 eng hct 20180503 142728 test keys
MCU version: MTCE_KLD_V2.80_1

No, there is no improvement in the WiFi performance. It detects my FRITZ!WAN Repeater but fails to get the IP address and doesn't connect. The repeater is outside the window and 17 meters from the front of the car. My Samsung S4 receives a strong signal in the car.
Mobiles as Hotspot: It will connect to a Motorola (Moto E2) but not to my Samsung S4.

I am asking you and the Pumpkin team to find solutions to these problems.
Worried Smile: I am a member of the German Mazda forum and I would like to report that the problems with the WiFi have been fixed.

Hi,
i guess you didn't flash that firmware successfully.After you finish flashing that firmware, the date of the build number option should be 20180814 ,not 20180503 .The firmware link:

You can try to flash it again.
About the Wifi, 17 meters is really a little longer for the unit to receive wifi signal.Hope you know.You can try to place the wifi antenna near the wifi signal source.

Hello Jammy,
Thanks for your reply. I have, in fact, installed the 20180814 version. I'm sorry but the data I sent was wrong. Here are the correct details:
Model: px5
Android Version: 8.0.0
Android security patch level: October 5th, 2017
Kernel Version: 4.4.93+

If I connect the Repeater with a long cable so that it is 1.5 meters from the car's WiFi antenna it does make a connection.


The signal strength at this range is only "Ausreichend" (enough):

As you can see the S4 mobile has a very strong signal at this range. If the repeater is more than about 2 m away the AE0273B fails to get an IP-Address and no connection is possible.
The other problem is that the AE0273B will not connect to my Samsung Galaxy S4 hotspot. The hotspot works correctly with my wife's tablet.
Here are my questions:
1. Is the normal range of the WiFi only 1.5 meters?
2. Is there a reason why the AE0273B cannot connect to a Samsung S4 hotspot?

Hi,
1.as we know ,metal can shield or weaken the wifi signal .It is why the receive ability of our unit worse than your phone .Hope your kind understandings.
2.sorry that there might some imcompatibility problem between our unit and some phone . And there is no Samsung S4 for us to test. But we tested the s5,s7,and s8,and there is no problem.I suggest you try to reboot your s4.Here is an video about the s8 hot spot for your reference. https://www.youtube.com/watch?v=5UAMBnb0NKs

Hello Jammy,
Rebooting the S4 did not change anything. As I said, the S4 hotspot works with my wife's Samsung tablet. I suppose I will have to buy an S8.

The WiFi antenna is just under the plastic dashboard in the car 30 cm from the S4 mobile. Shielding is not the reason for the weak performance of the AE0273B WiFi. So it seems that the range of the WiFi is only 1 to 2 meters.
It is important for me to connect the AE0273B to my house router. Although the WiFi component of the AE0273B is not broken it is too weak to be used for this purpose. Rather than returning the unit as defect I want to connect a WiFi dongle to the USB port.

Please discuss the problem of the defective performance of the WiFi with your engineers and suggest a way of doing this.

Hi,
yes, the dashboard is plastic.However,there are many metal factors under the dashboard .
If you don't mind ,you can contact the Pumpkin customer service or write to support@autopumpkin.com to get an new wifi antenna. You can show the custmomer our communcation.
