Hi all .
Am having issues after updating my rs2 to the latest dev firm ware.
1- I can’t connect to a known wifi network yet it’s on.
2- I can’t connect to NTRIP neither can I download a source list .
Here is a simple system report.

Any help is appreciated

Hi Matt,

Let me ask some of the questions below.

Do I understand correctly that you were able to connect to this network prior to the update? Please note that Reach receivers are working with the 2.4 GHz networks only.

May I ask you to specify if you provide the unit with the internet via the cellular modem? Is there any indication of the error that prevents the unit from connecting to the NTRIP service?

mattfrederick6 · July 20, 2020, 7:22am

Hi Polina that’s the screen shot of the network am trying to connect to.
Everything worked perfectly before the update
And yes the rs2 has full internet access because it even shares during hotspot mode.

Hope this video can help

Hi Matt,

Does your receiver able to connect to a different Wi-Fi network?

Also, it looks like your receiver repeatedly losing connection with the NTRIP server. It might be a connection issue over a cellular network.

May I ask you to download a full system report and send it to support@emlid.com so that we can examine it?

mattfrederick6 · July 20, 2020, 3:18pm

Hi I have sent the full system report to emlid support.
After resetting the rs2 I have been able to connect to NTRIP.

But the issue of wifi still persists.
Am yet to check the reliability of this fix against known controls .

mattfrederick6 · July 24, 2020, 3:01am

I have reflashed firm ware but it has just worsened the situation coz I can’t get past this

As it neither connects nor sees wifi networks.
It’s too disturbing.

polina.buriak · July 24, 2020, 7:53am

Hi Matt,

May I ask you to specify if you tried different Wi-Fi networks to update? Have you tried the hotspot of your smartphone?

Would it be possible to describe the LED status of the receiver while you’re trying to connect it to the Wi-Fi network? Does the LED network start blinking rapidly in search of the network?

mattfrederick6 · July 24, 2020, 10:21am

Hello Polina .
It’s the smart phone am using .
The machine blinks blue rapidly trying to connect to the network but after it fails and returns to solid white ( hotspot mode)

polina.buriak · July 24, 2020, 4:14pm

Matt,

Just to be sure, have you double-checked the password and the SSID? Have you tried connecting to your local Wi-Fi or other device’s hotspot?

mattfrederick6 · July 24, 2020, 6:09pm

Hi .
Yeah the WiFi is open. I will try to check with other wifi network and see if it can work. thanks

polina.buriak · July 28, 2020, 6:53am

Matt,

Have you had a chance to check another Wi-Fi network? Does the issue still persist?

FJDT · July 28, 2020, 7:21am

Hi Polina - regarding mattfrederick6’s wifi issues this seems identical to my posted problem after upgrade. I aslo tried flashing one unit and have the same further problem getting past the non working hotspot. Thanks.

mattfrederick6 · July 28, 2020, 12:40pm

Hi Polina
I have tried more wifi networks but some work others don’t so it’s a gamble.
I was waiting for @mikhail.goryachev mikhail to give me the results after examining the full system report

mattfrederick6 · August 3, 2020, 3:42am

Hi @mikhail.goryachev @polina.buriak have you found out anything yet regarding the issue?

polina.buriak · August 7, 2020, 2:49pm

Hi Matt,

Sorry for the delayed reply!

Please contact us on support@emlid.com with the following information:

order date and number
Reach RS2 Serial Number (you can find it by scanning the QR code under the SIM card slot)
your shipping address

mattfrederick6 · August 7, 2020, 3:05pm

Hi I have sent it .
But please let me know quick because am having an upcoming project where I want to use this machine.

polina.buriak · August 14, 2020, 7:48pm

Hey there,

Just wanted to say that we’ll be checking what could be the issue with the unit ourselves.
