Nameserver question #777

Closed davidhay45 closed 5 years ago

davidhay45 commented 5 years ago

I am using Alpine SD card 3.6. The redpitaya is hardwired to my pc which connects to the internet via wifi.

The gateway address on the rp is 192.168.1.1 but my wifi router ip is now 192.168.1.254 (as I changed isp). I do not have internet access from the rp. How do I change the gateway address and nameserver addresses?

What OS is running on your PC?

davidhay45 commented 5 years ago

Windows 10. The change of router address might be a red herring as I don't know if the rp had internet access before.

I think that the Internet connection sharing should be enabled on your PC as explained at the following link:

https://answers.microsoft.com/en-us/windows/forum/windows_10-networking-winpc/internet-connection-sharing-in-windows-10/f6dcac4b-5203-4c98-8cf2-dcac86d98fb9

When the Internet connection sharing is enabled, the Red Pitaya board will obtain an IP address from the DHCP server running on your PC.

Thanks for the idea but that won’t work in this set up. If I enable internet connection sharing I lose all connectivity from my pc.

I can’t even ping the W10’s ip address pc from the RP so something more basic is wrong.

This is nothing to do with RP, so many thanks for even looking at it.

How do others work with wspr in respect of internet connections? Is it possible to configure the RP with a wired connection to my pc for use with HPSDR etc and a wireless connection to my home router to allow the wspr to post the collected data to wsprnet.org?

I am not asking Pavel to tell me how to configure it just if it looks possible.

Thanks again

To finally conclude this, I tried to get the wifi and wired connections working together but without success. The problem was that I had to use a wired connection between my pc and my Redpitaya to get a reliable fast connection but that meant that the RP had no connection to the internet. My PC and RP are remote from my broadband router.

The solution was to use a wifi access point with an ethernet port to connect to an ethernet switch to which both the PC and RP are connected. It is simple but was not obvious initially.
