Hello,
I equipped my CS3+ with a TP-Link Nano router configured into the Client mode.
Now from my CS3+, I can connect to the internet for updates.
But, I can't get my computer (wi-fi PC under Windows 10) to connect to the CS3+ through the Wi-Fi network...
On the PC side I have a IP address attributed by the DHCP server in the range of : 172.16.3.44
On the CS3+ side the IP address given by the DHCP server is : 192.168.0.100
So, of course, with these 2 different ranges, it cannot communicate.
Then I tried to give to the CS3+ a manual address like : 172.16.3.54 and in the CAN section I input 172.16.3.44 in Broadcast mode.
But this does not work either...
To verify the connection, I try to access the CS3+ via my PC browser using the CS3+ address (172.16.3.54).
Any help would be highly appreciated...

PS: when changing IP address on the CS3+, should I restart it or should I choose a "hard" boot by switching it OFF and then restarting it ?
Is it important the order in which I start my CS3+ and my PC ?

Most Routers have a Setting/Feature called Wireless Isolation (I think Tp-link calls it AP Isolation).
It's often enabled by default and prevents a Device from interacting with other Devices on the Network to increase security.

Could you check if this Setting is disabled on your Router?

Thank you for your answer, but after looking at my TP-Link and at its software, I can't find any wireless isolation...

If I understand correctly, you have an actual Router/AP (The device between your Network and the Internet). You then have the Client-Mode Nano connected to the WLAN and finally the Nano connects to the CS3 using a Cable? The setting should be on the actual Router/AP (not the one in Client mode), for TP-Link it's in Wireless>Wireless Advanced>Enable AP Isolation.
If your Router actually has no option for Wireless Isolation or it is in fact disabled, it would be very ideal if you could if you could try to connect other devices than the cs3 with each other.

In fact, it already happened that the CS3+ got connected to the PC when the DHCP server attributed automatically to the CS3+ an address in the right range as the PC (at the time it was 172.16.3.100).
So, the hardware configuration seems to be ok.
Now, since i switch back ON my CS3+, the DHCP server keep on attributing it an address like 192.168.0.100 which is not in the right range to communicate with the PC...
This is why I tried to "force" the address manually on the CS3+, but the PC still cannot see the CS3+...

I think your PC address is the odd one out, normally within a home network the addresses will start with 192.168.x.x as you are seeing on tyor cs3+.

Is your PC set up for DHCP? it really should be, then the router will assign it an address in the correct address range.

My PC is set for DHCP.
Should I try to disable DHCP for the PC and use a manually chosen address in the range of 192.168.xxx.xxx ?

I think I would want to see a sketch of how you have everything connected, as I don't think it is connecting how and where you think it is.

If you disable DHCP on the PC I think it will stop connecting to the outside world. I also suspect you cs3 is connecting through someone elses router as it is not showing the same IP address range as the PC.

In addition to the 192.186.xx.xx range reserved for private networks the ranges 172.16.xx.xx to 172.31.xx.xx and 10.xx.xx.xx are also reserved for private networks and are perfectly valid addresses.
But this still means that there are two devices giving out the IP addresses (DHCP Servers), the router uses the 172.16.0.0/12 range and the Client-mode Router uses the 192.168.0.0/16 range.
If there is a list of devices on the network does the CS3 appear on it or just the Client-mode Router?

Do you know what the IP of the CS3 was when the PC was able to contact it? If I understand correctly, the CS3 can also still conect to the Internet?
And I suppose this issue arose without changing any settings?

sounds like you have to get the nano router to use a subnet of 172.16.x.x or have your main router use a subnet of 192.168.x.x

Hi FHP2

Sorry I’m not as good as all you guys are but I do have my iphone running with my CS3+ and I believe there is a download for a android phone. Also I have a CS2 which runs on my PC MAC OS. Haven’t tried it yet on the CS3+ If I can be of any help?

Thank you for your help.
I finally found the solution.
In the software settings of the TP-Link Nano, before setting the mode to "Client", I found a way to change the default address range that was set to 192.168.0.100.
There is a menu item named "Lan" under which you can change this default setting. I set it to 172.16.3.100.
Then I set the TP-Link in Client mode, then rebooted it. All this was done through my computer.
Then I connected the TP-Link to my CS3+ and "hard rebooted" it.
Now It works and my computer is capable to connect to the CS3+...!!
Again thank you to all of you for your help !
Francois.

I'd expect you need to be on the same subnet with the PC as the CS.
Your CS is on the private 192.168.x.y subnet.
Your PC is on the 172.16.x.y subnet
Those two sub-networks are not connected by routing standards.
I'd configure the TCP/IP connection on the CS to use the same subnet as the computer (192.168.x.y).
If you are using two routers (as I think you are) then you also need to configure them to work together to bridge traffic I think.
