What do you mean by extended network? Does this Archer C20 work as an extender or Access Point? How does it connect to the main router? You may refer to the previous suggestions provided by Solla-topee.

I configured the archer c20 v5 as range extender. The configuration was completed with no issues. When I try to access the extended net I created my devices connect to the net "extended net" , but this network is not connected to Internet. 

 

If I go to tplink net configuration page, in "network" it keeeps me showing that there is no conection to Internet, which is false, cause if I connect to the main network, (the one I want to extend) I can navigate normally.

 

The net sometimes connect, but becomes intermitent and too slow and block the speed of the main one. 

 

Also I made the speed test for the main network and gave me 58 MBps , when I turn on the tp link drops the main one to 3 MBps. 

 

I want to know what is happening, because I have another archer c20 and this doesnt Happen with thah one.

What is the distance between the Archer C20 and your main router? Are they connected via 2.4G or 5G? How about the signal at the location of the C20 when searching for the main Wi-Fi? If the signal from the main Wi-Fi is poor, you will not have a stable connection between the C20 and the main.

 

BTW, what is the model number of the main router? You may also try to modify its wireless settings, such as wireless channel and channel width, then reconnect the C20 to that.

I put The archer c20 near the router the signal is more than 90% and the problem is the same. 

 

The módem of the main network is an arris tg2482A provided by the Internet company. 

 

As I said., I have another c20 and this works well. I Just configure it and it works as I need. But this archer c20w I configure it but it doesnt work. Fotñr the devices The extended network its ustable, and when the c20 is activated the speed of the entre network drops. Evrn the speed of the principal network...

the firmware of the one that doesnt work is Hardware Version:Archer C20 v5 0000000 Firmware Version:3.16.0 0.9.1 v6038.0 Build 190625 Rel.62407n and for the one that works correctly is: hardware V5 0.9.1 4.16 v0001.0 Build 190103 Rel.45825n(4553)

Thats how it looks my configuration window.  I can navigate on the net in all my devices connected to the router, so the connection to internet is OK, but when its the archer On, it blocks the connection, and i cannot navigate .

@Oer4000 

 

If that is the case as you described, you can try to downgrade the firmware of the one that is currently not working to the 0.9.1 4.16 v0001.0 Build 190103 Rel.45825n(4553), then confirm how it goes.

 

If that still doesn't help at all, please contact the local tech support to confirm if there is a hardware issue with the specific unit:
