Secondary router connected to my network as access point has 0 upload speed
Hi all, I have the following internet connection in my main house. This works perfectly.
500/500 mbps download/upload
Main Router : Archer C64 AC1200 Gigabit
Gigabit Desktop switch (I have an Ethernet cable from my main router (LAN port) to the desktop switch and from the desktop switch I have 1 Ethernet cable that goes to my TV (10m cable) and another Ethernet cable that goes to my outbuilding (50-60m cable)
In my outbuilding I have a TP link Archer C20.
I have set it up as and access point. The Ethernet cable from the desktop switch in the main house connects into the WAN port on the Archer C20.
Scenario 1 (Archer C20 not connected)
If I plug the Ethernet cable in the outbuilding directly into my laptop I get a download and upload speed of around 80mbps. I am not sure why it is so low. When using my laptop in the main house with Ethernet cable I get speeds in excess of 400mbps. Could this be because the cable is too long ?
In the outbuilding, when using the Archer C20 as an access point (Ethernet cable from desktop switch in main house plugged into WAN port in Archer C20 in the out building. I get 80mbps download speed but upload speed is 0 and can barely use the internet.
At first I thought that this could be a cable fault so I bought a cable tester. All lights light up in the correct sequence. The light number 2 seems to be slightly dimmer than the rest.
So I am at the stage now where I either need to replace the Archer C20 modem or install a new Ethernet cable from the main house to the outbuilding or both.
Any advice will be helpful
