Model : Archer C2 750

Hardware Version : Archer C20 v1

Firmware Version : 0.9.1 2.1 v0044.0 Build 151120 Rel.35051n

ISP : TEO

When connecting directly to fiber internet box i get 300+ Mbps.

Ethernet status in windows says Speed: 1 Gbps.





When connecting through Archer C20 (via CAT5 or CAT5e) cable, i get 100 Mbps.

Ethernet status in windows says Speed: 100 Mbps.




I've just upgraded router to latest firmware, didn't help.
Used two different cables: 1m long CAT5 and 15m long CAT5e. Same results.
btw ethernet porth (in the back of the case) gives different colours: red when 1 Gbps and green when 100 Mbps.

During quick setup of the router i chose (at WAN Connection type) - Auto-Detect.

How can i fix this? Or is it a defective unit?

Your unit is not defective, this model (Archer C20) has 100 Mbps ethernet ports. If it's new bring it back to your retailer and try to exchange it to an Archer C2 which has Gigabit ethernet ports.

Thanks for all the replies - it took hours to read them all. So actually this router doesn't support gigabit ethernet, only 10/100.
