If it is at or around 100Mbs, I would suspect the Ethernet cable. You need a good CAT 5e or better.

Do you have BANDWIDTH control on? Might restrict you if you do.

 

Another thing to try to rule out the router is to change the MAC Address of the router to that of your PC? If that works, then you probably have not rebooted the modem. When you replace the router, the modem remembers what was last connected (PC?) and needs to be rebooted to see properly the replaced device.

 

Also, I assume when you test with the PC you used the cable connected from the PC to Router and connected that to the Modem. If not, possible the router to PC cable is the cause as it can't handle the new speed. A CAT5 or even a CAT5e cable (might be marked on the cable) could restrict you to 100Mbps. Need a CAT6 or better.

 

Have you tried all 4 ports by the way? Possible one is not working well of has a restriction in it?

@Markomyt1 

 

The Archer C50 has 100 Mbps Etherent ports so you will not see anything higher than that.

 

You want a router with gigabit ports like the Archer A6.

Thank you - All good feedback.

 

The point I was trying to make is that the speedtest was even slower than before the upgrade with the same router.

 

Oh well. I picked up a TP-Link AX3000 Gigabit Router and everything is working great.

 

Cheers!

There could be any number of reasons for this.

 

• Router not set the same as old router (Security, Channel, width).
• Device remembered old setings if using the same SSID.
• Cable connection problems.
• Wifi Interference due to a different signal strenth.
• Other too...

I agree, but just odd that throughput was slower on the old router with nothing except the modem changed.

I really like the new AX-3000
