Region : Argentina

Model : TL-R470T+

Hardware Version : V4

Firmware Version :

ISP :

Hi All, I got a new Modem for TWC (Time Warner Cable) to allow access to 300 Mbps. With the TL-R470T+ v3 I used to get up to about 100 Mbps. But now I only get about 25-30 Mbps.

Any thoughts? is this just a hardware limit? I only got this in May so I would hate to need a new one.

What's speed if your PC is connected to new modem directly?

There is an instruction which may be helpful for testing the speed...

Was this ever resolved? I'm having a similar problem with my ER5120. I was regularly getting my max speeds from TWC (50/5) then I upgraded my plan and modem to 200/20. Now, I'm able to get full 20 upstream but cannot get above 30 down. I know that it's not a wiring problem because I can get the full 200 if I connect directly to the modem.
