Reply To: ASUS DSL-AC55U – G.INP Hey guys, I have a few questions regarding G.INP (G.998.4) on my DSL-AC55U. When I enable just G.INP (or after a factory reset, the G.INP is enabled by default?) the…

Hey,

I bought a modem TP-Link W9980B (~54£) yesterday. The reason was particularly to try out some cheapish modem with a different chipset.

I never thought that it is so hard to find a good quality modem here in the Czech Republic. I think the reason for it might be that local DSL infrastructure works with a greater part on Annex B and as Annex B is almost unique just to the Czech Republic it is not a good reason for many manufacturers to make many models or none at all.

As the TP-Link W9980B uses a Lantiq chipset it should be better than Broadcom on a long line. It happens in my case to be at one. The technician told me that it might be approximately 700 meters.

And it appears to be a bit better. It synced at the same speed as my ASUS DSL-AC55U but with a better SNR Margin. But as I am able to tweak SNR on AC55U I am able to attain a little greater speed on the AC55U.

DSL-AC55U 57 Mbit 3dB SNR Margin
W9980B 57 Mbit 6db SNR Margin

But apart what I mentioned.

From my point of view, the TP-LINK has a TERRIBLE INTERFACE. It was very difficult for me to navigate around and finally, when I reached the DSL settings I found out that there is pretty much nothing. You can choose between VDSL and ADSL. And that’s all. And apart from that, the modem comes with a factory firmware with no available updates for ANNEX B version. I looked up that last firmware for a different ANNEX version is dated back to 2015. Awful.

Thank god we have ASUS.

And TP-Link? I am going to return it on Thursday…
