Hi. I'm new in this site and living in Turkey. ISP said, your line supports VDSL 50 mbps down and 3 mbps  upload speed. I'm searching vdsl2 modem.  Found TP-link Archer vr200 and Zyxel Vmg1312-B10D for my budget . Which one I choose?

Hi. I'm new in this site and living in Turkey.

Welcome to the Kitz forum. 

ISP said, your line supports VDSL 50 mbps down and 3 mbps  upload speed. I'm searching vdsl2 modem.  Found TP-link Archer vr200 and Zyxel Vmg1312-B10D for my budget . Which one I choose?

I am currently using a ZyXEL VMG1312-B10D for my G.992.3 (ADSL2) service. I can confirm that device is capable of being configured for operation with G.993.2 (VDSL2) services.

I don't have any experience with the TP-LINK Archer VR200 device.

Welcome to the Kitz forum. 

Thanks a lot

I am currently using a ZyXEL VMG1312-B10D for my G.992.3 (ADSL2) service. I can confirm that device is capable of being configured for operation with G.993.2 (VDSL2) services.

I don't have any experience with the TP-LINK Archer VR200 device.

How about wi-fi performance Zyxel vmg1312-b10d?

How about wi-fi performance Zyxel vmg1312-b10d?

It is only single-band (2.4 GHz), 802.11n. I have very modest requirements but the WiFi is quite reliable in all rooms. I've just checked the current link speed and see it is currently at 144 Mbps. The lowest value I've noticed was 65 Mbps. So the WiFi link speed way exceeds my Broadband throughput speed by a considerable value.

Sorry I'm late. I bought Zyxel Vmg1312-B10D 2 days ago. Thanks for your advice  About 120 Turkish liras (£30). Yesterday came. Today I set and have a problem. Modem line rate 51mbps down and 4mbps up speed but when I test with speedtest wifi 38.5mbps down 1.6mbps up , with cable 39.6mbps down 1.7mbps. 

Here is my xdsl statics

I took a brief look at the various images that you have displayed in your most recent post and was somewhat uncertain as to what was causing you problems.

The synchronisation rate for a circuit will always be greater than any measured throughput speed and the two sets of values that you have noted show the expected result of the WiFi connection being worse than the connection using an Ethernet cable. That said, I am rather surprised to see that both measured throughput speeds are significantly below the circuit's synchronisation speed.

I am uncertain as to how your service provider has provisioned the circuit. I would say that a ping of 12 ms would be quite reasonable in the UK and coupled with the high number of CRC errors being reported, along with no FECs, makes me believe that your circuit is currently operating in fastpath mode.

In the third image, the very odd value reported for the Received Power (in the Upstream column) must be the result of either overflow or underflow of a signed integer. That is very much an error of the VMG1312-B10D hardware and is not something that I have seen before. As such, it will not cause any problem. It is just an annoyance.

I would suggest that you carefully recheck the configuration of the VMG1312-B10D and ensure that everything is set as required for a service from your ISP, then give it some time and see if the DSLAM (at the far end) will react to the errors and adjust the current configuration.

You may find it easier to access the device either by telnet or ssh and then look at the statistics by using the xdslctl info --stats command. Granted, I do not have a G.993.2 (VDSL2) service, but here follows an example of what that xdslctl command line displays for my G.992.3 (ADSL2) service --

I think that is a lot easier to examine -- and show to others -- than taking a sequence of screen-captures from the GUI.
