Unzip the firmware download and then upload the .bin file?

Have you read

How to upgrade TP-LINK Wireless AC modem Router (new UI).pdf

which is included with the download? Do NOT upgrade the fw over wireless, use an ethernet cable.

I think some of the warnings about not upgrading the firmware over wireless are unnecessary really. The firmware is transferred over the HTTP connection, which goes over a TCP connection which should ensure it's transferred reliably, and below that layer then wired or wireless makes no difference. But we might as well do as we're told and use an Ethernet cable.

Ok, I managed to fix the issue with upgrading firmware, factory reset helped.

Obviously when swapping routers, I followed the 30 min rule.

Upstream   Downstream
Current Rate(kbps)   6948   45730
Max Rate(kbps)   7267   45746
SNR Margin(dB)   6.3   5.9
Line Attenuation(dB)   35.3   19.4
Errors(pkts)   1   150

Upstream is a little lower than it was with W9980 (about 0.5mbps less), downstream is about the same. What I noticed is the downstream attenuation dropped to 19.4 from 23.1 but for some reason sync is the same. Strange thing is that upstream attenuation went up from 33 to 35.3 causing lower througput I assume.

The worst thing I noticed it the pings went up by 2-3ms unfortunately. It is due to different chipset in router I guess? 6-7ms previously; 8-10ms now :(((

The only thing I don't like in GUI is Bandwidth Control requires rebooting the router in order to work. In W9980 I could just enable it without rebooting router.

Haven't tested WiFi on my SmartTV yet but will later. Tested it on my phone and I was shocked both 2.4 and 5GHz caught up full speed being 2 metres from the router but still. I couldn't get half of the speed on 2.4GHz being milimetres away from W9980

Will see how it goes in the next couple of days before I return W9980. I mean wifi strength, sync keeping, reliability etc.

The ping increase could be due to the different chipsets, but it could also be due to the fact that the VR900v1 is actually two separate systems inside a single box. It contains the wireless router part based on an ARM cpu running one operating system, and the VDSL2 modem part running another operating system on a MIPS cpu.

I understand what you mean.

I thought VR900 has much more powerful CPU than W9980. If the increased ping is due to its CPU rather than different chipset.

If I use W9980 as a VDSL2 modem (will connect DSL lead to it) and the VR900 just as a wireless router? Is that possible?

So obviously I'll plug the ethernet cable to VR900 so I assume pings will be back to 6-7ms as W9980 is used as a modem and not VR900?

I'm not sure you did understand what I said. I was thinking that the VR900 had a slightly higher ping because traffic has to go through two separate systems. So having the VR900 with a separate modem wouldn't change that, it's still going through two systems rather than one.

Oh I get what you mean now. Thanks for explanation.

I am just wondering if there is any way to lower bufferbloat, everytime I download something my ping shots up to 150-300ms. I tried to set up bandwidth control but it eats 7mbps of my bandwidth no idea why.. My current DS rate is 45730 and US is 6948 so I set 43500 and 6500 so thereotically it should give me 43mbps/6.2mbps  but it actually is 32/6 when testing any ideas why? It helped a little bit with ping but lost around 7mbps of my bandwidth somewhere.
