Model: Archer VR2100

Hardware Version: V1

Firmware Version: 1.0.0 0.9.1 v009e.0 Build 191218 Rel.45551n

Hi, I'm using xDSL modem Archer VR2100 here in the Czech Republic. My provider is T-Mobile on VDSL2 metallic network managed by Cetin. In these days (by 1st June) there was increased upload speed from 10 to 20 Mbps for 100/10 plan. But my modem decrease speed from 10 to 7 Mbps. After some check line quality by Cetin and T-Mobile (everything is OK) I have tried the factory settings of modem, but no success - still 7 Mbps on upload. I used newest firmware 1.4.0_0.9.1. Last option was downgrade to version 1.0.0 0.9.1 (it is very first version that came with modem). And result? SUCCESS - my upload is now on 25 Mbps. So, it seems, that the latest firmware contains some bug inside, that makes the communication incorrect. Just for info for all with same problem.

@CZMik Hello,

Thank you for your valuable feedback. To locate the issue, can you help compare the DSL synchronization rate on Modem when VR2100 is on 2019 & 2020 firmware.

Go Advanced ---Status-- DSL , take the photo of the DSL part and send the photos to us

When Modem is on 2019/2020 firmware, please use the same device (better a PC wired to modem) and send us the speed test results, thank you.

Hi @TP-Link,

there are requested screenshots. All screenshots and tests has been made on PC with fresh install of Windows, connected to modem by wire (1 Gbps network card). Tests were done few minutes between them (time which was needed to flash another firmware version of modem). Network was without any comunnication (no IPTV, no streamed music, no other persons on my LAN). I'm reverting back to older version now again and waiting for release the new firmware. Thank you.
