Hi. I have retried to replace a BT Hub 4 running BT Infinity with a 2850n but connection is terrible :evil:

2850n is on latest firmware v2850_364_2471201.zip . It connect and seem to sync with a good speed but keep getting ping timeout and connection lost. Connection unusable. I left connection overnight hoping it would settle down. But no luck.
Trying BT Wholesale Speed test sometime result with page unable to load.

This is my vdsl status , does my SNR look too high?



And here is a speed test log. The start is with BT Hub, then I change to 2850n and you see the packet lost & ping goes up. Towards the end I switch back to BT Hub and the packet lost disappear, connect is now useable.



Anyone got any suggestions please? I am willing to try any beta firmware if any are available?

Many Thanks

Hi
Firmware 3.6.4 has fix the speed issue but seems it has a mismatching or conflict ... i have issue with wan 2 ... other users with DNS lookups etc ... i would say to contact the support (the main point of my reply) ... they are the ones may have beta for testing

About SNR seems is not high ... just the draytek seems not has the decimal (comma or full stop) so your SNR i would say is 12.9 Up & 11.4 DOWN but check with support as well
I also see few errors with upstream so ask this too

Thanks babis3g I will contact support

Try out the 3.6.3 firmware, it has a different VDSL modem code, it can be found on ftp://ftp.draytek.com

Contacted Draytek support and they instructed that I try and disable QoS & DoS defence if enabled. They also sent 2 different firmwares to try. I will be trying over the weekend.

Hi

Did you find a solution to this?
