Hello,
this is my first post to this very interesting forum
I am a FastWeb customer in Italy and, as you probably know, this is the modem sent by them for the new VDSL2 service,with firmware version 10.4.B.B
I have been using it since a couple of months (still in ADSL+ mode), and so far it is very stable and the performance look ok.
WIFI is probably a little weak, and I remember I had to reset the router once because the wifi was not working anymore (even if ethernet was still working).
I would like to report here a very peculiar problem I have, which is (apparently) related to the QoS IP management, at least with the current firmware.
I am a linux/ubuntu user, and since the beginning I have been unable to download files from remote servers with the standard scp/sftp commands: the transfer goes to "stalled", after few seconds. Uploads instead work correctly.
The problem is client dependent, for example downloads work with windows, android, and also with winscp under wine.
After various tries, I found that scp/sftp downloads are "unblocked" if I use the ssh option IPQoS=cs0 . For example:
scp -oIPQoS=cs0 host:file1 ~/file1 -> works perfectly
scp host:file1 ~/file1 -> transfer gets stalled
Something is wrong in the IPQOS configuration of this router, and probably here somebody can confirm the issue.
I think that using the Thomsom CLI interface the problem could be solved, but I am not very expert with it
Thanks!
