I have a couple of 887VA routers under my management. I noticed that none of them is allowing for bigger than 10 Mbit/s transfers via WAN link despite being synced with ie 15 Mbit/s or 17 Mbits/s.
I tried different IOS images and ADSL firmwares but it does not change anything.

As you can see modem syncs with 15 M. I should practically get that speed sometimes (off peak hours). I measure that by speedtest.net but also tried to download via ftp from ISP's server etc. Never exceeded 10 Mbits. I have a 3 more routers connected to same ISP (Eircom Ireland) and same problems.
Is there anything on 887VAs that would stop reaching maximum bandwidth ?
I attached example config - dont look at acls as it was mostly removed. Also couple of objects etc to not include ip addresses.
