Cisco 887 slow Wan

Hi,

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.

#show controllers vdsl 0

Firmware        Source          File Name (version)

--------        ------          -------------------

VDSL            user config     flash:vdsl.bin-A2pv6C035j1 (10)

Modem FW  Version:      120330_1738-4.02L.03.A2pv6C035j0.d23j

Modem PHY Version:      A2pv6C035j0.d23j

Vender Version:         Ap6v35j.23j 68

Speed (kbps):             0            15354             0              1021

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.

#show interfaces fastEthernet 0

FastEthernet0 is up, line protocol is up

  Hardware is Fast Ethernet, address is 442b.03cd.7a9a (bia 442b.03cd.7a9a)

  MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation ARPA, loopback not set

  Keepalive set (10 sec)

  Full-duplex, 100Mb/s

Hi,

Ask your ISP about this issue. Check SLA agreement with them.

When I connect stock router that comes from ISP works at full speed.
