I seem to be having some problems with speed.
The download is fine always around the 670/750 so quite happy about that, but uplaods seem to change all the time.

I can do a speed test and I have had them as low as 9KB/s. I also have had packet loss. I was uploading to my webspace this is in redbus house so its UK and the upload speed was only 10KB/s then it jumped to 14KB/s for s short while only to drop down again. It sesems unable to keep a steady speed.

Decided to look at the configeration and see what dBmv I was getting.
Type : Ambit ETH/USB Combo Cable Modem
Cable modem : Ambit Cable Modem
MAC address : 00:d0:59:**:34:**
IP address : **.***.**.***
Downstream Receive Power Level : 0.62 dBmv
Downstream SNR : 33.24 dB
Upstream Transmit Power Level : 54.00 dBmv
new check gave me
Downstream Receive Power Level : 0.18 dBmv
Downstream SNR : 32.48 dB
Upstream Transmit Power Level : 54.00 dBmv
then 5 mins later
Downstream Receive Power Level : 0.00 dBmv
Downstream SNR : 33.09 dB
Upstream Transmit Power Level : 54.00 dBmv
another five mins
Downstream Receive Power Level : -0.18 dBmv
Downstream SNR : 32.83 dB
Upstream Transmit Power Level : 54.00 dBmv
another five mins
Downstream Receive Power Level : -0.25 dBmv
Downstream SNR : 33.24 dB
Upstream Transmit Power Level : 54.00 dBmv

the only one that is static is the upstream transimit power level. Weird as my uploads speeds are far from stable.
