The same one I posted before, check your signal levels, you might have a problem there. Have you contacted NTL CS about this issue?

thats what i thought paul... but during my 3years at Ntl tech support we used to get a few of these type of calls... even though the usb port was in use... xp still decided to shut em down.

Depends on power management I think and motherboard chipset. Some of the old VIA chipsets were terrible for USB connections.

is this the right test to use for my ntl:200 modem
http://192.168.100.1/
it keeps saying timeout

Paul K · 14-06-2005, 11:28

Should work, make sure you check in Internet Explorer that you aren't using a proxy on the connection. Also sometimes you have to reboot the modem for it to connect for some reason.

LFC fan · 14-06-2005, 11:53

ok rebooted modem and test works but which results to look at
i got
Upstream Transmit Power Level : 48.25 dBmV
Downstream Receive Power Level : -2.3 dBmV

Instructions were in the post lol
http://www.cableforum.co.uk/board/sh...t=26006&page=1
but Downstream SNR, Downstream Receive Power and Upstream Transmit power are good places to start.

LFC fan · 14-06-2005, 12:03

well these seem ok
Upstream Transmit Power Level : 48.25 dBmV
Downstream Receive Power Level : -2.3 dBmV
but not sure about this
Downstream SNR : 31.3 dB

Have you ever tried to connect the SACM to the PC via Ethernet to see if it still drops the connection? It would help eliminate the USB from the list of possibles.

XP will also shut down those that draw too much current. Having said that, it should tell you it's done that.

The first version of XP did have a problem where if you didn't have a motherboard with an Intel chipset, it would randomly switch USB ports off.

so do my results from the test look ok
also i have a printer connected by usb and that often dosent print saying theres a problem communicating with the printer and it works again if i unplug and replug it like the internet does
