connection loss
 

hi

i have another problrm
my internet connection keeps disconnecting randomly.
the modem just stays the same, no lights flash or anything and if i simply unplug the usb cable from the modem to my pc and reconnect it works again.
this is really annoying in the middle of pes4 match online.
i cant figure out wat is wrong
is it something to do with my computer or the service?

Re: connection loss
 

If the lights on the modem aren't changing and connection resumes when you pull and replace the USB then it's probably PC based.
Have you got any firewalls that might be interfering with the connection? Are you restricted to USB or do you have a NIC installed?
Does it happen only when you are using your connections in certain ways or randomly?

Re: connection loss
 

you need to try a ethernet card in your pc the usb are renown for using up pc resources

You just beat me on that Paul lol:D

Re: connection loss
 

its just randomly
and as i have x box live i use the ethernet 4 that

Re: connection loss
 

could also be the pc is disabling one or more of the usb ports if u have a power schem enabled..

u can check if u have power management enabled on the usb ports by going to the control panel... double click the system icon,, then onto the hardware tab...then the device manager button....
at the bottom of the list there shoud be the universal serial bus controllers... if the list isnt expanded just click on the + symbol by the side of it to give you the usb root hubs.

right click on each one ...if there's more than one... and choose properties... then click on the power management tab at the top... and untick the box for 'allow the computer to turn off this device'

hopefully should sort it for u... or worth a try anyways...

Re: connection loss
 

SACM or set top box?

Re: connection loss
 

i use cable modem

Re: connection loss
 

Have you checked your signal strength?
Also are you clean as far as virus, trojan and spyware etc are concerned?
Does the connection drop even if only the PC is connected?

Re: connection loss
 

50420 do i do this just on the usb root hubs

Re: connection loss
 

aye

Re: connection loss
 

how do you check signal strngthim pretty sure im free of viruse and spyware as i done a check 4 both yesterday and had same problem 2day
and yes it drops even if only pc is connected

this is really beginning to p**s me off
was one nill up then connection lost and my internet wouldnt work

Re: connection loss
 

not 100% positive as to wether it would requiere a restart.. but it wouldnt do any harm i suppose

Re: connection loss
 

It doesn't as far as I know but normally the computer will only power down USB ports that aren't in use as it's part of power management.

Re: connection loss
 

anymore suggestions then

Re: connection loss
 

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

Re: connection loss
 

how do i check the signal levels m8
sorry im not very good at this sort of stuff

Re: connection loss
 

Instructions here
http://www.cableforum.co.uk/board/sh...t=26006&page=1
they work for the majority of SACMs. When did this problem start?

Re: connection loss
 

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.

Re: connection loss
 

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

Re: connection loss
 

its been happeninf 4 as far as i can remember
just never been 2 bothered about it till started playin online games

Re: connection loss
 

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

Re: connection loss
 

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.

Re: connection loss
 

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

Re: connection loss
 

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.

Re: connection loss
 

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

Re: connection loss
 

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.

Re: connection loss
 

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.

Re: connection loss
 

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

Re: connection loss
 

Numbers look ok, nothing sticks out as beyond the thresholds.
That could be pointing to a USB based problem, have you thought about using the connection via ethernet and a router?

Re: connection loss
 

well i may hav to
but is there anything else i can do if its the usb thats causing the problem

Re: connection loss
 

You could try getting a PCI card with USB ports, they aren't expensive these days and if it is your USB chipset on the mobo failing it will give you a workaround.
