Would anyone have any idea as to why I might get an intermittent problem where my modem drops sync and keeps connecting/disconnecting every 5-10 secs. The problem isn't there all the time, maybe 2-3 times per week. Reboot sometimes seems to fix, but sometimes not. I have just had another bout of bing bonging as it drops in and out. I already have Windows firewall disabled but when I looked at the advanced tab in firewall it had my modem ticked as having firewall enabled. I have unticked that and it may be coincidence, but it's OK again at the moment. I'm running XP Pro SP2 with a PCI Conexant modem. PC has been great since I built it last Xmas, issue has arisen in last month or so. any ideas gratefully accepted. Thanks.
Copper access (BT lines can suffer from moisture in the connections (bit like humans and joints).If after trying different filters and it still misbehaves even in the dry, get BT to do a line check as the symptons also suggest a problem with out of bandwidth noise on your line.
Long long time ago, but thought a re-post might help someone else. Finally traced the problem after extremely time consuming trials. Tried swapping filters throughout the house in a structured, one at a time way. OK for days, sometimes weeks, then the dreaded 'Bing'. Went through all the suggestions above until finally ripped the junction box to bits where line enters my house and found dodgy connection with big bugger of a spider happily living on it. Spider re-housed in garden, comnnection fixed, box sealed with silicon sealant. Problem solved.
