My Win 98 Dell C600 Latitude is hooked to the net via a B-FOCUS 270 DSL modem. The line infrastructure (brand new line) was tested by the phone company and is Ok. However, every 10 min. or so, networking activity stops for no apparent reason, then after 2 min., it resumes. When it works, it's great. There is no system freeze associated with the stop. It's just Explorer (or Firefox) that suddenly stops fetching URLs. Lights of the modem are still on, except the "networking activity" light. Dialup tray icon lights display a quick flash or two and then go off for 2 mins.
Support forwarded me to search for "243199" in support.microsoft.com, where I found a patch for the problem - but that was probably a false call because there is no change.
I looked for viruses etc. but found nothing.
The same system was hooked through a cable modem with no such issues. I moved to DSL because of mainly price differences and some bad service with the cables.
This is a little urgent, because if I can't solve this, I'll consider cancelling the DSL service.
