I am running a Dell 7000 Laptop, 128meg of ram, with Win 98(FE), Axent/Symantec Raptor Mobile and recently installed a Motorola Surfboard 4100 modem via USB. This works well, but if I attempt to boot without the Cable Modem connected (i remove the USB cable,this is supposed to be a portable machine) Windows crashes multiple times after initialization with: Fatal exception 06 at 0028:00000017 (no module name given) eventually Zone Alarm indicates in failed to load, I lose my desktop and the system locks. Reboot with the modem connect and it's OK. I've already tried: 1. Setting up a Hardware Profile without the cable modem. When I attempt to exclude the Cable modem it instantly crashes the system and forces an automatic self reboot. The modem remains in the profile when I reboot. 2. Download new drivers from Motorola. The file I received has nothing that looks like a driver and Motorola is closed for the Christmas until Wednesday. I need to be able to connect to the WWW when I am away from home with DUN but want the speed of the cable modem at home. This is way beyond my understanding of WinDoze, although I do think it's in Networking or drivers. Anyone out there have any ideas or suggestions about what to change, where to look, how to find the module that's crashing or what to update to get this to work. Thank you in advance -- Arn

USB doesn't work that well with most cable modems I've seen. I recommend you install a NIC if you can and go ethernet; it's faster and much more reliable. The problem isn't with the modem or the service, but with the USB drivers and the USB interface. The first time you disconnect the USB cable while the PC is operating, your USB drivers will hose up and you will probably have to uninstall them using the USB uninstall program for the modem, and then reload them again. I personally think networking with USB is a waste of time as it is too easy to screw up. If you need the uninstall USB program for the SB4100, let me know and I will e-mail it to you. Without running that program, you will never get your USB driver for the modem to work right again once it is messed up.

Brian I was able to remove the USB cable while the system was up without hosing over my drivers, however it did lock the system and require a reboot. I have other USB devices on my system and they work well. I tried setting up multiple hardware configurations, one without the Cable modem, but that did not work. I gave up and finally managed to remove the USB drivers after many boots into safe mode until I finally got my system to boot normally without the USB modem. It was a nightmare because for some reason my CD-ROM did not show up in Safe Mode so I could not execute the removal program until I got my system back. I will get a NIC card and give that a try. -- Arn

USB is great for printers, mice, cameras, etc... It just doesn't seem to work well with cable modems on a lot of computers. I saw a PC a few weeks ago that developed a problem on the motherboard or powersupply (probably the power supply) that fed 110 volts out the USB plug. The modem's USB port was dead when I arrived, so I got another modem and connected it to my laptop first, where it worked okay on USB (the PC had only USB connections - you couldn't pay me to take one of those). When I connected that new modem to the computer, it actually tripped the main breaker in that part of the man's house. When he reset the breaker, the USB port was dead. We tried one more modem and when we connected it, smoke came out of it and killed it's (modem's) USB port as well. I don't know exactly what was wrong with the PC, but it could have possibly electrocuted somebody if it had that kind of power on the USB port and a person grabbed the other end of the USB cable. The machine had a surge suppressor strip he had purchased with the computer. I don't know why it didn't trip the suppressor breaker, but it never did, and it ruined 2 modems USB ports. I've never seen anything like that, but I will definitely be careful anytime I work around a USB device with any type of problem in the future.

To clarify my earlier statement, there was a lot of troubleshooting between trying the 2 modems. We tried everything we could think of to eliminate possible causes of a short before we connected another modem, but the smoked modem was the red flag. A problem of that nature would almost have to be power supply related because the power shouldn't have been there to burn out a modem anyway, unless one circuit of the power supply was bad. It actually burnt the metal on the side of the USB cables plug.

The "hot" and "neutral" are reversed on the ac outlet that the computer or modem was plugged into. This is more likely to happen with 2-prong outlets that 3-prong grounded outlets. If this happens, then the computer case will be at 120v ac. The shields in the computer cables are connected to the case, so they too would be at 120v. Unless you are grounded, you may never notice that this has happened if you touch the case. However, plug in a properly grounded device (cable modem, since cable will be earth grounded) and POW, tripped breakers, exploding computers, and more. The breaker on the surge protector didn't trip because the power went through the unprotected neutral side, not the breaker protected power side. A good surge protector would have been showing a wiring fault when first plugged in. In short (sorry, couldn't resist), the problem is most likely with the house wiring, not the USB port. It's very, very unlikely that 120v ac could be present at the USB port and the computer still work. Kent

Its the Raptor Mobile, depending on what version you are running and the OS. Raptor doesn't support XP yet and their 2000 client is pretty flaky as well. Try un/reinstalling the software. Make sure you have the Raptor configuration before doing this or contact your company's VPN support to reconfigure.

When I unzipped the archive all I found were the following files,no instructions,and none of files match my driver name, NET4100. NetMonCM.CAT NetMonCM.INF NetMonCM.SYS I decided to wait until I contact Motorola Tech Support before installing anything. They have one shot at a solution before I get a LAN card. I do know how to update drivers, I just want to be certain these are the proper drivers, they will fix the crashes and allow my laptop to be portable before reinstalling. Prior to the next install I am backing up my registry, system.ini and win.ini config.sys and autoexec.bat(last 2 are likely optional) Then if I have problems, I boot to safe mode, restore and I should be back in business. Due to my system crashing it was a nightmare getting rid of the USB Cable modem install. Arn

When I first installed the Cable modem software, Raptor was not bound to the Cable Modem and my system was crashing. After binding Raptor(running their install program)and binding the Cable Modem, it seemed OK and I had no trouble getting a secure connection. However, the other software I need for my client, Microsoft SNA with Attachmate Extra seemed a bit flaky on the high speed connection. I plan giving Motoraola a call tomorrow but will likely go with a LAN card. Arn

I agree it is unlikely the PC would still work like that, but what gets me is the PC itself functions fine. It seemed like a polarity problem would have affected the computer as well. Regardless, it's a dangerous situation. The man had his modem running on the same computer for 6 months prior to this happening, so whatever it was happened recently. The house was approximately 6 years old, so all the outlets are 3 prong gronded outlets; I'm sure the electrician may have taken some shortcuts when he put everything together, but that was a strange problem. The traces in the PC shouldn't have passed enough current to do what it did without killing the computer.
