| 142244 | 2003-05-07 23:45:00 | My computer has a 600MHz processor, 64MB RAM, 20GB HDD, a Lucent Winmodem and a Surecom 10/100 network card. My problem is that I can have either the modem working or the network card working but not both at the same time!!! - when the modem is working (connecting to the Internet) my computer cannot see my other computer ("Unable to browse the network") - if the network card is working (can connect to my other computer) then the modem can't connect to the Internet (unable to negotiate a compatible set of etc) I have tried - installing a different network card - same problem - removing/reinstalling TCPIP, DUN, all network components (including removing DUN components from the registry). Anybody got any ideas??? DavidC |

| 142245 | 2003-05-08 02:58:00 | I would look for an IRQ conflict | beama (111) | ||
| 142246 | 2003-05-08 05:00:00 | Whoops, I forgot to mention that my computer is running Win98SE. I don't think it's and IRQ conflict. Device manager shows the modem is using IRQ10 and the network card is on IRQ11 |

| 142247 | 2003-05-08 05:08:00 | The modem and network card will both steal memory from the motherboard for their buffers. With "only" 64MB, you probably haven't got enough for both. That's just a guess. :D |

| 142248 | 2003-05-08 06:19:00 | What a strange problem. It could be a memory problem as Graham suggests, or maybe more likely, a quirk of your winmodem, they do tend to have minds of their own. Sometimes funny things happen with a PCI slot that shares IRQ with with say an AGP slot. So even though there is no conflict showing in device manager problems may arise, but have to admit that doesnt really add up. Still, if you have spare slots try moving the modem around. Im grasping at straws here :) Using an external modem would solve the problem, but thats a cop out to finding the cause of the current problem. |

| 142249 | 2003-05-08 09:51:00 | heres another thought, Try going to the bois and checking memory addresses the modem and nic maybe using the same address range | beama (111) | ||
| 142250 | 2003-05-08 13:46:00 | I assume in your network protocls you have a TCP/IP -> Dial-Up Adapter and a TCP/IP -> 10/100 NIC Card or similar... if they are both fighting over the same protocls that is likely to cause problems... |

| 142251 | 2003-05-09 05:15:00 | Nope . The TCP/IP protocol is bound to both the interfaces . Each uses its own stack . There is no fighting at that level . I suspect the memory shortage, because there are no error messages (reported) . If there are interrupt conflicts, both would start . They just wouldn't work . . . often just hanging the machine . Can you borrow some memory (from the other machine, perhaps) temporarily? |

| 142252 | 2003-05-09 07:03:00 | the only things i can think of off the top of my head is if you have been tweaking out the mtu/rwin settings. it pays to set these back to default before redoing the networking. also uninstall any firewalls and clean out any spyware. |

| 142253 | 2003-05-09 08:29:00 | i had some problems with nt4. the hcf modem and realtek lan card. solution: i used a 3com card instead. this not happen on win95 |
