| 1160077 | 2010-12-10 18:58:00 | Something else that occurs to me is what speed are the ports on the various devices ? if one of the PC's is using an older 100M nic it may have trouble talking to a Gigabit device, although they are supposedly compatible problems can occur. Also and this is a little tricky - if you have GigE capable devices at both ends of a cable that has only the 100M connections working (ie pairs 1&2, 3&6 but not the other 4 wires or even just one of them is faulty) it won't auto set it self to 100M and work because both ends detect the capability to run at gig speeds and the connection fails. An example at my place is a pc running over a 20M 2 pair homelan cable that has to be plugged into a 100M port on the modem to work and wont work on a GigE port of my switch. If you think it's speed related you can try forcing the connection to 100M abd that may help. A few notes about crossover cables. 1. Normally not needed as most NIC's auto crossover 2. There are two basic categories of device on a network DCE & DTE (data communication Equipment and data terminating equipment) DCE = Modems, Routers, Switches etc DTE = mainly the Computer itself but some other devices also are DTE Cabling DCE to DTE = straight cable Cabling either DCE to DCE or DTE to DTE = crossover cable. The exception to this is when using a router's dedicated WAN port (uses other names) which is already crossed over. A simple way to think of it is any device intended to connect directly to a PC is probably configured to use a straight cable (ie is a DCE) so the connection to a modem or switch should not normally need a crossover, but the connection between two routing / modem devices should when not using a special port. Likewise a pc-pc connection needs a crossover. |

| 1160078 | 2010-12-10 20:04:00 | Wayyyyyyyyy back in post#6 I asked whats the OS -- Still not answered ? Just a few Possible reasons for not working: Your TCP/IP stack or Winsock could be corrupted, to fix that,(hence asking what OS) ;) open a command prompt, type in the following commands to suit what ever OS you have: Reset WINSOCK entries to installation defaults: netsh winsock reset catalog Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log Reboot the Computer -- this will rebuild them. One "odd occurrence" I had sometime back: Lack of power to the router, and its failing under the load of two or more connections -With the working A PC going, try attaching another PC or laptop (other than B) and see if that does the same thing, or Disconnect A and only have B attached -- Does B now work ?? If so then the problem could be the power outlet is not supplying enough power. IF you have Vista or W7 Disable IPV6 If still not working, with B connected ( but not working) open the Command prompt - type in ipconfig /all - post back the results -- then connect the modem so it is working, and repeat. Edited: just a thought, one real easy test, with both A & B connected, boot PC B with a Ubuntu Live CD, see if the connection works. If it does, then its a software problem in Windows on B, if not then its the router not supplying the connection. |

| 1160079 | 2010-12-13 03:21:00 | My apologies for not answering regarding the OS: Windows XP Home. Let me re-describe the situation for possibly better clarity. (Forgetting previous problem description) - Windows XP Home computer - D-Link ADSL modem (DSL-320G) connects & works - no problems - Dynalink ADSL2 + Wireless 4 port modem (RTA1025WV6) – shows that the cable is not connected - tried a cross patch cable with the same results – cable not connected - moved the - Dynalink ADSL2 + Wireless 4 port to another computer & it works just fine – so this comfirms the Dynalink works Will try the Ubuntu boot Tues after 3pm and report back |

| 1160080 | 2010-12-13 03:29:00 | You have tried both cables between router and dynalink to rule out the cable yes? Okay, silly question, but the dhcp range is more than 1?.... |

| 1160081 | 2010-12-13 03:33:00 | Umm so why use the 320, if the RTA1025WV6 is a wireless modem/router with ports as well? | Speedy Gonzales (78) | ||
| 1160082 | 2010-12-13 03:34:00 | we're replacing the 320. with the dynalink and yes I did try both types of cables |

| 1160083 | 2010-12-15 04:00:00 | Update: installed a new ethernet card and all systems work! The computer identified that the cable was plugged in, was able to browse the internet etc. took the network cable out & plugged into the lan on board - nothing - cable not connected reconnected to the pci network card - worked! I would prefer to eliminate the pci network card if I can fix the on board lan. any suggestions? thank you. |

| 1160084 | 2010-12-15 04:06:00 | Well the onboard NIC is either dead or disabled. If its enabled then its dead, or faulty. | Speedy Gonzales (78) | ||
| 1160085 | 2010-12-15 04:09:00 | I would agree with you but when I connect the dsl modem to it (the lan on board) it works perfectly fine. |
