I have two Macs and a PC on a household network ethernet connection. Until recently I haven't had any problems. About a month and half ago however, my PC started actin' funny. Sometimes, it just looses it's connection. It used to be that I would restart firefox, or at worst, I'd restart the computer. Today however, I restarted the computer and I can't connect whatsoever. The little LAN connection icon in the lower right hand corner of my screen says I'm connected, but someone told me that doesn't mean beens. Anyway, all the other computers on the network work fine. So far I have restarted the router, switched the cables, checked connection, switched the ports they were connected to, and still no joy. Other than that my computer has never run better.

In addition I ran ipconfig then pinged 203.96.152.4 and got something like the following: 10.0.1.2 for my IP, 255 etc for my subnet and 10.0.1.1 for my default gateway

When I ping that IP I get request timed out three times and then it says "Ping Stats: packets sent=4 received=o lost=4 (100% loss)"

I am a confident Mac user and a relative noob to PCs (the ipconfig and ping stuff I got from someone on a different forum) so if you have any input, don't be afraid to use small words.

If you have XP-SP2 or Vista, you should use the built-in repair for the WINSOCK and TCP/IP stack. If you have XP-SP1 or earlier (and any previous version of Windows), you should use the Automated WINSOCK Fix all Windows Versions. I've included all the resets here.


TCP/IP stack repair options for use with Windows XP with SP2.

Start, Run, CMD to open a command prompt:

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reboot the machine.



TCP/IP stack repair options for use with Windows Vista.

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

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 machine.

You might also try either another cable, or Lan card

I did both the stack and winsock things and it still doesn't work. I also tried switching the cables around earlier.

Here's more:

This morning We noticed our printer wouldn't work and after talking just now with my wife I put together what's going on with that. I think the problems are related, but you let me know what you think.

When we first got this printer (a Brother HL-5250DN) We couldn't get either our two macs or our one pc to print. Eventually I got an email from a helpful tech I called at Brother who said there was a driver from a completely different printer that could act like one for a Brother. He showed me how to have the PC act as a sort of parent printer and then the macs would share that connection.

That worked great for a while until it stopped working and no matter what we did we couldn't get it to work. So we tried something else. We were able to print out a page on the printer (by hitting the start button three times or something) that showed the ip address being given to the printer. We were then able to set up ip printing. However when the printer got shutoff it stopped working and we realized that the ip was different (by printing out that page again). We updated the ip (a 192.169.1.x type number) and all was good. Today after printing out that page again I noticed that the ip had changed to something like 10.0.1.11. And we cant print.

Alllll that being said, my wife is convinced that somehow the pc may still think its in charge (by still having settings we didn't change when we switched from sharing to ip printing) or at the very least that since the PC cant print, no one can. Also I was just informed by the old lady that the printed out info page says it's connected to the router just fine.

I want you all to appreciate just how difficult this was for me to explain, I am really not that good with this stuff, so thanks for the help and THANKS for being patient with me.

What make and model is the modem and/or router. Also what is the ip address of one of the macs that can connect to the internet.
