Author Topic: Constantly dropping internet connection. 3 Macs - 2 Wireless, 1 Wired  (Read 3514 times)

Hi,
   I setup a D-Link DIR-825, VB1, Firmware V2.00NA about a month ago. We have 3 Macs here at home - 1 brand new iMac, a G4 Powerbook, and an old G4 / 933 Tower. The G4 tower is connected via ethernet. The other two through Wi-Fi. My problem is that I can barely use the internet for even a few minutes on the G4 tower, connected via Ethernet, without losing my connection. I can be in the middle of loading a page or an image, and suddenly it will say "Waiting for xxx.com". Then if I try to go to Google.com or something I will invariably get "Looking up xxx.com". The connection usually returns on it's own, but it can take up to 3 or 5 minutes. When I get this message on the ethernet G4 tower, I will also have lost connection on the wireless Macs.

   For the first couple of weeks the tower was not connected and we were just using the two wireless Macs, and they were working well. It seems that as soon as I hooked up the G4 tower via ethernet, connections became very flaky and intermittent all of a sudden. It's driving me crazy.

   All the Macs are configured for DHCP. We have a Time Warner cable modem. The G4 tower had previously been used at my office with it's own dedicated DSL modem / router, and it worked flawlessly for months at a time without dropping a connection.

   I've tried rebooting the modem, then the router, then turning all the Macs back on, several times. Same result.

   I just tried loading the new firmware but it didn't work. Said the Gateway was too crowded or something.

   I'm ready to chuck this thing out the window. We're not doing anything fancy here. I don't know why it should be so complicated.

   I would really appreciate any tips or things I might be able to configure to get everything working right.
 
  Thanks a lot - Steve

Does the G4 work if all other devices are turned off?
Check the cable between the router and G4 to make sure it's good?

Setup Static IP addressing on the router for your devices you connect to the router?

Does this router have Advanced DNS services? Turn it off if it does. Make sure Primary and 2ndary DNS addresses are filled in under Setup/Internet/Manual from the Status/Device Info/Wan section.

Try different browsers? FF, Opera, Flock... What ever supports the OS you have loaded on the G4. I presume 10.4 or 10.5?

Make sure OSX is up to date as far as you can.

Install a different NIC in the G4 to test? Some on-board NIC's can go bad however never heard of one going bad in a G4. Never hurts to try different though.
