Need help - wired client computers are losing internet
by DeveloperWarren - 12/5/12 3:01 PM
I have a persistent problem where every 20-50 minutes all "wired" computers in my house lose internet connectivity, but all wireless computers stay connected with no issues.
When my wired computers lose connectivity, it takes some 8-12 minutes for them to regain it, even if I release/renew on the individual machines.
Here is my setup and what I have tried.
CenturyLink DSL into Actiontec C1000A modem/router.
- This router is new...I called Centurylink when the problem first started (not realizing wireless clients were never losing internet) and they shipped a new modem (same problem with new modem as with old).
Port 1: DirecTV adapter's connected by cat5 cable directly.
Port 2: Switch-A connected by cat5 directly.
Port 3: Lenovo Laptop (Win7) connected by cat5 (from across the house, through walls).
Port 4: Switch-B connected by cat5 (from across the house, through walls).
Switch-A and Switch-B are both DES-1005E models form D-LINK.
Switch-A has connections to:
Win7 Desktop by way of cat5 through walls to another part of house.
Macbook pro laptop by way of cat5 through walls to another part of house.
Switch-B has connections to:
DirecTV "Genie" DVR
Sometimes Macbook Pro if we are streaming onto TV
60" LED TV
Wirelessly we have various iOS devices and sometimes the Macbook Pro, none of which ever lose internet connectivity.
When we lose "Wired" internet access, wired devices can still see one another (I am generally remote desktopped from my win7 desktop to the T400, and never lose this when internet goes down), but none can reach the internet.
Further, none of the wired devices can access the Actiontec router admin (192.168.0.1) when an outage occurs, but all wireless devices can do so without issues.
Switch-A used to be an older switch of mine, and I thought maybe it had gone bad, but having replaced it with a new one the problems persist...plus even the devices that are not switched lose access.
Thank you so much for any help as I try to isolate the problem and troubleshoot.
