Cannot access LAN resources when connected via wireless

lanrouterwireless-networking

My ISP provided a BEC 7800 TN R2 router with wireless capability for my home. I have a Windows desktop computer connected via Ethernet cable to the router. I have no problems with my desktop computer. I also have a Windows laptop. Both are running Windows 7.

When I connect my laptop via Ethernet cable, I can…

  • Connect to the Internet
  • Connect to router admin page
  • Ping the desktop computer
  • Access the desktop computer's shared drive
  • Remote Desktop Connection to the desktop using either its Windows name or IP address.
  • Print to the network-connected printer

When I connect my laptop to the router via wireless, I can..

  • Connect to the Internet
  • Connect to router admin page
  • (but nothing else)

I would like to access LAN resources (desktop computer and printer) when connected wirelessly.

The wireless page on the router, looks like this:

You can see that my router supports "Client Isolation." However, I do not have that feature enabled. Just for testing, I enabled it. It made no difference. I disabled it again. No difference.

When I connect my laptop via Ethernet cable, I get…

Question: Can you suggest what configuration change I need to make so that I can access LAN resources when connected wirelessly?

Best Answer

I posted the original question four years ago. In the eight years that we owned the router, I never was able to find a solution. Last week, we replaced the router and the new router worked perfectly without any special configuration changes.

One possible workaround was suggested yesterday by @Kinnectus, "...a configuration where you have to VLAN the wireless to the LAN." That may work, but I cannot try it any longer since we upgraded.

My conclusion is that it was a shortcoming of that old router. The solution for us was to replace the router.
