Losing Signal after Few Days

by wrytat / May 21, 2006 10:16 AM PDT

We have a computer in the network that is switched on almost every day. There is a folder in its hard drive that is shared with users of other computers. And it's installed with MS SQL 2005 Express Server that is used for a program run at other computers on the network. It connects to the network using wireless adapter. The problem we are facing now is that, after being left switched on for a few days (2 or 3), it suddenly couldn't be detected by other computers. We tried to ping its IP address, but there's no response. But after we restart the computer, it's available on the network again.

Does anybody know why this happen?

Sounds like a HW or driver problem to me

Why have you connected a server using wireless?
Try a newer driver or a different NIC.
You really should try to make this an ethernet connected server.

What is a different NIC? There are areas in the company that it is impossible for us to lay those Cat-5 wire, e.g. the factory. That is the reason why we are using wireless.

In reply to: NIC

Network interface card. (wireless or ethernet)

One other option is to use a wireless bridge.

Network---(AP) (bridge)----[server]

The server can use the ethernet NIC to connect to the bridge. The bridge will connect the server and any other devices connected to it it, to the AP.
DLink, Linksys and Netgear all have a wireless bridge product. You can even replace the antenna with a directional to increase the signal strength.
