Please help me out:
It is textremely slow when I run a query in My SQL Server 2000 Query Analyzer on my laptop. But when I turn off the wireless card on the laptop, the query runs instantly.
Could you please tell me how can I make the server running faster when my computer is connected to the internet?
Based on the information that you've provided, the answer is simple. Use a cable instead of the wireless card to connect to the Internet.
