Solutions: Corrupted ARP cache is easy to fix

I recently began experiencing difficulty connecting my Dell (Inspiron E 15050) laptop to my home wireless network (using Windows XP).

When asking the system to diagnose the problem the response is: Wireless could not finish repairing the problem because the following action could not be completed: cleaning ARP cache.

ARP cache is a mapping of IP/hardware addresses. It's not something that you would normally be concerned with, except for when it somehow gets corrupted for any number of reasons, one of which is a known bug where somehow the routing service gets enabled.

Here's what you need to do to turn it off and clear out your ARP cache: Click the Start, Settings, Control Panel, Performance and Maintenance, Administrative Tools, Services. Scroll down to find and double-click Routing and Remote Services.

If the status is Running, click the Stop button. Make sure the start up setting is set to Disabled. Click OK. Open a command prompt (Start, Run, type CMD and click OK). At the command prompt type: netsh interface ip delete arpcache. After a few seconds it should return with OK.

Give the diagnose/repair another try.

I am trying to use my linksys router with my computer. It seems I have an IP address conflict. I've tried to get help from my Internet service provider and Linksys but the service provider couldn't help and Linksys wants too much money to help me. Do you have any suggestions? Can you tell me how to find my router IP address? From there I can do the rest.

The default IP address for your router is Open your browser and enter and you should arrive at the login page for your router. The default user is admin.

If you've previously set a password, enter it, otherwise if a blank password doesn't work try 'linksys' and if all else fails, do a hard reset of the router. This is accomplished by pressing in the reset button on the back of the router with a pin or other pointy object.

Once logged in you can do a soft reset or examine the IP connects/cache to see what may be causing the problem. And if your router doesn't have a password, give it one.
