Access point cage match.

Q: I have a cable modem connected to a Linksys router for internet service. I am trying to connect 2 Linksys access points to the router in order to provide wireless internet to opposite sides of the building. I can’t get both access points to work at the same time. Whenever one works the other will not. The access points are not where they can communicate with each other. Any ideas why they will not work at the same time?

A: Their are two sticking points I see with the network you describe.

  1. Too many cooks. DHCP or Dynamic Host Configuration Protocol allows the devices on your network to request and obtain an IP address from a DHCP server. Linksys routers and some access points have built in DHCP services to make network setup easy. Unfortunately for you if you have more than one DHCP server conflicts will occur. So look up DHCP in the admin panel of each access point and disable the DHCP service if it exists.
  2. Same address. Just like every phone needs a unique phone number. Each device on your network needs a unique IP address. So you need to statically assign each access point its own IP address
    • Plug in the first access point
    • Access it via its default IP address of 192.168.1.245. (Remember that the default password for Linksys equipment is “admin”, with no user name.)
    • Simply changed the last number of the IP address to 246
    • After you save the changes you should be able login to the access point again via that new IP address. In this case, 192.168.1.246.
    • You can now plug in the second access point without conflict.

This would be a good time to enable WPA encryption. More on that later.

I have been earning my living in this way for several years. Alas, my personality doesn’t allow me to rest on the successes of my past. Entrepreneurs are cursed that way. I started SpyandSeek while still in college but never finished it. (slight ADD another curse.) After a two years in the PC trade I decided it was time to finish what I started and so SpyandSeek was born. SpyandSeek has analyzed thousands of HijackThis logs from around the world since it’s launch in late 2005. It still amazes me how a tiny site like mine can touch so many far off places.
