Strange network access issue with 2 wireless routers and iPad

I have installed a second router on a LAN, configured as a switch/access point only, i.e. I have turned off DHCP on the 2nd router, and am using the LAN ports only, as a means of setting up a second wireless/SSID in an office about 60 feet away from the main router. (Windows networking environment).  The WAN port on the 2nd router is not used at all.

I've done this many times, and any computer that connects to the 2nd wireless gets an IP address fine from the main router, and sees the entire network no matter which wireless they are connected to.

When I connect an iPad to the main router's wireless, it sees two HP printers that I can print to.  When I connect to the 2nd wireless, it says there are no printers found.

What would account for this strange behavior?

You set up the 2nd wireless access point in a very standard way (and the way I do it as well).

Is there any chance your iPAD is picking up a stray wireless signal from another network?

Are you able to try a different wireless access point? It may not be compatible with the iPAD.

I assume you checked the IP, DHCP and Gateway addresses that the iPAD is using.

Another thing to check is Wireless Isolation on the 2nd Wireless network.  Most modern Wireless Access Points / Wireless Routers can isolate the wireless from the LAN. - Check for this setting, although it is not enabled by default.

I would do an IP Scan from your iPAD to see if it can see any other device on the network. (Fing is a great little IP Scanner for the iPhone / iPad).

As suggested above, check that you are connecting to the correct wireless network.

Use Xirrus (http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx) to see if there are any other wireless networks in range using the same wireless channel.

Can you find the two printers on the fing scan?

Problem solved - it appeared to be a bad 8 port network switch in the office.
