trouble with lcs app on i-pad 4

Did you update to iOS 8 recently?  If so, that could be the problem.  The LCS app may need a iOS 8 update revision.  Or a future iOS 8 revision may solve the issue.

I'm glad I updated to IOS 8 before starting to do anything with the LCS!

I loaded and used the LCS app prior to installing the iOS8 and have had no problems prior or after. Have you tried a cloud backup and restore?

Ha...talk about Windows...

But anyway, when that happens I double click the round button and completely close all the open apps. Then shut down the iPad by holding the side button until shutdown is available and then restart (reboot) it.

Thanks to all for the help. I gave up, installed the new update in the I-Pad and after 10 pages of designing my layout again back in business.Thanks again.

Well, we ventured into the LCS last night at Harry's place.  I ran across one oddity.  When you control the locomotive from the LCS on the iPad, the diesel RPM doesn't increase when you speed up, I couldn't see a reason for that.  It happened on both the Legacy E8's and the Legacy Sharks, our two test engines.  Is this just something I missed on the operation?  FWIW, they did work normally from the Legacy remote.

One other issue was that I couldn't get it to connect using WPS to the Comcast Infinity router, we tried multiple times.  It worked fine in stand-alone mode, but I'd like to be able to use the Internet on the iPad and the LCS without switching WiFi networks.

I had some issues doing that with Air Port router, but it worked eventually. So you went to the Comcast router software and looked for the Lionel WiFi signal and couldn't find it or found it and couldn't link up?

I'll have to try it again, I was just using WPS, as that's supposed to be "easy".  Since Harry didn't have the LCS power module yet, I took mine up, so I can't test here right now until I get a replacement.

I initially had a problem connecting to my home network with the LCS WiFi.  It turns out that the LCS WiFi uses 802.11b.  Your Infinity router may be configured to only support 802.11g and 802.11n.

Holy cow!  They really only use 802.11b?  I didn't realize that!  Truthfully, it never even occurred to me!  Is that really true?

I had my router configured for 802.11g/802.11n mixed, and I could not get a connection.  I reconfigured for b, g & n, and it connected.

Well, I'll be dipped!

That probably explains why WPS wasn't working, I'll have to check that here when I get another power supply module so I can run.
