iRFR: iPad & Ion problem

Can anyone throw any light (sorry!) on this infuriating problem, I wonder?

We have recently bought a new Ion, running the latest software. Bought a new Wi-Fi router, set up a new network, and configured it as an access point - with no internet access. We want to be able to use an iPad running the iRFR app, as a remote - so that we're more easily able to focus 96 new (overhead) scans with it.

Installed the app. All OK so far. Got the iPad talking to the Ion after a few hours of faffing about with the router configuration. However this was only for a glorious hour and a half or so! When it finally connected (it wasn't actually too clear how this happened though!), we were able to stop and start the app numerous times during this period. It always reconnected with the Ion, and we had complete iRFR functionality, every time. We thought we'd finally cracked it, so exited the app again and switched network connections on the iPad, went on the internet, etc. in order to test if it would reconnect after switching back to the new network using the new router again.

We still haven't managed it! - It's been a few days, now, and it's driving us nuts!

There are some odd things going on though. It appears that the router is OK - we can access the Ion from a MacBook using the same network. On the iPad if we go into Settings/Console it sees the Ion, and when we test the connection we get full blue bar read-out and it 'dings' to say it's connected. However, when we hit the connect button on the welcome screen, we just get a message saying "No connection - Disconnected from host"! Quite often, on multiple attempts to 'Connect' the Ion appears for a split second in green, and the 'Virtual RFR', 'Cue List', and 'Playback' lines become bold - but never longer than a second or so - before we get the "No Connection" box  again. It's as if it's connecting and then something causes it to drop the connection. This is what was happening when we were originally attempting to connect. Then all of a sudden it connected. We thought it was something we'd done to the router, but actually when it connected this one and only time, no one was doing anything!

So, there you go -

We've tried everything we can think of, including trying all the available wi-fi channels on the router, but as yet no success. It's behaving like a physical "loose connection", or like losing a 'phone signal.

ANY suggestions would be extremely gratefully received.

  • Howdy Onebrow, check in the WLAN Network settings in the Iphone and make sure the iphone has an IP in the same Subnet as Ion , ie 10.101.124.101 or so.
  • Thanks Corey, but yes, the IP addresses are all in the same range, and subnet - the Ion, router, and iPad

    The iPad has been assigned a static address of 10.101.125.101, subnet is 255.255.0.0 and all three DHCP settings have been disabled.

  • What is the IP of the Router? Do you have a WEP/WPA on the WLAN? Are there any special settings/functions turned on in the WLAN?
  • Hi Corey -

    Sorry - I'm on UK time here, I assume your in the States.

    I'm off-site at the moment - finished for the day - brain fried!

    Tried to reply using the iPad, but was unable to 'write', as the wiki appears to use Flash for that, and of course that won't work on an iPadt!! Ha! Ha!

    Anyway back on good ol' Windows now - VPNing into my work machine from home.

    I will probably need to come back to you tomorrow when I have proper access to all the items on the network, but off the top of my head I think the router IP is 10. 101. 1. 1 

    We're not using a WEP key or WPA on the WLAN, because we're not using the WLAN. The Ion is using a LAN socket to connect, and the authentication is WPA - PSK  with AES encryption. As far as I'm aware there are no special functions/settings turned on in the router.

    I'm afraid that's the best I can do for now.

    I will confirm all this tomorrow.

    Thanks for your interest and assistance on this.

  • Hey Onebrow, I am based out of our Germany Office. You are using a WLAN to connect from the iPhone to WLAN Point / Router which is then connected via Ethernet cable to the Ion. Could you turn off the WPA-PSK Excryption and see if the problem goes away?
  • COREY: Sorry, slip of the acronyms there! My brain saw 'WAN'.

    Back at work now. I will try that a.s.a.p. today (there's a lot of other stuff going on though), and get back to you.

    BRIAN: Thanks for you input. I too think that the root cause is something to do with the wi-fi, and also know someone that has the a similar problem - only the other way around - the Mac can't connect but their iPhone can. So they're OK! However, I have tried changing channels. In fact, I've tried every channel available on the router actually, but it has absolutely no effect on the issue - whichever channel we use, we get the same symptoms.
