UNDOK Roberts iStream-3

Chalmers57 — Sun, 18 Apr 2021 15:00:00 GMT

Recently moved from Virgin to BT with Smart Hub & a disc. Prior to this my UNDOK app. worked fine with the router & iStream radio. Now the radio cannot be found, despite showing as connected to the router. I have been through BT technical support & Undok too. It seems the only solution is to install a second 2.4ghz router & login our iPhones & the radio to this to use the App. Not exactly a step fowards 😢 has anyone else found a better solution?

Does your iPhone connect to the BT Smart hub over wi-Fi, successfully?

You could try connecting the iPhone manually, before running the UNDOK application.

Thanks, how would I connect the iPhone manually? I have tried the BTWifi connection from the router, this should be 2.4ghz I think but the radio does not show up on UNDOK . I believe the iStream only connects to 2.4ghz and the iPhone defaults to 5ghz

Yes, that worked. I screen shot the Wi-fi connection when it (randomly) connected. I then entered this manually and UNDOK found the radio immediately. However the problem is..... this is not an elegant solution 🤔

Looks as though you are very nearly there.

From the Hub Manager, disable the 5Ghz.... On your iPhone, clear your wi fi connection....re enter wi fi connection details. Then run UNDOC again. Does it work on 2.4 GHz?

Re enable 5Ghz on the hub manager. Does it still work?

Well, it worked when 5ghz was turned off. Worked when I turned it back on. However once I disconnected Wi-fi & reconnected again on the iPhone it was gone. This I think because iPhones will always prefer 5ghz & Roberts, at least this one, iStream-3 only connects at 2.4ghz. So far I am stuck at manually connecting Wi-fi to enable UNDOK to find the radio.

I think there was a post in this forum that suggested that device on a 5Ghz network couldn't cross over to see a device on the 2.4GHz network.

Once solution is to 'forget' the 5Ghz password for your network on the iphone, so the iphone will only be able to connect to the 2.4GHz network

hi Lynda, the PW for 5ghz & 2.4ghz is the same as far as I can see, also you can’t “see” which channel you are connected to. I spoke to BT who said one solution would be to disable 5ghz but the internet & bandwidth would be heavily compromised on 2.4ghz only.

Which was disproved as I can connect to a 2.4Ghz only printer with a 5GHz connected laptop. I think others reported the same.

I think that the problem lies with the iPhone and the Smart Hub...You can’t separate the 2.4ghz and 5Ghz connection, either on iOS or hub. BT are correct in this and suggest disabling the 5Ghz on the hub. Pity the Roberts doesn’t connect at 5Ghz!

Really! or some way to distinguish on an iPhone between the 2.4 & 5ghz channels.
Oddly my iPhone occasionally connects via UNDOK , I’ve tried capturing & copying the settings but that doesn’t always work either. I had no problems with the Virgin router.

You can’t force the iPhone on iOS at it’s current version, to connect to 2.4ghz. It defaults to 5Ghz if that signal is there.

If you disable the 5Ghz on the hub initially, then it will connect to 2.4 GHz. Then, if you reinstate 5Ghz, the iPhone remains connected to 2.4ghz and the 5 GHz is still available to other devices....That’s until you switch off the iPhone, or go into flight mode, then you are back to square 1. This is what the o.p. Is finding out.

Only way is to keep the iPhone permanently powered up with wi fi enabled....until the battery goes flat, then you are back to square 1.

Hi,

The Roberts are great when they work, and some (R100) can be temperamental, and like you, I seem to be subject to the occasional issues. I’m assuming you’ve cleared the settings in the UNDOK app, though I admit I can’t find it in the iOS version, but it’s through the ‘cog’ in the Android version.

Otherwise, I’ll just second the early thoughts of an ‘overlay’ : I run a cheap Tenda Nova mesh in bridge mode almost just to do only this for 6 varying Roberts and a couple of other Frontier based devices and it generally works well enough, and supports PiCorePlayer and LMS so I can ‘cast’ BBC Sounds through UPNP most of the time.

Sorry it’s not much help, but you are not alone.

thank you for sharing 🙂 I found I could connect sitting in my car this morning and randomly it does allow me to. I can’t find any way of flushing the UNDOK App. in IOS unfortunately and I have tried reinstalling many times.
