Hi Guys,

I have a problem that has just popped up with my home network. I use a lot of remote apps on my IOS device (old Iphone 4S) such as iTunes remote, xbmc remote, VLC remote etc etc.

I also have a multi router setup with two wireless APs, each with separate SSIDs (Lets call them lounge and garage)

All of these remote apps have just stopped working on my iPhone when connected to one SSID (lounge), but they work fine when connected to the other (garage). They were working fine from both last week. The interesting thing is the Apps all work on my iPad on the same SSID (lounge) that my iPhone has stopped working on.


Details of my network are:

Netgear N600 DGND3700v2 - Set up as my Modem/Router/HDCP server - This is also the "Lounge" SSID (both 2.4 and 5G)
This router has my main PC (with iTunes and one xbmc programme that the remotes control), my DVR, an 8 port switch in the lounge and a 4 port switch upstairs

Dlink Di-704up - This is the above mentioned 4 port switch
This just has laptops in a small office connected

Netsis 3108G switch - This is the above mentioned 8 port switch in the lounge
This has the garage wifi AP, a Raspberry Pi XBMC box (one of the other xbmc programmes I remote control) and an xbox connected

Dlink DIR615 - This is the garage WAP with the Garage SSID that seems to be working fine.


So far I have tried to power cycle EVERYTHING, I have tried assigning my iPhone different IPs on the lounge SSID, both Static and DHCP. I have tried hard resetting my phone.

Im now at a loss as to what the issue is. Nothing has changed on the network since it was last working. But I find it extra weird that my phone works when connected to the Garage AP (which is like 3 jumps down stream from the device I want to remote control), but not when connected to the same router as my PC I want to remote.

My iPad works fine with the remote apps on any of the wireless networks.

Does anyone have any idea where I should start to fault find this?

Let me know if I need to provide any further details etc.

Cheers,
Sam

Make sure that the IP's and gateways are all identical, that there isn't any network differences across the WAPs.

Something must have changed between it working and it not, firmware updates on your phone, access point, switch if its a managed switch, physical or software changes on your equipment?

The only thing I can think that has changed in the last month or so it my phone was updated to IOS 8.0.2 but I would have thought that because the remote apps are working on this phone with this IOS, on the "Garage" wireless, that it proves the IOS is not the issue.

Is there any way I can get my phone and the "lounge" router to forget eachother entirely and reconnect with a fresh DHCP address etc?

I have tried to "forget" this network and assign different IPs, but every time I connect it back again with DHCP assigning an address, it always gets the same IP. Is this because there are some setting cached somewhere, or will it just be because its the next available address on a small network?

One other point to note, it my MSTSC app on this iphone works fine when connecting to the same Server the XBMC/itunes software is on, so all the normal networking is working fine, just not these "discovery" type services.

What settings are you using for your DHCP lease time, perhaps making the lease time shorter will get you a different address otherwise try setting a static IP.

It may be that your WAPs are sending multicast packets or broadcast packets, there are a multitude of settings that could possibly cause the issue and with your complex setup you may want to read up about wireless networking.

Go through all the settings on each of your WAPs (including the advanced settings) and make sure they are the same (apart from things like channel which are allowed to be different).

The reason the DHCP server gives your phone the same ip is because of DHCP lease times.

This is a amount of time at which a device can disconnect the reconnect and still have the same ip assigned to them.

I take it you only have DCHP working on one of the routers, one is essentially a passthru?

Thanks for the replies guys,

I will have a look into the wireless settings, but wouldnt the fact tha the iPad is functioning perfectly on both the wireless networks rule out the fact that the network settings are an issue?

I might try download some of the apps onto another IOS phone and see if that one works. If it does, then it sort of leads me to believe that the issues is something to do with the relationship between this troublesome phone and the "Lounge" wireless router.

Is there a way to completely cleal all records of a certain wireless connection from a IOS phone rather then just the "Forget this network" button?

iPad working suggests it's not the network, but it's worth getting the network right to eliminate that as a possible cause. Just turn off DCHP on the router you consider secondary - probably the shed. DNS should probably be delegated to the main router too.
