I'm trying to use MIDIBridge with a diverse group of iOS devices, including * iPad 1, iOS5, 8GB *iPad 4, iOS 7, 32GB *iPod Touch 3, iOS6, 16 GB *iPod Touch 4, iOS7 16GB
I cannot get reliable connection and operation in any combination of these devices. I am using a TP-Link Access Point in a dedicated network with no other WiFi devices within 100 meters.nor any Internet at all
Sometimes my connections hold reasonably. Other times I cannot go as much as 1 minute without on aor another device dropping the connection. This applies even when only 2 devices are involved, seemingly in any combination
Even when the connections are shown okay, the operation of notes from one device to another is very erratic. Sometimes all devices respond except one. In others, I get only maybe 1 out of 10 notes. In another case, I had severely corrupted audio from the receiver.
Does anyone see anything here that can help me. Yes, ideally I would have a uniform collection of devices, but that's not how life works. Also, I'm quite unclear on the difference between a WiFi Access Point and a WiFi Router, or if there are settings of the network that could affect my operation.
Greatly appreciate anyone's help on this!

Hi Gary,
I wouldn't be too concerned about the mix of devices.
The first thing to do would be to make sure the TPLink is running the latest firmware from tplink.com
The next thing I suggest is try changing the channel that the TPLink is running on. There may be some other RF (radio frequency) interference present that is causing these woes, especially given that it happens with just two devices.
There are some settings wifi-wise in the router that might be tweaked to favour the type of traffic that wifi-RTP represents. Someone at one stage send me some info on what they used with a dlink router, which I have just managed to locate:
I also recently changed some parameters on my router to optimize transmission to iOS devices and it seems to have made a big difference with the release ( on my DLink DIR-655 it involved setting Beacon period to 75, and both RTS Threshold and Fragmentation to "2304")
You could try adjusting those in the TPLink.
What is the model number of the TPLink device?
Your wifi is going to be very dependent upon the router/access point. If at all possible (after the above options are exhausted) maybe you could borrow a different brand router from somewhere and try that also. I have TPLink routers here (1043 and 841 models) and have not experienced problems. I should concede that these are running openwrt and not tplink's firmware though.
My gut feeling is that there could be some RF being blasted around the place that is disrupting things. There are little dongles (I have the one from metageek) that you can use in a computer to monitor what is happening RF wise which is an option too if things get desparate.
Regards, Nic.

Thanks, Nic. I'll have to check the model number, and I admit I haven't a clue what those parameters you mentioned are. The TP-Link technician promised to visit me though. I'll print out your note.
What I have is called and 'Access Point'. i saw that there were also 'Routers' and you mention using TPLink Routers. Is there a difference that would be significant here? I'm sure I can exchange for another TP-Link model if needed.
I'll look outside for any big antennas. I doubt I'll get as far as actually metering RF there. It's a relatively remote location in the hills.

Hi Gary,
An access point is designed to 'bridge' the wireless devices so that they inter-operate at the ethernet (lower) level. A router will operate at the protocol (higher) level. However, an access point would still need to do some routing between the wifi-devices and the ethernet network. A router would also bridge the wifi devices in any case, so in theory it won't make s difference. Having said that swapping for a different unit may help but not because one is marked as a router and another as access point, but purely because they run different firmware.
If you have a TPLink technician coming then he/she may be able to do the changes/suggestions (except flashing with openwrt) above and maybe will bring tools to measure the RF state of play too.
Regards, Nic.
