My iOS devices don't play well with RT-68U

[ryarber]

I am running the latest (.42) build of Merlin firmware. This is not a new issue for me as I don't think I've ever gotten really good connection between the 68U and the iOS devices.

It seems they drop connection frequently and often after waking them from sleep, it takes a bit for them to get WAN connection.

My apple laptop doesn't seem to suffer the same issues, and when I connect to my AirPort Extreme in another part of my house (yes, I have a huge house), my wireless issues go away. I'd be happy to submit logs or do whatever I need to do to troubleshoot these issues. And I'm sure other iOS users have had these same problems.

My current network consists of the RT-68U acting as the main router with an AirPort Extreme and an airport express each set up in bridge mode hard wired to my network backbone.

The other thing is my iOS devices suffer with throughput issues when they are connected and getting good signal. I have a 50Mbps broadband. My laptop will get full bandwidth usage, but my iOS devices struggle to get half that.

Is there some setting I haven't done right? I've tried to play with beamforming, etc but I haven't gotten anywhere.

Universal basic troubleshooting steps are in link below.

My guess is that you are using the same SSIDs and that is the source of your problems. But that's just a guess.

I actually have a separate SSID for each device.

iOS devices are sensitive when you change a wireless router to another wireless router then using the same SSID. I'm not sure if that's your situation, if it is, delete/forget the profile from the clients then start over.

With the older ios devices I use, I'll get drops if I enable wmm no-ack, optimize ack-suppression, and/or optimize ampdu aggregation. With these disabled, I get a pretty solid connection on 2.4ghz. I believe most, if not all of these are disabled by default.

Update to my issues.

I went back and assigned a different SSID to the 2.4 and 5 GHz bands on my router and access points and that didn't seem to make much difference. There is one thing I did that seems to have made a huge difference...

I had assigned many of my devices their own IP addresses outside the DHCP range. Those that are on the network often. By my logic, this reduces stress on the router by not having to keep up with assigned addresses. I have a lot of devices in the house and I try to assign most of them their own IP addresses.

When I changed my iPhone back to DHCP and assigned it an address in the router, it seems to have made most of my problems go away.

So, my question is this... Does anyone else have their iOS devices assigned an ip address from within the iOS device and does it seem to make a difference to you as far as connection reliability and throughput?

I have a iPad 2 and my daughter has a iPad mini no issues with either both stay connected and get full speeds 52/11 using AC68U.

my iPads don't seem to have problems either, just the iPhones

iPad Air works great. Just switched from the iPhone 4S to the LG G2. LG G2 is AC so it is much faster than the 4S.
