Hi there,
I am new in posting to this forum, although I am not new to reading threads here. I have bought the D-link DIR-860L in the hope that it would help me to get rid of a very annoying problem: more often than not, I experience quite heavy lag when playing a movie (either through VLC, or popcorn-time), when mirroring or extendingg desktop through airplay and my Apple TV 3. I have read quite a few threads on similar problems, with most 'solutions' referring to turning off bluetooth (which helps, but not always sufficiently), or using a 5Ghz network for increased speed. Because all my devices are within the same (small) room, there are about 20 other 2.4Ghz networks, and only 1 other 5Ghz network, setting up a 5 Ghz network made sense to me.
So now I have a 2.4 Ghz, and a separate 5Ghz network. From various threads I picked up some advice on best settings for the ATV:
-N/AC
-20/40 width
-auto transmission rate
-chose a channel not used by others: 48 in my case
-enabled IPv4 multicast streams
-WMM is automatically enabled
Signal strength to all devices is very good (90-100% according to the D-Link web interface status report). Still, I regularly experience lag when trying to watch a movie through extended or mirrored desktop via airplay. By now I have spent already a huge amount of time in trying to get this right. The most abundant tips, such as turning off bluetooth and making sure there is no interference have helped, but still it is not fully stable. Does anyone have any other suggestions?
In some forums, it is suggested that it is better for airplay to disable WMM. However, this option is greyed out in the web interface for the 5ghz network.
Could there be any problems between the d-link router and my tele-2 wifi modem? I am no expert in these things, but could it be that I need to fix something with the ISP, DHCP or DNS settings? The modem (192.168.1.1) is on a different IP than the router (192.168.0.1), so I think the DHCP should then not be a problem? I have set a NAT DMZ host IP address in the modem to 192.168.0.1. I am not sure anymore, but I believe that this should ensure that the router is in charge of handing out all the IP addresses in the network without conflict with the modem?
As you can see, I am no expert, which is why I sure could use some help in these matters.
