I have a set of three Deco 60s. They are optimally placed in the house, with a wired backhaul (through an unmanaged switch with ample excess capacity), and show great internet speed, both on the Decos (920mbps up and down) and on devices (500mbps up and down on an iPhone, more on a laptop).
But transfers between devices, for instance between the NAS and a laptop, can get at times creepily slow, in the order of kbps. Restarting the main Deco often resolves the issue. More interestingly, if I run an internet speed test on the Deco while a slow transfer is ongoing, suddenly the transfer accelerates and comes up to speed, but then dropping as soon as the speed test is finished. What kind of a wizardry is this? How can I check what is wrong?
@TP-Link Here is the network diagram:
I have experienced the slowdown on two devices (TV and Notebook), both connected to the main Deco, sitting between one and three meters away from the Deco. The NAS is also connected to the main Deco, but via an unmanaged gigabit ethernet switch
The issue has occurred several times, but the timing is pretty random and often hits when streaming to the TV. Restarting the NAS doesn't help. Restarting the main Deco does help. I have observed this on both TV and Notebook. Running an internet speed test on Deco also seems to solve the issue temporarily, this I have tested this on the Notebook several times. Since I don't know how to reproduce the slowdown, I can't retest the internet speed solution on another device (that is, on the TV). But I remember having the same issue on the TV using a wired connection. Meanwhile, streaming from the internet seems to work fine, or at least the slowdown is subtle enough not to be noticed.
When I access the NAS I normally use the mDNS address (mynas.local), but I can't be sure I have done this every time. I have used a SAMBA share on the Notebook, while the TV transfers the data either using Plex or DLNA.
I also have to note that enabling the internet security features (intrusion prevention, etc) results in the same type of slowdown within the LAN, and then nothing helps until I disable all the options (I don't know exactly which option creates the issue, Malicious Content Filter or Intrusion Prevention System).
