uTorrent 2.0 loads the Zyxel router unnecessarily (and not only)

In recent days, the Zyxel P-2602HW EE router began to behave completely indecently - it constantly lost WiFi, did not allow it on the menu, and even its reboot did not help. Well, I think it's time for you, brother, to the garbage.

But first I decided to experiment. Who is the main user of the router? That's right, torrent rocking is a separate small computer on a dual-core Atom. I unload uTorrent from its memory, and the router immediately lets me into the menu and generally behaves kindly. I turn on uTorrent back - opachki, processor processor load 100% and hanging. I unload uTorrent - again everything is great.

I remember that I recently updated uTorrent to version 2.0 and was wildly pleased with the improvements in the interface. Give, I think, otkachus back. I rolled back to 1.8.5, and was surprised to note that the CPU load on the router remained high, but it does not reach the dependencies. 70-90 percent is also a lot, but not prohibitively much.

Out of curiosity, I try 2.0 and immediately get the hang.

Now rolled back to 1.8.5. finally. Strange, very strange, because everyone in the forums screamed that version 2.0, on the contrary, was less load-bearing. Get it. I downloaded another beta 2.1, but I probably will not bet. From the good of good not looking.

And I will change the router as soon as I get a model with ADSL, 802.11n and gigabit Ethernet. There are already test samples, soon they will get to the counters.

PS By the way, from places they report that the same problems are not only with Zyxel. Say, D-Link has the same picture.
