Answer 3

With Zyxel keenetic giga I had a sad experience of communication. I bought a new one in Yulmart, I was happy for 2 months, then I saw something strange - the speed via lan is not higher than 20 mb / s, but if you plug the Internet hose directly into the PC - the required 90 mb / s like a watch, everything was fine on wi-fi too. Half the night I sat, sewing different versions of firmware - the result is zero. In the morning I could not stand it, I ran to Yulmart to take it. After 2 weeks, the result: Khan switch, can not be repaired, we will return the money. Moral: but there is a hole in the unkillable Zyxel
