All of the following applies to TL-WR841N(RU) Ver:8.4 About a month ago I bought a batch of 5 pcs. for installation by subscribers. Two routers have already been taken back, the other three are still silent. The essence of the problem: they stop adequately passing packets. In the first case, absolutely, in the second - about 50/50 losses both over the cable and over the wireless network. Frauds with flashing, changing ip ranges do not give results. Directly (without a router) the connection works fine, packets are not lost. I used to buy similar routers (I donβt remember the exact model), outwardly - one to one, but with removable antennas. There were no problems with them.
