The last few months I have been on a TL-WR841N without any real issues. Though the previous occupant of this studio used to have problems with it. I tweaked the security though to not broadcast the SSID and added a MAC filter, which may or may not be keeping externals out. Received the TL-MR3020 today to provide me with a network during the next 2 months, 'til I can return to the studio I am currently living at. Mostly bought it because it can easily be turned into a piratebox.cc
when I am done with it. Didn't have any problems the ~2 hours I was using it though.
