Oh 3.10.28-1, my working place and the router position are badly = matched, so I only get 80 to 150 mbits/s there, but it is nice to cover = the full flat with one router, so I will have to live with that. = Question to all, I have set up my WNDR3700 on the vertical stand on a = shelf above my head, is that the ideal position or has anyone other = recommendations how to rotate the router?
