I have bought 4pcs WRT300N and 10 pcs of WMP300N. I installed them in a 4 floor building and put one WRT300N on each floor. I connected the first WRT300N to ADSL connection and connected 3 others to the Switch of the first one. But, the connection is not good. The maximum speed we get is about 54Mbs and sometimes the WMP300N can not connect to WRT300N. I have changed the mode to Access Point. After sometimes, the connection gets slow and disconnects. Please help me how to solve this problem.
