Hello, I have 3 R510's in my home. 1 for each floor, ceiling mounted and placed central to each floor. None of the clients on our network can ever achieve more than 50Mbps. My PC which is 15ft around a slight corner from the AP got 30 Mbps down and 80Mbps up on an AP to Client speed test.
I don't want to generalize it but you could try tweaking below settings and see how much it can improve.
- Enable the OFDM. - Set BSS min rate set to 12 Mbps. - Enable band balancing and force clients to 5G radio. - Disable overlapping channels on 2.4 G radio. - Set channelization to 40 for 2.4 Radio and 80 for 5 Ghz (though it depends upon clien UE wireless capabilities what max speed it can achieve). - Disable the self healing. - Change scanning mechanism from channel fly to background scanning (set it to 600-1000 for 2.4 G and 600 for 5G). - Enable 802.11N/AC only (Assuming that you don't have very old devices which only supports a/b/g and not n/ac). - Set tx power to full (If it was modified to lower values manually).
Also I want to point that R510 APs can maximum support upto 867Mbps (if UE supports 802.11ac and connecting to 80MHz in ideal conditions).
Thanks, I just got an 802.11ac adapter and my bandwidth is now around 200mbps. With 30+ clients connecting (smart home stuff everywhere) as well as my wife working downstairs, I think this is a pretty acceptable rate. I'm going to try the changes suggested above to test and see if there is any increase, I suspect anything at this point is incremental.
