Prehistory: some years ago I have tried to use Mikrotik rb951ui-2hnd as my home router with WiFi. I have a laptop with Intel wifi adapter and couple other n-devices like to iPad. But the performance of WiFi was slow dramatically, n-mode was slowly than g-mode. I spend a lot of time to read Internet topics about this issue but nothing to help... So, my conclusion was that Mikrotik is a good router but wifi of it unfortunately is worth. I have turned off WiFi mode in Mikrotik, connected my Asus RT-N16 as Access point and in the same conditions got full speeds of 802.11n on 2GHz. It was RouterOS 5.xx times.
Now: For some reasons I'd like to build WiFi router based on Mikrotik again Now we have 2017 year, RouterOS 6.40.5 and all 802.11n issues again I have RB435 + R52Hn + two 4 dBi antennas connected by MMCX-SMA pigtail. Speed of n-mode is toooo slow, more slow as compared with my Asus RT-N16. The situation is the same as couple years ago. Maybe somebody could help to resolve this issue?
Here is my wireless configuration:
/interface wireless set [ find default-name=wlan1 ] adaptive-noise-immunity=ap-and-client-mode ampdu-priorities=0,1,2,3,4,5,6,7 antenna-gain=3 \ band=2ghz-g/n bridge-mode=disabled country=russia disabled=no distance=indoors frequency=auto frequency-mode=\ regulatory-domain mode=ap-bridge multicast-helper=full rx-chains=0,1 ssid=Ivanov2 tx-chains=0,1 wireless-protocol=802.11 \ wps-mode=disabled
- Laptop and Asus RT-N16, 802.11n mode, 130 MBps connection - download speed is over 5-7 MB/s (Megabytes per second).
Laptop and Ruckus R500, 802.11n mode 2GHz, 300 MBps connection - download speed if over 10 MB/s (Wow!).
Laptop and Mikrotik RB435 + R52Hn, 802.11g mode, 54 MBps connection - download speed is over 2 MB/s and stable (this is normal for g-mode).
Laptop and Mikrotik RB435 + R52Hn, 802.11n mode, 130 MBps connection - download speed is lower then 1 MB/s and not stable (!!!).
