Hi,
This is my first post as I encountered issue which started to bother me a lot - wireless speed
short topology:
modem → RB951Ui-2HnD–> client
problem:
- speed between modem and mikrotik: ~90Mbps/20Mbps
- speed (via Wifi) between client and Mikrotik: ~ 40/20Mbps
- speed (via eth) between client and Mikrotik: ~ 80/20Mbps
it’s not a client issue, as if connect directly do modem (it have Wifi as well, although I’m not using it) I get 90/20 speed.
What can cause such drop of speed on WiFi connection via Mikrotik ? It’s not a range, I’ve checked 
basic output from wireless interface print:
Flags: X - disabled, R - running
0 R name="WIFI" mtu=1500 l2mtu=1600 mac-address=E4:8D:8C:B7:10:27 arp=enabled interface-type=Atheros AR9300 mode=ap-bridge ssid="CocaColaLight"
frequency=2462 band=2ghz-b/g/n channel-width=20/40mhz-Ce scan-list=default wireless-protocol=802.11 vlan-mode=no-tag vlan-id=1 wds-mode=disabled
wds-default-bridge=LAN wds-ignore-ssid=no bridge-mode=enabled default-authentication=yes default-forwarding=yes default-ap-tx-limit=0
default-client-tx-limit=0 hide-ssid=no security-profile=main-profile compression=no
any ideas what can be changed to improve speed ? difference is way too huge
