I'm using an R52Hn radio card in a RB411AR with ether1 and wlan2 bridged. My 411AR connects via a 3M cable to a 2.4GHz 12dBi Vertical Omni Antenna the specifications of which are:
- Frequency Range–MHz: 2400-2483
- Bandwidth-MHz: 83
- VSWR: ≤1.5
- Input Impedance -Ω: 50
- Polarization: Vertical
- Maximum Power-W: 100
- Connector: N-Type Female
- Gain-dBi: 12
- Vertical Beam-width: 7
My RB411AR wlan2 interface settings are:
Mode: ap bridge
Channel Width: 20/40MHz HT Below
Frequency: 2462 (as this was the most inactive with no other visible networks being effected using inSSider)
Wirless Protocol: 802.11
Security Profile is WPS2 (I had to enable aes as tkip only for some reason meant users could not authenticate)
Antenna Gain: 0
DFS Mode: None
Prop. Ext: port-2.9.25
WWM Support: Disabled
Bridge Mode: Enabled
Def. AR Tx Rate: Greyed Out
Def. Client Tx Rate: Greyed Out
Def. Auth.: Ticked
Def. Forward: Ticked
Rate Selection: advanced
Rate: default selected
Area: Greyed out
Max Station Count: 2007
Distance: Indoors (even though its actually outdoors; I read of another user on the forum having better results selecting indoors.
Rest of the settings are left as default.
HT Tx / Rx Chains 0 and 1 selected
HT AMSDU Limit: 8192
HT AMSDU Threshold: 8192
HT Guard Interval: Any
HT AMPDU Priorities: 0 is ticked rest are not
CSMA not disabled
Sec.: not enabled
No preshared Key
Power Mode: card rates
TX Power: 22
Tx CCQ: 52%
Noise Floor: -114 dbm
Using inSSIDer I can see my network is not interfering with any other networks listed and that my Max rate is 300N (using channel 11+7) where before it was 54.
Looking at the "Wireless Network Connection" status from a laptop running XP very close to the antenna and using a Dlink DWA-125n USB Dongle it shows speed as 135.0 Mbps where before it was 54Mbps
Repeating the above from a laptop about 10-15 Meters away using a Planet UT-WNLU55(n) USB Dongle behind 2 glass windows and a brick wall the same is true though i seem to recall the speed fluctuating somewhat.
Torching either one of the above laptops under Wireless Registration in Winbox shows speeds that range from 13Mbps to 30Mbps where as before installing and setting up the R52Hn and using the 411AR's b/g on board radio speeds would not reach above 20Mbps.
Having said the above if I was not torching / monitoring the speed at which media is downloading from my PC I would be hard pressed to notice a real life difference for the better, the indicators suggest they are yet its hardly noticeable (esp. from the laptop furthest away.)
How can I (by way of settings) improve the speed at which data / media is being transferred and do I have to upgrade my antenna's / dongles to achieve this?
Suggestions very much appreciated.
