Miki-Ap vs Intel Wifi Link cards

RouterOS Wireless Networking
1

Hi All!

I’ve tried several MT RB as AP

  • RB950G-2HnD,
  • RB950Ui-2HnD,
  • RB941-2nD,
    with Intel Wifi Link cars
  • Intel Wifi Link 5100 (3x antennas),
  • Intel Wifi Link 5300 (3x antennas),
  • Intel Cenrtino Advanced-N 6235 (2x antennas).
    The max connection speed always 135Mbps: 135Mbps-40MHz/1S.
    Always use only 1S :frowning:(
    I enabled (checked) Rx/Tx Chains: Chain0 and Chain1.
    There is no difference between CAPsMAN and AP mode :frowning:
    It is my fault?

I have test with Intel 7620 AC and 6300 N

it Was working grate in Dell Latitude with win7/8/10 And arch linux
Connected all available chains.

what drives do you use in what laptop ?

The RB951Ui-2HnD, RB951G-2HnD and RB941-2nD have only two chains as far as I know and 40 MHz wide channels probably aren’t possible in your area. More information on this topic: http://www.smallnetbuilder.com/wireless/wireless-features/31743-bye-bye-40-mhz-mode-in-24-ghz-part-1

135 MBit/s Tx Rate is completely normal with this setup.

Thx for the tipp!
I’ve made a quick test:

  1. Dell Latitude E6400
    Windows 7 Pro x64
    Intel Wifi Link 5300AGN, driver 2012.01.22. - 14.3.2.1
    Connet with 2S

  2. Lenovo G550
    Windows 7 Pro x64
    Intel Wifi Link 5100AGN, driver 2012.01.22. - 14.3.2.1
    Connet with 1S

3/1. Hp ZBook 15
Windows 7 Pro x64
Intel Centrino Advanced-N 6235, driver 2014.11.17. - 15.15.0.1
Connet with 1S

3/2. Hp ZBook 15
Windows 7 Enterprise x64
Intel Centrino Advanced-N 6235, driver 2014.01.26. - 15.11.0.7
Connet with 2S

Intersting :slight_smile: I"ll try some version of Intel driver.

I Was using 2015 Drivers. But sill 2S still be used if 20mhz is choose. How you are generating traffic when testing ?

6

“How you are generating traffic when testing?”

Ohh! I have to generating traffic while testing? Nice! :slight_smile: I’ll test again :slight_smile:)

“135 MBit/s Tx Rate is completely normal with this setup”

Correct/complete the first test result:

  1. Dell Latitude E6400
    Windows 7 Pro x64
    Intel Wifi Link 5300AGN (3x antennas), driver 2012.01.22. - 14.3.2.1
    Connet with 2S → 270Mbps-40MHz/2S
  2. Lenovo G550
    Windows 7 Pro x64
    Intel Wifi Link 5100AGN (2x antennas), driver 2012.01.22. - 14.3.2.1
    Connet with 1S → 135Mbps-40MHz/1S

3/1. Hp ZBook 15
Windows 7 Pro x64
Intel Centrino Advanced-N 6235 (2x antennas), driver 2014.11.17. - 15.15.0.1
Connet with 1S → 135Mbps-40MHz/1S

3/2. Hp ZBook 15
Windows 7 Enterprise x64
Intel Centrino Advanced-N 6235 (2x antennas), driver 2014.01.26. - 15.11.0.7
Connet with 2S → 270Mbps-40MHz/2S

I don’t think you need to generate any traffic. This is only the Tx Rate. Real throughput would be way lower anyway.

Are you somehow forcing 40 MHz channels?

9

“Are you somehow forcing 40 MHz channels?”

How can I make it?

10

You shouldn’t, that’s the point. From what I can see you use 40 MHz wide channels, but that’s only possible if the 2.4 GHz band is completely free of interferences (which is extremely rare). You could switch to the 20-MHz-only option and see if it helps.

“You could switch to the 20-MHz-only option and see if it helps.”

Ok, I use only 20MHz. But Intel Wifi Link still uses /1S (65Mbps-20MHz/1S).
I would like to see 130Mbps-20MHz/2S
