    Default War 1a WLMWLM200N5-26ESD 2 jump backhaul throughput problem

    Hello

    I have a 2 leg backhaul with War1a run StarOS V1.5.16+
    WLM200N5-26ESD Radios

    Using UBNT Rocket 5G34 dishes.
    100% Quality -55 to -60 signal -90 to -95 Noise Floor
    Connect Rate 130 X 130
    Midpoint Ethernet Boards connected with HP 10/100/1000 Switch

    I also have a UBNT Backhaul parallel to this one.
    Both networks have RFArmor Shield Kits

    On the UBNT backhaul I can pass 60 to 80 Meg Throughput.
    On StarOS I am only seeing about 14 Meg Throughput.

    What do I have to do to get the StarOS systems to perform like the UBNT?

    Thanks

    PM me with a login and I'll take a look. Any chance you have the cables swapped? That really affects the throughput although the signal is measured as being high. You get a strong signal but the wrong stream and the cards have to dig the lower signal with the proper stream out of the noise.
    Don't take life so seriously. It's not like you're going to get out alive.

    Something must be wrong there. I have several P2P links using WLM200N5-23ESD on 1x1, wpa2, ccmp, connect rate 65 or less. They typically run 40 Meg. One only does 30. Make sure you are using wpa2 and ccmp. Otherwise you will run at 11a rates and 14Meg wouldn't be a surprise. Also make sure you've specified aggregation; it makes a huge difference.

    Hello handyman

    Currently we are not running any encrytion on this link until we figure out the throughput.

    Question You still may need ccmp

    802.11n draft versions specified 802.11a only if you are running open, and required ccmp for 802.11n. Your card may be enforcing that.

    Check the rx and tx rates to see whether they are 802.11a rates (54, etc) or 802.11n rates (65, etc).

    The War1a with the WLMWLM200N5-26ESD is reporting N rates and the War1a can be locked to N only.
    I am assuming Lonnie and Tony would know the answer. I don't see anywhere to set ccmp? I'm a relative newbie,
    less than 5 years in fixed wireless, less than 1 year in StarOS.

    If your system is open (not encrypted), then you will have full HT support. HT rates are restricted when using WPA however, if you are not using CCMP.

    The trouble with programmers is you can never tell what they are doing until it’s too late.

    Unhappy WEP too.

    And HT rates are restricted if you use WEP. It shows up in the tx and rx rates.

    Question Try it?

    Would it really be so difficult to put it into WPA2 + ccmp and see what happens? There's nothing quite as good as actual data...

    That is correct. It is TKIP and WEP that are not HT friendly. WPA w/ CCMP is needed for HT, if you require security with no performance penalties
