    Default Laguna Version & Hardware Revisions (GW2388)

    I've just replaced a Laguna in the field with a new Rev H (Laguna GW2388-4-H) and it's rebooting a few times per day.

I have complete confidence in current product and have been depending on them for my backbone links with up-times of over a year with no issues. I'm running 4.1.12 and 4.2.3 with 11n so the 11n support must have been before that. I'm only running one chain though. Maybe the 4.1.12 code can be compared to a later version to reveal where the difference lies that is causing the issues.

    I'm wanting to replace all of my older Avila WAR-2 boards with new Laguna boards but just waiting for a stable release that supports all frequencies.

    I keep a consistent replacement stock of mini-PCI radios so I don't use the Ventana. Also, the Laguna has the same footprint as the Avila so it makes an easy upgrade. Just make sure to glue on a heatsink and they are bulletproof.

    Andy - what mini-PCI cards are you using? We've used the Compex N cards of course, but they are so low power and when we replace a radio with a WAR1B @ 30 dBm the client signals and their rates and throughputs to up SO much. But, in a Laguna, it would be good to know what Mini-PCI cards you're using with success please.

    Hello Andy - I've just replaced a Laguna in the field with a new Rev H (Laguna GW2388-4-H) and it's rebooting a few times per day. It's on regulated 5 AMP power, and it's replacing a WP188 which ran for weeks at a time (but only had 'g' cards in it) and when one of the 900MHz cards was dieing, I had to climb anyway - so it seemed like a good time to upgrade. But we are seeing reboots all over the place now...

    I'm not a fan of any of the multi-port boards, but since we can't replace the Lagunas all the multi-port boards with WAR1B's yet, and since we have 5 new Laguna's here and wanted to 'upgrade' the WP188 - but for us, even in spring weather, with the Gateworks Heat Sync, and even with this version 4-H board, it's rebooting a couple/few times per day.

    So - if you're not having any issues with the 4-H hardware, what StarOS firmware are you running on there?

    This is the board info:

    This is also the type of errors we see in the KERNLOG.

    Did you try the latest fw?
    There was a lot of fixes all through the various laguna revisions

    I have them on all the various fw's. As the newer revisions came about, Tony kept tweeking. Right now I use the 4.4.5.6 on all the boards I reconfigure and put into service.

    OK. I was going from what Andy said, which was with 4-H revisions he was running 4.1.12 and 4.2.3 with no issues. I can certainly try a later version, although Lonnie said that what I've been reporting as a WAR1B problem for the last 20 Months apparently affects all platforms. What firmware version do you recommend on Lagunas?

    Andy - what mini-PCI cards are you using?
    Or anyone? If there is anyone here at all? What MiniPCI cards can anyone recommend as a HighPower 802.11n card for an AP sector - 2.4ghz?

    We've tried the MikroTik R52Hn and R52HnD cards, but they give wonky signal results in StarOS. We've tried the XAGYL cards, but they give wonky power results in StarOS. And of course the Compex cards are so low power that everyone's RX rates suffer and then everyone takes so much air time. If we could move people up to MSC15, that would really really help the amount of air time everyone consumes. So - what 802.11n Mini-PCI cards are people using with HighPower? Thanks.
