After having a lot of trouble with a UBNT Airgrid that had BBHN firmware installed (poor reception, unable to connect to other nodes unless in very close proximity), we flashed it back to UBNT firmware in hopes of returning a possibly defective device. However, we noticed that after flashing the unit back to UBNT firmware a site survey revealed around 30 plus sites in view vs around 11 sites with the exact same physical conditions only minutes before the switching firmware.

This leads us to believe the hardware was ok, but there was something in the BBHN firmware that was causing the issue. Has anyone else seen this problem with using an Airgrid for BBHN and getting poor reception? Any suggestions to try to get it to work, or do we need to just send it back and get a Bullet instead. Thanks.

What was the "last seen" time on those networks ?

We throw out anything older than 5 seconds in the BBHM GUI IIRC.  I've seen cases where 30+ Networks show up in the backend but were only getting one beacon packet every 10 seconds (beacons are normally sent 10 times a second) so it doesn't make sense to keep them listed if we are loosing over 99% of packets are being lost.

Thanks for the reply. Not sure what the last seen time was. Probably greater than 5 seconds. That would explain the 300% difference in the number of networks seen. However it doesn't explain the poor performance of our Airgrid. I guess it's time to send it back and see if a different piece of hardware performs better. Have others experienced poorer performance with the Airgrid vs Bullet? Is that typical? Thanks Brandon, K7BBR

If you do find out that BBHN does indeed have a significantly less performance let us know as we always want to improve.

I will point you at this forum post, it  doesn't answer airGrid vs bullet directly but does give a bit of feedback on one users experianxe with airGrid's.
