Re: [WISPA] Powerstation2 with very low throughput
Thank you all for your responses. I change the AP to B mode only, then set the ACK manually and now it's performance is on par with the Tr6600 we had before. I also changed 1 client to another AP.

I've been checking all the clients, and I see some of them with very high retries. They are pushing through trees. Could be a likely cause right? Excessive retries can definitely cause a severe reduction in throughput. Here's a study I did a year or two ago. The test was to see how many retries a typical 802.11 AP/station would send before giving up. I was surprised. This particular test run was to see how effective MikroTik's frame lifetime setting was. Static test configuration 2 * AP, 802.11b, channel 1, ROS 3.3 * Engenius station * RB112 w/ NMP-8602 station, ROS 3.3 * RB112 w/ NMP- sniffer, ROS 3.3 Test run 2.1 * Dynamic test configuration o AP, 802.11b, channel 1 + hw-retries - 4 + on-retry-fail-time - 100ms + disconnect-timeout - 3s + frame-lifetime - 0 (infinite) * Results o Max observed frame retry count - 185 Test run 2.2 * Dynamic test configuration o AP, 802.11b, channel 1 + hw-retries - 0 + on-retry-fail-time - 100ms + disconnect-timeout - 3s + frame-lifetime - 0 (infinite) * Results o Max observed frame retry count - 76 Test run 2.3 * Dynamic test configuration o AP, 802.11b, channel 1 + hw-retries - 0 + on-retry-fail-time - 100ms + disconnect-timeout - 3s + frame-lifetime - 10cs (100ms) * Results o Max observed frame retry count - 7 Test run 2.4 * Dynamic test configuration o AP, 802.11b, channel 1 + hw-retries - 0 + on-retry-fail-time - 100ms + disconnect-timeout - 3s + frame-lifetime - 1cs (10ms) * Results o Max observed frame retry count - 4 (1x11Mbps, 1x5.5Mbps, 1x2Mbps, 1x1Mbps) Test run 2.5 * Dynamic test configuration o AP, 802.11b, channel 1 + hw-retries - 4 + on-retry-fail-time - 100ms + disconnect-timeout - 3s + frame-lifetime - 1cs (10ms) * Results o Max observed frame retry count - 4 (4x11Mbps) These tests are counting AP-side retransmits, but the same applies to the CPE. When we have a suspect client with a MikroTik CPE, we login and change frame lifetime to ~10. If it completely breaks them, then we know they're (part of) the problem. In an extreme case, we had to put another AP up in sniffer mode to find the culprit. In more than one case, the problem was a metal barn either directly in front of the customer's antenna, or at the half way point. HTH, -Kristian WISPA Wants You!

Re: [WISPA] Powerstation2 with very low throughput
Take the cover off and look at the connectors on the board. They are hot glued on but the ones I had go bad, the glue became brittle and broke off. I found that the connector to the board was very loose. As in, too big to snap into the board. A manufacturing snafu I suspect with a nice amount of hot glue keeping it on. Mine started in the spring after being up for a winter. They would come and go, levels up and down. Eventually burned out the boards. Replaced the boards with the Light Station boards. Have to remove the power connector though. The ones that didn't burn out and still seemed to have good throughput, I just replaced the N connectors. On the connectorized versions that is. I really WAS amazed to see the connectors just fall away with the glue removed. I still have 2 in the living room in pieces. Did an RMA on them but never sent them in. Always too much going on.

Re: [WISPA] Powerstation2 with very low throughput
My guess would be the low symbol rate you have on a few clients. Try getting their signal better, or temporarily disabling them to see if that helps. Chris Gotstein, Network Engineer, U.P.

Re: [WISPA] Powerstation2 with very low throughput
With Ubiquity gear the normal / standard for troubleshooting is
something like this:-
... Update to the latest firmware (from their site)
also review what fixes in the latest beta (posted in the forum)
Try setting up your AP without Auto Ack and setup the Ack distance
manually.
