Getting Fed up Again

  • My performance has been sketchy, on again, off again. Recently things had stabilized with the last update, but now I can only reach about 1/3 of the normal wifi speed.

    I have an HD setup with 2 mesh points and an extra HD router in bridge mode. The second HD router is the one that we connect to 90% of the time. Typically we would get 3-400Mb/s throughput.

    This is more consistent with what we see these days:

    iperf Done.

    If I go downstairs to the main unit I get 400Mb/s. Rebooted the full system, still the same, and there is Cat 6 between the two units.

    Considering all of the problems that I have dealt with over the past 2 years, I think I am down to the point of waiting on one more update and if that does not fix things I might be shopping for something else, This is just becoming more of a hassle and the time cost of mucking with it is exceeding its value.

  • Also, I am on a 300Mb/s ISP plan. My office Mac is getting ~240Mb/s, normally it would be 300-310 (it is wired). The notebooks are getting ~50Mb/s.

  • This raises an interesting point for Amplifi: I bought the second Amplifi HD unit on March 7, 2017 meaning it has just fallen out of warranty.

    If I have been working for almost the whole year with your teams on troubleshooting, does the warranty really expire in 1 year? Is there any allowance for sub-optimal performance?

  • Contact support directly if your having these issues. There is a customer phone number.

  • I have been in contact with support for over a year now.

    Complete reboots of the entire system (and clients) now has me to the point were I am getting ~250Mb/s throughput, but it keeps dropping to Kb performance on most runs.

    Stepping downstairs to the main unit, I get ~400Mb/s for most runs but I still see Kb/s throughput at times.

    Thinking about heading to Costco to pick up an Orbi this weekend. They have a very liberal return policy so that would allow me to see whether the throughput issues are tied to Amplifi or not.

    My biggest frustration is that it has been a year of fighting with this system, providing support with tons of troubleshooting data, and it is still giving me issues.

  • @john-fruehe There is a known issue in 2.6.2 which sometimes drops speed to much lower than expected. You could try 2.6.3 beta.

  • @dmitrijs-ivanovs Instead of trying a beta I went and bought an Orbi at Costco yesterday.

    100% solved the Chamberlain garage door opener issue that has perplexed Amplifi for over a year. Performance is ~400-500Mb/s where Amplifi was ~250Mb/s. Haven't spent a lot of time with it but so far so good.

    I'll let Amplifi sort out their product on their own (not interested in testing beta sw, too busy to devote time to it). If the next version fixes everything then I can return the Orbi because Costco has pretty good return policies. If Amplifi doesn't come through in time or doesn't fix the issues then I may just stay with the Orbi. Clunky interface, but if that is the price for more solid performance, I'm open to the change. Still need to test out a lot of the functionality but so far I am seeing good things. But honestly would prefer to have Amplifi fix their issues so I don't have to buy something different.

  • Here's an example of an iperf run on Orbi:

    I am still seeing some fluctuations, runs have drops that are going down into the ~70Mb/s or so. Those same fluctuations on the Amplifi were down into Kb/s range, sometimes even zero. Because I am seeing fluctuations on both it may be a server issue so I will put iperf on my NAS and see if I can get readings from there.

    The Orbi handoff seemed to take a little longer. Had to stand directly over the other unit to have it handoff (signal strength dropped to -93 before it moved.) Need to do some testing in the -70 range because that is typically the threshold. Timing how long at -70 before it flips is important. At -70 it was ~50Mb/s connection and ~25% or so.

  • @john-fruehe Don't get too excited about the Orbi. They have their own issues, just as the Amplifi. I was just checking the Orbi forums and they have the same disconnect and satellite drop issues seen here. Not looking good. I think this is just indicative of mesh network setups and how new they are. I scrapped by Orbi when they first came out for an Amplifi. The Amplifi was very stable for the most part, until the end of last fall with the Kraken security update.

  • @marc-goins said in Getting Fed up Again:

    @john-fruehe Again I would get too excited. I have tried plenty of Mesh systems had was very happy with Orbi for around 6 months but it then became a nightmare! Whilst Amplifi isn't prefect, in my environment it is by far the most stable.
